Abstract1997 was an important year for Russia's Northern Sea Route (NSR) in terms of foreign interest. The first full transits of the NSR by western merchant ships were made. The International Northern Sea Route Programme (INSROP) continued into phase 2 of its research projects, and planning proceeded for a European Union-sponsored demonstration voyage to the Ob' River. The nuclear icebreaker Arktika returned to Arctic operations, while two icebreakers were removed from polar service. Information about the NSR became more widely available with the distribution of an English translation of a navigation guide. Winter operations continued in the Kara Sea, albeit reduced, and a limited number of summer voyages to Russian Arctic ports originated from the Pacific rim. RADARS AT synthetic aperture radar images of sea ice along the NSR were used for the first time during several demonstration voyages.

Abstract Main problem for scheduling vessel transit voyages through the Northern Sea Route is the difficulty in predicting distribution of ice boundaries in regions that cannot be overcome by individual ice classes of vessels. Scheduling of voyage is related to speed that vessels can develop and moment of time when vessels will be able to commence and complete passage safely through areas that are main obstacle and are blocking longest transit passage through the Northern Sea Route. This applies to voyages carried out by vessels navigating on their own and with support of icebreakers. Additional problem is lack of consistency of content of maps of ice cover, which can be used for vessels voyage planning through areas where ice cover occurs. Results of this research on influence of uncertain information related with time window of conditions favorable for navigation of vessels of different ice classes on schedule of theirs voyage on example of summer navigation season 2017 are presented in this work.

The State of Indonesia is a country which is according to cultural history and in the days of the kingdom is a maritime country. The country of Indonesia with the largest islands covers the largest sea, the largest island, and the second longest beach in the world. On this basis, Indonesia currently has a modern port as well as a port for people's voyages. People's voyages are generally identical to traditional wooden boats operated by natural sailors with simple management (Law No. 17/2008 on the voyage of articles 15, paragraphs 1 and 2). The demands of global business are causing people's shipping today to be marginalized.Some problems in the voyage of the people include the procurement of the shipping fleet is hampered by the difficult supply of logs, so it needs to look for other alternatives. Another problem is the guarantee of safety and good service from the voyage of the people The government plans to build the People's Port. This port will be built with a good security system. The sailing of people with the zone of its own. People's voyages are still needed, because remote areas that are not crossed by large auto ships are still dependent on small ships such as KLM or PLM. In addition, there is a dock that can not be enclosed by iron vessels or shallow harbors. The voyage of the people can overcome it, thus helping national transpotation.Indonesia as the largest archipelago country still requires the voyage of the people as one mode of inter island transportation. The Government is committed to memordenisasi and improve the safety and security of people's shipping by still considering local wisdom. Another problem is the guarantee of safety and good service from the voyage of the people.

The opening of arctic routes provides a new option for international navigation ships. The correlation between ship movement characteristics and ice conditions should be known, which will help ships adapt to the polar waters. Based on the voyage data and sea ice manual observation data of the ‘XUE LONG’ ship’s six voyages in polar waters, a correlation analysis model of ice conditions and ship movement characteristics was established in this work. First, the ship movement characteristics in polar waters were analyzed, such as the distribution characteristics of ship speeds, courses, and variation characteristics by using the descriptive statistical analysis method and data visualization analysis method. Then, by using multivariate correlation analysis and univariate controlled correlation analysis methods, the correlation between movement characteristics and ice conditions, such as ice concentration and thickness, and the correlation between different ice conditions themselves, were quantitatively analyzed. The result shows that the correlation analysis model of ice conditions and ship movement characteristics is reliable and effective and can obtain quantitative correlation analysis results. On the one hand, sea ice thickness has almost no significant correlation with ship movement characteristics, excluding the influence of sea ice concentration. On the other hand, excluding the influence of sea ice thickness, sea ice concentration is still significantly correlated with the absolute value of speed, speed variation, and course variation. The conclusions of this work have important reference significance for polar scientific investigations, commercial ships’ voyages in icy waters, and ships’ designs for icy waters.

This paper realizes the simultaneous optimization of a vessel’s course and speed for a whole voyage within the estimated time of arrival (ETA), which can ensure the voyage is safe and energy-saving through proper planning of the route and speed. Firstly, a dynamic sea area model with meteorological and oceanographic data sets is established to delineate the navigable and prohibited areas; secondly, some data are extracted from the records of previous voyages, to train two artificial neural network models to predict fuel consumption rate and revolutions per minute (RPM), which are the keys to route optimization. After that, speed configuration is introduced to the optimization process, and a simultaneous optimization model for the ship’s course and speed is proposed. Then, based on a customized version of the A* algorithm, the optimization is solved in simulation. Two simulations of a ship crossing the North Pacific show that the proposed methods can make navigation decisions in advance that ensure the voyage’s safety, and compared with a naive route, the optimized navigation program can reduce fuel consumption while retaining an approximately constant time to destination and adapting to variations in oceanic conditions.

