Protection of Seawater Liftpump Caissons
Severe galvanic corrosion of seawater liftpumps is a problem for many years, corrosion rates higher than 10 mm/year have been recorded.
Ironhaven developed an easy but very effective way to protect the caisson over the full length. Sacrificial anodes are used and they control themselves on the ideal protection potential. Excellent corrosion protection and no over protection causing hydrogen embrittlement.
