Impressed current cathodic protection of off-shore platforms utilizing the tensioned anode ropes system

摘要

The present invention concerns a system for cathodic protection of off-shore structures, by the impressed current method, which system comprises tubular anode assemblies (1, 1ʹ), coaxially applied onto power supply cables (4), supported by ropes (5) tensioned between anchoring bodies (15) and the structure to be protected (17) or directly supported by the structure to be protect­ed. The tubular anodes, the relevant hydraulic sealings and electrical connections and the power supply cables (4) are not subjected to the mechanical stresses affecting the support.