This article analyses the first three English ventures into the Red Sea from 1608–1614 under the auspices of the East India Company's fourth, sixth, and eighth voyages. These ventures experienced a variety of disasters from shipwreck, captivity, mutiny, and the deaths of crewmembers. The sixth voyage, commanded by Henry Middleton, experienced the worst of the disasters. Middleton ran afoul of Ottoman officials in the port city of Mocha in Yemen and was taken in chains to the regional capital of Sana'a. He eventually escaped and returned to the Red Sea to seek revenge by blockading the port and committing acts of piracy. Middleton's actions reverberated back to Istanbul and London, where the main point of contact between England and the Ottoman Empire, the Levant Company, was forced to deal with the fallout in order to maintain its presence in the Sultan's dominions. The article argues that, despite the failures of these voyages, they reveal a great deal about the nature of overlapping jurisdictions and sovereignty in the early modern world, and furthermore they provide an important window into the evolution of corporations into entities capable of putting together empires amongst these disparate jurisdictions.

In an earlier study I described the material on Morocco, the Saharan coast, sub-Saharan Africa, and the neighboring Atlantic islands, which appeared in Richard Hakluyt's collection of English voyages, in its two editions of 1589 and 1598-1600. Up to his death in 1616 Hakluyt continued to collect additional material for an intended third edition. This material passed to Samuel Purchas (1577-1626), an Essex and then London clergyman, who had already begun to collect and publish voyage material on his own account.In 1613 Purchas published his Pilgrimage, which appeared again in progressively enlarged editions in 1614, 1617, and 1626. Pilgrimage presented a synthesis of contemporary knowledge of the outer continents, based on accounts of voyages and journeys to and descriptions of exotic lands, some of them published, others from manuscripts collected or inspected by Purchas, the whole notionally organized as a review of religious practices throughout the world. Although Pilgrimage cites a vast range of sources and sometimes quotes from them, the work is basically a summarizing of the sources in Purchas' own words. Of much greater interest, therefore, is Purchas' other major work, his masterpiece, his Pilgrimes, which appeared in 1625 in four very large volumes running to some 4000 pages. Pilgrimes is a collection of sources, on the model of Hakluyt's collection, though Purchas more frequently presents his sources in cut versions. The material covers voyages and journeys to all parts of the known world, and is not limited to English voyages--the major limitation being only the extent of material Purchas could lay his hands on.

There are long-standing and ongoing concerns about the welfare of animals in the Australian live export trade by sea. However, scrutiny of animal welfare on board vessels is generally hindered by a lack of independent reporting. Cattle voyages from Australia to China have concerned animal welfare advocates due to their long duration and lack of consistent veterinary oversight. In April 2018, following a media exposé of animal cruelty and declining public trust, the Australian government installed Independent Observers on some live export voyages. Summaries of Independent Observer (IO) reports by the Department of Agriculture and Water Resources (DAWR) provided a new and independent source of information about management of animals in the live export trade. The IO summaries on live cattle export voyages to China for the period July 2018 to December 2019 (n = 37) were reviewed. The IO summaries detailed voyages that carried 147,262 slaughter, feeder or breeder cattle which included both dairy and beef breeds. The long-haul voyages averaged 20 days in duration, generally departing the ports of Fremantle and Portland and discharging at ports in northern China. Key animal welfare risk factors identified in the IO summaries included: hunger, thirst, exposure to extreme temperatures, poor pen conditions, health issues, absence of veterinarians, rough seas, poor ship infrastructure, mechanical breakdown and mismanagement at discharge.

In the article there is considered the problem of the impact of factors of the long voyage on the body of sailors-operators of logical and sensory profile of the activity. The aim of the study is to estimate indices both of body functions and performance of marine specialists operators of video display terminals during the long voyage. The experimental group included 27 crew members from the command, the Navigator group, group of locations and communications, professionals exploiting videodisplay terminals. Functions of operators bodies during the period 65-day voyage were studied with the use of the techniques of the assessment of indices of the subjective status, cardiorespiratory, central nervous system and physical performance. There were established adverse changes in the functional state of the organism, pronounced by the decline in levels of conditioned-reflex activity, the exertion of the cardiorespiratory system at rest and in the deterioration of physical performance from the second month of sailing and persisting until the end of the voyage, despite the optimal level of factors of the habitability at the ship. The leading adverse factors included the decrease of the motor activity by 2.5 - 3 times if compared to pre-trip levels and the intense operator activity. This necessitated the development of manners and means of the preservation of the occupational health of seafarers-operators in long voyages, as well as the improvement of the hygienic regulations of the conditions of their professional activity in the courts.

