Deepwater installs ICCP anode system to protect wind farms in the Irish Sea

Seven offshore wind turbines had prematurely failing cathodic protection anodes.

Deepwater developed a completely new type of impressed current anode system.



The VSE assemblies were installed 10 m to 15 m from the base of the monopiles. Dual-armored single-conductor cable was routed from the VSEs, across the bottom to the base of the monopiles and then up through specially-installed I-tubes to the rectifiers located at the (+) 13 m elevation. The systems, including I-Tubes, were installed on all seven monopiles in a total of eleven work days utilizing a dive support boat with lifting “A” frame. In addition, DR-2 CD polarization monitors were installed to monitor the performance of the new CP system.
