  • Corrosion protection for mooring and riser elements of a tension leg platform
    Patent number: 4619557
    Abstract: A flame sprayed aluminum coating of high strength steel components offers excellent seawater corrosion protection, increased fatigue life and uniform low level cathodic protection that avoids hydrogen embrittlement. Marine mooring and riser elements fabricated from such components are superior in the above respects to steel components protected from corrosion by common sacrificial anode cathodic protection systems. In addition, the need of welding a stud to the steel to insure electrical continuity between the steel and the sacrificial anodes is eliminated.
