Offshore steel structures are subjected to severe corrosive environment, thus it is important to apply reliable corrosion protection methods. In recent years, the expected life of structures is extended, therefore the evaluation of the life cycle cost has become a growing interest. A new reliable and economical metallic sheathing for protection of offshore steel structures has been developed made of seawater-resistant stainless steel YUS270 (20Cr-18Ni-6Mo-0.2N, low carbon). The seawater resistance stainless steel sheets are welded to the structures using an indirect seam welding method. Compared to conventional metallic sheathings, this welding method reduces the material and fabrication costs. The experimental results of the stainless steel sheathing indicate good corrosion resistance in seawater, good impact resistance and good fatigue properties. The sheathing described is a corrosion protection method for minimizing life cycle costs of long service life structures whereby low initial costs and low maintenance costs are realized.