This dissertation is concerned with the idea of play. It argues for seeing play in Foucaultian terms, not as a privileged 'object' existing concretely in the world, but as discursively constructed in a range of intersecting and sometimes competing fields. Two orders of discourse that produce play, one explicitly and one implicitly, are investigated here for the ways in which they contribute to constructions of power. In the first, scholarly discourse systematically constructs play as a problem that can only be understood through the academic practices of reading, writing, and 'objective' analysis, privileging reason as the hegemonic way of knowing and the scholar as authority. An archaeological analysis demonstrates how this discourse constructs the academic as an external observer rather than as a player, systematically 'writing out' not only the playing subject, but also the imaginative, performative, and sensuous knowledges of play. In the second order of discourse studied here, the re-enactment of legendary sea voyages, these knowledges are privileged. A genealogical analysis demonstrates how these disparate seafaring events systematically construct a discourse of play through voyagers' imaginative performance of discourses of, for example, exploration, adventure, masculinity, and legend. Attention to the construction of power in these voyaging performances also functions to provide a critique of the academic discourse of play. Alternating chapters on scholarly and voyaging discourses thus productively illuminates the struggle over knowledges of play and of the past - but also for the authority of different ways of knowing.

Der volle Inhalt der QuelleAnnotation:
This thesis is about the historical geography of scientific knowledge production at sea. It focuses on three expeditions of exploration and discovery undertaken, respectively, by France, the United States of America, and Britain, that in the late 1830s sailed into the southern oceans. These voyages marked the last such expeditions to travel by sail alone and came before an acknowledged period of specialized interest in investigating the oceans and the marine environment, exemplified by the sailing of HMS Challenger in 1872. The expeditions share a commonality of period and of destination: their study together provides a hitherto overlooked opportunity to analyse practices of experimentation on, and investigation of, the natural history and physical properties of the marine environment that were integral to the construction of scientific knowledge about the oceans at that time. By attention to archival records, personal correspondence, diaries, published travel narratives and representations of marine phenomena in the form of illustrations, sketches, preserved specimens and displays of numerical material, this thesis examines quotidian shipboard practices to show how the production of scientific ‘facts’ was a matter of constant negotiation between people, weather, instruments and vessels – that occurred as a by-product of the running of the ship as well as of more defined programmes of study by civilian naturalists and naval staff. Informed by work in the history of science, Science and Technology Studies (STS) and Actor-Network Theory (ANT), this thesis highlights how attending to practice in the ambiguous, heterotopic space that was the expedition vessel can reveal the origins of a new, specialized, discipline: what I call here a proto-oceanography. This covers those scientific practices undertaken primarily at sea and from the ship: depth measurement, sea temperature and chemistry, the height of waves, collection of marine specimens and coastal topography, but not those primarily land-based activities such as astronomy, meteorology and terrestrial magnetism. By focusing on work carried out on board ship rather than on land, this thesis offers new insights into the practices of marine investigation and experimentation and the complexities of interrogating a space which was visualised primarily through instruments. This thesis examines how at-sea cultures of collection, measurement and representation can inform geographically nuanced analyses of the production of scientific knowledge.

