Corrosion fatigue related problems

In the same years, the exploitation of North Sea oil fields began, where, unlike the Gulf of Mexico, slight ocean is normal, so that the problems related to corrosion fatigue caused, in 1965, the sinking of the Sea Gem platform and the death of 13 workers. 

Other mechanisms, such as adhesive wear and corrosive wear, are considered to be less important in this problem and are not explicitly included in the analysis. The wear is related to the contact stress, deformation, surface coverage of particle and fatigue resistance, each of which is determined and expressed in terms of the material.
