In 2004, Deepwater Corrosion Services, Inc. was commissioned to develop a pile anode for a pier in the Cook Inlet, Alaska. The Raparound pile anode was developed and commissioned to address the uniquely harsh environment. The wharf itself freezes and thaws each winter, completely encasing the piles in ice.
The retrofit cathodic protection (CP) system consisted of:
• 36 x Raparound Pile Anodes (rated 50 Amperes each)
Deepwater Corrosion Services, Inc. was commissioned in 2004 to develop a pile anode strong and reliable enough to survive the deep freezes of the Cook Inlet in Alaska. The result was the Raparound pile anode. The Raparound is the only cathodic protection system on the market for such harsh conditions. The photos below were taken after the second winter in service (Feb 2006); not a single failure or low cathodic protection potential reading was found.
