Retrofit cathodic protection maintains subsea asset integrity ///

Preventing corrosion on subsea architecture is critical for operators in their effort to maintain an asset’s integrity and extend field life. Cathodic protection (CP) is a cost-effective solution for the prevention of corrosion as part of a long-term integrity management strategy. When a CP system reaches the end of its design life, a retrofit system is often required to ensure an asset’s integrity is not compromised. Stork Technical Services UK Ltd recently engineered and supplied a custom-designed retrofit system to cathodically protect Marathon Oil UK LLC’s West Brae field manifold. The existing system was in need of repair, and the solution had to enable a full-integrity maintenance repair without major disruption to ongoing production.
