Opis:
The recent rapid improvement of nautical equipment functionality allows one to better observe and predict the dangers related to seamanship. However, these new features come with added complexity, and large amounts of information can overwhelm vessel crews and fleet operation centers, and the current state-of-the-art tools cannot filter out only the most important data for a given time and location. This paper presents the concepts and the algorithms of a software suite that provides a user with problem-oriented advice about a particular risk endangering a vessel and its crew. Based on the calculated navigational dangers and their predicted development, actionable guidance is proposed in an easy-to-understand human language. The quality of good seamanship is improved by a holistic approach to vessel installation, automated fleet operation center priority queuing, and the evaluation of crew performance during simulator training and daily operations. Both the software user interface, as well as the insights provided by the algorithm, are discussed.

Opis:
This paper presents theoretical model for fire hazard analysis in fuel oil and diesel oil systems in engine rooms. The model is based on the probabilistic calculus and covers a 'fire tree' and formulas to calculate fire frequencies. Preliminary assumptions and initial frequencies calculation parameters have been adopted on the basis of statistical data. Fire sources identification involves selection of definite number of system elements, the damages of which may result in flammable liquid leakage and self-ignition. Such elements as, inter alia, pipelines joints and sections, valves and system equipment, are taken into consideration. With the use of the model, it is possible to calculate individual fire frequencies for individual self-ignition sources, and synthetic risk in systems and specific rooms. The calculations account for a possibility of introducing construction changes of safety equipment that influence the risk, e.g. number of detectors, fire extinguishing nozzles (fire extinguishers), leakage protection, etc. The method can be used to analyze the influence of fire construction protection on the risk (so-called 'risk sensitivity' testing) in the phase of creating requirements. However, for its quantitative verification statistical data concerning engine rooms fire hazard is essential. It may be assumed that creating an adequate calculation model for the purpose of a general fire hazard analysis of an engine room (of a vessel) is a significantly bigger challenge.

Opis:
The paper presents the statistic data analysis of total losses of the fishing vessels. The emphasis is put on the total losses caused by the insufficient stability of considered ships. The research is focused on the fishing vessels, which are relatively small ones in marine industry, so they are most affected by the wind and rough sea. The correlation between type of the vessel, its size, the shape of its hull and the capsizing statistic is presented. The regularities noticed in course of statistic analysis allows to formulate the suggestions regarding the influence of some hydrodynamic phenomena on the safety of fishing vessels and the number on their total losses at the sea.

Opis:
Reviving is noticeable in the field of oil and gas production located under the seabed. The off-shore projects are being implemented. Due to this, the risk of accidents at each stage of production should be considered continually. The offshore market, both oil and gas as well as renewable energy, is estimated to increase steadily in the coming years. Therefore, the operations on the production oil field must be suitably protected at every stage of performing work. The paper describes how important Job Safety Analyses are for proper operations. The main aim of the article is to indicate steps and the best way of performing JSA on board of the offshore installation to reduce the risk of emergency. The selected disasters and major accidents indicate that the conducted activity is exposed to the risk of hazards to the natural environment and to people at every stage of the reservoir exploitation. The authors use the analysis of available international reports, the experience gained while working on different types of the offshore vessels and installations as well as in the Polish offshore company.

Opis:
Safe two-way vessel traffic may have some limitations. Fairway width, vessel dimensions, weather conditions, traffic density and other factors must be considered crucial and constraining safe passage of the vessel. The possible sea traffic regulation made by a Vessel Traffic Service (VTS) shore centre, is often based on criteria included in harbour regulations. This may not always be an optimum solution. This paper presents a concept and elements of a method for assessment of safe two-way traffic, based on experts' (pilots') knowledge and experience. The goal is to support the decision making process in a VTS centre. For this purpose tools of knowledge acquisition and representation as well as tools of statistical inference are used. The method is based on the results of the expert research which was performed with the participation of pilots who handle vessels on the Świnoujście-Szczecin fairway.

