High strength steels are being used increasingly for construction of offshore platforms as they offer a significant weight saving compared to steels of lower strength. At present, steels with yield strengths in the range 550 to 690MPa are used for a variety of marine applications and 900MPa steel has been proposed for future jackups to operate in deep water. The aim of this review was to examine the published information available on the effects of sulphate reducing bacteria in the marine environment on hydrogen related damage in high strength structural steels.
