Offshore oil and gas platforms are subjected to hostile, corrosive, marine environments and require continuous preventive maintenance to ensure prolonged and safe operation. Corrosion is identified as it occurs: above water, in the splash zone, and subsea. Coating systems, surface preparation, application, and maintenance are discussed for abovewater corrosion prevention. The advantages and limitations of added metal for corrosion allowance, corrosion-resistant cladding, and coatings are discussed for splash-zone corrosion prevention. Major emphasis is on the use of cathodic protection (CP) to prevent subsea corrosion. Included in the discussion are the advantages and limitations of sacrificial-anode and impressed-current CP systems for use with steel and reinforced concrete structures. Subsea monitoring and the effects of platform CP on well casings are also discussed.
