Résumé :
Ambient and indoor air pollution have high impact on public health. Safety of indoor air is crucial for well-being and stress tolerance of seafarers due to their prolonged stay in the environment characterized by adjacency of work and leisure premises. Flaws in ventilation and air distribution systems may lead to infiltration and accumulation of pollutants in air of living and recreation premises. However, available onboard HVAC systems designs are not fit to ensure cleanliness and quality of the indoor air of ships accommodation. In this study a new approach for indoor air quality management on board merchant ships is proposed. Air quality standards and requirements analyzed and formal representation formulated. Approximation techniques for thermal comfort index PMV reviewed and computationally efficient polynomial representation proposed. Unified dynamic model of microclimate, thermal comfort and gas composition of air is developed. Model performance was studied in simulation environment with superstructure microclimate model of a real ship. As a proof of the hypothesis a preliminary prototype developed and tested on board of gas carrier vessel. A proposed control optimization problem statement allows implementation of a wide range of indoor air quality and comfort management systems at scale. Prototype multiparameter controller based on microprocessor technology showed potential of performance improvement and scalability for development of distributed control systems.

Résumé :
The design of innovative metamaterials with robust and reliable performances is attracting increasing interest in shipbuilding, due to the potential and versatility of these materials. In particular, soundproofing is becoming an even more important characteristic, to ensure the comfort levels required by the standards on board ships. Thus, shipyards are constantly looking for innovative solutions to improve the insulation between environments, while respecting the safety regulations with which the materials on board must comply. In this study, an innovative solution called the Metasolution is designed and characterized, considering both the transmission loss (TL) and the fire resistance. The Metasolution is proven to be a valid substitute for the traditional honeycomb panels used on board for soundproofing. The TL of the innovative solution is increased, and the thickness is decreased, while maintaining the cost and the weight in line with the traditional solution. Moreover, the regulations regarding fire safety on board are satisfied.

Résumé :
Abstract The ship operability can be understood and analysed in different manners, and its quality is described using different indexes by different authors. Practically, there is no general and widely accepted description of total ship operability in the literature, nor in the rules of classification societies, which would include both seakeeping and manoeuvrability characteristics of a ship, and simultaneously take into account all ship subsystems and, what is most important, comfort and safety of people on board. The aim of this paper is to propose a general definition of total ship operability and name, adjust, describe and justify criteria which should be considered in the ship operability analysis, as well as to provide a relevant algorithm paving the road for further investigation on total ship operability determination.

Résumé :
In shipbuilding industry, comfort is a relevant issue both for crew members and passengers. A comfortable environment enables crew members to perform accurately their tasks and it is an effective factor contributing to the satisfaction of passengers. Noise and vibration, as environmental parameters, play an important role in subjects' comfort. Naval Classification Societies established series of noise/vibration comfort level criteria, which, however, did not take into account some aspects: 1) noise/vibration recordings are carried out during time periods shorter than the exposure time of passengers; 2) the subjective mood is not investigated. In the present study, we studied comfort perception by measuring heart rate variability and mood. We exposed participants to four levels of acoustic noise [from 45 to 55 dB(A)] and three levels of vibration (1.5, 1.8, 2 mm/s) inside a full-scale mock-up of a cruise ship cabin. We found that the increase of noise/vibration intensity determines an increase of heart rate variability and negative mood. However, changes in comfort responses did not occur for the noise/vibration comfort thresholds identified by the Classification Societies. Our results evidence the importance to include psychophysiological measure of comfort when defining comfort criteria on board.

During the springs and summers of 2009 to 2012, military and nongovernment organization nurses served side by side on hospital ships USNS Comfort and USNS Mercy to offer free humanitarian clinical services to developing nations in Central and South America and Southeast Asia. Translators were engaged to facilitate communication on shore and off. Host nation patients came on board for prearranged surgery and then were returned to land within a few days for follow-up care with local clinicians. Nurses had opportunities to go onshore to assist in clinics, teach as subject matter experts, or participate in construction/remodeling projects. Weather and other environmental conditions influenced the availability and services of the ships, which could also be deployed to provide support for global disaster relief. Professional and personal preparedness and flexibility were essential for operational effectiveness. The authors, both critical care nurses, learned many lessons in teamwork, education, and life at sea. Readers are encouraged to consider the challenges, hard work, and vast rewards of hospital ship service.