Dans les récits de voyages des années 1800, la région de la mer Baltique est présentée commeun espace de découverte diversifié – c’est en quelque sorte un patchwork multicolore deconstructions imagologiques. Pourtant, la conception d’une région de la mer Baltique étaitdéjà fondée à l’époque de la «Sattelzeit» sur le besoin de pouvoir situer les riverains de la merBaltique comme une unité culturelle, quelque part dans le grand Nord. Dans l’imaginationdes voyageurs en 1800, la région de la mer Baltique est en fait déjà cet espace d’interactionset d’imbrications qui constitue la base évidente des approches modernes de la recherche.Bien sûr, il y avait les divers royaumes, provinces ou villes qui jouèrent un rôle pour lesvoyageurs. Cela ne signifie pourtant pas qu’il soit impossible de retrouver dans les récits devoyages certains points communs, manifestés sous forme d’un caractère «nordique»supérieur de ces riverains. C’est pourquoi ce caractère «nordique» est sans cesse exprimédans les récits de voyages à partir de divers niveaux de perception – dans la description de lanature, de la mer, du climat, mais aussi dans les perceptions des villes et les rencontresculturelles. Par conséquent, la littérature de voyage indique une tendance qui est égalementimportant pour la recherche historique actuelle: une évaluation de la région de la merBaltique comme un macro-région unique, qui accepte aussi les différences dans leursdifférents pays et régionsThis Franco-German analysis examines the Baltic Sea region as a center for cultural exchangebased on German and French travel reports from 1750 to 1815 in a comparative perspective.The objective is to examine the countries around the Baltic Sea as places of encounter fortravelers and to raise the awareness of historical travel research and research of culturalexchange for the subject ‘space’. This approach scrutinizes several forms of German andFrench imaginations of nature, sea shore and different forms of urbanity, but also theperception and reception of identities and alterities, the consolidation and the departure ofstereotypes as well as the possibilities and limits of cultural transfer processes by travelling.Furthermore, this approach allows to gain a deeper understanding of the progress of complexphenomena such as, ‘percipience', 'contemplation' and 'delineating' of foreign cultures in aperiod which was marked by a radical change in socio-political and cultural thinking

On 10 February 1964 during naval night exercises off the south coast of Australia, the destroyer HMAS Voyager was lost after colliding with the aircraft carrier HMAS Melbourne. 82 men were killed. Following the collision, there were two Royal Commissions that sustained a political controversy that lasted for over four years. This thesis examines the loss of Voyager as a watershed in the operational and administrative history of the RAN and as a major event in Australian national history. This study has four broad objectives: to describe the loss of Voyager and the long running controversy that accompanied the disaster; to offer a convincing explanation of the causes of the collision and why two royal commissions concluded that the causes for the disaster were inexplicable; to assess the effect on the RAN, in terms of specific reforms and its influence on Service culture and professional ethos, of the disaster and the inquiries that followed; and finally, to analyse the loss of Voyager as a media and political cause celebre in Australian history. As so little has been written about Voyager using primary sources, this thesis was committed to detailed description of events as well as analysis of themes. This thesis draws upon an extensive body of primary source material in the form of official naval and Royal Commission records to which complete access was given; several large collections of private papers; over one hundred interviews with principal participants; and comprehensive files of press cuttings. The discussion seeks to demonstrate that a series of naval accidents preceding the loss of Voyager contributed in a substantial way to shaping the public reaction to, and political handling of, the disaster; that the method of inquiry played a major role in generating public and political disquiet; that the collision was both a catalyst and stimulus to change in naval operations and reform in naval administration; that the inability of two Royal Commissions to ascertain the causes of the collision and then to public suspicion of a cover-up; and, that the collision was most probably caused by the incorrect relaying of a tactical signal on the bridge of Voyager. The loss of HMAS Voyager appears to be a key event in the development of the RAN, not as a direct result of the collision or its causes, but as a consequence of its long and controversial aftermath.

Der volle Inhalt der QuelleAnnotation:
This research study seeks to evaluate the techno-economic and environmental
implications of a variety of aero-derivative marine gas turbine cycles that have
been modelled for the propulsion of different types of merchant ships. It involves
the installation and operation of gas turbine propulsion systems in different
marine environmental conditions and aims to evaluate the effect of the
aerodynamic and hydrodynamic variations expected to be encountered by
these ships when they navigate across different climates and oceans along
selected fixed trade routes.
A combination of simulation tools developed in Cranfield University at the
Department of Power and Propulsion including the validated gas turbine
modelling and simulation code called “Turbomatch” and the “APPEM”
simulation code for the analysis and Prediction of exhaust pollutants have been
used along with the ongoing development of an integrated marine gas turbine
propulsion system simulation platform known as “Poseidon”. It is the main
objective of this research to upgrade the competence level of “Poseidon” so as
to facilitate the conduct of a variety of longer and more complex oceangoing
voyage scenarios through the introduction of an ambient temperature variation
numerical module. Expanding the existing code has facilitated the prediction of
the effect of varying aerodynamic and hydrodynamic conditions that may be
encountered by gas turbine propulsion systems when such ships navigate
through unstable ocean environments along their fixed trade routes at sea.
The consequences of operating the marine gas turbines under ideal weather
conditions has been investigated and compared with a wide range of severe
operating scenarios under unstable weather and sea conditions in combination
with hull fouling has been assessed. The techno-economic and environmental
benefits of intercooling/exhaust waste heat recuperation of the ICR model have
been predicted through the evaluation of different ship propulsion performance
parameters in a variety of voyage analysis leading to the prediction of fuel
consumption quantities, emission of NOx, CO2, CO and UHCs and the estimation of the HPT blade life as well. The different gas turbine cycle
configurations of the research were found to respond differently when operated
under various environmental profiles of the ship’s trade route and the number of
units for each model required to meet the power plant capacity in each scenario
and for each ship was assessed. The study therefore adds to the understanding
of the operating costs and asset management of marine gas turbine propulsion
systems of any ocean carrier and in addition it reveals the economic potentials
of using BOG as the main fuel for firing gas turbine propulsion plants of LNG
Carriers.

