EN The object of interest is to solve the problem of risk management of marine systems. But the main trouble is a lack of numerous and sure data on the reliability of the components of such systems. The methods based on the fuzzy logic seem to be helpful here. The goal of the article is to check the ef[...]

EN In the article the risk criterion for sea-going ships arising from the operation of the main engines’ crankshaft – connecting rod – piston systems is proposed. This criterion is based on the procedures recommended in the Formal Safety Assessment method developed under the auspices of International M[...]

EN The rules of classification societies require the use of redundancy in the systems essential for the safety of the ship. Duplication of pumps in the main engine auxiliary systems like cooling water system, lubricating oil system, fuel oil system is a good example here. Therefore, in the author’s opi[...]

PL W artykule wyszczególniono wybrane zanieczyszczenia uwalniane ze statków. Przedyskutowano krótko norweską propozycję indeksacji środowiskowej statków. Zaproponowano probabilistyczny model do oceny ryzyka stwarzanego przez statki względem środowiska morskiego. Model ten ma charakter strategii liniowe[...]
EN In the article selected polluting emissions and discharges from ships are listed. The Norwegian idea of environmental indexing of ships is shortly discussed. The probabilistic model of environmental risk of ships is proposed. This is a linear strategy model. The risk measure associates probabilities[...]

EN Gathering reliability data is quite difficult. Potential sources of such data are: reliability guides and handbooks, data collecting during operation of technical devices, expert judgments. Practice shows that very often the statistical sample we have to our disposal is small and non – homogenous. T[...]

EN In the paper a probabilistic model of environmental risk of ship power plant is presented. This is a linear strategy model with an additional restraint. It can be usedfor assessing risk to marine environment, which results from ship power plant operation. The risk is a sum of component probabilities[...]

EN In the article an approach to the problem of estimating time to the critical degradation of ship pipelines is considered. Such an assessment would consist of six stages. The fundamental idea is to include to the estimation of time to failure of pipelines such elements like: materials that the pipeli[...]

EN In the article an approach to the problem of estimating reliability data based on physical models is proposed. The possibility of reliability assessment for selected elements of ship pipelines, based on the recognition of the destructive physical phenomena taking place in them, is discussed. To do t[...]

PL W artykule przedstawiono rozważania dotyczące modyfikacji klasycznej siłowni okrętowej, polegającej na zastąpieniu jednego z zespołów prądotwórczych baterią akumulatorów. Miałoby to ograniczyć zużycie kosztownego paliwa odsiarczonego w obszarach chronionych. Podczas żeglugi poza obszarem chronionym [...]
