Abstract (sommario):

With the Three Gorges reservoir built up, the water level rises sharply and the low construction water level in dry season does not exist. The relatively low water level is in draw-off period and building port faces long time of deep water level and precipitous fluctuation of water level in flood period. There are huge quantities under water. The construction period of low water level is short and the height of water level is up to 30 meters. Port construction is more difficult and complex at the Three Gorge reservoir region. This paper aims at these situations and puts forward the port constructing technique in deep water areas. It will provide guidance and reference in wharf construction.

Abstract (sommario):

With the continuous development of smart ports, the construction of port information systems has become the construction focus of the future development of such ports. However, the existing performance evaluation system for port information systems represents a research gap. It cannot effectively achieve specific improvement in the construction of information systems for port services and capabilities. In this paper, an evaluation index system was forged from the three perspectives of the operating level, management capability, and economic efficiency. As a first step, starting from the current situation of Beibu Gulf Port (Port B) construction, the three dimensions of the evaluation index system were determined using the scheme of literature review, questionnaire research, and fieldwork. Additionally, through adversarial interpretive structural modeling (AISM), it is concluded that the port loading and unloading operation capability and service level are the fundamental factors for measuring the construction performance of the container terminal operation system (CTOS). The results are used as input to construct an analytic network process (ANP) model to obtain the index weights. Finally, the gray clustering method (GCM) is introduced to construct a quantitative evaluation model to quantitatively evaluate the construction performance of the Port B CTOS. The quantitative benefits brought by the construction of the CTOS are finally verified. The scores of the corresponding dimensions of the port before and after the construction of the CTOS system in Beibu Gulf Port are obtained experimentally. The conclusion shows that the construction of CTOS makes the port operating level module improve the most, from 40.023 to 70.733 points; at the same time, it is found that two aspects, i.e., green security and economic benefits, in current construction are directions requiring further work in future port construction. Finally, a visualized quantitative analysis and evaluation method for the performance of smart port construction is proposed.

Abstract (sommario):

Ports are not only an important driving force for the growth of the world economy but also the main energy-consuming unit and pollution source in the world. Under the new global energy crisis and environmental deterioration situation, the international port community has put forward the concept of green port development. As a guide, the government’s environmental regulation strategy can directly affect green port construction through market incentive or command control means and can also indirectly affect green port construction through the intermediary role of green innovation, industrial agglomeration and green logistics. Considering the strategic choices of the government, port enterprises and transportation enterprises, this paper constructs a tripartite evolutionary game model and considers whether the government carrying out environmental regulation is affected by the fine income and management cost, whether the willingness of port enterprises to carry out green port construction is determined by the extra construction cost and income and whether transportation enterprises choose green port logistics transportation depending on the extra income they receive. In the process of tripartite cooperation, the government’s environmental regulation, port enterprises’ green port construction and transportation enterprises’ choice of the green port logistics transportation mode constitute the most ideal strategy combination. Finally, the paper puts forward some suggestions for the strategy selection of the three parties in order to promote the realization of the ideal strategy combination and provide a theoretical reference for the construction of green ports.

Abstract (sommario):

The application of analytical hierarchy process (AHP) to the risk analysis of port construction project was investigated. Firstly, the happening probabilities of various risk factors during port construction were calculated. Secondly, the aftereffects of the risks were concluded by consulting the experts. Thirdly, the weight of each risk factor was obtained by AHP. Finally, the total risk of port construction project could be evaluated by fuzzy comprehensive evaluation. This risk analysis method was applied to evaluate the total risk of a real port construction project, and the exemplification verified its feasibility.

