Andrew Courtney explains how using engineered surface coatings can minimise corrosion and wear in the off shore sector
orrosion can be defi ned as the gradual destruction of materials by chemical reaction with their environment. According to the United States Cost of Corrosion
Study, produced by NACE International, a leading authority on corrosion engineering and control, corrosion costs the US oil and gas exploration and production industry US$1.4 billion a year. To put the cost of corrosion to the off shore industry in closer perspective, as far back as 2000, retrospective bolt preservation on each of its North Sea assets accounted for costs of between £150,000 and £250,000. For oil and gas producing operations, there is no escaping the challenge of

corrosion; steel is susceptible to corrosion and the harsher the environment, the more accelerated the corrosion process becomes. As off shore exploration moves into deeper and more hostile waters, so the potential impact of corrosion increases. T e greater diffi culty maintaining components in increasingly remote and challenging environments requires the need for extended component life. Components that have enhanced resistance to the eff ects of corrosion are now essential as they increase service life and reduce the need for costly maintenance. Developments within the industry, aimed at reducing off shore development costs, involve reduction in platform weight and increasing use
