Shell develops unique anode system
Abstract
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.
