Abstract:

The author approaches the subject of translating for theatre both as a theatre practitioner and professional translator working in three languages. Translation is generally regarded as process of linguistic transfer from one language to another language in written form. Theatrical texts are an unique literary form because their written form is a base, anchor and springboard for the text in performance. Until recently, translation studies have tended to oscillate between lofty pronouncements which remain too general to be easily applicable to the practical task of translating and close textual analysis which may appear fastidious and overly specific. The art of translation has often wanted to call itself a science, thereby ostensibly increasing its credibility. However nowhere more in the context of theatre can it be justifiably called an art, with all that entails in terms of subjectivity, cultural bias and transitory or timeless validity. There is no such thing as a perfect translation. Translation is a process of endless learning. Several translation theorists have offered broad categorisations or lengthy rationalised lists to help define the parameters of this most tangible practice. No such lists exist which addressed the specific criteria of translation for theatre. Through personal experience and critical reflection, this thesis will offer the beginning of a blueprint which may be useful for translators working in this field

Abstract:

O transporte marítimo de petróleo e derivados é componente fundamental da cadeia de suprimento da indústria do petróleo, integrando fornecedores e clientes localizados em regiões geográficas distintas. Neste contexto, os valores de fretes praticados possuem grande impacto no comércio internacional destes bens. O objetivo deste trabalho é verificar o desempenho de modelos de Regressão Dinâmica em previsões de frete marítimo de curto prazo do mercado spot de uma rota de exportação de petróleo do oeste da África para a China, comparar a capacidade preditiva do modelo com métodos tradicionais, vastamente discutidos na literatura, como Amortecimento Exponencial e modelos ARIMA e projetar cenários para avaliar como as variáveis explicativas presentes no modelo de Regressão Dinâmica proposto neste estudo afetam o frete marítimo. O produto desenvolvido nesta dissertação mostrou a viabilidade de os modelos univariados e causais serem utilizados como ferramenta de previsão da taxa frete de navios petroleiros. Como forma de validação, os resultados foram comparados aos obtidos com a metodologia vigente em uma grande empresa de petróleo do Brasil. O protótipo de sistema de previsão proposto, via Regressão Dinâmica, apresentou resultados satisfatórios e desempenho superior ao obtido através da metodologia da empresa de petróleo.
Crude oil and oil products seaborne transportation is a key component of the petroleum industry supply chain, integrating suppliers and customers located in different geographic regions. In this context, the freight rates practiced have a great impact on the international trade of these goods. This work aims to verify the performance of Dynamic Regression models in short-term maritime freight forecasts of the spot market of an oil export route from West Africa to China, to compare the predictive capacity of the model with traditional methods, widely discussed in the literature, such as Exponential Smoothing and ARIMA models and to design scenarios to evaluate how the explanatory variables present in the Dynamic Regression model proposed in this study affect freight rate. The product developed in this dissertation showed the viability of the univariate and causal models being used as a forecasting tool for the oil tankers freight rate. As a form of validation, the results were compared to those obtained with the methodology of a large Brazilian oil company. The proposed prediction system prototype, through Dynamic Regression model, presented satisfactory results and performance superior to that obtained through the methodology of the oil company.

Full text

Abstract:

The present work is conducted within the context of air to air refuelling technologies and aims at the development of an understanding of a typical refuelling tanker wake like that of an A330 [54] and the A400M [54]. The wake is particularly investigated within the near field and extended near field wake regions in close vicinity to the rear fuselage. Moreover, the interaction between the wake and the refuelling hose is studied including the resulting hose characteristics. A number of refuelling conditions and aircraft models are considered for the investigation of the wake. Moreover, an arbitrary hose fairing model is considered to study the effect of the fairing on the flow field and the refuelling hose. Different refuelling configurations are taken into account for the investigation of the hose characteristics. Various hose exit positions were studied within the near field wake to assess the impact on the hose characteristics. The probe hose engagement with the associated hose whip phenomenon is a major topic within this work. The hose whip is a highly undesired phenomenon and is amplified by a specific hose shape which is characterised through an inflection point along the hose. The present research reveals that the rear fuselage wake has a crucial impact on the hose characteristics. In particular, the rear fuselage upwash is the primary cause for formation of the undesired hose inflection point. The findings obtained from the present research are used for the suggestion of palliatives to avoid undesirable hose characteristics. In particular, there is one approach recommended which aims at the avoidance of a hose-upwash interaction. It leads to the suggestion of a circumferentially shifted and radially displaced hose exit and deployment of the refuelling hose.

Abstract:

The oil tankers that operate on the Trans-Alaska Pipeline Service (TAPS) route have exhibited a large number of structural fatigue cracks. These cracks can be attributed to the increase in use of high strength steel in tanker construction and to the harsh operating environment in the Gulf of Alaska. In response to the TAPS fatigue problem, this project examines the topic of preliminary design for fatigue resistance. The TAPS tankers have previously been the target of several studies on the subject of fatigue cracking. Most of these studies have concentrated on reducing the costs and risks involved with operating the current tanker fleet. Preliminary design, however, is oriented at reducing the fatigue risk in future tanker designs. To that end, the design method outlined within concentrates on the level of analysis that is appropriate for preliminary design. The design method consists of four steps: the specification of a wave environment, generation of a hydrodynamic model and subsequent wave loads, evaluation of cyclic stresses and an assessment of fatigue damage. A series of example calculations that is typical of preliminary design has been performed for one of the TAPS tanker classes. These calculations employed Buckley's climatic wave spectra, a 3-dimensional panel based hydrodynamics package by Lin and a Miner's rule fatigue assessment based on the S-N curves of the British Welding Institute. The example calculations yield two important results. First, relatively inexpensive methods can yie1d important and accurate fatigue results; for a side shell longitudinal at the water line the example calculations predict a fatigue life of approximately 3 operating years. This corresponds quite well to the published inspection data and obviously represents insufficient fatigue life. Second, local panel pressures can have a significant contribution to, and even dominate, total fatigue damage in the side shell. This contrasts with conventional fatigue studies of ship hulls which focus on global loads; i.e., hull girder bending.

