ABSTRACT

The global electric power industry is evolving at a rapid pace, using innovative technologies and tools to meet critical challenges involved in generating, transmitting, and distributing high- quality energy to an increasing number of consumers. These challenges include enhancing system reliability and performance, maximizing asset life, and reducing both operation and maintenance (O&M), as well as capital costs. Corrosion prevention is key to the power industry's ability to achieve these goals and ensure safe and reliable performance while minimizing expenses. Whereas the technology exists to control corrosion, this may involve significant costs including expensive materials and designs, inspection programs, and proactively maintaining and/or repairing susceptible areas. This paper describes a corrosion management system approach that delivers cost-effective corrosion controls by incorporating corrosion management into a company's existing management systems. This approach will improve communication, resourcing, and funding allocation such that corrosion control investments result in positive returns while minimizing costly failures. Integrating such an approach with existing management systems insures the program's viability and sustainability in both corrosion control and financial performance.

Introduction

The electric power industry boasts a varied, distributed, and aged infrastructure to meet the needs of residents, manufacturing, municipalities, and emergency services. Corrosion and asset integrity management is a big part of design, operating, and maintenance strategies for this infrastructure, but its challenges vary between generation, transmission, and distribution facilities and components. This paper presents overall approaches to developing those strategies so that owners, operators, service providers, consultants, and others in the industry can build or improve risk management, cost performance, and customer value within their own areas of influence.

The value of improving asset integrity management strategies and execution will be realized by minimizing unplanned outages, which result from untimely equipment failures on transmission towers, piping, tanks, vessels, and other components. This would result in the reduction of maintenance costs for inspection, repair, and corrosion control, such that defensible spending forecasts for maintenance or replacement can be developed, and a sustainable programmatic framework to insure long-term delivery of these benefits can be built without detracting from other core business objectives. Each stakeholder and market will be able to determine just which recommendations and approaches from this paper fit best in their current responsibilities, markets, and climates.
