Wreck of a ship is an incident that must be avoided. Ship accidents are generally caused by a several cases, such as human error, natural disaster, technical errors, missed communication, poor condition of the ship, and many more. Ship wreckage have huge impact for ship navigation, environment, economics, and others. Those impact have many disadvantages for the shipowners, and also for environment. For examples the fuel spills that pollute the environment, make disturbance to sailing ship because the track for those navigation is blocked by the ship wreck and their cargo especially on shallow location (<50 m). These research will discuss the effect the container when it is floats on the sea and its interference other ships. The main objective of this study is to present a risk assessment on the environmental impact of the wreck and container cargo. Wrecks on the seabed is likely to pose a risk to passing ships. container and its contents as well as the possibility of refloat, and also their environmental risks emanating from the wreck and container cargo, such as fuels, lubricants, and chemical cargo. Variations scenario is a collision between ships that pass by floating containers. The frequency of refloating container, and the consequences of the passing ship depends on several factors, which will be the subject of research. However, because of the frequency of refloating containers is unlikely, then the risk is low and does not pose a danger to navigation. These risk assessment using risk matrix 5x5 which is the combined value of the frequency and consequences of the incident. The results of this study indicate the level of risk, whether the risk is accepted, not accepted or received by considering the costs and benefits (ALARP). To consequence, there are two parameters which energy is absorbed and the penetration occurs. The absorbed energy is divided into two, namely the energy absorbed by ship and the energy absorbed by containers. In this study were taken 5 groups based on the size of the vessel. In this cases any 5 size group of vessels is based on the size of the ships that pass in the shipping lanes at the site of the sinking. Assumed these vessels have speed 10 knots at the location. As well as speed drifting containers having 0 to 3 knots.

W artykule przeanalizowano zalecenia dotyczące kryteriów oceny ryzyka dla prac w przemyśle off-shore wprowadzonych przez administracje państw mających największy udział w badaniach i wydobyciu morskich złóż naturalnych. Podano główne czynniki ryzyka dla obiektów prowadzących prace wydobywcze w warunkach morskich oraz metody jego określenia i przyjęte granice akceptacji. Wsparto się danymi statystycznymi zebranymi w ogólnoświatowej bazie danych sporządzonej przez Norweskie Towarzystwo Klasyfikacyjne DNV - Worldwide Offshore Accident Databank - WOAD obejmującej wypadki w sektorze off-shore od roku 1970 do 2014. W szczególności analizie poddane zostało ryzyko występujące na obszarach polskiej strefy ekonomicznej w związku z intensywnym rozwojem polskiego przemysłu badawczo wydobywczego.

The article presents the analyzes of the recommendations for the risk assessment criteria for the work in the off-shore industry introduced by the administrations of countries having the largest share in the research and production of marine natural resources. Given the major risk factors for facilities with production facilities in sea conditions and the method of its determination and the accepted limits of acceptance. Results were supported by the statistical data collected in a global database compiled by the Norwegian classification society DNV - Worldwide Offshore Accident Databank - WOAD covering events in the off-shore from 1970 to 2014. In particular, the analysis has been subjected to the risk occurring on areas of the Polish economic zone due to intensive research and development of the Polish sea mining industry.

The paper presents practical aspects of development of acceptable risk levels in maritime shipping with respect to the cooperation of parties involved in maritime safety, commonly used risk acceptance principles, criteria and uncertainties related to their development. The results of analysis of risk assessment methods used for potentially hazardous operations on board ships performed on the basis of extensive studies on the onboard safety management systems is presented. The merits and drawbacks of the approach used in the development of risk acceptance criteria in onboard safety management systems are discussed.

W artykule przedstawiono praktyczne aspekty wyznaczania dopuszczalnego poziomu ryzyka w żegludze morskiej, w odniesieniu do wzajemnych zależności stron zaangażowanych w obszarze bezpieczeństwa morskiego, ogólnie stosowanych zasad i kryteriów akceptowalności ryzyka oraz niepewności związanych z określaniem kryteriów akceptowalności. Na podstawie obszernych badań pokładowych systemów zarządzania bezpieczeństwem statku przeprowadzono analizę metod oceny ryzyka operacji stwarzających potencjalne zagrożenie dla statku i załogi. Omówiono wady i zalety podejścia stosowanego obecnie przy opracowywaniu kryteriów akceptowalności ryzyka w pokładowych systemach zarządzania bezpieczeństwem.
