Deepwater CP Retrofit Systems RetroPod™ RetroClamp™
RetroPod systems have saved many operators hundreds of thousands of dollars in offshore CP retrofit costs. This is achieved by installing an optimized array of sacrificial anode material on bottom, just inside or outside the base of the jacket. This semi-remote location greatly improves current distribution, can be installed by divers or ROVs, and can be installed in less than a quarter of the time it would take to install a single, conventional clamp-on array. Deepwater Corrosion Services, Inc. is a globally recognized leader in offshore and marine cathodic protection innovation. Our depth of experience is unparalleled in the industry.

RetroClamp provides a method for quickly making an electromechanical tie-back connection to a subsea cathodic protection system. Originally designed for pipeline CP retrofit applications, the RetroClamp is now routinely used in a variety of subsea CP retrofit applications.
For pipeline applications, clamp is installed over all coatings. Indicate thickness of corrosion coating and weight of coating, if applied.

Deepwater CP Retrofit Systems VSA™
The VSA (Vertically-Suspended Anode Array) is an improved method for direct mounting of anodes to offshore jacket str uctures. The anodes are suspended vertically, rather than horizontally from susbsea members. VSA anode arrays are typically used to supplement RetroPodbased CP retrofits; they are not recommended as stand-alone systems. Advantages of the VSA versus conventional clamp-on arrays • The VSA reduces mutual interference, providing around
10% more current output • Safety – the VSA arrays require minimal diver inter vention • Economics – the VSA installation saves about 30%
in installation costs due to reduced cleaning and simplified rigging Deepwater Cor rosion Services, Inc. is a globally recognized leader in offshore and marine cathodic protection innovation. Our depth of experience is unparalleled in the industr y. Part Number Current (A) * VSA-10 VSA-20

Deepwater CP Retrofit Systems Dual Clamp-On
The Dual Clamp-On anode system is a tried and tested, albeit inefficient method of deploying retrofitted sacrificial anodes to offshore platforms. This is not a system widely recommended by Deepwater Corrosion, but it does have some limited applications, such as high current flow areas, where these anodes would be used in place of our Ver tical Suspended Anodes (VSA) to supplement RetroPod systems on large structures. Given that a demand remains for these systems, Deepwater has optimized the design so as to minimize mutual interference between anodes, and to provide a reliable, long-term mounting system. Deepwater Corrosion Services, Inc. is a globally recognized leader in offshore and marine cathodic protection innovation. Our depth of experience is unparalleled in the industry.
