Introduction of “Risk Based Maintenance” Method, and Usefulness and Problems in Case of Applying It to Ships and Offshore Facilities - Proposal for Optimized Ship Maintenance

Abstract

"Risk Based maintenance (RBM)" is a method to perform reasonable maintenance. The maintenance procedures and their interval are optimized based on the "Risk" calculated by PoF (Probability of Failure) and CoF (Consequence of Failure).RBM can perform the maintenance optimized safely and economically by using the CoF factor. Also, this is suitable for the long term management of facilities because this method is based on probability theory. RBM has already been known as a general method in Oil Refinery and Chemical Industry, and has a potential to optimize a maintenance of ships or offshore facilities.