Full text

Abstract:

Equilibrium is the name of a ballast-free oil tanker concept invented by naval architects at Det Norske Veritas (DNV) and further developed in this master’s thesis at the Norwegian University of Science and Technology (NTNU). The task is to analyze the conceptual design work done by DNV and further develop the concept. The main focus is on a cost comparison with a conventional tanker with a deadweight equal to Equilibrium and a conventional VLCC. The cost comparison focuses only on the costs that are expected to be different in these designs: Building costs, fuel costs and the cost of ballast equipment and operation. This comparison serves as an indicator of the profitability and thereby feasibility of the design. A trapezoid shaped hull and longitudinal cargo boundaries make Equilibrium independent of ballast in transit and during loading and discharging. The ballast-free return legs result in a significant annual saving of fuel and CO2 emissions. This is Equilibrium’s main advantage over a conventional design. Equilibrium’s main disadvantage is that the cargo capacity is about 60 000 tons lower than on a conventional VLCC. This again affects the cost efficiency of the ship. Since Equilibrium is bigger than the Suezmax limitations, the VLCC is regarded as the main competitor. A cost-efficiency index of the relevant life cycle costs over 10 years divided by the amount of cargo delivered in the same period, shows that Equilibrium is a profitable design. Further analyses needs to be done on the ship’s sea keeping abilities with special attention to accelerations in roll motion. The proposed Equilibrium design can compete against existing tankers on both cost-benefit and environmental impact.

This work analyzes the market characteristics of future oil tanker operations with a particular emphasis on those aspects which will have a potential impact on the design of future vessels. The market analysis model used is unique in that it segments historical distributions of time charter equivalent rates to account for market variability in ship design. Market cycles, trade routes, refinery locations, cargo prices, and fuel prices are all targeted as key evolving factors over the next twenty-five years and are considered in a sensitivity analysis on metrics of profitability and tanker operations. The study's analytical approach to accounting for market factors in speed selection can serve as a tool for shipowners in scenario planning by better preparing them for projected market conditions. It is intended that shipowners and operators would refer to this analysis in conjunction with market forecasts to determine which speed a ship should be designed at to maximize return. If the market is expected to be reaching a peak, this study's model can determine how much higher TCE rates need to be than historical values to justify speeding up by a given increment. Though slow steaming saves costs when the market is down, to fully take advantage of market peaks and maximize profit over a ship's lifetime, ships must have sufficient reserve power.

The tanker industry covers all business related with trading tankers in which there are many participants: vessel owners, charterers, shipbuilders, scrappers, consultants, capitalists, brokers, insurers, surveyors, agents, repairing shops, manning companies, and vendors etc. The industry exhibits the characteristics of commoditization driven by price. As the industry is significantly affected by the chartering market, I will herein focus on the chartering market and its movements, in order to better understand the industry. The structure of the market creates recurring cycles and instability. Also, the key elements affecting this market are highly interrelated. Characteristically, long delays of these key elements make the market more uncertain and more volatile. The purpose of this thesis is to study the dynamic of the oil tanker industry, in particular chartering market, using system dynamics methodology. A simulation model will illuminate the following:* Driving forces on the commoditized industry, Nature of the dynamics and structural behaviorsm, Effects of key elements on freight rates

Subramaniam, Kumaresan. "Human reliability assessment in oil tanker operations." Thesis, Liverpool John Moores University, 2010. http://researchonline.ljmu.ac.uk/5968/.

Full text

Abstract:

This research is carried out to improve Human Reliability Analysis (HRA) in oil tanker operations in general, to extend and enhance in specific Cognitive Reliability and Error Analysis Method (CREAM), with the aim of reducing human error and thus subsequently preventing oil tanker spills. It is concentrated on oil tanker operations to address the limitation of availability of human reliability data in the maritime domain. The continual occurrence of oil tanker spills, which was substantiated with analysis of historical data of oil tanker incidents/accidents from 1970 to 2008, provides a judicious reason to conduct this research. The critical review of Formal Safety Assessment (FSA) and HRA results in the development of a conceptual framework of HRA facilitating FSA and incorporating Human Organisational Factors (HOF), which addresses the shortcomings of the generic HRA and FSA methodologies that exist independently in the management of oil tankers to prevent oil spills. The CREAM is reviewed due to its prominent use in identifying the root causes of human error. However, its inability of providing solutions to an incident/accident investigation and robust quantification of human reliability features stimulates the development of an advanced CREAM and a human reliability quantification model using a combined Analytic Hierarchical Process (AHP) and fuzzy logic approach in this research. In addition to facilitating identification of the root causes of human error, the advanced CREAM also provides the solutions to a quantification model, which enables the development of HRA data in the maritime domain. Furthermore, lack of CREAM studies on relationships among Common Performance Conditions (CPCs) is addressed by proposing a Decision Making Trial and Evaluation Laboratory (DEMATEL) model, which allows for a comprehensive understanding of relationships and interdependencies among the CPCs. The model could also be used toappreciate and assimilate the relationships and interdependencies among human factor variables involved in other transportation systems and industrial fields. Finally, the research is concluded with an integrated AHP and fuzzy Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) model for determining the selection of an appropriate risk control option (RCO) while performing an incident/accident investigation by taking subjective judgments of decision makers into consideration. This research as a pioneer work in developing and applying advanced techniques to improve the generic CREAM in oil tanker operations establishes a foundation for future effort to improve the use of CREAM in other industries. The techniques developed can also be tailored to investigate and deal with an incident/accident effectively, resulting in the reduction of human error within the system management of any organisation.

