Aker Solutions has secured two contracts worth at least US$112 million (NOK 900 million) from DEA Norge to deliver the subsea production system, maintenance and services at the Dvalin natural gas development offshore Norway.

The first order is for a production system encompassing a manifold, four subsea trees and a 15km-long umbilical that will connect to the adjacent Heidrun platform. It also covers wellheads, controls, tie-in and workover systems and options for further subsea production tie-back connections to Heidrun. Initial deliveries are slated for 1H 2018.
The companies also agreed on a five-year framework contract for maintenance and servicing of all subsea production systems ordered under the first agreement, including installation and commissioning services. The contract may be extended by three-year periods.
"Dvalin is DEA's first development as an operator in Norway and we look forward to working together to sustainably maximize the full potential of this field," said Luis Araujo, Aker Solutions CEO.
The value of the subsea production system as well as related installation and commissioning services is about NOK 900 million and will be booked in Q4 orders. The size of the framework agreement depends on the amount of work necessary and orders will be booked as they come in.
The work will primarily be carried out in Norway, with management, engineering and procurement for the subsea production system handled at Fornebu. Subsea trees will be delivered from the plant in Tranby, manifolds from the Egersund yard, the umbilical from the factory in Moss and controls systems from Aberdeen, in the UK. Maintenance and services will be provided by the company's service base in Ågotnes, Norway.
The Dvalin field, formerly named Zidane, will be developed as a subsea tieback to the adjacent Heidrun platform in the Norwegian Sea. Gas from the field will be transported via Heidrun through the Polarled pipeline to the Nyhavna processing plant before being sent to the European market.
The plan for development and operation is currently under review by the Ministry of Petroleum and Energy (MPE) and the Norwegian Petroleum Directorate (NPD).
Also today (4 October), Aibel announced its Dvalin win for modification work to ready the Heidrun platform to receive the production from the field.