Résumé :
Purpose The Maritime Labour Convention (MLC) embodies standards of existing international maritime labour conventions and recommendations, as well as the fundamental principles to be found in other international labour conventions. The aim of the convention is to address the employment standards of seafarers in the areas of fair wages, contractual terms, working and living conditions, as well as their health and safety on board ships. The purpose of this paper is to provide an in-depth study of MLC Regulation 3.1, specifically on the layout design of the accommodation spaces and possible solutions to meet the new demands as those will certainly affect the crew comfort, health and well-being on board ships. Design/methodology/approach The approach used includes a review of pre- and post-MLC conventions and regulations. This is then followed by looking at the impact of MLC Regulation 3.1 on new ship design. Possible solutions for new ship design are then proposed. Findings The findings from the paper were as follows: More flexibility in the form of non-mandatory guidelines and substantial equivalence under MLC. Under MLC, only Special Purpose Ship (SPS) is allowed to accommodate four persons in one room. The requirement for increased height and floor spaces would result in increased gross register tons (GT) for post-MLC built vessels. Impact due to post-MLC requirements would be more unfavourable for the design of smaller vessels below 500 GT than of bigger vessels of up to less than 3,000 GT. Possible solutions include applying for exemptions and substantial equivalents with flag states or registering with a non-ratifying flag state. Originality/value This paper has been based on a dissertation carried out for the partial fulfilment of a post-graduate degree. It has not been published in any journal.

Résumé :
The design of a propulsion system for each ship must take into consideration a large number of factors. Some important factors that will lead to obtaining an efficient propulsion system are: the integration of a large number of elements in a functional space, selection of suitable components, the efficiency assessment taking into account functional safety and comfort criteria for crew and passengers. Considering the factors listed above, the analysis and design of the propulsion system for a chemical tank was performed. To choose the optimal components, the propulsion performance for this ship was analysed using 4 different engines. The operation of the propeller behind the ship has an effect on both the structure of the ship and the navigation conditions of the crew on board. Ttherefore, in the last part of the paper will be presented the effect of the operation of the propeller chosen for the chemical tank. In this sense, the surface forces induced by the propeller that appear in the stern vault will also be a center of interest in this work.

Résumé :
In this study, the product attributes of cruise tours are distinguished into on-board activities, leisure space, cabin comfort, Michelin restaurant, and refund mechanism, and the multi-attribute utility model of cruise tours is constructed using the choice experiment (CE) method. Of the 575 questionnaires distributed, 439 were valid, with an effective recovery rate of 76.3%. The results revealed the following: (1) when cruisers travel, what they value the most is the quality of service on board, followed by the facilities on board; (2) passengers’ preferences for comfortable pool space and more activities on board are negatively significant, indicating that they do not prefer to add these amenities and experiences to the cruise ship; (3) passengers are willing to pay extra to upgrade the interior cabin to one with a view and to experience the Michelin restaurant; and (4) influenced by the COVID-19 pandemic, cruisers are more willing to manage their own health. Moreover, the pandemic does not reduce their willingness to travel by cruise.

