Study of Main Propulsion Plant’s Mission Reliability in View of Performance Degradation

Abstract:

The reliability of watercraft depends to a large extent on the reliability of main propulsion plant. It should be distinguished on the base of mission variation charged by watercraft during study of main propulsion plant’s reliability. The mission reliability under rated and economical speed is studied via one main propulsion plant as subject in this paper, while the influence performance degradation of main propulsion plant on its mission reliability mostly studied. Relative curve between mission reliability and working time has been found. The results show that, reliability model in view of performance degradation has good expansibility, approach more to actual malfunction of main propulsion plant, as well as evaluates performance of main propulsion plant well and truly. The results could be guidance for user to establish maintenance schedule in order to improve the mission reliability of main propulsion plant.
