Floating production specialist SBM Offshore has that the construction of the turret mooring system for Statoil’s Johan Castberg development in the Barents Sea is progressing well.

The Dutch company has been contracted by Statoil to to deliver a large-scale turret mooring system for Statoil’s Johan Castberg FPSO, to be moored 100 kilometers north of the Snøhvit-field.

Under the original contract awarded last year, the turret is planned to be delivered in modules in early 2020, will be moored in c. 370 meter water depth and will have a capacity to accommodate 21 risers.

After the award last year, SBM Offshore selected Dubai’s Drydocks World to construct parts of the turret mooring system.

In a statement on Thursday. SBM Offshore said the work on the Turret Mooring System for the project “is progressing well, in line with schedule.”

“The first steel cut in the Dubai Dry Docks World yard is targeted to be performed during May 2018,” SBM Offshore said.

The Johan Castberg FPSO will be permanently moored by the internal turret mooring system at the Johan Castberg field in offshore Norway. The system will allow the vessel to passively weathervane around the anchor legs while simultaneously transferring fluids, power, and communications signals between the vessel and subsea equipment.

Drydocks World is responsible for detail design of certain specified works, bulk procurement and construction including Super Duplex piping work and TLER / TLIR module.

Johan Castberg

Statoil in December 2017 submitted the plan for development and operation for the Johan Castberg project.

The field development concept includes an FPSO and a subsea development with a total of 30 wells, 10 subsea templates, and two satellite structures.

According to Statoil, this is the biggest subsea field under development in the world today.

The Johan Castberg development costs are estimated at around NOK 49 billion (approximately $5.9 billion).

Recoverable resources are estimated at 450 – 650 million barrels of oil equivalent. This makes the Johan Castberg project the biggest offshore oil and gas development to be given the go-ahead in 2017. First oil is scheduled for 2022.
