Interrogating In-Service Performance

摘要

Turbocharger defects top a list of 43 potential fault categories as the leading cause of failure on low speed two-stroke engines. In 1991 classification society Lloyd's Register (LR) launched a new ship division database with enhanced capabilities for studying machinery defects. The system can be used to identify the machinery type (population) at risk, determine the period each component of the population had been at risk, find the appropriate defects attached to each component and calculate the defect rate in terms of the number of faults which can occur on one ship in 10 years, or 10 ships in one year.