Abstract (sommario):

In the process of port logistics outsourcing, because there are different throughput requirements of port logistics, there are inherent risks in logistics outsourcing companies, it cannot ensure the reasonableness of port logistics outsourcing. In this paper, a rationality analysis model of port trade logistics outsourcing based on analytic hierarchy process is proposed. Using the Analytic Hierarchy Process get different specification weights, and sort the importance degree of port trade logistics outsourcing risk, to create the hierarchical structure model of port trade logistics hierarchical assessment. The operating performance, cost performance and service performance and so on of port trade enterprises are made overall decomposition and analysis. Through the assignment make comparison operation to obtain the proportion of different schemes which should be accounted for in the overall target. Using analytic network process and customer rationality index model make accurate analysis of the rationality of hierarchical logistics outsourcing in port trade. The experimental results show that the coverage rate of logistics outsourcing, value of port trade and the effectiveness of the model under this kind of model is superior to the traditional model, and it achieves satisfactory results.

Abstract (sommario):

Floating port is a barge made of rectangular steel or concrete that can float to adjust the water lavel. Barge is a cargo ship type do not have a propulsion system. So, design of floating port preferably aqual to ship design. There are 3 types of barge construction system, that are longitudinal system, transversal system and mixed construction. To get the optimal design of floating port, comparison of design based on the construction system is needed. Case study in this research ia a Tideng Pale-KTT floating port. Deformation and stress analysis using FEA method on 2 models of construction system, that are transversal and longitudinal. Based on results, both of construction system produce a good strength value. However, there are some construction component which does not match the placement of the construction system. Results of construction costs have 5,51% deviation, longitudinal sytem is more expensive. So, produce the hypotheses to do a combination for both of construction systems.

Abstract (sommario):

La présente thèse porte sur le développement du port de Shanghai de 1843 à 1912, en se concentrant sur l’histoire des entreprises étrangères installées à Shanghai pendant cette période. À une époque où la Chine promeut son Initiative de la Ceinture et la Route, visant à étendre son influence mondiale en aidant les pays participants à développer leurs infrastructures publiques, notamment portuaires, il est intéressant de réétudier l’histoire du développement du port de Shanghai durant la période concessionnaire. Les concessions étrangères de Shanghai et les entreprises privées établies sur place entre 1843 et 1912 ont joué un rôle essentiel dans la construction du port de cette ville, qui est devenu par la suite un modèle de développement pour les autres villes portuaires chinoises. La ville de Shanghai telle que nous la connaissons aujourd’hui trouve ses fondations durant cette période. Cette thèse essaie de démontrer en quoi les compétitions commerciales des entreprises étrangères présentes à Shanghai ont été le moteur du développement de son port. Elle explore le contexte historique, les étapes clés de la construction du port, l'aménagement et la gestion, ainsi que l'impérialisme occidental et l'émergence d'une conscience nationale chinoise
This thesis focuses on the development of the Shanghai port from 1843 to 1912, with a particular emphasis on the history of foreign enterprises established in Shanghai during this period. At a time when China is promoting its Belt and Road Initiative, aimed at expanding its global influence by assisting participating countries in developing their public infrastructure, including ports, it is interesting to reexamine the history of the development of the Shanghai port during the concession period. The foreign concessions in Shanghai and the private enterprises established there between 1843 and 1912 played a crucial role in the construction of the port, which later became a development model for other Chinese port cities. The city of Shanghai as we know it today has its foundations in this period. This thesis seeks to demonstrate how the commercial competition among foreign enterprises in Shanghai drove the development of its port. It explores the historical context, key stages of port construction, planning and management, as well as Western imperialism and the emergence of Chinese national consciousness

Abstract (sommario):

