RetroPod™
Cathodic protection anode replacement for platforms
Materials
RetroPod uses the highest-available quality of sacrificial anode alloys. Typical ambient and cold water Al-In-Zn compositions are used. All steel fabrication uses ASTM A 36 material and is performed in our own manufacturing facility as well as at sub-licensed facilities in various regions. Sub-licensee list available upon request.
Design life
RetroPod system design life is 10 – 30 years (depending on customer requirements).
RetroClamp tie-back
Each RetroPod is shipped with one RetroClamp; typical cables are 2 x 25 feet #4/0 AWG heavy duty flex cables. The clamp can be installed by diver or ROV on any tubular member.
Aluminum anode material
Offshore cathodic-protection with sacrificial anodes requires the highest-quality aluminum. Deepwater Gaus-brand-anodes are available in one of two aluminum alloys (Deep7 and Deep10), each utilizing a chemical composition unique for performance in either tropical or cold, deep water (respectively). For full aluminum anode specs, visit the anodes section.
