Opis:
Obiekty budowane dla prowadzenia morskich operacji górniczych narażone są na liczne zagrożenia. Największe zagrożenie dla tych konstrukcji stanowi falowanie morskie. W czasie silnych sztormów pojawiają się od czasu do czasu fale o niezwykle dużej wysokości i ogromnej sile niszczącej, określane jako fale monstrualne. W artykule przedstawiono szereg przypadków pojawiania się takich bardzo rzadko występujących fal oraz opisano warunki dla ich powstawania a także ich podstawowe charakterystyki. Przy projektowaniu obiektów oceanotechnicznych posadowionych na dnie morza a także obiektów pływających związanych z operacjami górniczymi niezbędne jest uwzględnienie możliwości pojawienia się fali monstrualnej, której uderzenie obiekty te muszą przetrzymać.
Offshore structures designer for deep sea mining operations Or prone to many different hazards. The most import ant hazards are from the sea waves. During violent storm huge waves possessing extremely high devastating force appear from time to time. Such waves are called freak waves or rogue waves. The paper described several case of meeting such very rare waves by ships. It described also conditions that are necessary to their appearance and their basic characteristics. Because offshore structure must withstand devastating force of such a wave, the possibility of meeting it should be taken into account in the design process of those structures.

Officially, at the end of 2019, a correction of the Baltic Sea Location was published in the Sailing News, which at the same time informed about the change of the operator of the Polish GMDSS Responsibility Zone, excluding Witowo Radio so far and transferring the Polish Rescue Radio (SPL) service. Starting from 2020. PSL began operational service of GMDSS in Poland. This article is the first presentation of the experience from the implementation of this project “Construction of maritime communication system in danger, GMDSS-PL”. mainly focusing on the OpenEye_ GMDSS operating system. In addition to the technological layer of the project, the procedural and organizational part of the GMDSS service has been equally important. The maritime emergency response system can be compared to the operation of 112 on land. The operation and efficiency of this system directly translates into human health and life as well as the quality of the marine environment around us. The technical means provide a high quality and certainty of business continuity. Communication in danger is one of the basic and most important tasks of the Polish maritime service. At this point, all operators and GMDSS services in the Maritime Office in Gdynia and Szczecin deserve praise.

Opis:
Simulators are useful in very wide field of current life. Very important is to know their advantages and disadvantages. One of the most important of navigational simulator using is deck officers training. Possibilities of using real collision situations for officers training can seriously improve knowledge about deck officers behavior in dangerous situations. Analysis of the possibility of using the NMS-90 simulator for ship's collision reconstruction was the aim of experiment. Some problems of recorded data accuracy and simulator possibilities influence on accident reconstruction process are described in this paper.
Symulatory są obecnie szeroko wykorzystywane w wielu dziedzinach życia. W związku z tym bardzo istotną kwestią jest znajomość zarówno ich wad, jak i zalet. Jedną z dziedzin, w których wykorzystuje się symulatory nawigacyjne, jest szkolenie oficerów pokładowych. Wykorzystanie w trakcie symulacji sytuacji nawigacyjnych, w których doszło do kolizji statków, powinno znacząco wpłynąć na poznanie sposobu zachowania się nawigatorów, jak i przebiegu procesu podejmowania przez nich decyzji w trudnych sytuacjach nawigacyjnych. Istotą przeprowadzonego w symulatorze eksperymentu było sprawdzenie możliwości wykorzystania symulatora NMS-90 do rekonstrukcji wypadków morskich. W artykule przedstawione zostały wybrane problemy związane z wpływem dokładności zarejestrowanych danych źródłowych oraz możliwości samego symulatora, związanych z dokładnością rekonstrukcji sytuacji kolizyjnych.

