This article focuses on issues related to risk assessment when maneuvering a loaded bulk carrier in close proximity to a vessel performing underwater work at the time. It is based on a detailed analysis of an incident that took place in the Gulf of Gdansk. The write-up explains real turns of events, conditions and factors that contributed to the incident, but also its consequences are explained. Some other aspects of this article focuses on, are the processes of examination of the direct causes of the incident and identification not compliance with regulations, requirements, or procedures that help to find out the human, technical, and organizational errors. The authors of this text indicate the safety guards that have failed, give the reasons for their failure and, where it was possible, point out the safety guards that should or must be established. The article does not take into account theoretical models for the described accidents, but only practical aspects, human errors and applicable local and international laws and regulations. Particular attention was devoted to the analysis of human errors made by officers maneuvering the surface vessel in the close vicinity of divers performing underwater works.

The paper presents the use of the Fast-Time navigational simulator to verify the location of designed elements of navigational infrastructure in vicinity of a high traffic fairway. The aim of the study is to perform the analysis of navigational safety in vicinity of newly constructed quay placed to the east of the island Ostrow Brdowski. The Quay is intended handling of large steel structures. The Fast-Time simulation is performed to evaluate the safety of the navigation passage through the fairway along the quay for the future use of vessels which length may exceed 260 m. This kind of simulation method has been implemented to make a statistical analysis based on a large amount of data, the collection of which would be very expensive and time consuming using a Real-Time simulator.

W artykule przedstawione zostanie wykorzystanie symulatora nawigacyjnego typu Fast-Time w celu weryfikacji lokalizacji projektowanego nabrzeża w pobliżu uczęszczanego toru wodnego. Celem opracowania jest wykonanie analizy nawigacyjnej dla nowobudowanego nabrzeża na wschodniej części wyspy Ostrów Brdowski przeznaczonego do załadunku wielkogabarytowych konstrukcji stalowych. Zaprezentowano ocenę bezpieczeństwa nawigacyjnego przejścia przez tor wodny prowadzący wzdłuż nabrzeża, dla przyszłościowych jednostek o długości 260 m, wykonana metodą symulacyjną Fast-Time. W badaniu wykorzystano model czasu przyspieszonego ze względu na dużą ilość danych (przejazdów) potrzebnych do wykonania analizy statystycznej, użycie symulatora czasu rzeczywistego do uzyskania wystarczającej ilości danych byłoby zbyt drogie i zbyt kosztowne w czasie.

Abstract This article presents the underlying concepts of a mathematical model optimizing the routes of vessels carrying dangerous goods proceeding in the vicinity of passenger ferries. The method is based on the estimated risk of collision between a chemical tanker and a passenger vessel. Risk assessment was performed using three models. The first model determines the distance of the passing ships on the selected area on the basis of the AIS data. The second one is a stochastic model of navigational safety assessment, which provides statistical data on the probability of collision between the two chosen types of vessels. The third model determines the consequences of collisions between passenger ships and chemical tankers. The study defines the scope of the parameters affecting the objective function of vessel route optimization and their importance in the optimization problem.

An analysis of the failures occurring in the energetic systems of Polish fishing cutters, covering the years 1999–2012, is presented in this paper.The structural age, size and number of Polish fishing cutters is also indi- cated herein. The eff ect of the failures on the marine environment has been assessed, taking into consideration a presumed fuel spillage depending on fish catch volume and an analysis of the biodegradability of various fuels. The subject of the analysis also includes the damage impact of transponders cooperating with a vessel monitoring system (VMS) on an increase of the risk of collisions between other off shore industry objects and fishing vessels.

