Cathodic Protection
For Offshore Platforms

In 2009, Deepwater conducted cathodic protection retrofits for 124 structures in the Gulf of Mexico alone.

Deepwater provides cathodic protection for new structures and anode replacement or supplementation for aging offshore assets. Having rewritten the "CP retrofit textbook" with our ground-breaking anode replacement systems, Deepwater can retrofit a structure's cathodic protection system more quickly and more efficiently, reducing the cost to the operator by up to 40% over traditional methods. While the majority of the world's offshore infrastructure is beginning to reach the end of its original design life, it is more important than ever to address corrosion control and cathodic protection for valuable offshore assets. Our N.A.C.E. certified team of engineers and CP designers have provided, supplemented, or replaced the cathodic protection on every type of brown or green-field asset currently in operation.

For new platforms - For new build projects, we provide stock aluminum platform anodes , made at one our certified ISO 9000 anode foundries. All foundry facilities are located only a few miles from where the design team and engineers manage each project, ensuring that strict QA/QC oversight is observed for all anode materials used in our systems.

Sacrificial Anode Retrofits - For sacrificial retrofit situations, where impressed current cathodic protection (ICCP) is not an option, we usually recommend the RetroPod (including the RetroClamp) system, due to its continued track record of success. For shallow water platforms, the RetroLink system is also a popular solution among operators

Impressed Current Retrofits - For anode retrofit projects on larger structures, or structures in deeper waters, where the designer is required to provide a lot of cathodic protection current, we employ the RetroBuoy ICCP retrofit system. Providing up to 400 Amps of CP for up to 25 years, it is the most effective and efficient cathodic protection anode sled on the market, ideal for any large structure, complex, or FPSO with an available power source.