Abstract:

Hur tillskriver vi moraliskt ansvar, och varför? Inom filosofin debatteras häftigt huruvida vi har fri vilja eller ej, och således ifrågasätts om vi kan tillskrivas moraliskt ansvar över huvud taget. Ett av argumenten som sägs hota den fria viljan är den omfattande situationistiska litteraturen, som verkar visa på att människors beteende påverkas mer av situationella faktorer än av personlighetsdrag. EH (Explanation Hypothesis) är en psykologisk hypotes som, förutom att redogöra för vardagliga moraliska bedömningar, kan reda ut filosofiska frågor såsom varför våra intuitioner kring moraliskt ansvar ter sig inkonsekventa. Denna studie testade EH experimentellt med en enkätstudie som dessutom undersökte folks intuitioner i moraliskt signifikanta situationer med kopplingar till den situationistiska litteraturen. Resultaten stärkte EH i enlighet med tidigare resultat, samt visade på att folks moraliska bedömningar inte påverkades av vetskapen om starka psykosociala fenomen som kan ha haft inverkan på agenternas beteenden. Implikationerna för den filosofiska debatten kring fri vilja och moraliskt ansvar, liksom begreppet determinism, diskuteras och förslag på fortsatt forskning läggs fram.
How do we attribute moral responsibility, and why? The notion of free will is heavily debated within philosophy, thus questioning whether we can truly be morally responsible for our actions. One of the arguments said to threaten the notion of free will is the vast collection of situationist literature that seem to show that human behavior is often more influenced by situational factors rather than personality traits. The Explanation Hypothesis (EH) is a psychological hypothesis that make general claims about everyday moral judgements, as well as accounting for philosophical issues such as the inconsistency of folk-intuitions on these issues. This study used surveys to test EH experimentally, also investigating folk-intuitions on moral responsibility in scenarios related to the situationist literature. The results support the hypothesis according to an earlier, similar study, as well as showing that the participants moral judgements were not influenced by being made aware of strong, psychosocial phenomena that seem to have had an impact on agents behaviors. The implications for the philosophical debate on free will and moral responsibility as well as the notion of determinism is discussed and further research is proposed.

Full text

Abstract:

Kommunikationen mellan lärare, elever och vårdnadshavare är en förutsättning för att arbetet på en skola ska fungera smidigt. Kommunikationen mellan lärare och vårdnadshavare anses som viktigt och det finns en rad hjälpmedel för att underlätta denna kommunikation. Jag har undersökt ett av dessa hjälpmedel – loggboken. Med loggbok menas här en typ av almanacka med utrymme för egna reflektioner och planering. Eleverna gör planering och utvärdering och en gång i veckan läser lärare och vårdnadshavare och gör eventuella kommentarer.

Syftet med den här studien var att undersöka några lärares, elevers och vårdnadshavares uppfattning om loggboken. Jag ställde upp frågeställningarna; Hur upplevs loggboken av några lärare, elever och vårdnadshavare? Hur används loggboken? Vilken kommunikativ funktion fyller loggboken? Jag vände mig till en 7-9-skola i Mellansverige som har viss erfarenhet av loggboksarbete. Jag intervjuade lärare, elever och vårdnadshavare, läste lokala styrdokument och gjorde observationer för att få en så bred syn som möjligt av arbetet och synen på loggboken.

Jag har funnit att loggboken används som ett kommunikationsmedel där den vandrar mellan elev, lärare och vårdnadshavare. Eleven gör en planering och utvärdering av sitt skolarbete i syfte att lära sig ta ansvar för sina studier. Därefter läser läraren och vårdnadshavaren och ger kommentarer. Detta leder till att läraren och vårdnadshavaren har en kommunikationskanal som de kan använda för att kommunicera med varandra om saker som rör eleven.

Uppfattningarna om loggboken varierade stort. De flesta lärare tyckte att arbetet med loggboken är bra eftersom en stor del av deras arbete med eleverna är att lära dem att lära. Genom att lära eleverna reflektera över sitt skolarbete ger de dem ett verktyg att senare i livet kunna reflektera över sitt lärande. Lärarna får dessutom chansen att kommunicera med vårdnadshavarna och även om de inte utnyttjar möjligheten fullt ut, så finns den där.

Eleverna förstår inte hela syftet med loggboken och deras uppfattningar är relativt negativa. De anser att den är stor och klumpig och jobbig att skriva i. Vårdnadshavarnas uppfattningar är postiva. De fick en insyn i skolarbetet som de inte hade annars och de förhöll sig positiva till den kommunikationsarena med lärarna som loggboken utgjorde.

Abstract:

Sammanfattning: Uppsatsens syfte har varit att undersöka hur slöjdlärare ser på den kreativa processen i slöjdämnet, den så kallade slöjdprocessen, vilken funktion den kan fylla och hur den kan lyftas fram i undervisningen. För att söka svar på dessa frågor har jag intervjuat fem verksamma slöjdlärare om deras syn på processen och vilka metoder de tillämpar i sin undervisning. En genomgång av litteratur i ämnet visar att elever har svårt att förstå vad som är syftet med slöjdundervisningen. Ämnet anses inte ha betydelse varken för framtida arbetsliv eller fortsatta studier. Jag menar i den här studien att slöjdämnet, förvaltat på rätt sätt, kan ha stor relevans för både framtida studier, arbetsliv och inte minst elevernas utvecklande av självkännedom. En av de viktigaste slutsatser jag drar utifrån studiens resultat är att den intellektuella delen i slöjdämnet behöver utvecklas. Samtal och reflektioner kring såväl skisser och slöjdföremål liksom elevers olika arbetsprocesser bör utgöra en betydande del av undervisningstiden.

While there is an increasing acceptance in academic literature about the importance of informal water delivery in cities around the developing world, public opinion is often divided. Many citizens see informal water vendors as businesses controlled by extortionary "mafias" and call for government regulation. This thesis explores whether government regulation is justified in the case of Bangalore, India where water issues have become increasingly pressing and informal water vendors, also known as the "water mafia," have grown in number and in influence. In particular, this thesis will explore whether private tankers display any form of anti-competitive behavior by addressing two questions: 1) Do private water tankers exhibit monopoly power, and 2) Do private water tanker prices vary depending on the characteristics of the customers they serve? Evidence collected in July-August 2014 and January 2015 indicates that tankers do not operate in an anti-competitive manner and that government intervention is not justified on these grounds. However, tankers do contribute to declining groundwater levels and government intervention on these grounds ought to be explored.