Construction management competencies are essential to realise sound practices among and to realise optimum performance by, inter alia, emerging civil engineering contractors. Such competencies enable a clear focus on the business of construction and the management of projects, with increased efficiency and reduced costs as a benefit. The objective of the MSc (Built Environment) treatise study were to determine the current practices and performance of emerging civil engineering construction contractors operating in the Nelson Mandela Bay Metropole. The descriptive method was adopted in the empirical study. The salient findings of the study are: most of the emerging civil engineering construction contracting organisations lack construction management competencies; construction resources are inappropriately managed leading to construction failures; most of the emerging civil engineering construction contracting organisations lack adequate supervision resulting to poor workmanship; there is a shortage of skilled labour amongst emerging civil engineering construction contractors; procurement processes are inappropriate leading to under capacitated emerging civil engineering construction contracting organisations being awarded contracts; most emerging civil engineering construction contracting organisations lack the requisite aptitude for construction; there is a lack of capacity at all management levels of emerging civil engineering construction organisations in managing the business of construction and that of projects; the nine functions of organisations are not comprehensively represented, and self-ratings indicate inadequacy relative to the management function of control, and relative to certain activities of the organising function. Conclusions include that emerging civil engineering construction contracting organisations need to be comprised of technical teams that possess adequate competencies and that use the construction technology to its full use enabling their organisations to stay abreast of their competitors. Recommendations that can contribute towards improving the status quo include: formal civil engineering and construction management education, resources must be present and training should be promoted throughout the industry at all levels of management to ensure proper supervision and correct use of adequately trained labour, skilled or semi-skilled, incapacitated emerging civil engineering construction contractors should be awarded contracts through appropriately and structured procurement procedures, adequate aptitude in construction should be promoted and enhanced in order to realise conceptualisation and visualisation capabilities, comply with legislation, maintain records and communicate using state of the art technology, optimally manage the finances, have the requisite resources and undertake the work efficiently, interact with the respective publics, and market the organisation to ensure sustainability thereof.

Abstract (sommario):

