Abstract:

This report documents a reliability study of large 1,600 tons and over commercial vessel engine room automation systems. The total effort involved conducting a literature search on maritime automation and reliability topics, analyzing the engine room automations systems on two steam vessels and one diesel vessel, conducting a criticality evaluation, preparing reliability- related design and performance criteria, and evaluating reliability aspects of preventative maintenance. For the vessels evaluated, Failure Modes and Effect Analyses FMEAs were conducted and fault trees developed. Reliability predictions were computed at several levels of hardware grouping. The criticality impact of potential failure effects was investigated in terms of time constraints and failure detection provisions. A number of recommendations are offered for improving the reliability of current and future engine room automation systems.