Opis:
Gospodarka morska jest w szczególny sposób narażona na niebezpieczeństwo ze względu na środowisko swojej działalności. Zagrożenia te wynikają zarówno z działań umyślnych, jak i przypadkowych (warunki hydrometeorologiczne, mechaniczne itp.). Są to zagrożenia zależne i niezależne od człowieka np. środowiskowe, bezpieczeństwo zdrowia i życia ludzi, czy mienia. Pomimo podejmowania prób ograniczania ryzyka niebezpieczeństwa, niemożliwe jest jego całkowite wyeliminowanie. Pomocne mogą być wszelkiego rodzaju systemy bezpieczeństwa, alarmowe, ratunkowe, oraz działania legislacyjne i edukacyjne armatorów i załóg statków do działań obronnych. W artykule przedstawiono wybrane aspekty bezpieczeństwa transportu w basenie morza Bałtyckiego oraz podjęto próbę analizy stanu bezpieczeństwa na tym akwenie.
The maritime economy is particularly exposed to danger due to the environment of its operations. These risks result from deliberate actions, as well as incidental (hydrometeorological conditions, mechanical, etc.). These are the threat dependent and independent of human eg. environmental, safety health and life of humans or belongings. In spite of attempts to limit the risk of danger, it is impossible to completely eliminate it. May be helpful here all kinds of security systems, alarm, emergency, legislative and educational of ship owners and crews to the defense activities. The article presents some aspects of the state of transportation safety in the Baltic Sea Basin as well as undertaken the attempt to analyze the security state of this sea area.

Opis:
The Strait of Istanbul, 17 nautical miles long, is one of the main routes of international maritime trade. Connecting the Black Sea countries with other countries of the world, the Strait is the second busiest waterway in the world in terms of international ship traffic. In addition to busy sea traffic, limited geographical conditions also make it difficult to navigational safety. The Strait of Istanbul is the only chokepoint that stands out with the risk of maritime accidents on the primary routes of world maritime trade. This situation poses a risk for both the transiting ships and the city of Istanbul, which has a dense population around it. Some of the accidents that took place in the recent history have caused worldwide concern due to the environmental pollution they cause. Considering the advantages provided by the developing shipbuilding technology and today load capacity of the ships, a disaster that will occur in a possible accident today will cause much greater destruction than in the past. In this direction, it has become a necessity to examine the accident profile in the strait in order to develop effective accident prevention measures and to strengthen the level of navigational safety in the region. In this study, maritime accidents that occurred in the Strait of Istanbul over a 16-year period were discussed in terms of their types and the response time of tugboats to a possible accident was examined.

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:
International transport is a subject to many regulatory measures worked out by governments, international organisations (e.g. IMO, ILO, EU), regional institutions and public entities. As a result, such regulatory mechanism, which is getting throughout international, strongly affects the real sphere of maritime transport as well as its productivity and efficiency. Maritime transport operators have to apply to many new standards and rules set by international public regulators aimed mainly at improving and enhancing safety and security at sea. It is sometimes very painful process in terms of costs and time but inevitable to survive in the highly competitive environment. The author analyses the nowadays existing regulatory mechanism in maritime transport and tries to evaluate it in terms of its impact on effectiveness of maritime transport processes.

Opis:
This paper explores concerns regarding the design, implementation, and management of alarms in DP vessels that, while in operation, need an incredibly high level of accuracy along with high reliability and safe operations. The Human, Technological, and Organizational factors (HTO) method is primarily used as analysis tool to find weaknesses in alarm handling during DP operations. The research focuses on results collected from Dynamic Positioning Operators (DPO) and instructors. Findings from the survey are presented and compared to the results from past accidents and technical requirements from Petroleum Safety Agency Norway via YA 711. Three accidents from past are referred to picturize the findings from the survey results. Furthermore, the conclusion is given with recommendations reflecting the findings from the survey. The main findings are an urgency to establish a centralized marine accident investigation system which enforces learning and recommendation to make operations safer. In addition, the survey also suggests that prohibition of clients or limiting their access to the bridge is necessary. Manufacturers could focus on research and development of alarm prioritization, on structuring and presentation, and profiting by taking feedback from end-users to make DP operations safer.

Opis:
Over the years, many publications have been published on planning ship’s passage through the NSR and input and output data modeling. Results were not considered in terms of errors of modeled output data. Basic research for the years 2008 - 2020 was carried out in the study on opening and closing dates of ice-free transit corridor on the NSR and probable number of tariff zones where paid assistance of icebreakers would be required. Mathematical relationships of average values and probable errors of navigational, ecological and economic ship voyage performance were developed. For this purpose, partial derivatives of functions were used. The outcomes of the study have shown that changes of total average cost of vessel’s transit voyage depends mostly on number of tariff zones where assistance of icebreakers is required. But navigation with icebreakers assistance ensures smaller standard deviation of total voyage time and thus more precise scheduling of ship's voyage timetable through the NSR. The higher probability of meeting requirements set by decision-maker when planning a long-term voyage of ship, the shorter time window for meeting these requirements. Outside the favorable time window, the navigational, ecological and economic results of voyage deteriorate very quickly.
