Aker Solutions has been awarded NOK4bn ($481.8m) contract by Statoil to support the development of the NOK49bn ($5.91bn) Johan Castberg field in the Norwegian Barents Sea.

Under the contract, Aker Solutions will be responsible for the supply of subsea production system as well as design the topside of the floating production, storage and offloading (FPSO) facility.

Located in PL 532, around 100km north of the Snøhvit-field, the Johan Castberg field is estimated to have 450–650 million barrels of oil equivalent. It is said to be the largest oil discovery in the Norwegian Barents Sea.

The subsea production system comprises 30 wells with vertical subsea trees, wellheads, control systems, 10 templates and manifolds, two satellite structures and tooling.

Aker, through its facilities in Norway, the UK, India, Malaysia and Brazil, plans to commence work on the system this month, with initial deliveries planned to begin in the second quarter of 2019 and complete in the first half of 2023.

Aker Solutions CEO Luis Araujo said: "Our early involvement and strong collaboration with Statoil have helped halve the development costs, enabling this strategically important project to move forward.

"The field is critical in further developing northern Norway as an oil and gas region."

Under the FPSO agreement, Aker will provide engineering, procurement and management assistance for the detailed design of the Johan Castberg topside. Work is planned to be completed in 2019.

Statoil is the operator of the Johan Castberg field with a 50% stake, while other partners include Eni with a stake of 30% and Petoro holding 20% stake.