Résumé :
The design of ships or any other floating systems intended to operate on or close to the surface of the sea is controlled to a large extent by what is usually referred to as seakeeping, or, in more common terminology, safety at sea. This is a primary consideration and criteria, which has to be fully met. Safety of a ship naturally includes the crew, cargo and the hull itself. Seakeeping is, indeed, a generalized term and reflects the ship's capability to survive all hazards at sea such as collision, grounding, fire, as well as heavy-weather effects related to the environment in general and waves in particular. The two most likely types of failure under these conditions are due to structural causes and capsizing resulting from insufficient stability under severe weather conditions. Such criteria as economical navigation of the ship as related to speed-keeping abilities, fuel consumption, avoidance of damage to ship components and cargo, and comfort to crew or passengers, or both, are key items. The operational limits of electronic equipment, mechanical components and weapon systems on board warships are other aspects of sea keeping. In this work it is highlighted that seakeeping is a generalized term that includes a wide variety of subjects such as ship motions (amplitudes, accelerations, phases), deck wetness, slamming, steering in waves, added resistance, hydrodynamic loadings (pressures, forces, moments) and transient loads. Since the ship environmental operability or its sea keeping characteristics are closely linked to the severity of the sea, the description of the seaway is usually considered as an integral part of sea keeping. It is taken into consideration that the severity of the sea cannot be considered in absolute terms, since for each floating system, be it a ship, a platform or a buoy, the intensity of the sea state can only be determined in terms of the system's responses. Hence, different thresholds apply to different problems, and sea state 4 may be just as severe for a small patrol craft as sea state 8 may be for a larger containership. Hence, the characteristics and frequency of occurrence of waves in specific sea zones are required if a possible reduction in the system environmental operability is expected. It is demonstrated that most texts or papers, which deal with the overall question of sea keeping, devote some attention to the basic phenomena, that is, the seaway and the motions of the ship or other floating platforms as a result of the excitation imposed by the seaway. Ship motions, as such, do not always constitute the criteria for sea keeping, and much more often other responses directly related to the magnitude and phasing of the motions or the resulting velocities and accelerations constitute the prime cause for exhibiting good or bad sea keeping qualities. Such responses could be a function of the motion only, as in the case of added resistance or hydrodynamic pressures, or they could be a function of motion and other design parameters, such as freeboard in the case of deck wetness or the longitudinal weight distribution in the case of vertical bending moments. In this work, latest methods of modeling and computation for body-wave interactions described and compared with data observed for container carrier. The foregoing calculation routine Судноводіння | Shipping & Navigation ISSN 2306-5761 | 2618-0073 30-2020 Національний університет «Одеська морська академія» 79 is fairly well accepted today among naval architects specializing in the sea keeping aspects of the ship design process. Differences between the results obtained by various techniques as presented by the available computer programs are insignificant. However, since the regular-wave results are of little or no value except as input for the more realistic long- and short-term response predictions in a real seaway environment, it is important to determine which wave data information and what statistical extrapolation techniques are used to obtain the latter. The format used to describe the seaway in most ship response calculations is the wave spectrum. However, since measured spectrum for a specific sea zone or route are very rarely available, it is often necessary to use spectrum measured in one location for predictions in another location. In such a case, while the basic spectruml shape and scatter remain unchanged, the percentage of wave height distribution would vary to represent realistic conditions for the sea area in question. Such data usually are based on observations, and assuming the sample is large enough the distribution of expected wave heights should be quite reliable. An alternative approach often used in ship design is to utilize one of several theoretical spectruml formulations [2, 3, 4] such as the Pierson-Moskowitz one-parameter spectrum, the ISSC spectrum, the JONSWAP spectrum, and other. In each of these cases, some input parameters are required usually in the form of wave height, period, peak frequency, fetch, etc. The reliability of the wave data depends in these cases both on the quality of the input parameter and the adequacy of the theoretical formulation.

Résumé :
It was in July 1956 when the senior writer of this paper was requested to prepare a program for investigations and studies required in connection with the proposed deep-draft channel from the Gulf of Mexico to Point Comfort. During 1938 to 19^0, the senior writer had attempted to analyze the available field and model study data which were then available on Galveston Bay in the hope of thus being able to reduce the shoaling in the various deep draft channels in Galveston Bay. In 19^0, the senior writer had been in charge of two field parties one of which measured the flow of water in the Colorado River and the Gulf Intracoastal Waterway near their crossing near Matagorda, Texas. A peak discharge of about 80,000 cubic feet per second was measured in the Colorado River at the Palacios Road bridge, about 15 miles upstream from its mouth during this period. At that time there were no locks nor gates in the Intracoastal Waterway adjacent to the Colorado River. It was found then that about one third of this peak river discharge flowed southwest through the Intracoastal Waterway. On the basis of the above experience and the information obtained from a review of the Matagorda Ship Channel, Texas, project report (l) and other literature, then, available (2) thru (5) a program was formulated in June 1958 and submitted to the Division Engineer in Dallas with the request that the Office of the Chief of Engineers, the Southwestern Division Engineer Office, the Beach Erosion Board and the Committee on Tidal Hydraulics review the program.