The design and construction of vertical caisson breakwaters on soft soils represents a significant challenge for the engineering of marine structures. Past experience reveals that this type of structures is sometimes prone to failure or to undergo excessive settlements. Cyclic loading due to storm wave action adds an addtional degree of complexity. This Thesis present the performance of a wide-ranging set of geotechnical activities to address the key issues of stability, large caisson displacements and cyclic loading effects in the context of the construction of vertical breakwaters. They include site investigation operations (involving laboratory tests, in situ tests and field tests), constitutive models for soft clays (under static and cyclic conditions), instrumentation and monitoring systems, numerical modelling of the breakwater during and after construction and the evaluation of stability under static and cyclic loads. The construction and performance of a vertical breakwater built on the soft soils of the Port of Barcelona provides the focal point to integrate the description of those activities in a joint and structured manner. After reviewing the main aspects associated with the construction and performance of vertical breakwaters, the behaviour of the soft foundation soil is examined. Laboratory tests, in situ tests and a large scale instrumented preload test are considered. Particular attention is paid to undrained shear strength, small strain stiffness, compressibility characteristics and cyclic loading effects. Soil behaviour is then modelled by a range of different constitutive laws of different degrees of complexity. The proper representation of strength anisotropy, long-term creep and cyclic behaviour is explicitly addressed. An extensive monitoring system for the measurement of pore pressures and soil movements has been installed before construction and, following the loss of a number of sensors, after caisson emplacement as well. A novel feature of the instrumentation was the installation of sensors on the front and on the base of the caisson to measure the hydraulic response to the impact of sea waves. The monitoring data has provided the necessary information to achieve a sounder knowledge of the behaviour of the breakwater at different stages of construction and post-construction, including the response under storm loading. Numerical analyses have been carried out towards achieving a better understanding of the breakwater behaviour during construction, post-construction and under cyclic loads. The interplay between monitoring observations, construction history and simulation results is highlighted. Special attention has been given to the evaluation of stability during construction and post-construction. Whenever relevant, the observations provided by the monitoring system are incorporated in the evaluation; the measurement of the evolution of pore pressures has proved important to ensure the safety of the caisson during construction. Breakwater stability under cyclic loading has also been evaluated using both simplified and advanced methods. This ensemble of works performed in the context of a well-documented case history should prove of benefit for the design and construction of similar structures founded on soft ground.
El diseño y construcción de rompeolas de cajones verticales en suelos blandos representa un desafío importante para la ingeniería de estructuras marinas. La experiencia pasada revela que este tipo de estructuras en ocasiones son propensas a fallar o sufrir asentamientos excesivos. La carga cíclica debido a la acción de las olas de tormenta agrega un grado adicional de complejidad. Esta tesis presenta la realización de un amplio conjunto de actividades geotécnicas para abordar los problemas clave de estabilidad, grandes desplazamientos de cajones y efectos de cargas cíclicas en el contexto de la construcción de rompeolas verticales. Entre las que se incluyen operaciones de investigación del sitio (que incluyen pruebas de laboratorio, pruebas in situ y pruebas de campo), modelos constitutivos para arcillas blandas (en condiciones estáticas y cíclicas), sistemas de instrumentación y monitoreo, modelado numérico del rompeolas durante y después de la construcción y la evaluación de la estabilidad bajo cargas estáticas y cíclicas. La construcción y ejecución de un rompeolas vertical construido sobre los suelos blandos del Puerto de Barcelona proporciona el punto central para integrar la descripción de esas actividades de forma conjunta y estructurada. Luego de revisar los principales aspectos asociados con la construcción y desempeño de rompeolas verticales, se examina el comportamiento del suelo blando de cimentación. Se consideran pruebas de laboratorio, pruebas in situ y una prueba de precarga instrumentada a gran escala. Se presta especial atención a la resistencia al corte no drenado, la rigidez en pequeñas deformaciones, las características de compresibilidad y los efectos de carga cíclica. Luego, el comportamiento del suelo se modela mediante una gama de diferentes leyes constitutivas de diferentes grados de complejidad. Se aborda explícitamente la representación adecuada de la anisotropía de la resistencia, la fluencia a largo plazo y el comportamiento cíclico. Se ha instalado un extenso sistema de monitoreo antes de la construcción, para la medición de presiones de poros y movimientos del suelo y, luego tras la pérdida de varios sensores, después del emplazamiento de los cajones. Una característica novedosa de la instrumentación fue la instalación de sensores en el frente y en la base del cajón para medir la respuesta hidráulica al impacto de las olas del mar. Los datos de seguimiento han proporcionado la información necesaria para lograr un conocimiento más sólido del comportamiento de los rompeolas en diferentes etapas de construcción y posconstrucción, incluida la respuesta bajo carga de tormenta. Se han realizado análisis numéricos para lograr una mejor comprensión del comportamiento del rompeolas durante la construcción, posconstrucción y bajo cargas cíclicas. Se destaca la interacción entre las mediciones realizadas, el historial de construcción y los resultados de la simulación. Se ha prestado especial atención a la evaluación de la estabilidad durante la construcción y posconstrucción. Siempre que sea relevante, las observaciones proporcionadas por el sistema de seguimiento se incorporan a la evaluación; La medición de la evolución de las presiones intersticiales ha demostrado ser importante para garantizar la seguridad del cajón durante la construcción. La estabilidad del rompeolas bajo cargas cíclicas también se ha evaluado utilizando métodos tanto simplificados como avanzados. Este conjunto de trabajos realizados en el contexto de un caso de estudio bien documentada debería resultar beneficioso para el diseño y la construcción de estructuras similares cimentadas en terreno blando.

Abstract (sommario):

