This Standard specifies requirements for the cathodic protection of external surfaces of fixed immersed structures, including offshore platforms, wharves, jetties, pontoons, sewage treatment plants, water treatment plants, lock gates, dam gates, pump station piles in rivers,weirs, mooring buoys, piling, foundations and water inlet/outlet structures.
Whilst fixed immersed structures are rarely affected by stray direct traction currents, there are some significant examples where this does occur and where mitigation is required.Examples of affected fixed immersed structures are underwater tunnels and electrically continuous sheet piling along water-ways and harbours.