Résumé :
The international tourism competition poses new challenges to the cruise sector, such as the achievement of the tourists’ satisfaction and the increase in on board comfort. Moreover, the growing sophistication of tourists’ needs leads to a more user-centric touristic offer. Consequently, a personalized cabin environment, which fits the users’ activities and their characteristics, could be a plus value during the cruise vacation. These topics, however, are strictly connected with the diffusion of digital technologies and dynamics, which represent the tools to achieve the goal of a customized on-cruise experience. This paper presents E-Cabin, a novel Internet of Things (IoT) framework architecture that has at its core a reasoning system tuned on data gathered from the environment and from each specific passenger and the activities he/she performs. The framework leverages on knowledge representation with ontologies and consists of a publisher–subscriber communication framework that allows all of the IoT applications to use the reasoner and the provided ontologies. The paper demonstrates the proposed system in a demo cruise cabin where, by using the E-Cabin application, it is possible to set various atmospheres based on the users and activities occurring in the cabin.

The authors discuss the structure and efficacy of the U.S. Navy’s response to COVID-19 and evaluate the utility of this endeavor, with the objective of providing future recommendations for managing worldwide healthcare and medical operational demands from the perspective of Navy Neurosurgery. Materials and Methods The authors present an extensive review of topics and objectively highlight the efforts of U.S. Navy Neurosurgery as it pertains to the humanitarian mission during the COVID-19 pandemic. Results During the humanitarian mission (March 27, 2020–April 14, 2020), the response of active duty and reserve neurosurgeons in the U.S. Navy was robust. Neurosurgical coverage was present on board the U.S. Navy Ships Mercy and Comfort, with additional neurosurgical deployment to New York City for intensive care unit management and coverage. Conclusions The U.S. Navy neurosurgical response to the COVID-19 pandemic was swift and altruistic. Although neurosurgical pathologies were limited among the presenting patients, readiness and manpower continue to be strong influences within the Armed Forces. The COVID-19 response demonstrates that neurosurgical assets can be rapidly mobilized and deployed in support of wartime, domestic, and global humanitarian crises to augment both trauma and critical care capabilities.

In order to achieve the acoustic comfort design for ship accommodation areas, This paper introduces the noise prediction of ship’s superstructure cabins based on boundary element method (BEM). The study investigates the ship acoustic responses due to fluctuating forces induced as a result of interaction between a 4-bladed propeller and Bulk Carrier ship 35,000DWT at full scale. The mathematical models for the ship and the propeller have been built and validated using computational fluid dynamics (CFD), then unsteady simulation done to obtain the transient responses of the propeller excitations. Finally, the acoustic responses of ship super structure under propeller excitations are predicted using BEM in time domain. This work shows a numerical method enable to measure the structural and acoustic responses of the ship at propeller rotating speeds. In addition, at the structural resonating modes of the propeller and the ship. As the propulsion system is the main source of the ship exciting forces thereby nowadays prediction of the ship low frequency noise due to propulsion system becomes important to naval designer for designing a comfort accommodation areas for the crew onboard the ship.

Abstract The US Navy hospital ship USNS Comfort played an integral role in the initial phases of Operation Unified Response–Haiti following the devastating earthquake that struck near Port-Au-Prince, Haiti, on January 12, 2010. Deployed to Haiti from its home in Baltimore, Maryland, just 4 days after the earthquake, the USNS Comfort would become the region's primary tertiary casualty receiving center for 6 weeks. The pathology and laboratory department staff onboard the ship helped support the mission and experienced unique mass casualty/disaster relief scenarios while underway. This article reviews the accounts of the core laboratory, microbiology, anatomic pathology, and blood bank divisions on the USNS Comfort from the chaotic first few weeks to the final patient discharge 40 days after Operation Unified Response–Haiti began.