Abstract:

This thesis presents a new set of methods to assist the process of ship design for safety with particular reference to collision damage. The study has two principal objectives: " investigations into subdivision aspects of passenger ships to improve their overall survival index " investigations into the subdivision of oil tankers in order to improve the effectiveness against spillage in the event of collision damage. In order to investigate the ship subdivision aspect a damage stability model was needed. A pre-requisite for developing the damage stability software was a robust but flexible method to define the hull and the compartments of subdivision. B-splines have been a popular representationatl ool in computer aided design over the past three decades.T his method, though more complex than other spline techniques such as cubic splines, was adopted with a fourth order basis function in this work. A complete set of spline manipulation libraries and associated numerical solvers were developed for this purpose. In addition to this, a method to define the intersection between the hull and the waterplane in the form of a closed B-spline curve for any given orientation of the vessel in terms of -heel, trim and draught was developed to aid the damage stability calculations. Though the earlier regulations stipulate fixed trim assessments to ease the computational process, it is clearly unsatisfactory and research has confirmed this to be a flawed approach. Free trim calculations on the other hand require an iterative and time consuming process to arrive at the equilibrium trim position for each heel angle. Pawlowski proposed a new method for the stability calculations of a freely floating rig when the unit is arbitrarily orientated to the wind direction. It uses the Euler theorem on the properties of equivolume waterplanes to arrive non-iteratively at the new inclined position. This theory was adapted for use in damage stability calculations and was numerically tested and proved to be sound. Damage stability calculations, though combinatorially large, are also inherently parallel. Parallel Virtual Machines (PVM) is a Message Passing Interface (MPI) developed jointly by ORNL, University of Tennessee, Carnegie Mellon University and the Pittsburgh Supercomputing centre. PVM enables a "virtual configuration" so that a collection of serial, parallel and vector processing machines appear as one large distributed memory computer. PVM was compared with another MPI called Network Linda where the advantage of PVM's user controlled message passing was demonstratedP. VM was used to implement the MJMD Distributed Memory paradigm to exploit this inherent parallelism in damage stability calculations and to obtain speedups. A systematic exploration of the search space for this design problem involves the generation of a large number of internal subdivision configurations. This, coupled with the fact that the design space was multimodal in nature made it suitable to the application of a class of heuristic search algorithms called Genetic Algorithms (GA). A brief description of the mechanisms behind GA is presented along with their mathematical basis in the form of two theorems: the schema theorem and the building block hypothesis. Various techniques for solving constrained optimisation problems with GA was explored. The penalty function method was found to be the most suitable and was finally adopted. The above techniques were applied to the optimisation. of the internal subdivision of passenger ships and cargo ships, oil tankers in particular. For passenger ships, the nature of the 's'-factor formulation on the local index was shown. The multimodal nature of the subdivision problem was highlighted and a GA was used to investigate the optimal subdivision characteristics of the vessel. The 's' factor formulation for cargo ship rules is different to that described by the A. 265 set of regulations for passenger vessels. In addition, the cargo ship rules describe a factor V which accounts for the probabilities of vertical extents of damages. However this formulation does not assign any credit for horizontal subdivision below the waterline. Data on vertical extents and vertical location of damages for cargo ships was collected and analysed in earlier studies done at Newcastle University. This data was used to develop a probability function akin to that developed for the longitudinal extent and longitudinal location so as to give credit for any horizontal subdivisions. The principal objective of this part of the study was to explore the search space for subdivision configurations that would minimize net oil outflow.

Abstract:

Le transport sous contrat d'affrètement est pour un certain nombre de raisons qui seront examinées au cours de cette recherche (charges, indemnisation des dommages, pollutions, assurances etc.) le mode de transport le plus adopté pour le pétrole. Cette étude a pour objectif d’analyser le régime de responsabilité des parties contractantes dans le transport des produits par les navires pétroliers. De cibler corollairement l’âme du contrat qui est la question de la liberté contractuelle encadrée par les chartes parties proprement pétrolières. De déterminer le périmètre d'intervention des différents acteurs qui ont capacité à négocier dans le secteur du transport - ce qui implique d'abord de les connaitre. Aujourd’hui le marché de l'affrètement pourrait d'avantage être qualifié comme un commerce sous sa forme d'échange des informations. La clé du succès est ici, d’avoir accès aux informations correctes à un moment donné. Les analyses développées dans cette recherche montrent à l'évidence que la nature du marché du fret pétrolier n'est pas établie de manière unilatérale mais qu’elle résulte de plusieurs facteurs évoqués tout au long cette étude. La liberté des contractants est définie par les différents chartes parties. Ces chartes sont des modèles imposés par Ies compagnies. Il apparaît souhaitable qu'elle évolue vers un "multilatéralisme'
The transport under chartering agreement is for a number of reasons, which will be examined during this research, the most popular mode of transport for oil. The aim of this study is to analyse the liability regime of the contracting parties in the transport of products by oil tankers. It is also necessary to find out the freedom of contract framed by the chartered parties properly petrol. To determine the scope of intervention of various actors who have the capacity to negociate in the transport sector - which implies first to know them. Today the charter market could be better qualified as a trade in the form of information exhange. The key to success is here, to have access to the correct information at a relevant and good time. Analyses developed in this reseach show obviously that the nature of the market of the oil freight is not established in a unilaleral way but that it resulted from several factors evoked throughout this study. The freedom of the contracting parties is defined by various charter party. These charter parties and models been imperative by the companies. It sems desirable that it evolves towards a "multilateralism"

Abstract:

Battletank crew must perform many diverse tasks during a normal mission: Crewmembers have to navigate, communicate, control on-board systems, and engage with the enemy, to mention a few. As human processing capacity is limited, the crewmembers will find themselves in situations where task requirements, due to the number of tasks and task complexity, exceed their mental capacity. The stress that results from mental overload has documented quantitative and qualitative effects on performance; effects that could lead to mission failure.

This thesis describes a simulation of tankcrew during a mission where mental workload is a key factor to the outcome of mission performance. The thesis work has given rise to a number of results. First, conceptual models have been developed of the tank crewmembers. Mental workload is represented in these models as a behavior moderator, which can be manipulated to demonstrate and predict behavioral effects. Second, cognitive models of the tank crewmembers are implemented as Soar agents, which interact with tanks in a 3D simulated battlefield. The empirical data underlying these models was collected from experiments with tankcrew, and involved first hand observations and task analyses. Afterwards, the model’s behavior was verified against an a priori established behavioral pattern and successfully face validated with two subject matter experts.

