Two retrofits in two days

Deepwater retrofit two platforms in the Gulf of Mexico with RetroLink™ anode strings.

The first platform is a four-leg structure in 125 feet of water that required 16 RetroLinks™, fourteen of which were suspended from horizontal weld-on stand-offs and two more suspended from vertical weld-on stand-offs. Average maximum pre-installation potentials were -748 mV, and average post-installation potentials were -1012 mV.

The second platform is an eight-leg structure in 57’ of water that required 15 RetroLinks™, all of which were suspended from horizontal weld-on stand-offs.

Average maximum pre-installation potentials were -658 mV and average post-installation potentials were -855 mV. A VampClamp™ with a bonding cable attached to one of the legs was installed on a riser flange to provide electrical continuity with the pipeline and structure.

Most links required only about a half-hour each to install; installation took one day for each platform.
