Opis:
An attempt of the specification of main issues, such as the objectives, tasks, activities, etc. which are being solved and are being done while the ship is conducted at sea is undertaken in the paper. These issues constitute the substance of the ship’s navigation process and all its sub process. The authors’ belief is that the specification of these issues would enable the better understanding the matter of ship’s navigation process. It could also facilitate the preparation of more precise algorithms of all navigation sub processes, i.e. even those which hardly could be expressed by the means of mathematical relations.

Opis:
Social responsibility in museums is not an entirely new domain. For many years now activities locating museums among the institutions contributing to creating better social reality have been observed. This new paradigm overcomes the stereotypical perception of cultural institutions as organizations taking care only of tangible and intangible testimony to the past of mankind, at the same time imposing on them the responsibility versus society and the community. The National Maritime Museum (NMM) in Gdansk tries to face these challenges not only by implementing educational and conservation projects, but also by supporting the development of the very Museum and its branches, at the same time directing its activities towards engaging in important social issues, such as eradicating accessibility barriers to heritage facilities, care for the environment, and sustainable development. Among the most recent accomplishments described in the paper let us mention the projects implemented during the COVID-19 pandemic, such as the new visiting format presented on the ‘Dar Pomorza’ Museum Ship. On 11 May 2021, NMM shared with the public the so-called Interactive Spherical Video integrated with modern Oculus goggles, introducing the spectator into interactive augmented reality allowing to become acquainted with the sailing ship from a new perspective, accessible to visitors with impaired mobility. A similar solution, though amidst a different landscape, was proposed in the lobby of the Museum’s main building on Ołowianka Island in Gdansk. Without getting aboard the ‘Sołdek’ Museum Ship, we can peep into its cargo hold and engine room. Furthermore, the paper describes many interesting educational or advertising undertakings which attempt at facing contemporary social challenges.

Opis:
The current worldwide research on atmospheric pollution caused by emission of toxic compounds from marine engines is based on a simplified input data. Existing databases of emission of toxic compounds in exhaust gases of vessels navigating in various parts of the world could not be used to estimate the emissions in the meso and micro scale such as the Baltic Sea or the Bay of Gdansk, because it leads to over-generalization of emission indicators, mainly due to lack of required detailed traffic characteristics. The article presents the methodology of identifying the marine engine load to determine the indicators and characteristics of the emission of toxic compounds in the exhaust gases from tankers navigating to the Liquid Fuel Terminal in Gdansk. Course of action presented for modelling the characteristics of toxic emission of marine Diesel engines of main propulsion. It the range of indispensable analytic works will be describe to defining on basis on ships' resistor profiles, the profiles of load, helical, speed of navigation based on the parameters of movement ship gain over with system AIS.

Opis:
Seafarers working in the 21st century global shipping industry are multi-national crew of migrant contract labourers, recruited by crewing agencies to work on a variety of ships for specific periods of time. Types of ships found today may include bulk carriers, container ships, tankers, gas carriers, heavy lift vessels, car carriers, ferries and passenger ships such as luxury cruise liners, among others. The voyages undertaken on board ships cover an expansive global maritime environment depending on where the goods are sourced, the destination, goods being transported, the type of ship, and if there are any designated ports of call for loading and offloading goods as well as boarding and disembarking passengers on the way. Typically, the greater proportion of the seafarers’ contract period is spent at sea, working in a maritime work environment on board different ships where he is assigned by his employer. During this time, crew interact with colleagues from a variety of nationalities, performing role-specific tasks in the same built environment and within a maritime mobile workspace. While conducting an empirical research on ship crew in the international fleet to harness their views on how maritime piracy in Eastern Africa may be affecting their health and wellbeing, the author observed that the ripple effects of structural changes in the shipping industry in the last few decades could be adversely influencing the seafarer work environment and social interactions, in ways that justify the description by Lane and Smith (2011) of ‘ships as jails’. The author has analysed the social adjustments that seafarers constantly make in order to fit into their evolving mobile workplaces. This discussion has been done using ideas espoused form Goffman’s ‘Total Institutions’ conceptual framework. This article therefore seeks to discuss the acculturation process that crew undergo within their mobile work built environment, as being comparable to some extent, to the social adjustments that Goffman’s subjects underwent in their institutions. Through ‘mortification processes’, the residents in Goffman’s studies were impacted psychologically by the regimented social life in the enclosed institution spaces interacting within limited social circles. Although a number of aspects have been identified that have the potential to adversely affect seafaring occupational health and safety regime (Walters, Bailey, 2013), this article will concentrate on highlighting some factors within the seafarers work place that in the author’s opinion, have directly influenced some psychological adjustments that seafarers make, in order to adapt the seafaring culture befitting their workplace. Three noteworthy influential factors discussed in this article include(a) the cumulative effect of living and working in an enclosed built environment (b) the seafarers’ limited social circle while onboard ships (c) the physical and social isolation of seafarers from colleagues while on-board ships, and from their families and land-based communities by the ship structure and the geographical maritime nature of their workplace. These features were selected as they could be discussed from Goffman’s theoretical framework as possible influences on the seafarers’ workplace socialization process. They are just a few comparable factors between the situation of modern seafarers and Goffman’s subjects. The scope of this paper will explore the potential for these three key factors to impact on psychological adjustments that seafarers make during their career working on ships. The author has based the discussion of ‘Ships as Total Institutions’ on the fact that there exists evidence of the cumulative effect of each of these three factors over time in the career of seafarers. The empirical studies provide the evidence upon which the author concludes that the ship is a ‘Total Institution’. This article has been written as the drafting of the author’s thesis is at an advanced stage. The intention of this paper is not prescriptive, rather as a catalyst for discussion of seafarers’ work environment and occupational health and safety from an additional social theoretical perspectives.