Abstract:

Ett förändrat klimat kan komma att utsätta samhället för en rad olika påfrestningar, vilket förväntas ställa ökade krav på den fysiska planeringen av samhället. Detta examensarbete innefattar en studie vars syfte är att ta reda på hur tjänstemän som arbetar med fysisk planering på kommunal nivå upplever ansvarsförhållandet, liksom det praktiska arbetet med att anpassa samhällelig bebyggelse till ett förändrat klimat. Studien syftar också till att ge svar på den mer övergripande frågan om huruvida fysisk planering är ett lämpligt verktyg att använda för att anpassa samhällelig bebyggelse till de situationer som kan tänkas uppträda i ett förändrat klimat. Studiens genomförande grundas på kvalitativa intervjuer med tjänstemän som arbetar med fysisk planering i Helsingborgs stad, Kristianstads kommun, Landskrona kommun och Vellinge kommun samt en dokumentstudie av ovanstående kommuners översiktsplaner. Resultaten från studien visar bland annat att fysisk planering är ett lämpligt verktyg att använda för att anpassa samhällelig bebyggelse till ett förändrat klimat om klimathänsyn integreras i planeringen. För att arbetet med att integrera klimathänsyn ska underlättas föreslås det att man på statsmaktsnivå bland annat preciserar ansvarsfördelningen mellan kommunerna och de övrigt berörda myndigheterna, reder ut ansvarsförhållandet vad gäller kommunernas juridiska och ekonomiska ansvar samt utser en myndighet på central nivå som utarbetar riktlinjer för hur anpassningen till ett förändrat klimat ska ske.
A changing climate will affect and bring many consequences to society. The purpose of this thesis is to examine and evaluate how employees and officials in municipal planning organisations view climate change, understand their ideas about how municipal planning can continue in light of the emerging reality of climate change, and the division of responsibilities between the local and the national level. The aim of this study is also to find out if the present system of spatial planning work will be able to meet the challenges to adapt the municipalities and their infrastructure to unforeseen situations that may occur due to climate change. The study is based on qualitative interviews made with officials working with spatial planning in four different communities: Helsingborg, Kristianstad, Landskrona and Vellinge. Furthermore a study of each community’s spatial planning in relation to climate change issues was conducted. The result of this study shows that spatial planning could be a suitable instrument to use for adjusting the municipal planning process with regard to climate change, provided that climate concerns are integrated in the planning process. To simplify integration of climate issues we suggest that the Swedish national authorities should address and clarify the assignment of responsibilities between local authorities and other concerned authorities when it comes to climate change. It is also important that the responsibilities between the local authorities from both a legal and a financial point of view be investigated further. We suggest the need for the creation of a new government agency, which could responsible for coordinating all the above work so that municipalities could more effectively work on the issues of climate change in the spatial planning process.

Abstract:

Corporate Social Responsibility (CSR), det vill säga företags samhälleliga ansvar, har diskuterats under flera decennier. Trots det råder det fortfarande en tvetydighet kring vad det sociala ansvarstagandet egentligen innebär. Samtidigt har CSR har institutionaliserats som organisationskoncept och kommuniceras externt i organisationers strävan efter legitimitet. Det finns dock flera institutionella faktorer som kan inverka på organisationers benägenhet att agera ansvarsfullt, såsom etablerade lagar, regler, finansiella resurser och normativa uppmaningar i organisationers omgivning. Föreliggande studie syftar till att undersöka hur ett ledande företag inom färgtillverkningsindustrin uppfattar CSR och hur konceptet tar sig i uttryck i den dagliga verksamheten. Därtill syftar studien till att ge förklaringar till hur fallföretagets hållbarhetsarbete kan förstås i relation till färgtillverkningsbranschens omgivning, samt bakomliggande motiv till att arbeta med CSR. Studien nyttjar nyinstitutionell teori som teoretisk referensram tillsammans med institutionella faktorer som antas ha inflytande på viljan att arbeta med socialt ansvarstagande, samt olika former av organisatorisk legitimitet. Med hjälp av ett kvalitativt angreppssätt i form av intervjuer och textanalys utforskas hur CSR-konceptet uppfattas och tar sig i uttryck hos en framstående aktör inom färgtillverkningsindustrin. Studiens centrala resultat visar på att fallföretaget tycks använda CSR som ett legitimerande verktyg genom att externt kommunicera hållbarhet vilket främst uttrycks genom ökad miljöhänsyn i den dagliga verksamheten. Vidare visar studien på att färgtillverkningsindustrin anpassar sig till en teknisk och en institutionell omvärld genom anpassning till såväl lagar, regler, konkurrenter, kunder samt rådande normer och värderingar i samhället. Resultatet visade emellertid ett starkare beroendeförhållande till en teknisk omvärld mot bakgrund av kostnadseffektiviseringar för att därigenom nå lönsamhet. CSR-arbete tycks således i första hand implementeras mot bakgrund av ekonomiska och ekologiska drivkrafter.

Abstract:

Platform-ship collisions are fortunately rare events, but as the development of the offshore and oil industry and the gradually frequently used offloading operation, accidents become more and more frequent. The consequences of collisions are always severe, which includes loss of life, property and environmental damage. Thus It is important to predict the outcome of collision scenarios and assess the damage that may happen to the platform as well as the shuttle tanker.Collisions are always analyzed by means of the principle of the principle of energy conservation. Initial kinetic energy is dissipated by the two contact bodies as strain energy and in viscous force generation. There is also energy remained as the kinetic energy after the impact for both the striking and struck bodies, both for translational and rotational degrees of freedom. The external mechanics of the collision is easily evaluated, but the strain energy absorption can be rather difficult to evaluate in a correct way.In this thesis, A Samsung shuttle tanker and the Sevan SSP300 platform are analyzed as the striking and struck bodies, respectively. Structural configurations are described for both structures. Different impact scenarios are then discussed in the report, some of which are chosen to analyze in the thesis work. Non Linear Finite Element Analysis (NLFEA) model of the SSP300 platform is created. The shuttle tanker model is an exist one. One-sixth of the platform is modeled in detail with the correct stiffeners and other details, while for the other part, only the outer shell and the main bulkheads are modeled. For the tanker, adjustments are made in order to increase the calculation efficiency. Only the bow is remained in details. For the hull, only the outer shell is remained. For both structural models, adjustments are made to obtain the correct mass, added mass and inertial. Both models have a user defined material with the fracture criterion included. Integrated analysis is mainly performed. Then the integrated analysis is split into internal mechanics and external mechanics. Among these, integrated analysis and internal mechanics analysis are performed with finite element method, using the explicit NLFEA solver LS-DYNA. For the collision scenarios, only bow impact with different headings is considered. Two different impact velocities are chosen in both head on collision and collision with the glancing angle of 30 degrees. Energy absorption and force-displacement relationship can be obtained. Damage on the platform is also evaluated. Internal mechanics are then analyzed by changing the boundary condition and making the impact velocity constant. The purpose is to evaluate the damage with internal mechanics and then compare it with the results from integrated analysis. Liu’s method, which is based on Stronge theory, is mainly used in external mechanics as a simplified method. Herein a Matlab program is established to calculate the energy dissipation and the velocity after the impact. Two other simplified methods are utilized to calculate the dissipated energy and then compare them with the results from NLFEA analysis. One is from the DNV-RP-C204 and the other one is from T.de Jonge&L.laukeland’s report. The latter one is an optimized method compared to the one from DNV rules, which includes the effect of roll motion. Results from the simplified methods and NLFEA method show good correlation. All the simplified methods overestimate the absorbed energy, which is conservative. Among these, Liu’s method gives the best correlation with the NLFEA method. Two additional jobs are conducted in the end. Only the energy dissipation is analyzed in this section. One is changing the loading conditions of the two bodies. The energy dissipation becomes smaller after changing. The other one is changing the friction coefficient. The energy dissipated by the tanker is smaller, while by the platform is larger. But from the overall view, the energy does not show big difference with friction coefficient 0.15 and 0.4.

