Abstract
The subject of this study is the equipment of the marine power plant of autonomous vessels. The degree of readiness of a modern marine power plant for use on autonomous vessels is considered from the point of view of its high degree of reliability. The paper demonstrates the capabilities of the method for constructing a table of operational risk indices and a redundancy risk index using the example of an average vessel intended for coastal shipping in European waters. Based on the presented sample of power plant elements, the operational risk index and the redundancy risk index for the marine equipment are analyzed, and an analysis of the reasons for their importance is given. The main engine and its elements, torque transmission mechanism, auxiliary engines and generator sets, fuel, lubrication, cooling water supply systems, and the air starting system are discussed as examples. In addition, the steering gear and the exhaust system are considered, and the redundancy risk indices (RRRI) are given for the selected equipment. After identifying the weak links of the considered installations, solutions for overcoming the risks that arise are proposed. It is noted that these solutions depend directly on the weak link and may consist of several options. Examples include redundant tuning, searching for alternative ship machinery elements with a lower risk index, or considering actions that allow a certain part to be fully operational. The paper attempts to find a solution for each element of the sample with a highrisk level (RRRI equal to 8, 9, or 10) when components are considered for improving reliability. Components with an average RRRI value of 6 or 7 are also considered. In this case, the implementation of alternative methods for forming a propulsion complex, for example, based on the known principles of electric propulsion, is noted as highly attractive as a way to overcome a large number of problems. It is concluded that no solutions are possible without a comprehensive analysis of financial viability. The conclusions drawn from the results reflect the possible direction of work on the creation of a marine power plant for equipping autonomous vessels.
