Opis:
This paper is dedicated to an overview of components of an onboard control system of an autonomous ship. This system controls and operates the ship. Therefore, this system needs to be able to analyze the ship’s state, predict its future development and analyze the consequences of its own decisions. The paper focuses on software aspects of the onboard control system, not the hardware. The paper provides an overview of technologies that can be used to implement the components of such a system responsible for planning new routes, handling the ship during the voyage, ensuring its seaworthiness and safety during the voyage, monitoring an autonomous ship from an onshore control centre, ensuring the robustness of the onboard control system, and collective operations of multiple autonomous ships. The paper describes benefits the maritime industry would gain from deploying some of the technologies developed for autonomous ships on ordinary, human-controlled ships. The paper also describes some challenges, especially in the field of automatic decision and reasoning, arising from the emergence of autonomous and smart ships. The main contribution of the paper is that it summarizes existing research in different areas of autonomous ship technology.

Opis:
In this paper, a general framework for modelling stochastic service curves for communication networks is presented. It connects with each other two approaches to the traffic analysis and performance evaluation of communication systems, namely, the one which is called a deterministic network calculus with its stochastic counterpart. Thereby, it enables to treat any communication traffic in a consistent way. Further, as we show here, it enables also achieving new results. Derivation of the above model is presented in details in this paper. Finally, some hints are given how the method presented in this article could be applied in maritime telecommunications area.

Opis:
This paper presents the key assumptions and preliminary research on an integrated system called ESABALT, for enhancing maritime safety, which incorporates the latest technological advances in positioning, e-Navigation, Earth observation systems and multi-channel cooperative communications. The most novel part of the ESABALT concept, however, is a focus on user-driven crowdsourcing techniques for information gathering and integration. The system will consist of a situational awareness solution for real-time maritime traffic monitoring via utilizing various positioning technologies; an observation system of the marine environment relevant to transportation and accidents including assessing the sea ice, oil spread, waves, wind etc.; and a methodology for context-aware maritime communication with cooperative, multi-channel capabilities. The paper presents the intelligent, novel, user-driven solution and associated services developed in ESABALT for enhancing the maritime safety in the whole Baltic area.

Opis:
Nowadays shipping industry has problems such as reduction of mariners, aging of mariners, and labor expenses. To solve the problems, One Person Bridge Operation was developed as navigation supporting system. However, One Person Bridge Operation remained technological problems and one man error. Therefore, in this study, telexistence on a ship was proposed by using satellite communication. Telexistence on a ship is a concept of maneuvering between land and ship with at least two mariners such as navigation officer and helmsman. Navigation officer works on ship as usual and helmsman supports ship from land. In this paper, remote maneuvering system was developed as the first step of telexistence on a ship. For evaluating the effectiveness, ship experiment was carried out. From the result, navigation officer and helmsman could alter ship’s course to 20 degrees within 60 seconds and less than 5% overshoot in the proposed remote maneuvering system.

To ensure the safety of maritime transport the access to information must be provided through a commonly used services. However, an equally important task is to determine or agree on interpretation of incoming data and assessment of a current and predicted navigational situation and, in further step, intentions of the participants in the transport process. Thanks to the standardization of information format, automatic information exchange gets increasingly wider. Another step ahead is automatic interpretation of information and automation of negotiation processes - intelligent communication. Rapid development of IT and ICT technologies creates such opportunities. This article presents the results of research on a system of automatic communication and co-operation in maritime transport.