Der volle Inhalt der QuelleAnnotation:
This thesis explores the relationship between migration and disease in c.1830 – c.1860. Each chapter questions how convicts, emigrants and the surgeons who accompanied them thought about disease and in turn how disease changes how we understand migration historically. It is a study of the creation of medical knowledge across the geographical space of the voyage to Australia and emphasises an understanding of disease as a mental and physical interaction between humans and their environment. The thesis argues that this understanding allowed migrants and colonists to see disease at sea as a test of migrants’ and convicts’ fitness to colonise. The point of departure for this thesis is that the Australian sailing voyage provides a unique and prolonged tension between shipboard confinement and global movements through ever-changing, often extreme, oceanic climates. From this premise, six individual chapters follow the trajectory of the voyage from Britain to Australia. These chapters analyse individual disease such as cholera, fevers, scurvy and consumption, as well as deepening our understanding of the tropics and quarantine by rethinking these histories through a maritime dynamic. Throughout, the thesis analyses evidence in convict and emigrant ship surgeons’ journals, migrants’ diaries and published medical literature as its primary source material, supplemented by government reports and contemporary newspapers. Collectively, the chapters of the thesis connect conventionally separate histories of medicine, convict transportation, colonial emigration, and British welfare and prison reform. By exploiting a uniquely maritime tension between shipboard confinement and global migration, the thesis provides a new way to understand the persistence of ideas about the relationship between people, environment, migration and disease in the modern period.

Abstract Ocean-going vessels are under the continuous influence on the effect of the weather, e.g. wind, waves, ocean currents. Since the weather conditions are random in nature, there are situations where the shipmaster changes the ship speed or/and heading of the original sailing path to avoid harsh weather conditions according to his judgment, experience and/or using voyage optimization systems (e.g. weather routing systems). However, ship operators hardly prioritize the ship fatigue routing in their operations. It is preferable to consider the effect of different wave environment due to ship operation in the design process to make a more rational ship design of the structural members. In this study, sailing paths are planned, adopting voyage optimization in order to reduce the probability of encountering severe sea conditions and the minimization of the fatigue accumulation in ship structures. Short-sea sequences are generated by a statistical wave storm model. The storm profiles are determined by using the cumulative frequency of short-seas which are experienced in the different voyages optimized by the algorithm. The influence of the difference in short-seas encountered by the target ship following the optimized voyages on the cumulative damage is demonstrated by a container vessel, which also considers a weather routing system in her operations. Full-scale measurement data for two years’ voyages are considered for the verification. The benefits of using voyages optimization systems focus on reducing fatigue damage to mitigate the risk of structural failure is discussed.

Abstract Two historical voyages were completed in December 2021 and January 2022 over the Northern Sea Route (NSR) in a westerly direction. A lack of accurate real time data regarding ice conditions and the influence of changing meteorological conditions severely complicated voyage planning. Normal voyage planning for the Northern Sea Route is based on historical satellite data. The objective is to extrapolate possible ice conditions throughout the planned route. This historical data has not been taken into account changes in wind, current and relative ice pressure. In addition, the effect of wind drag on the "sail area" of modules being transported has a significant influence on the application of the power necessary to penetrate ice at the speed and fuel consumption calculations stipulated by the Vessels’ design. The safe transit of the Northern Sea Route from the beginning of December to the end of March cannot be accurately predicted by using the historical data available today. This significantly increases the risk factors considered not only in pre-voyage planning but throughout the voyage itself. The application of the current regulatory regime requirements to navigate via the Northern Sea Route during the December-March period by no means eliminates the possibility of vessels becoming beset by ice. Close communication with Rosatomflot prior to entering the Northern Sea Route is a necessity in order to appraise the ice conditions in higher risk areas as well as to optimized route planning. Furthermore, operational experience during periods of nuclear icebreaker support is critical to maintain safe progress on the Northern Sea Route. This Paper will address these challenges, as well as attempt to quantify: The effect on wind pressure and wind direction on icebreaking capabilitiesThe effects of wind speed and direction on ice pressure relative to coastal geography.The effects of changing ice conditions on fuel consumption with- and without icebreaker support.

