Reliability Trends, Operating Issues and Acceptance Criteria related to Exhaust Gas Turbochargers used in the Marine Industry -A Classification Society View

摘要

Lloyd's Register is a leading international classification society with the objectives of enhancing its clients' quality, safety, environmental and business performance. In support of these objectives Lloyd's Register maintains technical Rules and regulations for the classification of ships and installed machinery, including engines and their exhaust gas turbochargers. This paper provides a current perspective of a classification society on exhaust gas turbochargers used in the marine industry from the view points of: 1. Rule requirements and issues relating to turbocharger response during engine load variations stemming from governor testing and the operation of electrical/propulsion systems 2. the most recurring in-service faults and their incidence statistics over the past decade for exhaust gas turbochargers 3. failure investigation cases related to turbocharger burst containment.
