Project review
RetroLink system used to replace the cathodic protection system for loading dock in the Bahamas

Overview

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)

Installation

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.