Au début du XIXe siècle, la marine connaît une mutation technique accélérée. Le « vieux port » aux origines médiévales de la Rochelle ne répond plus aux besoins de la navigation, ce qui donne lieu au creusement d’un bassin intérieur effectif en 1808. Cet équipement s’avère vite insuffisant et au milieu du siècle, la construction d’un second bassin hors les murs s’impose et voit le quartier de la Ville-en-Bois se développer à proximité. Rapidement, à son tour, dans les années 1850-1860, ce nouveau bassin ne répond plus aux exigences maritimes modernes. La construction d’un troisième bassin à flot en eau profonde est alors envisagée pour la première fois. La question du lieu se pose. La réponse vient de l’ingénieur hydrographe Bouquet de la Grye, qui, après avoir étudié différentes possibilités de la rade, propose en 1876 un lieu à 5 km à l’ouest de la ville, ce sera la création du port en eau profonde de La Pallice. La venue, en 1878, du ministre des travaux publics Freycinet entérine ce grand projet devenu national. Les travaux débutent en 1880 jusqu’au 19 août 1890, date de l’inauguration par le président Sadi Carnot. Le 5 juin 1891, l’établissement portuaire est ouvert à la navigation et le trafic se développe selon une progression constante. La Première Guerre mondiale met en lumière les avantages de La Pallice et son rôle important dans la défense nationale, mais le port présenté comme moderne en 1890 devient bientôt exigu pour recevoir des navires de plus en plus grands. La construction d'un môle d'escale en eau profonde est adoptée en 1923, pour être en partie opérationnel avant la Seconde Guerre mondiale. Cette thèse qui relève de l’histoire urbaine s'attache également à démontrer en quoi la création du port de la Pallice a permis à La Rochelle de renouer avec son grand destin maritime en relançant son économie marchande
At the beginning of the 19 th century, the navy underwent an accelerated technical change. The "old port" with medieval origins of La Rochelle no longer meets the needs of navigation, which gives rise to the digging of an effective interior basin in 1808. This equipment quickly proves insufficient and in the middle of the century, the construction of a second basin outside the walls was essential and saw the Ville-en-Bois district develop nearby. Quickly, in turn, in the years 1850-1860, this new basin no longer met modern maritime requirements. The construction of a third wet dock in deep water was then considered for the first time. The question of location arises. The answer comes from the hydrographer engineer Bouquet de la Grye who, after having studied the various possibilities of the bay, proposed in 1876 a place 5 km west of the city, with would be the creation of the deep water port of La Pallice. The visit of the Minister of Public Works, Freycinet, in 1878, endorsed this major project which had become national in scope. Work began in 1880 until August 19, 1890, the date of inauguration by President Sadi Carnot. On June 5, 1891, the port establishment was opened to navigation, and traffic grew steadily. The First World War highlights the advantages of La Pallice and its important role in national defence, but the port presented as modern in 1890 soon becomes cramped to receive increasingly large ships. The construction of a deep-water stopover mole was adopted in 1923, to be partly operational before the Second World War. This thesis, which is part of urban history, also aims to demonstrate how the creation of the port of La Pallice has enabled La Rochelle to renew its great maritime destiny by reviving its marchant economy

Abstract (sommario):

The objective of this treatise study was to determine the leading causes which limit the development of SMME contractors, to ascertain the accessibility of SMME incubators available to support SMME development and to identify the cause of poor management performance by SMME contractors based in the Nelson Mandela Bay Metropolitan Municipality. A qualitative method was adopted for this study. The primary data was collected using a structured interview guide which incorporated the sub problems and the research questions. The salient findings of this study are: SMME contractors are unaware of the available business information and government support programmes designed to assist them; SMME contractors do not receive capital from banks when they don‟t have collateral; Desperation to secure projects among SMME contractors is the leading cause for under-pricing; SMME contractors are still paid later than the 30 day period for completed work; SMME owners who had started their construction companies lacked training and do not have the relevant experience and knowledge required to manage a construction company. In summary the study concluded that SMME who have access to capital have high growth prospects than those that have not. Accessibility to information and awareness of available opportunities remains significant for the growth of SMMEs. Construction related knowledge and training for SMME owners contributes vastly to the success of SMME companies. The study recommended that; Government needs to promote the accessibility of SMME incubators and ensure institutions designed to assist SMMEs with finance are accessible; The effectiveness of current development programs for small enterprises and skills development programs should be reviewed; MMBM should setup a mentoring program to help train SMME contractors theoretically and practically; NMBM local government should promote women to own SMMEs in order to close the gap of inequality in the built environment; Banks must work with government institutions to ensure that they are able to fund SMMEs.

