  • Retrofit cathodic protection maintains subsea asset integrity


    Gordon McKinnell

    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.