Abstract:

It is well understood that the spilled oil from damaged oil tankers poses a severe threat to the marine environment. Although great efforts have been devoted to studying the oil spilling from damaged oil tankers, especially double hull tanks (DHTs), the majority is subjected to an ideal condition (e.g., fixed tanks in still water; simple damage conditions) and adopts hydrostatic theories or quasi-steady models with over-simplified assumptions on data analysis or analytical prediction. These conditions or assumptions may not stand in the complex dynamic spilling process in the real spilling accident. This study brings a step further on the knowledge of oil spilling from a damaged tank by combining experimental and numerical investigations, with a focus on the dynamic spilling process from damaged oil tankers which is either fixed or subjected to motion, which have not been systematically investigated. In the experimental investigation, the submerged oil spilling from DHTs under different accidental scenarios including grounding and collision is studied. Two new sets of laboratory tests are carried out, where the damaged tank is fixed in still water. In the first set, the axial offset between the internal and the external holes on two hulls of the grounded DHT is considered to widen the scope of damage conditions which the tanker may suffer from during grounding accidents. Although all cases in this set are subjected to the same hydrostatic conditions, completely different dynamic spilling processes are observed. In the second set, the initial water thickness inside the ballast tank of the collided DHT is considered. This aims to represent the real scenarios that the external hull is generally damaged prior to the internal hull and, therefore the ballast space is partially filled by the water flowing from the surrounding environment before the internal hull is damaged. These experiments do not only advance the state of the art of the experimental study in this field, but also provide a reference for validating the numerical models developed in this study. Based on the experimental data, the correlation analysis for the discharge through the internal hole by using quasi-steady Bernoulli’s equation is presented, contributing to the development of an improved analytical model for predicting the oil spilling from damaged oil tankers. The numerical study is carried out using a numerical model developed in OpenFOAM framework, where the VOF is applied to deal with the air-oil-water multiphase flow. This model enables the users: (1) to consider air, oil and water three phases of fluid and their interaction with solid tanker hull using dynamic mesh technologies; (2) to model turbulence associated with the oil spilling process using various available turbulent models; and (3) to investigate the effects of the compressibility of the fluid. The oil spilling from damaged DHTs is simulated and validated by the experimental data. Intensive investigations are carried out to clarify uncertainties in existing numerical modelling of the oil spilling from damaged DHTs. These include (1) the associated turbulence behaviours and selecting an appropriate approach to turbulence modelling; (2) the role of fluid compressibility during the oil spilling; and (3) the effect of tank motion on the oil spilling process. For the turbulence modelling, various approaches to model the turbulence, including the large eddy simulation (LES), direct numerical simulation (DNS) and the Reynolds average Navier-Stokes equation (RANS) with different turbulence models are attempted. It is concluded that the oil spilling from DHTs is more sensitive to the turbulence modelling than that from SHTs. For DHT cases, the effective Reynolds number (Re) considering both oil outflow and water inflow is suggested to classify the significance of the turbulence and to correspondingly select the appropriate turbulence model. The investigation on the role of the air compressibility in the oil spilling from damaged DHTs reveals that the air compressibility may be considerable in a small temporal-spatial scale (e.g., jet-jet and jet-structure impact pressure), but plays an insignificant role in the macroscopic process of the oil spilling (e.g., spilling discharge and volume). In order to approach the spilling phenomena in the more realistic environment, a systematic numerical study is carried out to investigate the effect of the periodic ship motion on the oil spilling from the damaged tank. Different tank designs (i.e., SHTs and DHTs), accidental scenarios (i.e., grounding and collision) and tank motion parameters (i.e., types, frequencies and amplitude) are considered. The result indicates that the tank motion does not only cause a periodic oscillation of the oil/water flow through the broken hole, but also induces a second long-duration stage of spilling after a quasi-hydrostatic-equilibrium condition occurs, resulting in the more significant amount of spilled oil. By using both the experimental data and numerical results produced in this research, an improved prediction model for oil spilling from damaged DHTs in still is formulated. This model considers the case-dependent hydrodynamic interaction between the oil and water jet flows inside the ballast tank and its effect on the spilling process. The result using the improved model is compared with the numerical result indicating its superiority over the existing model.