Abstract (sommario):

La circulation des flux de matières et d’énergie reflète aussi bien le fonctionnement de la biosphère que celui des sociétés humaines. L’écologie industrielle, dans son approche territoriale, interpelle ces interactions socioécologiques au sein d’un espace géographique et participe ainsi à la définition et à la structuration de l’espace en territoire. Par une approche expérimentale déclinée sur les espaces portuaires, nous cherchons à rendre manifeste, pour la valider et mieux l’appréhender, cette dynamique de configuration du territoire en écologie industrielle. Le territoire constitue une matrice complexe, composée de représentations et de pratiques, manifestées dans le discours des acteurs. A partir de l’étude de 21 cas portuaires d’écologie industrielle à l’échelle internationale, 9 modèles territoriaux ont été proposés pour l’observer et la décrypter. Déclinés dans l’espace portuaire de Marseille-Fos, ces modèles permettent la production et l’interprétation des discours des acteurs de la démarche d’écologie industrielle en vue d’identifier les modalités de construction territoriale à l’œuvre et de construire une configuration du territoire à l’interface des représentations et pratiques des acteurs. Cette expérimentation met en évidence un phénomène d’imbrication territoriale de l’écologie industrielle et la participation de celle-ci à une dynamique territorialité-territorialisation structurante de la construction territoriale. Elle propose ainsi une définition socioécologique du territoire, distinguant des biotopes et des niches occupés par des acteurs, dont les interactions appellent à un renouvellement de la gouvernance portuaire de l’écologie industrielle
The circulation of material and energy flows reflects the functioning of both biosphere and human societies. Industrial ecology, in its territorial approach, questions these socioecological interactions within a geographical area. It contributes to the definition and structuration of land into territory. Through an experimental approach led upon port areas, the aim is to reveal this dynamic of territorial configuration in industrial ecology. Territory constitutes a complex matrix of representations and practices, uncovered in actors’ speeches. From the analysis of 21 industrial ecology port case studies at an international scale, 9 territorial patterns are defined in order to observe and interprete this dynamic. Implemented in Marseille-Fos port area, these patterns allow the production and the interpretation of actors’ speeches in order to identify the territorial construction modes and to build a common territorial configuration, at the interface of actors’ representations and practices. This experimentation highlights a territorial embeddedness phenomenon for industrial ecology. It reveales industrial ecology’s contribution to a “territoriality-territorialisation” dynamic, leading to territorial configuration. It thus proposes a socioecological definition of territory, identifying biotopes and niches occupied by different actors. The overlapping of these biotopes and niches questions the evolution of port governance for the implementation of industrial ecology

Abstract (sommario):

Electro-optic (EO) beam deflectors are voltage-controlled devices widely used for scanning and switching applications. For example, high-speed, low-loss optical switches aimed at future optical networks can be built on EO deflectors. Novel EO deflectors distinguish themselves with a much-improved steering performance, high-speed response and simple fabrication requirements. Patterned ferroelectric crystals such as LiTaO3 are first poled to provide the required prism shaped domain structures. The application of an electrical field across the entire crystal can then be used to drive the trajectory of the beam as it travels through the poled wafer. The electric field induces an index change of opposite magnitude on the adjacent domain regions in the EO device, causing the optical beam to refract at the interfaces.
Although rectangular geometry is extensively employed in EO devices, nonrectangular scanners have demonstrated better deflection performance. Two new nonrectangular geometries capable of further enhancing the deflection performance of EO beam scanners, proposed in this dissertation, were constructed. Their parabola and half-horn geometries provide 2-3 degrees of steering, which is 2-3 times greater than the steering provided by rectangular deflectors.
EO deflectors based on the parabola and the half-horn geometries, which can provide larger deflection angles, were built. These devices demonstrated a deflection angle of 3.1°, less than 5 dB of insertion loss from fiber to fiber, and -40 dB of crosstalk.
Two packaged optical switches using rectangular EO deflectors were demonstrated. By combining these EO deflectors with fiber collimators and high voltage packaging, high speed optical switches were built and characterized. The switch design was based on a 500mum z-cut LiTaO3 single crystal wafer fabricated using the domain inversion method. The 1x2 switch had a maximum deflection angle of 1.22° with an applied voltage of 1.1 kV and the 1x4 switch had a maximum deviation angle of 2.14°, with an applied voltage of 1 kV. The average insertion loss and crosstalk figures were 2.36 dB and -36 dB, respectively. The worst case switching time was 86 ns.

