Anodes for Marine Cathodic Protection

Subsea equipment typically utilises protective coatings as the primary measure for protection against external corrosion. Due to a variety of reasons, which could include inadequate surface preparation or application, damage and coating degradation over the service life, anodes must be applied as a backup system to prevent corrosion on surfaces not protected by coatings. The protective current necessary may be provided by the use of electronegative materials such as aluminium or zinc (sacrificial-anode cathodic protection), or alternatively by the use of relatively inert anodes with an external direct-current power source (impressed-current cathodic protection).

Jennings Anodes can provide cathodic protection solutions to many types of offshore structures and subsea equipment such as wind turbine foundations, platform jackets, mobile rigs, mooring buoys, harbours, jetties, piers, wharfs, pilings or submarine pipelines.
