Metallic sheathing for protection of steel in seawater
A review of 37 years of experience with metallic sheathing to protect the splash and tidal zones of structural steel in seawater is presented. Variations in the corrosivity of the environment from zone to zone on a vertical structure and the interdependence among them are discussed. Corrosion-resistant alloys for sheathing include Monel (NiCu) Alloy 400, copper-nickel alloys, and stainless steel. The advantages and disadvantages of these noble alloys are compared with those of other protective materials such as paint coatings, concrete, polymers, and steel itself. Adequate protection of hot risers is critical and quite easily provided through proper design and sheathing attachment. The use of 90:10 copper-nickel Alloy C70600 is gaining visibility with progressive technology to provide biofouling control as well as corrosion protection.
