Siemens to deliver compression train for Statoil’s Johan Castberg FPSO

SGT-750 gas turbine

Germany’s Siemens has been awarded a deal to supply a gas turbine compression train for the Johan Castberg FPSO.

Siemens said on Tuesday that it was selected to engineer, manufacture and commission a gas turbine-driven compression train for Statoil’s Johan Castberg floating production, storage, and offloading (FPSO) vessel.

According to the company, the project represents the first offshore application of the SGT-750 gas turbine with delivery scheduled for mid-2019.

The equipment includes a 41-MW SGT-750 gas turbine that will drive two DATUM compressors operating in a tandem arrangement. The compressors will reinject gas to pressurize the oil reservoir.

Siemens will also supply a waste heat recovery unit to recover gas turbine exhaust heat that will be distributed as heated liquid to prevent ice build-up on key surfaces of the superstructure.

Siemens added that the SGT-750 gas turbine enabled long maintenance intervals and was capable of driving the compressors without a speed increasing gearbox.

Matthew Chinn, executive vice president of the Dresser-Rand business New Equipment Solutions, said: “This contract, placed as part of our frame agreement, exemplifies the confidence Statoil continues to place in us because of our proven track record of highly efficient, low-emission equipment for offshore production facilities.

“The performance of the mission-critical equipment for this project not only lowers the total cost of ownership but offers long maintenance intervals, which in turn reduces maintenance costs and increases production uptime.”

Earlier this month, several companies won deals for work on the Johan Castberg project. Namely, Kvaerner signed a contract with Statoil for delivery of the topside modules for the Johan Castberg FPSO as well as for hook-up and integration of the topside modules with the hull.

As subcontracts to Kvaerner, Aker Solutions’ yard in Egersund will deliver the modules for water and chemical injection, while the company’s facility in Sandnessjøen will deliver smaller modules and the flare boom.

Palfinger Marine won a deal to supply four FF1200 freefall lifeboat systems to for the FPSO while Ocean Installer won a contract for marine operations on the Johan Castberg project.

The Johan Castberg field is situated approximately 100 kilometers north of the Snøhvit field in the Barents Sea. The field is operated by Statoil, with Eni and Petoro as partners.

The field development concept includes an FPSO and a subsea development with a total of 30 wells, ten subsea templates, and two satellite structures. First oil is scheduled for 2022.
