This article reports on how additional cathodic protection requirements on Shell Offshore Inc.'s Cognac platform in the Gulf of Mexico have led to the development of a unique anode carrying member for deepwater anode placement. The need for additional anodes was determined after extensive monitoring indicated a reduction of corrosion protection below 300 ft. at Cognac, especially in the well conductor bays. Each anode carrying member is between 75 to 90 ft. long with a 0.375-in. pipe wall and an OD of 18 in. The member is lowered to a depth of about 90 ft. before a diver is required for hookup.