Ship indoor environments are related with comfort conditions and health risk problems. As a consequence, to obtain an adequate heating, ventilation, and air conditioning (HVAC) system, a redesign of the engine control room must be made. To answer this problem, an analysis of real thermal comfort conditions was carried out and a new air conditioning procedure is proposed. From the obtained results it can be concluded that comfort conditions in the bridge and dining room are close to neutral, while the most extreme conditions have been found in the engine room.

Résumé :
The focus of this work is to simulate and optimize thermal comfort in a ship air-conditioning system by evaluating the performance of different types of air supply outlets. Thermal comfort analyses were performed in Solidworks Flow Simulation software by changing the number, type and position of air supply outlets and the comfort was optimized by evaluating the values of temperature, velocity, PMV (Predicted mean vote) & PPD (Predicted Percentage Dissatisfied). It was concluded from the results obtained from different analyses that air supply outlet is a vital part in any type of HVAC (Heating ventilation & air conditioning) system design, as its number, type and position has significant effect on the air distribution and thermal comfort in a subject space. It was also deduced that improper selection of air supply outlet can result in room air stagnation, unacceptable temperature gradients, and undesirable velocities in the occupied zone that may lead to occupant discomfort. Through this work the importance and effectiveness of CFD (computational fluid dynamics) design tools, in the design & optimization of HVAC systems has been evaluated and it was concluded that CFD design software like Solidworks flow simulation provide an excellent provision to validate different aspects of HVAC design before actual construction.

Résumé :
A cruise ship is a concentrate of technologies aimed at providing passengers with the best leisure experience. As tourism in the cruise sector increases, ship owners turned their attention towards novel Internet of things solutions able, from one hand, to provide passengers with personalized and comfortable new services and, from the other hand, to enable energy saving behaviors and a smart management of the vessel equipment. This paper introduces the E-Cabin system, a software architecture that leverages sensor networks and reasoning techniques and allows a customized cabin indoor comfort. The E-Cabin architecture is scalable and easily extendible; sensor networks can be added or removed, rules can be added to/changed in the reasoner software, and new services can be supported based on the analysis of the collected data, without altering the system architecture. The system also allows the ship manager to monitor each cabin status though a simple and intuitive dashboard, thus providing useful insights enabling a smart scheduling of maintenance activities, energy saving, and security issues detection. This work delves into the E-Cabin’s system architecture and provides some usability tests to measure the dashboard’s efficacy.

Résumé :
Abstract. How do people respond when their group’s power is threatened? Four studies suggest that threats to group power lead people to adhere to and invest in their group. When a personally important group’s power was threatened, people psychologically adhered to the group (Studies 1a and 1b). This adherence occurred among people who were high (but not low) in group identification (Study 2). Adherence to the group was associated with behaviors aimed at promoting benefits to the group (Study 3). Findings suggest that people invest themselves in personally important groups when the group’s power is threatened. This occurs largely among people strongly identified with a group, suggesting that clinging to the group occurs especially when costs to leaving are high.

Résumé :
In recent years, the waterway navigation and transportation industry has been developing rapidly, and the living environment of ship cabins has not received much attention. Using questionnaire surveys, data collection and computer simulations, this study explored the problems and causes related to thermal comfort that affect a crew living onboard. The survey showed differences in the thermal sensations of the crew. Cabins below the deck of a ship are usually more comfortable than those above deck. These differences were related to the range of frequent activities undertaken in the cabins. The data and calculations show that the thermal comfort in the stern winch cabin and the engine cabin was significantly higher than in the top living cabin and the meeting cabin. For cabins without windows in winter, the PMV and PPD indexes of those below deck were on average 11.95% higher and 7.03% lower, respectively, than those above deck, indicating better overall thermal comfort below deck. The simulation showed that the simulated PMV of an occupied cabin was up to 17.55% higher than the actual PMV, indicating that the number of crew members in the cabin significantly affected its level of thermal comfort. The results provide a reference for understanding and improving the thermal environment of ships and temporary water facilities.

