OSLO, Norway -- Aker Subsea has won a NOK 80-million ($13-million) contract to supply direct electrical heating systems (DEH) for subsea pipelines for ENI’s Goliat field development in the Barents Sea.

DEH is a designed to avoid hydrate and wax formation in pipelines transporting oil from seabed manifolds to the offshore production facility. Use of DEH cables prevents hydrate-induced blockages during shut-down periods, minimizing the need for chemicals and optimizing shut-downs.

"The oil from the wells may freeze and create a plug in the pipeline if the production stops. The current from the cables heats the pipelines and the oil content so that it remains viscous until production can start again," says Tove Røskaft, senior VP for Umbilical Technology, Aker Solutions.

Technip is the pipeline installation contractor for Goliat. The DEH cables will be assembled at Aker Solutions’ cable and umbilical plant in Moss, Norway, with final deliveries scheduled for spring 2013.