Opis:
This paper presents the process of quantitative assessment of selected factors influencing the probability of grounding. All grounding accidents that occurred during one year (2013) in the Baltic Sea area were analysed. The research area was chosen because of very high traffic intensity and a large number of narrow passages that make it difficult for navigation. The research period was limited by the latest data reported by HELCOM up to the year 2013. The Method of Grounding Probability Coefficient (GPC) calculation is proposed to reach the assumed goal. Either internal factors such as the ships size and ship type or external factors such as time of day, wind force and season were taken into account. As a result the values of coefficients describing the impact of various factors on the probability are evaluated. This coefficients, taking into consideration coupling effect, can be used in future in the navigational safety simulation models based on the assumed value of accident probability.

Opis:
Climate change provides for improved conditions for maritime navigation and results in increased activity in the Arctic. Those increased activities influence the safety at sea and risk of accidents. A disaster as the Costa Concordia incident would have far more serious consequences in Greenlandic waters than it had in Italy, therefore the question of prevention and disaster-preparedness is crucial. One approach to avoid risks is to create specific legislation. The legal system guiding safe navigation of cruise ships in/around Greenlandic waters is complex: the legal regime for navigation is set in different general and specific international, regional and national legal acts, partly non-binding, therefore issues of effectiveness arise. Safety is also influenced by practical issues, e.g. the lack of sufficient nautical charts for Greenlandic waters and “preparedness” at land to handle potential disasters, such as the SAR-system and preparedness of different actors, for example hospitals.

Opis:
Safety and efficiency of fishing fleet activity depend largely on the quality of management decisions. Cause-and-effect relationships of accidents involving fishing vessels were identified by means of an analysis of emergencies and fishing incidents. The suggested method of risks calculation is based on the use of statistical methods, fuzzy sets/expert estimations method and the probability theory. The following most common tasks are presented and solved: - there is an impact of two or more independent negative factors/events on the vessel such as failure of a sonar, a vessel operator error, another vessel operator error. - a transport vessel carries out loading and unloading of fishing vessels under different environmental conditions. The value of the risk of an emergency incident is determined. - the fishing vessel navigation performs under various meteorological conditions. A priori probability of incident-free operation is calculated according to expert estimations.

Pilotage is considered as the most critical leg of navigation and a complex operation in maritime domain. In this paper, we argue that Distributed Situation Awareness (DSA) is an important construct in pilotage as the information required to carry out operations is distributed between agents and artefacts. We identify the central themes from the theory of DSA which are useful in describing modern day complex socio-technical systems. Further, based on the central themes, we propose guidelines for evaluating bridge teams involved in pilotage operations.

This article aims to investigate the contemporary challenges of electronic navigation and assess the appropriate amendments should autonomous vessel technology becomes widespread in the near future. Vessel control systems and maritime communication are essential and sending and receiving alarm signals is critical to contemporary ship navigation. Numerous location and shipping information systems, such as GPS, Loran-C, and Decca, have arisen in recent decades to improve navigational safety. Other systems, including VHF and Inmarsat, have been developed to enhance the efficiency of maritime communication on board and to transmit risk and safety-related data. Additionally, safe navigation requires systems like Navtex, EGS, DSC, Epirb, and others [1].

The publication presents the structure of the agent system, tasked with control of the formation of unmanned port tugboats capable of performing pilot and towing services. The use of autonomous tugboats with installed software was presented with respect to the existing regulations related to Resolution MSC.467 developed by the Maritime Safety Committee (MSC) belonging to the International Maritime Organization (IMO), which creates guidelines for the definition and harmonization of the structure and format of maritime services in the context of e-navigation. The use of a multi-agent system structure enables synergistic cooperation of tugboats carrying out joint port operations, such as: assistance in maneuvers of ships, precision movement of ships and other objects in port areas, monitoring and patrolling of port areas, carrying out ice operations, carrying out inspections of quays, the possibility of assistance in liquidation of petroleum and similar pollutant spills. The paper presents the structure of the agent system and the description of possible scenarios of port operations. The control algorithms and the applied methods of artificial intelligence, such as evolutionary algorithms with elements of fuzzy logic, were discussed. The recorded traffic parameters from the actions carried out in the simulator of the marine navigation environment were presented.