Opis:
In recent years, there has been an intensification of work on the autonomy of means of transport, which also applies to ships. Modern ships are already equipped with crew decision support systems and numerous diagnostic systems. Increasingly more systems are installed on ships that can operate without human integration. This situation leads to the development and use of fully autonomous ships. This overview publication briefly describes the main features of the construction and operation of autonomous ships, including some examples of structures already demonstrated in recent years. In summary, the author presents comments that provide a contribution to the discussion on the autonomy of means of maritime transport.

Opis:
Ship noise is a most important part of the field of underwater acoustics. Its reduction and monitoring is an important aspect in the performance of underwater acoustic systems and in the habitability of the vessel for the crew and passengers. In naval operations the noise radiated by a ship is also dominant source of information for underwater sonar systems. Sound intensity is the vector quantity which informs us about the sound power flux, the position and the direction of the sound source. The probe tracks the position of source and at the same time, measures the component of sound-intensity vector. Generally only one component of vector sound intensity was measured, perpendicular to a given measurement surface. The sound intensity of a moving source includes effects such as flow noise that are not present when the source is stationary. The accuracy of measuring acoustic intensity using two closely spaced hydrophones by correcting the phase mismatch error by measuring the transfer function between the two detector systems was examined. The two measuring hydrophone instrumentation systems were earlier calibrated. Our results have been obtained using digital methods, where was used PULSE measuring system.

This paper analyzes the requirements of the information transmission network of ship integrated condition monitoring system, and proposes a design scheme of ship condition monitoring system based on wireless ad hoc network. The wireless ad hoc network protocol was designed, its networking process was analyzed in detail, and the network transmission performance of the monitoring system was tested. The results proved the feasibility of the system. The above solution can be used for the transmission of ship state information that satisfies the requirements of wireless transmission, and has important theoretical and practical significance. The slot allocation algorithm has been receiving extensive attention as an important part of the TDMA system research. This paper analyzes the summarization and summarization of TDMA time slot assignment algorithms from several aspects such as slot synchronization, existing slot allocation algorithm, and slot assignment model, laying an important foundation for researchers to do further research. In the TDMA system, time is divided into non-overlapping time frames, and the time frames are divided into non-overlapping time slots. Each node in the network performs corresponding operations in each time slot.

Opis:
In recalculation of a model resistance into a real object resistance, one of difficult to estimate values is the shape coefficient. There are well known and tested methods of determining the (1+ko) coefficient for sea-going ships. In the case of inland vessels navigating in the limited depth waterways the problem has not been solved completely. The paper presents results of computations of the inland vessel shape coefficient determined by means of numerical methods (MOS). The shape coefficient has been calculated as a function of the block coefficient and block coefficient of the forebody of a barge hull. The calculations were based on five typical shapes of the transport inland vessels and were carried out for different depth to draught (h/T) ratios and different sailing speeds.

Opis:
This paper typically applied the concept of ranking by inspection using the dwell time of ships in five African ports to evaluate the variations in ship turnaround time and relative efficiency level. This is to identify the active factors that cause port congestion in African ports. The results provided some explanations on the consequences arising from these on notable African logistics and supply chain networks. The findings reveal that the bane of congestion in African ports emanates entirely from either planning, regulation, capacity, efficiency or a combination of these. The regression analysis with IBM SPSS v20 reveals that there is a significant relationship between cargo throughput and other port performance indicators in Nigeria for the study period (2005 - 2014). More so, the t-test reveals that there is a significant relationship between cargo throughput and berth occupancy rate which is significantly indicative of port congestion. This paper therefore recommends that African ports should enhance their regulatory mechanisms, and also improve capacity and efficiency level in order to shoulder the ever increasing challenges of port congestion in years ahead.