Emerging technologies in CO₂ air capture, high temperature electrolysis, microchannel catalytic conversion, and Generation IV reactor plant systems have the potential to create a shipboard liquid fuel production system that will ease the burdened cost of supplying fuel to deployed naval ships and aircraft. Based upon historical data provided by the US Navy (USN), the tanker ship must supply 6,400 BBL/Day of fuel (JP-5) to accommodate the highest anticipated demand of a carrier strike group (CSG). Previous investigation suggested implementing shipboard a liquid fuel production system using commercially mature processes such as alkaline electrolysis, pressurized water reactors (PWRs), and methanol synthesis; however, more detailed analysis shows that such an approach is not practical. Although Fischer-Tropsch (FT) synthetic fuel production technology has traditionally been designed to accommodate large economies of scale, recent advances in modular, microchannel reactor (MCR) technology have to potential to facilitate a shipboard solution. Recent advances in high temperature co-electrolysis (HTCE) and high temperature steam electrolysis (HTSE) from solid oxide electrolytic cells (SOECs) have been even more promising. In addition to dramatically reducing the required equipment footprint, HTCE/HTSE produces the desired synthesis gas (syngas) feed at 75% of the power level required by conventional alkaline electrolysis (590 MWe vs. 789 MWe). After performing an assessment of various CO₂ feedstock sources, atmospheric CO₂ extraction using an air capture system appears the most promising option. However, it was determined that the current air capture system design requires improvement. In order to be feasible for shipboard use, it must be able to capture CO₂ in a system only 1/4 of the present size; and the current design must be modified to permit more effective operation in a humid, offshore environment. Although a PWR power plant is not the recommended option, it is feasible. Operating with a Rankine cycle, a PWR could power the recommended liquid fuel production plant with a 2,082 MWth reactor and 33% cycle efficiency. The recommended option uses a molten salt-cooled advanced high temperature reactor (AHTR) coupled to a supercritical carbon dioxide (S-CO₂) recompression cycle operating at 25.0 MPa and 670°C. This more advanced 1,456 MWth option has a 45% cycle efficiency, a 42% improvement over the PWR option. In terms of reactor power heat input to JP-5 combustion heat output, the AHTR is clearly superior to the PWR (31% vs. 22%). In order to be a viable concept, additional research and development is necessary to develop more compact CO₂ capture systems, resolve SOEC degradation issues, and determine a suitable material for the molten salt/S-CO₂ heat exchanger interface.

Abstract:

Från början hade vi ställt in oss på att vi ville hitta ett nytt sätt på hur man kan designa IT-relaterade produkter med ungdomars välmående och hälsa i tanke. Detta visade sig inte vara den lättaste uppgift två interaktionsdesigners, utan någon som helst bakgrund eller insyn om människors välmående, kunde tänka sig. Efter mycket efterforskning både i böcker och på Internet började vi förstå att vi inte var ensamma i vårt mål att motverka att stress uppstår i relation till dagens informations teknik. Flera andra forskare med bakgrund inom sjukdomar, rehabilitering och medicin hade varit aktiva inom fältet men bara ett fåtal interaktionsdesigners innan oss hade försökt sig på något liknande. Vi fick mycket inspiration från deras tidigare projekt och vi har försökt använda oss utav deras kunskaper och resultat. Våra kunskaper inom ämnet teknik och design visade sig inte vara särskilt användbara så vi fick komma på nya sätt att tänka på som de innan oss hade fått göra. Det här handlade om människor som lider av en sjukdom som är allmänt känd och kan i värsta fall leda till döden men som det, enligt oss, läggs för lite vikt på och aktörerna inom fältet var för få i förhållande till hur farlig sjukdomen är. I vår iver att börja på själva designen av den gestaltande produkten kom vi ibland på villospår eftersom vi var oförberedda på problem som kunde uppstå. Inspirerade från projekt såsom Brainball, Rewind och Virus, och efter en noggrann analys av vår förstudie fick vi flera vägar att välja bland och vi hoppas att vi valde rätt eftersom ämnet känns viktigt för oss. Sättet vår gestaltning är utformad på känns tillfredställande i förhållande till informationen vi fick fram efter analys av våra användarstudier. Vi hade inte marknaden som mål när vi skapade vår produkt utan försökte istället tillämpa vissa av Slow Design- och Flow filosofierna som vi kommit i kontakt med. Deras synsätt handlar mycket om att man som designer först och främst ska sätta användaren i fokus när man designar och sedan se till att man producerar. I dagens företag ägnas inte tillräckligt mycket tid till att skapa bra och användarvänliga produkter för slutanvändaren. Med vårt arbete hoppas vi kunna öppna upp vägen för andra designers som vill fortsätta forska om detta viktiga och intressanta ämne. Självklart lyckades vi inte göra just det vi hade satt upp som mål från början men vi båda är nöjda med resultatet ur ett perspektiv som interaktionsdesigners. Vårt koncept är inte på något sätt revolutionerande men vi tror på att folk kan komma att uppskatta det för själva enkelhetens skull. Keep it simple, keep it clean.
This essay will focus on the growing stress in our society in relationship to the increasing consumption of IT-related products. Stress is in out culture a well spread illness and we have tried to find the connection between people’s bad physical condition and the large escalation of information technology. The word stress can be defined as the reaction of maladjustment between the individual’s capabilities and the outer world’s demands and needs. We asked ourselves how extensive information technology contributes to stress in our society in our day of age. Present research shows that technology which is not user-friendly and rather difficult to manage contributes in large extent on work places to long term stress. In intent to obtain a greater knowledge of how stress exists and forms all around us, we made a survey which did not contradict earlier research results in the same subject. The survey itself discusses the relationship between stress, relaxation and the everyday usage of IT-products. The survey consisted of personal interviews that were performed in a, for the persons interviewed, natural environment – the school. The answers on our questions are divided in different categories and we have drawn some conclusions about when, how and why information technology stresses individuals in common life. Before we actually began with the survey itself, we had to understand deeper what stress is and the different stress theories that exist around the subject. The concept of Flow attempts to explain how one can use positive stress to enhance his own life. Today there are IT-products everywhere around us and many of these products are developed without actually taking time to consider people’s health in relation to them. Slow Design is on the contrary a design philosophy which implicates that products should be designed with the human in mind. With help from all our information and our surveys, our gestalt product became in some degree what we had planned from the beginning. The core in our original idea was to somehow integrate stress and IT.