Abstract (sommario):

In this dissertation, a new satellite platform power architecture based on paralleled three-port DC/DC converters is proposed to reduce the total satellite power system mass. Moreover, a four-port DC/DC converter is proposed for renewable energy applications where several renewable sources are employed. Compared to the traditional two-port converter, three-port or four-port converters are classified as multi-port converters. Multi-port converters have less component count and less conversion stage than the traditional power processing solution which adopts several independent two-port converters. Due to their advantages multi-port converters recently have attracted much attention in academia, resulting in many topologies for various applications. But all proposed topologies have at least one of the following disadvantages: 1) no bidirectional port; 2) lack of proper isolation; 3) too many active and passive components; 4) no soft-switching. In addition, most existing research focuses on the topology investigation, but lacks study on the multi-port converter's control aspects, which are actually very challenging since it is a multi-input multi-output control system and has so many cross-coupled control loops. A three-port converter is proposed and used for space applications. The topology features bidirectional capability, low component count and soft-switching for all active switches, and has one output port to meet certain isolating requirements. For the system level control strategy, the multi-functional central controller has to achieve maximal power harvesting for the solar panel, the battery charge control for the battery, and output voltage regulation for the dc bus. In order to design these various controllers, a good dynamic model of the control object should be obtained first.; Moreover, this topology can be extended into n input ports which allow more input renewable sources. Finally, the work is summarized and concluded, and references are listed.; Therefore, a modeling procedure based on a traditional state-space averaging method is proposed to characterize the dynamic behavior of such a multi-port converter. The proposed modeling method is clear and easy to follow, and can be extended for other multi-port converters. In order to boost the power level of the multi-port converter system and allow redundancy, the three-port converters are paralleled together. The current sharing control for the multi-port converters has rarely been reported. A so called "dual loop" current sharing control structure is identified to be suitable for the paralleled multi-port converters, since its current loop and the voltage loop can be considered and designed independently, which simplifies the multi-port converter's loop analysis. The design criteria for that dual loop structure are also studied to achieve good current sharing dynamics while guaranteeing the system stability. The renewable energy applications are continuously demanding the low cost solution, so that the renewable energy might have a more competitive dollar per kilowatt figure than the traditional fossil fuel power generation. For this reason, the multi-port converter is a good candidate for such applications due to the low component count and low cost. Especially when several renewable sources are combined to increase the power delivering certainty, the multi-port solution is more beneficial since it can replace more separate converters. A four-port converter is proposed to interface two different renewable sources, such as the wind turbine and the solar panel, one bidirectional battery device, and the galvanically isolated load. The four-port converter is based on the traditional half-bridge topology making it easy for the practicing power electronics engineer to follow the circuit design.

Abstract (sommario):

Thesis (Masters Diploma (Engineering))--Cape Technikon, 1997
The idea for this study occurred when movement of the caisson extension to the breakwater was observed. The major concern was, what would happen if the caisson breakwater extension failed? What would the financial implications be to the port? The CSIR have carried out a number of studies with regards to the safety of the structure. The consequences of caisson failure and the possible effects on the port were however not investigated. When it was determined that settlement was taking place, information concerning the condition of the caisson structure and factors influencing the structure were gathered. Investigations on the following were done: (a) Extent of caisson settlement. (b) Sediment movement around the structure. (c) Foundation condition. (d) Wave impacts of long and short period waves on the Ben Schoeman Dock in the event of caisson failure. (Refraction and diffraction). (e) Financial implications due to possible container operation downtime at Ben Schoeman Dock in the event of caisson failure. (f) The tourist potential of the structure. The conclusion reached in this study was that the Ben Schoeman Dock would not be adversely effected if partial or complete failure of the main breakwater should take place. One could even question the length of the extension and whether it was actually required. The recommendations of this study would be as follows follows: Maintain the caisson extension in good condition as it will be important for possible future extensions to the port. Develop the breakwater as it is an asset which has potential for tourism to Cape Town.

