Norwegian engineering firm Aker Solutions said on Aug. 2 it has won a contract from Shell Plc to build an offshore platform for Britain’s Jackdaw gas field.

The offshore field about 250 km east of Aberdeen is expected to account for over 6% of British North Sea gas output at its peak production in by the middle of this decade, Shell has said.

To lower the costs, the field will be produced by using a wellhead platform that is not permanently manned, tied back to the nearby Shearwater platform.

Aker Solutions said it would book an order intake of between 2 billion and 3 billion Norwegian crowns (US$206 million-US$309 million) for the contract in the third quarter.

“We are pleased that Shell selects us to develop a cost-effective platform for this major North Sea gas field,” Aker Solutions said in a statement.
