ABB won a contract worth $170 million from Subsea 7, to build an undersea power transmission link between a new oil and gas field being developed by Total E&P Norge AS in the North Sea and the Norwegian power grid.
The Martin Linge (formerly known as Hild) field lies at a depth of 115 meters and has been identified among the oil and gas fields with highest potential reserves in the North Sea. The field will receive its electricity feed through a 162-kilometer high-voltage submarine power transmission cable that will lie 370 meters below sea level, at its deepest point.
The 145-kV high-voltage three-core polymeric insulated (XLPE) submarine cable will be capable of supplying up to 55 MW of AC (alternating current) power from the mainland grid to the new Martin Linge field. The cable will include fiber optic links to allow the facilities to be controlled from shore.
ABB’s high-voltage XLPE submarine cables have low electrical losses, tensile strength and are resistant to solvents, oil and abrasives.
ABB’s project scope includes the technical pre-studies, design, engineering, production and installation of the high-voltage cable system. The cable link will power a wellhead and production platform, a floating storage and offloading vessel. Production from the field is expected from 2016.