Opis:
The era of autonomous ships has already begun in maritime transport. The 30-year forecast for the development of marine technologies predicts many autonomous vessels at sea. This will necessitate radical implementation of new intelligent maritime navigation systems. One of the intelligent systems that has to be implemented is a collision avoidance system. The inference process is a key element of autonomous manoeuvres. These authors propose an inference process that enables exchange of information, intentions and expectations between autonomous vessels and gives them an opportunity to negotiate a safe manoeuvre satisfying all the parties concerned. The model of inference in the communication process has been presented. Methods and algorithms for information exchange and negotiation have been developed. These models were implemented and tested under various conditions. The results of case studies indicate that it is possible to effectively communicate and negotiate used the developed method. To demonstrate the effectiveness of the presented approach over 30 random simulations have been carried out. After successful laboratory tests, over 100 scenarios were executed in quasi-real conditions and fully operational conditions. Tests were carried out in the center of the Foundation for the Safety of Navigation and Environmental Protection on Lake Silm in Iława, Poland. In the framework of project AVAL (Autonomous Vessel with an Air Look) POIR.04.01.04-00-0025-16, 82 random scenarios involving four vessels were performed and 60 random scenarios with two vessels. In 2020 tests were carried out in real conditions on the ferries Wolin and m/f Gryf. The communication and negotiation system presented in the article has been designed and developed specially for maritime navigation purposes. The authors believe that the presented solution can be one of various solutions implemented in autonomous shipping in the near future.

Opis:
Objectives Good communication between seafarers and their families at home is essential to compensate for the work-related strain experienced on board ships. This paper presents the needs and possibilities for communication with home in seafaring. Material and Methods In total, 323 seafarers were interviewed during their work assignments on board (the participation rate of 88.5%). The results were stratified by cultural background, family ties, rank groups and shipping routes. Results The average stay of the officers on board the current vessels lasted 4 months and that of the ratings 9 months (p < 0.001). About a third of the officers and a half of the ratings evaluated these lengths of stay as too long. In the study, only 50 participants (15.5%) mentioned that the Internet on board their previous vessel was available for private use. Only 40.6% of these crew members stated that they had used it on a daily basis. Particularly the seafarers assigned to worldwide destinations and crew members without children experienced the insufficient possibilities for telecommunication as work-related strain (OR 1.87, 95% CI: 1.15–3.04 respective OR 2.00, 95% CI: 1.03–3.88). The average amount of time spent on telecommunication amounted to more than 2.5 h/week (which equals approximately 20 min/day). The average cost of about USD 30/week for telecommunication was considered by 24.7% of the seafarers as “much too high.” Conclusions The fact that several crew members considered the time spans of their assignments as too long should lead to certain adjustments. In view of the importance of good options for shipboard telecommunication, this study makes an essential contribution to understanding the crews’ needs. Measures should be taken to improve communication by allowing an easier access to information and communication technology (ICT) (on board and ashore), by offering cheaper fees, and by providing Internet access in their cabins. The study results show a substantial need to improve the means of communication on board ships. Int J Occup Med Environ Health. 2019;32(6):805–15

Opis:
In the process of ocean development, the technology for maritime communication system is a hot research field, of which information security is vital for the normal operation of the whole system, and that is also one of the difficulties in the research of maritime communication system. In this paper, a kind of maritime communication cryptographic SOC(system on chip) is introduced, and its compiler framework is put forward through analysis of working mode and problems faced by compiler front end. Then, a loop unrolling factor calculating algorithm based on queue theory, named UFBOQ (unrolling factor based on queue), is proposed to make parallel optimization in the compiler frontend with consideration of the instruction memory capacity limit. Finally, the scalar replacement method is used to optimize unrolled code to solve the memory access latency on the parallel computing efficiency, for continuous data storage characteristics of cryptographic algorithm. The UFBOQ algorithm and scalar replacement prove effective and appropriate, of which the effect achieves the linear speedup.

Morskie technologie informacyjne i komunikacyjne są zespołem wzajemnie powiązanych ze sobą dyscyplin nauk technologii, inżynierii oraz metod organizacji pracy kadry floty morskiej i rzecznej, zajmującej się zbieraniem, transformacją, przechowywaniem, transferem i wykorzystaniem informacji. Sieci komputerowe typu MANET powstają automatycznie oraz często bez systemu administracyjnego. Funkcje węzłów w tego typu sieciach mogą być realizowane zarówno przez routery, jak i hosty. Mogą one przesyłać pakiety danych do innych węzłów oraz wspomagać wykorzystanie aplikacji użytkownika. W artykule omówiono problemy, z jakimi sieci telekomunikacyjne muszą się zmierzyć w zakresie zwiększenia bezpieczeństwa w transporcie morskim oraz zaproponowano, w jaki sposób za pomocą konwergencji nauk matematycznych, informatycznych oraz technologii morskich można je rozwiązywać.
