INTRODUCTION

ABSTRACT

  • . Industrial accidents are often related to uncontrolled corrosion. An improved corrosion and integrity management program reduces the risk of unexpected accidents, and improves operational safety for the plant, personnel and the environment.

  • . A good corrosion and integrity management program will ensure that asset conditions are known, maintenance and repair strategies planned, and unplanned production stops avoided. As an example, assuming a profit of US$5 per barrel in a refinery, the lost profit for one additional day’s downtime for a 250,000 barrel/day capacity plant would amount to more than $1 million.

  • . Through corrosion monitoring and management, increased corrosion can be detected before damage is done, and the causes of corrosion can be identified. This allows efficient mitigation of corrosion, allowing for the increased service life of pipes, pipelines and process equipment. According to the Manager of the Mechanical Services Shops Department at Saudi Aramco, corrosion can affect the degradation of equipment and units by 4 to 5% life expectancy annually, 1 highlighting the importance of combatting corrosion and increasing equipment life.

  • . Corrosion and erosion management can contribute to increased productions and reduced operational costs. As an example, according to DNV GL, Statoil saved, GB£175 million per year at the Gullfaks field by being less conservative with respect to choking back wells through active sand monitoring. 2 Similarly, being able to tune in 1 % or 2% of low cost crude into the feed mix in a refinery can easily imply cost reductions of many million USD per year for an average size plant.
