Nexans awarded contract to supply power cables, umbilicals and accessories for Statoil's Åsgard oil and gas field in Norwegian SeaNexans awarded contract to supply power cables, umbilicals and accessories for Statoil's Åsgard oil and gas field in Norwegian Sea

Nexans, a worldwide leading expert in the cable industry, has been awarded a 75 million euro contract by Statoil to design, manufacture and supply a total of 165 km of static and dynamic power umbilical and power cables, as well as necessary accessories, for the Åsgard oil and gas field in the Norwegian Sea.



Nexans's specialized manufacturing facilities in Norway, Halden, Rognan and Namsos as well as Charleroi in Belgium, will be involved in the completion of this complex subsea project. Nexans will supply four lengths of power cable and power umbilical, each 40km long, two lengths of dynamic power umbilical, and 2.3 km of standard service umbilical cable.

Ragnvald Graff, Sales and Marketing Director of the Energy Division in Nexans Norway says: "Winning this power umbilical project as part of a broader Statoil project is a real testament to our technology and products. In this project Nexans will in close cooperation with Statoil push innovation and technology to fulfill the projects very demanding needs."

Åsgard oil and gas field

The Åsgard oil and gas field is located in the Norwegian Sea approximately 200km off the coast of mid Norway, and delivers around 28 billion cubic metres of gas and 14 million barrels of condensate, which is equal to 220 million barrels of oil equivalents.

The Åsgard oil and gas field comprises: Åsgard A, a Floating Production Storage and Offloading vessel; Åsgard B, a floating semi-submersible gas production platform; and the Åsgard C Vessel, which is used to store gas condensate (light oil).

The Midgard and Mikkel subsea fields are tied back to Åsgard B. They are losing the pressure required to pipe their well streams back to the floating semi-submersible gas production platform, Åsgard B. Statoil plans to use a subsea gas compression system to help recover the remaining reserves from these fields.

The power umbilical

The power umbilicals, pioneered by Nexans, integrate the functions of power cables and umbilicals in a single cable, enabling a high-voltage (HV) supply to be provided for deepwater projects. The power umbilical includes a number of steel tubes as well as fiber-optic elements, signal cables for control and monitoring as well as insulated power cores, all being supplied from Nexans' own factories. By eliminating the need to transport and install separate power and control umbilicals, the power umbilical significantly reduces transportation and installation costs.
