Aker Solutions has been awarded the contract for the subsea production system for Dvalin and Aibel has been awarded the contract for modules and offshore integration at the Heidrun platform. In total the Dvalin licence will award contracts worth EUR 530 million (NOK 4.5 billion).

“These contracts are a major step in our effort on getting the Dvalin field developed, and we are very satisfied with having Aker Solutions and Aibel on board,” says Hans-Hermann Andreae, Managing Director of DEA Norge.

The 300-tonne subsea template for Dvalin and the umbilical connected to Heidrun will be built by Aker Solutions.

The two new modules at the Heidrun platform, one 4,000-tonne module for gas treatment and one 400 tons injection system, will be built by Aibel. These topside modifications for tie-in of Dvalin to Heidrun will be planned, executed and operated by Statoil.

“The Dvalin licence will award contracts with a value of EUR 530 million (NOK 4.5 billion) over the next couple of weeks. These contracts will create hundreds of jobs in a demanding time for the supplier industry”, says Andreae.

In total 68% of the value creation at Dvalin will come from Norwegian suppliers, and it is estimated that the work will create over 6,000 man-years for the supplier industry.

Dvalin will be developed with a four wells subsea template, which is connected to the Heidrun platform. At Heidrun, the gas will be partly processed in a new module, before the gas is transported in a new export pipeline to Polarled, going to the Nyhamna onshore gas terminal. At Nyhamna, the processing of the gas will be finalised, and the gas transported to the European market.

Recoverable reserves of the Dvalin field are estimated to around 18.2 billion cubic metres gas and 0.4 million cubic metres of condensate. The field is located in PL435, blocks 6507/7/9 and 6507/8 in the Norwegian Sea, approximately 15 km north west of Heidrun and 290 km from Nyhamna in Mid-Norway.
