Deepwater Aloline process vessel anodes are cast in low-iron, high efficiency aluminum alloys, and can be manufac-tured in a wide variety of configurations to suit your specificvessel application.

If you are experiencing premature consumption of sacrificialanode alloys in process vessel applications, please consultDeepwater Corrosion Services for advice on anode selection.

Process Vessel AnodesAluminum



RetroPod systems have saved many operators hundreds ofthousands of dollars in offshore CP retrofit costs. This isachieved by installing an optimized array of sacrificial anodematerial on bottom, just inside or outside the base of the jacket.This semi-remote location greatly improves current distribu-tion, can be installed by divers or ROVs, and can be installed inless than a quarter of the time it would take to install a single,conventional clamp-on array.


RetroClamp provides a method for quickly making an electro-mechanical tie-back connection to a subsea cathodicprotection system. Originally designed for pipeline CPretrofit applications, the RetroClamp is now routinely usedin a variety of subsea CP retrofit applications.

The VSA (Vertically-Suspended Anode Array) is an im-proved method for direct mounting of anodes to offshorejacket structures. The anodes are suspended vertically,rather than horizontally from susbsea members.

VSA anode arrays are typically used to supplement RetroPod-based CP retrofits; they are not recommended as stand-alonesystems.

Advantages of the VSA versus conventional clamp-on arrays

• The VSA reduces mutual interference, providing around10% more current output

• Safety – the VSA arrays require minimal diver intervention

• Economics – the VSA installation saves about 30%in installation costs due to reduced cleaning andsimplified rigging

The Dual Clamp-On anode system is a tried and tested,albeit inefficient method of deploying retrofitted sacrificialanodes to offshore platforms. This is not a system widelyrecommended by Deepwater Corrosion, but it does havesome limited applications, such as high current flow areas,where these anodes would be used in place of our Ver ticalSuspended Anodes (VSA) to supplement RetroPod systemson large structures.

Given that a demand remains for these systems, Deepwaterhas optimized the design so as to minimize mutual interfer-ence between anodes, and to provide a reliable, long-termmounting system.
