Cathodic protection (CP) platform anode retrofit

Platform Anode Retrofit RetroPod Deployment from Deepwater

Acteon’s engineers have retrofit new anodes on more fixed platforms worldwide than anyone else.

When a platform’s original anodes are eventually depleted, installing replacements in the same manner – welding or bolting them all over the structure – is labor-intensive and expensive. Acteon offers much more cost-effective and extremely reliable retrofit systems utilizing remote seabed anodes placed around the platform that electrically connect to it via cables and clamps. Installation time and mobilization costs are greatly minimised.

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 experience. Our engineers have retrofit new anodes on more fixed platforms worldwide than anyone else.

  • Underwater welding – Early methods of replacing consumed anodes involved a one-for-one replacement with underwater welding. This method is extremely expensive, so it wasn’t long before operators sought newer methods.
  • Dual anode clamp-ons Rather than welding, divers can also bolt anodes to structural members and electrically connect the anode with through contact screw.