Zgodnie z zaleceniami IMO, jeżeli dane o obiekcie są dostępne zarówno z AIS jak i z radarowej automatycznej pomocy nakresowej (ARPA lub ATA) oraz kryteria łączenia danych są spełnione tak, że informacje z AIS i radarowe są traktowane jako dotyczące jednego obiektu fizycznego, to w urządzeniach radarowych, jako stan domyślny, powinny być automatycznie wybierane i wyświetlane tylko symbol AIS i dane alfanumeryczne AIS tego obiektu. Artykuł przedstawia przeprowadzone w warunkach rzeczywistych wstępne badania wiarygodności prezentowanej przez statkowy AIS informacji o odległości i czasie mijania z drugim statkiem wyposażonym też w AIS, poprzez porównanie danych z AIS z prezentowanymi przez ARPA.
EN
According to the IMO recommendation when the target data from AIS and radar plotting aids are both available and the association criteria are fulfilled such that the AIS and radar information are considered as for the one physical target, then as a default condition in radar equipment the AIS target symbol and the alphanumerical AIS target data should be automatically selected and displayed only. The article presents researches conducted in real conditions on the reliability of information presented by ship's AIS about the passing distance with other vessel equipped with AIS too and time to pass it by comparing data from the AIS with that presented by ARPA.

Rapidly increasing numbers of ships and ship sizes pose an ever-growing challenge to the maritime industry. Although statistics indicate improved levels of safety in the industry which carries 90% of the world’s trade, the risk of navigational accidents, among other issues, remains a prime concern and priority (EMSA, 2010; 2014). In order to address these concerns, the authors turned to another high-risk industry for inspiration. Specifically, they turned to the aviation industry, which has often been used as a source of comparisons and ideas by researchers in the maritime domain. Keeping up with the trend, the authors of this paper turn to a tried-and-tested system used widely in modern aviation: the Airborne Collision Avoidance System (ACAS). The prime idea behind ACAS is to construct two virtual 3D zones around an aircraft. These zones are dynamic, and depend on the manoeuvring characteristics of a given aircraft. If the system detects an “intruder” (another aircraft) in either of the two well-defined virtual zones, it provides warnings and/or instructions to pilots of both aircraft to take certain precautionary or emergency measures. In the current paper, the authors explore whether or not such a system is feasible for use in the maritime domain and, if so, how. The paper provides a detailed analysis of the potential benefits and drawbacks of using an ACAS-like system onboard vessels. It also discusses possible means of implementation and integration with current equipment, and explores how the introduction of e-navigation may impact the proposed solution.

This paper introduces and presents a strategy for ensuring safety during control of vessel inter-action in real time. A measure of danger during the interaction is explicitly computed, based on factors affect-ing the impact force during a potential collision between an object and the vessel. A motion strategy to mini-mize the danger factors and risk level is developed for articulated degree of freedom for multi activities of vessel. Simulations and experiments demonstrate the efficacy of this approach. The aim of this research is to introduce and develop an assistant system by analyzing ships activities in real time from land aspect.

Flexible strategy is the method, which allows forming a strategy of the operating vessel for avoiding collision, when navigating in congested waters and the risk of collision with more than one vessel exists. This strategy does not conflict with the ColReg requirements and take into account multi-variant approach of conduct of targets and possibility of worsening of situation in time. The methodological base for the solution of this problem is the theory of the dynamic n-guided systems.

In the present paper, a safety evaluation index that determines the probability of accident occurrence of collision and stranding when the experiment is executed using a ship handling simulator is proposed, by noting Unsafe Ship Handling Situations. The number of Unsafe Ship Handling Situation was counted from the results of simulator trials, and the accident ratio was surveyed from the past records of sea casualties in the corresponding water area. The correlation between the appearance ratio of Unsafe Ship Handling Situation and the accident ratio showed reasonable coincidence with the order of 10-3. When port administrator tries to assess the effectiveness of safety improvement planning of port and harbour facilities, it can be said that this kind of probabilistic prediction model of accident occurrence is indispensable from the aspect of introducing cost effectiveness analysis.

The marine environmental is one of human activity areas where risk is greater then average. Among water areas there are those where ship maneuvering is limited more then other sea areas. There are waters limited by port structures. The article presents methods of assessment of navigational risk as a combination of probability of ship collision to port structures and its consequences. The models of describing of accident probability are presented. Besides the result of ship port structure collision is determined by probability of structure collapse.
