Risk-based coating maintenance: an integrated program

Abstract

The integration of a cost-effective coating management plan into an asset integrity system is essential in ensuring asset longevity. The success of any corrosion management program relies on condition monitoring and quality auditing. Monitoring activities also contribute to maintenance plan feedback ensuring continuous improvement in corrosion management activities. It is recognised that there are many ways to organise and operate successful corrosion management programs, each of which is asset specific and depends on factors such as: Design. Stage in the life cycle. Process conditions. Operational history. AGR defines corrosion management as: “…the part of the overall management system that is concerned with the development, implementation, review and maintenance of the corrosion policy.” AGR corrosion management programs use a combination of risk-based Inspection technologies and traditional restorative maintenance activities. SOLVTM, a unique product from AGR Field Operations, is used for the management of fabric maintenance (surface coatings, insulation, passive fire protection, pipe and cable penetrations).Long-term plans: 5-year plans or longer based on client requirements. Prioritising areas and recommended maintenance intervals. Cost estimates and scope of work. Estimated condition development. Application: Treatment of component surfaces (coatings). Passive fire protection. Quality control. The benefits of the SOLVTM concept can be summarised as: Information regarding condition of maintenance objects. Preparation of fixed price maintenance plan and workpacks. Condition control through survey and audit. Cost control via quantified scope. Maintenance budget inputs for 5-year plan. Documented cost savings of 20–50 % have been realised where SOLVTM has been introduced and been used for long-term corrosion management.
