Industrial implementation of risk based inspection planning lessons learnt from experience: (1) the case of FPSO'S

This paper is the first part of a report dealing with industrial implementation of Risk Based Inspection planning methods to offshore facilities. The first part deals with FPSO/FSO while the second deals with fixed steel offshore structures. The objective of the report is to convey "lessons learned" from experience using RBI methods. Theses methods aim at establishing inspection planning based on optimization procedures derived from specific risk assessments. Experience of the three authors is based on the last methodological developments in the area of RBI planning for structural components subject to fatigue degradation and on application of these methods to various types of offshore facilities. The main steps of the RBI methodology are summarized in the first paper. General conclusions related to the two types of facilities are given at the end of the second paper.
