Protective Coatings Offshore: Introducing a Risk-Based Maintenance Management System—Part 1: Risk Analysis Methodology Available to Purchase

This paper summarizes the risk analysis methodology and challenges related to the establishment of a risk-based maintenance management system for protective coatings. Maintenance of protective coatings offshore is demanding on resources and costly. Initial selection of a coating system and the quality of the application work, including surface preparation, are vital elements for securing an acceptable coating lifetime. Most offshore installations will require, however, maintenance of the protective coatings due to degradation and/or mechanical damages. Development and implementation of a maintenance program for coatings is therefore an essential part of the overall maintenance program for these installations. A complete maintenance program development includes: 1) establishment of coating quality status through inspection, 2) preparation of a maintenance program/strategy, and 3) preparation of detailed maintenance plans and job packages/descriptions. Optimization of maintenance and inspection programs through risk analysis is used frequently by the industry today. This principle can also be used for coating maintenance. Since the risk picture can be described by scenario, frequencies, and consequences, risk could be expressed as a function of coating status and a consequence of a coating damage. Based on this assumption, a systematic approach for optimization of the maintenance program has been developed.
