Cook Inlet Pier
Deepwater develops the Raparound™ impressed current pile anode for harsh conditions in Alaska
Deepwater develops and commissions the first Raparound™ Pile anodes for the harsh conditions of the Cook Inlet in Alaska
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 Raparound™ Pile Anodes (rated 50 Amperes each).
Protection even in brutal cold
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 only cathodic protection system on the market for such harsh conditions. The photos shown were taken after the second winter in service (Feb 2006); not a single failure or low cathodic protection potential reading was found.
After the thaw
Raparound anodes perform through freeze and thaw cycles
Frozen
Anodes become completely encased in ice during the freeze.
Protection when needed
Once the piles become submerged, the Raparound delivers 50 amps of CP current.
Rapid installation
Each Pod / Clamp was installed in an average of 1.5 hours.