In this paper, the authors proposed a ship weather-routing algorithm based on the composite influence of dynamic forces, i.e. wind, wave and current forces, for determining the optimized transoceanic voyages. Our developed routing algorithm, three-dimensional modified isochrones (3DMI) method, utilizes the recursive forward technique and floating grid system for both the east- and west-bound ship routes in the North Pacific Ocean. In order to achieve the goals of minimized fuel-consumption or the maximized-safety routes for the transoceanic voyages, two sailing methods are applied as the prerequisite routes in the earth coordinate systems. The illustrative analysis of ship routes has been presented and discussed based on the realistic constraints, such as the presence of land boundaries, non-navigable sea, external forces, parametric roll responses as well as ship speed loss. As a result, the proposed calculation is verified to be effective for the optimized sailings by adjusting the weighting parameters in the objective functions.

Problems of radiative transfer in seawater are unique because the volume scattering function σ(θ) is sharply peaked in the forward direction. Consequently, angles of interest vary over 3.5 orders of magnitude (1 rad to 180°). The smallest angles blur vision, while the larger ones affect illumination, photosynthesis, signalling by light beam, etc. Not surprisingly, no one theory of radiative transfer is convenient for such a broad range of angles, nor is one class of meter appropriate for all measurements. We have developed unconventional instruments for both the small angels (cos θ ~ 1) and the large ones (θ > 29°). The former is based on MTF theory, the latter on the spherical harmonic technique for radiative transfer. The small-angle meter is based on a resolution test pattern (bar charts). These spatial frequencies have a simple dependence on distance: they decay exponentially. For large angles, we have built a radiometer that measures ten integral moments of radiance as a function of depth. From these data we infer nine spherical moments of σ(θ). Data reduction inverts the equations of radiative transfer, which avoids some limitations of conventional instruments. Two voyages have yielded satisfactory results and suggested improvements using lamps and simultaneous readings of the ten moments.

Recently, the research activities by domestic and overseas researchers using the Korean ice-breaking research vessel, ARAON have been actively conducted. The ARAON regularly operates for research activities in the Antarctic and the Arctic Ocean every year. She conducts many scientific and engineering tasks including ice load measurement, investigation of the properties of material strength for sea ice, and icebreaking performance test during her voyages. Such tests provide important data for studying icebreaker. Ice-breaking mode is determined by conditions of sea ice and ice field, and it is divided into ramming and continuous icebreaking. When the icebreaker meets thick ice or icebergs, the ramming is conducted. At that time, the ship speed is generally slower than that of the continuous icebreaking. The ARAON conducted icebreaking performance tests at the Amundsen Sea in Antarctica in 2012. Many strain data were measured in the ramming and the continuous icebreaking. This study was based on the strain gauge signals measured by the ARAON during the research voyage in 2012 in the Antarctic and 2010 in the Arctic. The signals measured from repetitive ramming under the heavy ice condition in 2012 in the Antarctic Ocean were classified into the five profiles. And the classified ice load signals were analyzed with a focus on raising time, half-decaying time and total time duration. Also, the signals measured from continuous icebreaking in 2010 in the Arctic Ocean were analyzed in the same way as the ramming data. Finally, the time histories of ice load signals were summarized from the viewpoint of speed change at the time of ice load, and two data sets were compared.

Abstract The development and evaluation of energy efficiency measures to reduce air emissions from shipping strongly depends on reliable description of a ship’s performance when sailing at sea. Normally, model tests and semi-empirical formulas are used to model a ship’s performance but they are either expensive or lack accuracy. Nowadays, a lot of ship performance-related parameters have been recorded during a ship’s sailing, and different data driven machine learning methods have been applied for the ship speed-power modelling. This paper compares different supervised machine learning algorithms, i.e., eXtreme Gradient Boosting (XGBoost), neural network, support vector machine, and some statistical regression methods, for the ship speed-power modelling. A worldwide sailing chemical tanker with full-scale measurements is employed as the case study vessel. A general data pre-processing method for the machine learning is presented. The machine learning models are trained using measurement data including ship operation profiles and encountered metocean conditions. Through the benchmark study, the pros and cons of different machine learning methods for the ship’s speed-power performance modelling are identified. The accuracy of various algorithms based models for ship performance during individual voyages is also investigated.

