Cathodic protection on the Dampier to Perth pipeline - Australia

OSTI ID:6159459
The Dampier-Perth Pipeline in Australia transports natural gas from the north to the south over a distance of 1540 km. The ground along the route is high in electrical resistivity. Coupled with the fluid bed epoxy (FBE) coating, this high electrical resistivity posed some special design problems for cathodic protection indirectly influencing spacing of cathodic protection stations, provision of groundbeds, compatibility of earthing, and groundbed interference. A major consideration at the design stage was IR voltage drop in the soil, which necessitated extensive manipulation of earthing placement and materials. Telluric currents were also of concern. This article provides insight into design considerations and also reviews the performance of the permanent cathodic protection system.