Abstract:

Syftet med vår studie är att belysa utevistelsens pedagogiska roll i förskolans alla utomhusmiljöer och det medvetna förhållningssättets betydelse för verksamheten. Litteraturen utgår från forskares åsikter om utomhuspedagogik som kopplas till styrdokumenten. I undersökningen används intervjumetod. Intervjuer har gjorts med åtta förskollärare från olika förskolor med så lika förutsättningar som möjligt för utevistelse. Vi vill få en inblick i det medvetna pedagogiska förhållningssättets och helhetstänkandets betydelse vid utevistelsen på förskolan. I undersökningen framkom det att förskollärarna har liknande uppfattning om vad som är viktigt att barn utvecklar utomhus. Motoriken, naturupplevelser och frisk luft utgör viktiga inslag i utevistelsen. Det finns viktiga aspekter med de olika förmågorna förskollärarna nämner som utevistelsen har en positiv inverkan på. Många av förskollärarna belyser naturupplevelser eftersom naturen på så sätt upplevs i sin autentiska miljö. Vad barnen utvecklar i samband med de aktiviteter som förekommer stämmer inte alltid överens med det förskollärarna vill att barnen ska utveckla. Detta resultat synliggör det medvetna förhållningssättets betydelse, att det måste fungera från tanke till handling för att barnen ska kunna utvecklas i den riktning pedagogerna anser att de behöver. Den pedagogiska utevistelsen på förskolan är viktig eftersom barns olika utvecklingsområden stimuleras på ett sätt som enbart utevistelsen kan.

A operação de campos de petróleo em alto mar implica na transferência de óleo que acumula em Unidades Flutuantes de Produção, Armazenamento e Descarregamento (FPSOs em inglês) para terminais em terra. Uma frota de Petroleiros Dinamicamente Posicionados (DPTs em inglês), ou navios aliviadores, é utilizada para a transferência de óleo das plataformas flutuantes até os terminais terrestres, onde depois o petróleo é transportado em grandes petroleiros ou por dutos até as refinarias. O escalonamento de uma frota de navios aliviadores, que minimiza os custos operacionais e que atenda às restrições do sistema, consiste em um problema complexo. Este trabalho propõe uma formulação em Programação Linear Inteira Mista (MILP em inglês) que avança em relação à trabalhos anteriores pela contabilização de tempos de viagem variáveis entre plataformas e terminais terrestres. As viagens dos navios aliviadores são modeladas como caminhos em um grafo direcionado tendo o terminal terrestre, plataformas flutuantes e pontos de controle como nós, enquanto os arcos representam os possíveis movimentos e operações de carregamento/descarregamento dos navios aliviadores. Do ponto de vista econômico, a frota de navios aliviadores deve ser escalonada para maximizar a produção de petróleo nas plataformas flutuantes enquanto minimiza os custos gerados pelas viagens. A combinação da formulação MILP com um solver constitui uma ferramenta para auxiliar os engenheiros na tomada de decisões. Este problema pode ser resolvido diariamente utilizando a estratégia de rolling-horizon para responder a eventos inesperados. No capítulo 1 apresentamos o problema do Planejamento do Suprimento de Petróleo que envolve desde a produção de óleo e gás nas plataformas até o atendimento da demanda do mercado com os subprodutos beneficiados nas refinarias. O escalonamento de navios aliviadores constitui um subproblema da cadeia produtiva de petróleo e possui uma importância tática dentro do planejamento das operações. No capítulo 2 discutimos alguns conceitos importantes no campo da otimização. Primeiro definimos o que é otimização e o que é um modelo de otimização utilizando como exemplo o Problema da Mochila. Em seguida, apresentamos o conceito de Programação Inteira (IP) e Programação Linear Inteira Mista (MILP) e fazemos uma breve discussão sobre algoritmos para a solução de IPs e MILPs. Também introduzimos o conceito de relaxação e sua relevância na solução de problemas de otimização. Uma seção é dedicada para a introdução de conceitos relacionados com problemas de escalonamento e roteamento e por último apresentamos alguns métodos de otimização dinâmica como o rolling-horizon e relax-and-fix. No capítulo 3, apresentamos primeiro uma formulação prévia do problema que considera os tempos de viagem entre as plataformas e os terminais terrestres como fixos e em seguida, propomos uma nova formulação que considera os tempos de viagem variáveis. Uma revisão da literatura é feita com o intuito de relacionar o modelo proposto com outros trabalhos. O capítulo termina com resultados teóricos obtidos a partir do novo modelo. No capítulo 4 desenvolvemos a relaxação Lagrangeana do problema que origina o problema Dual Lagrangeano. Em seguida, apresentamos os algoritmos utilizados para a solução do problema dual e finalizamos o capítulo desenvolvendo a decomposição da função Dual Lagrangeana que quebra a função dual em diversas funções, uma para cada navio aliviador e plataforma, permitindo assim computação paralela. No Capítulo 5 definimos uma instância exemplo com campos de petróleo, terminais terrestres e navios aliviadores, no qual as análises computacionais são feitas. A primeira análise consiste em comparar os limites obtidos pela relaxação Lagrangeana e a relaxação linear do problema. Os métodos do subgradiente e de geração de restrições sob demanda foram utilizados para a solução do problema Dual Lagrangeano. Em seguida, comparamos a solução estática, onde o problema é resolvido para todo o horizonte de planejamento, com a solução dinâmica obtida utilizado as heurísticas de rolling-horizon e relax-and-fix. Estas em geral fornecem soluções sub-ótimas mas respondem de forma satisfatória às grandes instâncias e incertezas do problema. Fechando o capítulo, a estratégia de rolling-horizon é avaliada em um simulador que gera perturbações para variáveis do modelo. No capítulo 6 concluímos a dissertação com uma análise geral e contribuições do trabalho e propomos algumas direções para pesquisas futuras.

Abstract : The logistics of operating oil fields off the coast entails transferring oil that accumulates in Floating Production Storage and Offloading Units (FPSOs) to onshore terminals. A fleet of Dynamically Positioned Tankers (DPTs), or shuttle tankers, is deployed for transferring oil from the floating platforms to onshore terminals, where the oil is transported in large tanker ships or by pipelines to refineries. The scheduling of a fleet of shuttle tankers that minimizes the operating costs while satisfying the system constraints consists of a complex problem. To this end, this work proposes a formulation in Mixed-Integer Linear Programming (MILP) that advances previous works by accounting for variable time travel between floating platforms and the onshore terminal. The trips of the shuttle tankers are modeled as paths in a directed graph having the onshore terminal, floating platforms, and control points as nodes and arcs representing possible moves and offloading operations for the shuttle tankers. As a business case, the fleet of shuttle tankers should be scheduled to maximize oil production from the floating platforms while factoring in the transportation costs. The combination of the MILP formulation with an optimization solver constitutes a tool to aid operations engineers in making advised decisions. This formulation can be systematically solved daily in a rolling-horizon framework to respond to unanticipated events.
