White paper: How induction heating saves time and money for the offshore industry
The application of heat is often the only way to repair, remove or install equipment essential to offshore operations. Unfortunately, traditional heating methods and offshore operations don’t mix well. Safety concerns make the application of heat problematic. The use of gas-fired open flames, for example, is prohibited in many environments. If alternative heating methods are not employed, equipment may have to be disassembled and shipped ashore, driving up costs and perhaps even threatening production.

Induction heating of live pipeline for hyberbaric diver welding
The Statoil Tampen Link project brought a 12” branch pipe into a 20” main line using a welded branch pipe and a hot-tap drill through. All conducted with diver operations on a high pressure gas pipeline at 145m (475’) water depth. The paper describes the first subsea operational use of the EFD induction heating system which was used to provide the welding pre-heat. This provided high heat input, to counteract the cooling gas flow, without discomfort or hazard to the welder divers. More about hyberbaric diver welding
