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 opinion, some attention should be paid to this issue. Two important questions arise here. Does duplication of pumps in marine systems make sense? What impact does the use of redundancy on the reliability of the system? To answer these questions, it is necessary to adequately assess the reliability of subsystems with redundancy. But it is not so simple. The first problem is gathering the reliability data. The second problem is the so-called human factor. The third problem, widely discussed in this article, is to adopt the appropriate reliability model.
