Field experience has demonstrated the synergism between cathodic protection and organic coatings for providing long term corrosion protection to submerged offshore structures. This concept of coated steel with cathodic protection (CP) has been used by offshore oil producers to achieve weight and cost savings on offshore structures. For structures in deepwater, the weight savings are significant. Also, in areas where cathodic protection design requirements are not well established, the coating/CP system offers special advantages. Conoco's experience with coating/CP systems in the Gulf of Mexico and the North Sea is presented along with planned future use of this corrosion control system.
