Nexans has won a Eur 15 million contract from Statoil to supply electrical heating cables, heating cable risers and protective equipment for the subsea flowlines on the Kristin field in the Norwegian Sea.

The contract has been placed by the operator, Statoil, on behalf of the licensees for this Norwegian Sea field.

It covers heating cables, electrical risers and a mechanical-protection solution for installation piggyback on the flowlines which connect the subsea installations with the floating production platform on the Kristin field.

The heating system will prevent hydrate (hydrocarbon ice) from forming in the pipelines during unplanned production shutdowns.

"This is the third direct electrical heating system Statoil has ordered, indicating that the system is successful and something that the company wants to focus on in future", said Yvon Raak, Nexans' Executive Vice President, Europe Area.

The electrical heating system, which is installed on the Asgard field in the Norwegian Sea and the Huldra field in the North Sea, has been developed by Statoil in collaboration with Nexans and other Norwegian suppliers.

The wellstream of the Kristin Field has a particularly high temperature which has required further development of the piggyback system.

The equipment will be manufactured at Nexans' Halden factory, south of Oslo, with installation work being carried out under an existing contract awarded to Technip Offshore Norge.

The Kristin field is due to produce from 12 subsea wells tied back to a floating platform.

Its production capacity will be an estimated 126,000 barrels of condensate and 18 million cubic metres of gas per day.

Production is planned to start in the summer of 2005.