This study aims to investigate sea transportation in the new normalera in Bombana Regency, especially at Kasipute Port. This studyincludes the number of ships operated, the number of passengersdeparted and arrived at Kasipute Port, and analyzing the serviceperformance of the Kasipute Port before and during the new normalera. The research method was carried out by collecting secondarydata as data recapitulation of ships operated and the volume ofpassengers departed and arrived at the Kasipute Port at the Office ofthe Bombana Regency Harbormaster then primary data was get byinterviewed passengers (respondents) and filling out questionnaires.It carried service quality analysis using Importance PerformanceAnalysis (IPA).The results showed that during the new normal era, the number ofships operated experienced the highest decline reaching 58% in May2020. Meanwhile, the largest percentage decrease of passengersduring the new normal era was 85% for departed passengers and77% for passengers arrived at Kasipute port in May 2020. Thedecline in the number of ships and passengers that occurred duringthe new normal era was partly due to the PSBB imposed by theBombana Regency Government since April 2020, so it limited themovement of people using the marine transportation mode. Basedon the results of the service quality analysis, the priority factors inimproving service performance before the new normal era atKasipute Port are the comfort of the ship (E1), cleanliness of the ship(C2), and the time of departure of the ship (D1), while the priorityfactors in improving service performance during the new normal erais the provision of masks by the port (E3), ship cleanliness (C2), shipdeparture time (D1) and ship comfort (E1).

Résumé :
Oscillatory vertical motions of ships cause seasickness. There is a mathematical model that can be used to compute the percent of passengers who will get sick caused by vertical motions. However, the application of the mathematical model requires obtaining 2 hours of records of experimental or simulated ship motion data. Based on a filters analogy, this article proposes a new frequency-domain method for the calculation of seasickness incidence. The method can be applied to any sea power spectrum and any ship. Because it is based on response amplitude operators or transfer functions, which can be obtained with seakeeping simulation programs, the method can be applied even before the ship is built. The results of the method can be useful for ship design and for the analysis of best operation for passenger comfort.

Résumé :
ABSTRACTObjective: The Haitian earthquake of January 12, 2010, was a disaster essentially unprecedented in the Western Hemisphere's recorded history. The USNS Comfort departed from Baltimore, Maryland, within 72 hours of the earthquake and arrived in Port-au-Prince harbor on January 19. During the subsequent 40 days, the ship provided one of the largest relief efforts in the US Navy's history.Methods: The data analyzed included all patients evaluated and treated by the USNS Comfort between January 19 and February 27, 2010. A medical chart with a unique identifier was created for each patient on admission. A patient database was created from these records and used for this analysis.Results: A total of 872 patients and 185 patient escorts were processed aboard the ship. Ages ranged from younger than 1 day to 89 years: 635 were adults and 237 were children. Of those admitted, 817 of the patients were admitted for longer than 24 hours; the average length of stay was 8.0 days. The need for surgery was substantial: 454 patients went to the operating room (OR) 843 times for 927 cumulative procedures. A total of 58 patients underwent amputations.Conclusions: Haiti was almost completely reliant on foreign medical teams for trauma care. Analysis of the data illustrates the challenges of triage and treatment in a humanitarian mass-casualty response. The remarkable coordination and cooperation among the Haitian Ministry of Health, nongovernmental humanitarian aid organizations, and the US military highlighted the responders' respective capabilities and demonstrated the importance of collaboration in future disaster response efforts.(Disaster Med Public Health Preparedness. 2012;6:370–377)

Résumé :
The choice of optimal shape of ship hull surface is one of the main problems of ship architects and designs. A choice of the form is based on empirical formulae or on intuition of designers. In the article a method of determination of explicit algebraic equations of theoretical shape of ship hull with three main cross-sections given in advance and coinciding with the design waterline, the midship section, and with the main buttock line is given. The forms of the lines in the main cross-sections are chosen from conditions taken in advance. These surfaces are called hydrodynamic. A method is illustrated for three threes of main cross-sections of the ship hulls, i.e. nine hydrodynamic surfaces were constructed. All algebraic equations were converted to parametrical form for comfort of computer modelling. With their help, all nine ship surfaces proposed for the introduction were visualized. Having changed constants containing in the surface equations, i.e. correcting the forms of three main geometric parameters of ship hull, one can select the most rational shape of hull surface for the first approach. Further, it is possible to begin planning parallel middle bodies or to combine bow and stern extremities of a ship from different fragments of algebraic surfaces but with the same midship sections. In a paper, only geometrical problems of design of theoretical hull shape are described.

