This paper discusses the methodology and challenges related to the establishment of a risk based maintenance management system for protective coatings.

Maintenance of protective coatings offshore is resource demanding and costly. The initial selection of coating system and quality of the application work, including surface preparation, are vital elements in order to secure acceptable coating lifetime. Most offshore installations will, however, require maintenance of the protective coatings due to degradation and mechanical damages. Development and implementation of a maintenance programme for coatings is therefore an essential part of the overall maintenance scheme.

Optimisation of maintenance and inspection programmes through risk analysis is frequently used by the industry today. This principle can also be used for coating maintenance. As the risk picture can be described by 1) Scenario, 2) Frequencies, and 3) Consequences, for protective coatings, risk could be expressed as a function of coating status and consequence of a coating damage. Based on this assumption a systematic approach for optimisation of the maintenance programme has been developed.
