Composite materials, primarily carbon fiber and epoxy resin, that are lightweight, yet offer a high-degree of strength and durability provided a way to repair corroded piping on two North Sea platforms without having to shut in production. BP PLC during routine nondestructive testing on its Lomond and North Everest platforms found the closed-drain systems to have internal corrosion along 2-inch carbon steel pipes. Girth weld locations were the most affected areas, 15 sites in total, although two flange connectors and an isolation valve also displayed signs of corrosion. The repair of this corroded piping was made by a method used by FDA (FD Alliance), a co-operative venture between the engineering group DML (Devonport Management Ltd), owner and operator of Devonport Royal Dockyard Ltd, Plymouth, UK and the engineering company Furmanite International Ltd, Kendal, UK. The closed-drain system runs at a design temperature of between -6 and 20 deg C, and therefore is well within the 100 deg C recommended design maximum for standard composite repairs, according to FDA.