It is well-known that navigating the waterway from the primary trade hubs in northern Europe to the Asia-Pacific ports and contrariwise along the Russian Arctic Coast (Northern Sea Route - NSR) is much shorter and faster, than southern ways via Suez or around Africa. The NSR can significantly save costs (through saving time and fuel) and avoids the risk of attack by pirates. In addition, an increase in oil and gas activity in the North, forecasts of global warming and an ice-free Arctic have stimulated interest in Arctic navigation. However, Arctic transportation poses significant challenges because of the heavy ice conditions that exist during both the winter and summer. The profitability of using the NSR is called into question if possible high tariffs are included in the cost estimates. For many years, the NSR was principally used for internal Russian transport and since the end of the 1980s up until 2010, it was in stagnation with total amount of cargo transported annually stood at less than two million tons. Important political decisions in the 90s and increased economic feasibility intensified traffic and freight turnover. In 2013, the NSR Administration (NSRA) was established, new rules for navigation were approved and tariff policies were modified. In 2013, the NSRA issued 635 permits to sail in NSR waters, and 71 transit voyages have since been completed. The total amount of transit cargo was 1.36 million tons. More than 40% of the total number of permits were issued to vessels without ice class [1] according to the Russian Maritime Register of Shipping [2]. There are strong technical requirements for vessels attempting to sail the NSR; regardless, several accidents occurred in 2012–2013. Two vessels were dented by ice in the Chukchi Sea in 2012. A tanker was holed in September 2013 and created a real danger of an ecological disaster from fuel leakage for several days. Despite the expectation of an ice-free Arctic, the ice conditions in 2013 were rather difficult, and the Vilkitsky Strait (a key strait in the NSR between the Kara and Laptev seas) was closed by ice for almost the entire navigation period. In this paper, we review the current situation in the Russian Arctic, including political and administrative actions, recent accidents and the associated conditions and lessons learned.

Nautical tourism is a growing sector that records excellent tourist results even in this uncertain time of the pandemic covid 19. According to the statistical data, an increasing number of people use the tourist offer of nautical tourism and cruising. Modern tourists need more than just accommodation and food. They are looking for a more sophisticated tourist offer and they find it in destinations that offer a diverse touristic product. Sea voyages or cruises record constant growth and resource development. With a nautical charter, the focus on the peak season is slightly smaller than is the case with the overall tourist traffic, while at the same time the share of pre-season and post-season is higher. In this way, the negative consequences of the seasonality of tourism are mitigated. Today in the time of the pandemic, this is an ideal type of vacation because it is less massive, with limited capacities and fluctuations.

The COVID-19 pandemic has brought about unprecedented challenges, including lockdowns, difficulties inverification, staff swaps, and restricted international travel. These factors underscore our globalunpreparedness for such crises. While these challenges have significantly affected life on land, their impact onmaritime activities has been even more pronounced.Life at sea has been particularly strained due to the inability to disembark, prolonged voyages resulting fromorganisational replacements, limited access to hospitals during sea travel, and challenges in early illnessdiagnosis and effective isolation. These hurdles have collectively made navigating the pandemic exceptionallydifficult for maritime communities.Within the framework of the DESSEV project, funded by the European Union Erasmus+, a DEcision SupportSystem (DSS) addressing epidemic threats on sea-going vessels has been developed. This initiative includesthe establishment of a learning repository and knowledge base on infectious diseases. The repositoryencompasses WHO recommendations, IMO guidance, and procedures from select countries for managingindividuals with symptoms or an imminent case of infection on board. Additionally, the repository includesdetailed medical cases presented in the form of scientific articles, all of which are accessible free of charge onthe project website, www.dessevproject.eu.A second key objective of the project was the creation of a database on infectious diseases. This databasecomprises 22 infectious diseases described with 35 symptoms, grouped into 8 categories. The accumulatedknowledge serves as the foundation for the development of IF...THEN... rules in the form of decision trees.This article presents the tangible results achieved through the DESSEV project. It provides insights into howthe project has contributed to addressing the unique challenges faced by crews of sea-going vessels during thepandemic, offering a valuable resource for maritime communities and public health professionals.

