In 2008, Deepwater Corrosion Services, Inc. was commissioned by the Bahamas Oil Refining Company to replace an impressed current cathodic protection system which had been totally destroyed by a hurricane. The system had been protecting a loading dock. The designers decided not to use another impressed current system, but use sacrificial anode strings instead. The assets to be protected included:
• Loading dock (replace all topside systems)
The retrofit cathodic protection (CP) system consisted of:
• 154 x RetroLink Anode Strings (each 90 ft long)
The loading dock in question was actually a crude-oil loading terminal, comprising multiple isolated jacket and dolphin structures. 154 RetroLink (Deep) sacrificial anode systems – each string rated 17 amperes – were used. Customer was able to effect installation at his own pace using existing boats with no divers.
