DEVELOPMENT OF A DIESEL ENGINE RELIABILITY DATABASE (DEREL) FOR THE U.S. COAST GUARD

摘要

The Coast Guard currently determines when a diesel engine should be overhauled based on the results of the Diesel Engine Monitoring Program, Navy Oil Analysis Progra, Full Power Trials, and especially engine operating hours. In an effort to reduce costs, the Coast Guard is considering shifting their preventative maintenance to a condition-based system to reduce labor and downtime. To accomplish this goal, an analysis of the criteria used to indicate when a diesel engine should be overhauled must be performed. Before any statistical analysis can be conducted, and extensive amount of data must be collected on main diesel engines. This paper addresses the problem of creating a computer database to collect engine failure data for the USCG. We have conducted a review of several current shipboard reliability databases along with a look at modern developments in this area.
