Gjøa power cable letter of intent

Statoil has sent a letter of intent to Swedish company ABB Power Technologies for the manufacture and installation of a power cable from the North Sea’s Gjøa field.

Power cable laying will begin in 2009 with final tie-in to the field in 2010.

The contract is worth some NOK 500 million and covers engineering, procurements, manufacture and installation.

The roughly 100-kilometre-long cable will run from Mongstad, north of Bergen, to the Gjøa platform.

“A solution with power supply from land via cable will have less of an environmental impact compared to a traditional solution with electricity produced at sea,” says Bjørn Midttun, who heads subsea and pipelines technology on the Gjøa project.

The reduction in carbon emissions from Gjøa at full production will equate to the emissions from 100,000 cars, providing the field is supplied with power from the Mongstad energy project’s (EVM) combined heat and power station (CHP).

The cable will be the world’s longest for transfer of high-voltage alternating current to floating installations,” explains Mr Midttun.

“The concept is based on a dynamic high-voltage cable and can be used on other floating installations.”

Plans call for the Gjøa field to come on stream in 2010.