Résumé :
Abstract The ship will produce various swaying motions after being affected by wind, waves and other disturbing factors when sailing. among which the transverse swaying motion is the most violent. By the effective control of transverse swaying motion it can improve the safety of ship sailing and the comfort of crew. Thus, in the present study, ship anti roll slider device is chosen as the research subject, and a theoretical analysis on the principle of rocking reduction of ship anti roll slider device is performed. For the problem that the PID controller parameters do not have self-tuning capability, the PID controller parameters are optimized by introducing the PSO algorithm, and the PSO-PID controller is designed on this basis. The PID controller and PSO-PID controller are used to simulate the ship anti roll slider device on Matlab. and the simulation results show that the PSO-PID controller has good rocking reduction effect under different sea conditions, which verifies the effectiveness and superiority of the PSO-PID controller.

Résumé :
Due to large quantities of cargo transported by oil carriers, as well as the inability of many ports to accommodate such ships, the solution was found in the application of STS (Ship-to-Ship) operation. Opposite, LNG STS terminals are usually set up where the construction of a classic onshore terminal is impossible or economically unprofitable. However, such an operation is associated with increased risks which could be minimized by taking precautions, following the regulations, and having well trained officers and crew on board. Well trained and competent crews are indispensable in STS procedures to minimize the risks to which STS processes are exposed, especially those that can threaten the environment. This paper elaborates LNG STS procedure and discusses the necessity for appropriate training of seafarers involved in such operations. Furthermore, it proposes education requirements for officers involved in LNG STS procedures based on relevant recommendations, practices, and perceived shortcomings.

Résumé :
Traffic calming devices on urban streets, such as elevated pedestrian crossings, speed bumps and roundabouts, are increasingly used, raising a real problem in relation to the on-board comfort that passengers perceive. To measure vibrational comfort related to traffic calming devices that passengers of the public transport perceive, an acquisition system called ASGCM (Autonomous System for Geo-referenced Comfort Measurements) has been developed, taking as a reference the European regulations on rail transports. ASGCM permits to link each measurement of vibration, ground velocity and acceleration with geographical information resulting from a GPS. In this way a map of a comfort index, statistical surveys and correlation between on-board comfort and traffic calming, can be directly obtained by any Geographic Information System (GIS), able to query a centralized remote database, which was developed ad- hoc. A large number of experimental tests has been performed to define a vibrational comfort index and to collect a large dataset that allows statistically significant comparisons between different infrastructures and their characterization. The proposed technique can also be useful for diagnostics purposes, such as vehicle comparison and road maintenance state monitoring.

Résumé :
AbstractThe design of the ship cabin layout is a multi-objective comprehensive optimization problem, which needs to consider the location of the passage, cabin layout, space utilization ratio, functional realization, comfort, safety, and so on. In this paper, an improved tabu-criterion genetic algorithm for the intelligent design of ship cabin layout is proposed. According to the characteristics of ship accommodation cabin layout design, a ship deck layout area model and a multi-objective optimization model including relative location model, absolute location model, and ergonomic constraint model are established. The neighborhood transformation criterion and tabu-criterion of tabu search algorithm are introduced into genetic algorithm to advance the local search ability of a genetic algorithm. At the same time, a new genetic algorithm coding method is proposed to avoid the generation of illegal solutions in cabin layout sequence crossover and mutation operation. The improved genetic algorithm can effectively improve the local search ability of a genetic algorithm and make the algorithm converge to the optimal solution as soon as possible at the later stage of calculation. Finally, the simulation results verify the feasibility and efficiency of the proposed intelligent design method for ship accommodation cabin layout.
