Protecting Submerged Steel From Corrosion
Vessel hulls and marine structures are continuously exposed to seawater, creating conditions where corrosion can develop over time. Sacrificial anodes are installed to help protect submerged steel by becoming the preferred point of electrochemical corrosion.
During underwater inspections, divers can assess the visible condition of installed anodes and identify areas where anodes are missing, damaged or significantly consumed. This information helps vessel operators and technical teams determine whether replacement or further maintenance is required.
Controlled Anode Installation and Replacement
Underwater anode replacement requires careful preparation and correct positioning. The working area should be inspected and cleaned where necessary so the replacement anode can be installed securely on the intended steel surface.
Depending on the structure and technical requirements, replacement anodes can be installed using suitable underwater welding and attachment methods. The completed work can also be visually inspected and documented to confirm positioning and general condition.

Supporting Long-Term Corrosion Protection
Maintaining an effective cathodic protection system is an important part of protecting submerged steel surfaces throughout the operational life of a vessel or marine structure. Regular inspection allows heavily consumed anodes to be identified before protection is significantly reduced.
Underwater replacement provides operators with a practical maintenance option while the vessel or structure remains in the water. This helps maintain corrosion protection between scheduled dry dock or major maintenance periods.