This study deals with the Khorasan wisdom starting from Turkestan and reaching the Balkans and the course of this wisdom in Azerbaijan. The general name of this wisdom, which developed and matured in Turkestan and Khorasan and was named and systematized as Khorasan wisdom, is Fütüvvet. Fütüvvet is based on the principle that all people are servants of Allah and among these servants, orphans, slaves and captives are served without expecting a fee or thanks. The communities that moved from Turkestan and Khorasan and reached the Balkans were also affiliated with this Fütüvvet. This article is about Azerbaijan's Ma‘rifa and affiliated communities starting from Turkestan and reaching from Anatolia to the Balkans, Iraq, Syria and Lebanon. Throughout the article the article aims to reveal in which places the Fütüvvet and its carriers, which are defined as Turkistan - Khorasan wisdom, have settled and their seyr ü sefer with this settlement. Turkestan - Khorasan Ma‘rifa has influenced many different communities in a very wide area and time with its seyr ü sefer, and the influence has continued until today. In this study, the importance, scope and limitations of the subject will be established by referring to the basic concepts on which the subject is based such as Fütüvvet, Turkestan-Khorasan, Azerbaijan and seyr ü sefer. In this context, Azerbaijan is geographically located between Turkestan, Khorasan, Anatolia and the Balkans as a line and belt from the Caspian Sea to Lake Urmia. Its geographical location has made it a place of social, cultural, wisdom and thought. Azerbaijan has fulfilled its mission, which was bestowed upon it by its remarkable position and which it carries with dignity, until today and continues to be the belt that connects geography, community, wisdom and thought. Keywords: Turkestan, Khorasan, Azerbaijan, Fütüvvet, Anatolia, Balkans.

In 2021, recreation visits to National Park Service (NPS) sites rebounded from the COVID-19 pandemic-driven low visitation of 2020 and climbed to 297,115,406 recreation visits. This is an increase of 60 million recreation visits (+25.3%) from 2020 and a decrease of 30 million recreation visits (-9.3%) from 2019. Recreation visitor hours were 1,356,657,749 – a 28.6% increase from 2020 and a 5.1% decrease from 2019. Total overnight stays followed a similar pattern with 12,745,455 overnight stays – up 4.7 million (+58.5%) from 2020 and down 1.1 million (-8%) from 2019. Five parks were added to the reporting system in 2021: Alagnak Wild River in Alaska, Camp Nelson National Monument in Kentucky, Medgar and Myrlie Evers Home National Monument in Mississippi, Tule Springs Fossil Beds National Monument in Nevada, and World War I Memorial in Washington, D.C. These parks were responsible for over 629,000 recreation visits in 2021. Factors influencing visits to National Park System units in 2021 include: continuing closures and limited capacities due to COVID-19 mitigation at some parks, temporary closures for wildland fires in 2021 (eleven parks), severe regional smoke/haze from ongoing wildland fires throughout the summer and early autumn affecting parks in the western half and northern tier of states in the continental U.S., two hurricanes in 2021 – both in August – impacted visitation: Hurricane Henri caused temporary closures of some parks in the northeast and Hurricane Ida caused temporary closures of parks along the Gulf Coast and generated some heavy flooding in the northeast, hurricanes and wildland fires in previous years resulting in lingering closures, most notably Hurricanes Irma and Maria in 2017, the Carr and Woolsey Fires in 2018, Hurricane Dorian in 2019, the Caldwell, Cameron Peak, East Troublesome, and Woodward Fires in 2020, and Hurricane Sally in 2020. Forty-four parks set a record for recreation visits in 2021 and 6 parks broke a record they set in 2020. See Appendix A for a list of record parks. The number of reporting units with over 10 million recreation visits was the same as in recent years (3 parks) and 73 parks had over 1 million recreation visits. Twenty-five percent of total recreation visits occurred in the top 8 parks and fifty percent of total visitation occurred in the top 25 parks. Several parks passed annual visitation milestones including Capulin Volcano NM which passed 100,000 annual recreation visits for the first time, Big Bend NP and Devils Tower NM which each passed 500,000 annual recreation visits for the first time, and Zion NP which passed 5 million visits for the first time. Other parks passed milestones for accumulated recreation visits including Hamilton Grange NMEM (1968-2021) and Palo Alto Battlefield NHP (2003-2021) each passing 1 million total recreation visits, Voyageurs NP (1976-2021) passing 10 million total recreation visits, and Hot Springs NP (1904-2021) passing 100 million total recreation visits. Population center designations were updated in 2021 to reflect overlap of park boundaries with statistical areas from the 2020 U.S. Census. Many population center changes reflect increases in local population as indicated by parks changing from rural to outlying or from outlying to suburban. Other changes reflect increasing complexity in population density as parks changed from a single designation, such as rural or suburban, to a mixed designation. See the Definitions section for population center definitions and Table B.1 for previous and updated population center designations by park. In the pages that follow, a series of tables and figures display visitor use data for calendar year 2021. By documenting these visits across the National Park System, the NPS Statistical Abstract offers a historical record of visitor use in parks and provides NPS staff and partners with a useful tool for effective management and planning. In 2021, 394 of 423 NPS units...