Abstract (sommario):

AbstractThe Port of Yangon is the largest port in Myanmar and a river port located approximately 40 km upstream from the Yangon estuary. The country’s economic growth has led to the construction of a new container terminal in the Thilawa area, 16 km downstream from the Yangon port. Regardless of the difficult natural conditions in the area, project had to be completed in a short period at the request of the client. In order to shorten the construction period, construction of a jetty using the jacket method and soil improvement combined with the consolidation acceleration method were adopted. After repeated studies, the project was completed in a short period of 915 days. This paper describes the details of these studies.

Abstract (sommario):

AbstractGuangdong-Hong Kong-Macao Greater Bay Area is one of the most developed regions in China and a world-class manufacturing base. China has built a world-class port cluster with Hong Kong Port, Shenzhen Port and Guangzhou Port as the core members and a river-sea intermodal transport system based on the Pearl River Delta high-grade waterway network which features delivery of containers, coal, and grain. Promoting the high-quality development of the Guangdong-Hong Kong-Macao Greater Bay Area, achieving carbon peaking by 2030, and achieving carbon neutrality by 2060 are major strategies for China’s future development. To realize these goals, China will further promote the construction and development of the Guangdong-Hong Kong-Macao Greater Bay Area port cluster, and will also pay more attention to environmental advantages such as high inland water transport capacity, low energy consumption and low pollution. Meanwhile, the government will make further reforms in planning, construction and institutional mechanism to accelerate the improvement of the river-sea intermodal transport system around the core ports in the Bay Area. This paper systematically reviews the layout, construction, and development of ports in the Guangdong-Hong Kong-Macao Greater Bay Area, the Pearl River Delta high-grade waterway network, and the river-sea intermodal transport system around seaports since the 1980s. Based on the “Outline of the Development Plan of Guangdong-Hong Kong-Macao Greater Bay Area”, this paper foresees the future development trend of the port cluster and its river-sea intermodal transport system from the perspectives of inter-port relationship, high-grade waterway network and river-sea intermodal transport hub.

Abstract (sommario):

The US Army Corps of Engineers, Galveston District, is executing the Sabine Pass to Galveston Bay Coastal Storm Risk Management (CSRM) project for Brazoria, Jefferson, and Orange Counties regions. The project is currently in the Pre-construction, Engineering, and Design phase. This report documents coastal storm water level and wave hazards for the Port Arthur CSRM structures. Coastal storm water level (SWL) and wave loading and overtopping are quantified using high-fidelity hydrodynamic modeling and stochastic simulations. The CSTORM coupled water level and wave modeling system simulated 195 synthetic tropical storms on three relative sea level change scenarios for with- and without-project meshes. Annual exceedance probability (AEP) mean values were reported for the range of 0.2 to 0.001 for peak SWL and wave height (Hm0) along with associated confidence limits. Wave period and mean wave direction associated with Hm0 were also computed. A response-based stochastic simulation approach is applied to compute AEP values for overtopping for levees and overtopping, nappe geometry, and combined hydrostatic and hydrodynamic fluid pressures for floodwalls. CSRM crest design elevations are defined based on overtopping rates corresponding to incipient damage. Survivability and resilience are evaluated. A system-wide hazard level assessment was conducted to establish final recommended system-wide elevations.

Abstract (sommario):

On 14 August 2021, Haiti was hit by a magnitude 7.2 earthquake with an epicentre in the Canal du Sud (120 km west of the capital, Port-au-Prince). The earthquake killed over 2,200 people and injured more than 12,000. The vulnerability of the Haitian people to such a disaster can be traced back through centuries of colonial exploitation, resource extraction and political instability; displaying very clearly that disasters are byproducts of the societal construction of risk. This technical background report for the 2021/2022 edition of the Interconnected Disaster Risks report analyses the root causes, drivers, impacts and potential solutions for the Haiti earthquake through a forensic analysis of academic literature, media articles and expert interviews.
