This combination of protective coating and cathodic protection is used on virtually all immersed or buried carbon steel structures, with the exception of offshore petroleum-production platforms and reinforced-concrete structures. Offshore platforms are usually uncoated...

... become the preferred sacrificial anodes for offshore platform cathodic protection. This preference is because aluminum anodes demonstrate reliable long-term performance when compared with magnesium, which might be consumed before the platform has served its useful life. Aluminum also has better current...

... (SCC) ( Ref 15 ). Oxygen is also responsible for the external corrosion of offshore platforms and drilling rigs. In oil and gas production, highly stressed structural members are directly exposed to a corrosive, aerated seawater environment. This also makes localized corrosion and corrosion fatigue...

... on the need to heat treat a welded structure. Indeed, it should be noted that stress relief of welded joints is never fully effective. Residual stresses up to yield point have been measured in stress-relieved pressure vessels and in up to 75% of yield in stress-relieved nodes in offshore structures. Due...
