Nandlal, S; McGuire, D P

A method and apparatus for supplementing the substructure of an offshore platform within, or in the vicinity of, the well conductors of the platform so as to add large numbers of anodes distributed vertically within the platform adjacent the well conductors. A number of anodes are attached to the outer surface of a number of short sections of pipe. The pipe sections are lowered down through the platform where each section is anchored to a preselected cross-bracing platform member. These anode carrier sections are connected together under water to form an elongated tubular support for the anodes.
