Dock and jetty cathodic protection
A number of options for docks and jetties
Depending upon the variables involved, including the length of life extension desired, water depth, harshness of the environment and the potential for damage from typical dock activities, Deepwater has several retrofit designs to match virtually any scenario. The optimal design is sometimes a combination of anode types.

THERE IS NO DESIGN CODE FOR ANODE RETROFIT
Unlike designing anode systems for new platforms, a retrofit designer must consider the state of the remaining cathodic protection. Often this data is not available, and the designer must make certain assumptions based on past experience. Deepwater's engineers have retrofit new anodes on more fixed platforms worldwide than anyone else.

RETROFITTING NEW ANODES
Early methods of replacing consumed anodes involved a one-for-one replacement, either by welding above the water line or underwater. This method is extremely expensive to install.
DUAL ANODE CLAMP-ONS
If welding is not an option, divers can also bolt anodes to tubular structural members and electrically connect the anode with through a contact screw.
