Cathodic Protection for Deep Water Assets

Deep water cathodic protection using a modular anode structure
with on-board status monitoring.
A SmartPod protecting and monitoring two sub-sea trees.
The SmartPod system is an intelligent version of the well-proven RetroPod™ cathodic protection system for offshore platforms. The system greatly simplifies deep water cathodic protection by providing a modular anode structure with on- board status-monitoring, using the patented SunStation™ cathodic protection monitor technology (each unit contains 3 SunStation monitors).
Each SmartPod can protect a number of discrete subsea structures and can be configured to provide 20 years of cathodic protection to over 25,000 square feet of coated steel.
RetroClamps allow an ROV to connect to the subsea structures, and Polatrak® V-String™ reference electrodes provide the CP monitoring.
SmartPods can be quickly installed with any Work Class ROV system, and instant feedback on current output and potential of protected structures is displayed on the SunStation™ readout.
Like all of Deepwater’s innovative CP solutions, the SmartPod is guaranteed to perform.
SmartPod uses the highest available quality of sacrificial anode alloys. All steel fabrication uses ASTM A 36 material and is performed in Deepwater's own manufacturing facilities.
The Sunstation monitor is a self-contained CP monitoring terminal powered strictly by the light from an ROV. This eliminates the use of batteries, making SunStation ideal for deepwater applications. Solar panels and LED’s are housed separately in either Delrin for use in < 300 m or Stainless Steel for use in < 3000 m.
RetroClamp™ Tie Back
Each SmartPod is shipped with one or more RetroClamps. Typical cables are 2 x 25 feet #4/0 AWG heavy-duty flex cables. Thousands of these clamps are now in service around the world, and many have been installed by ROV. The installation efficiency of the RetroClamp has cut installation costs and allowed for tie-back to any pipe or tubular.
A concrete mattress at the base provides ballast for stability. CP monitoring is provided by a SunStation monitor with 3 readouts.
