Abstract:

A clamp apparatus is provided for use in securing cathodic protection, single anodes, double anodes, riser clamps and the like to the offshore drilling platforms and the like in a marine environment. The apparatus provides a U-shaped channel for fitting against the surface of, for example, the platform leg with a first section extending angularly out from the wall portion of the channel, and a second section extending out from the second wall of the channel. A chain bolt connector is inserted into a provided hole in the first plate section with the chain wrapped around the leg of the drilling platform and end chain links then inserted into a keyhole in the second plate extension and locked in by a movable plate. The nut bolt is then tightened to secure the apparatus against the leg of a platform. A set screw makes contact with the platform leg to complete the cathodic protection circuit.
