STAVANGER, Norway – On behalf of the Gullfaks and Snorre partners, Equinor has signed contracts totaling about NOK3.3 billion ($359 million) for the Hywind Tampen offshore wind farm development.
The contracts have been awarded to Kværner AS, Siemens Gamesa Renewable Energy AS, JDR Cable Systems Ltd., and Subsea 7.
Kvaerner’s scope comprises engineering, procurement, and construction of 11 floating concrete hulls for the wind turbines.
The initial phase of construction will start in the drydock at the company’s facility at Stord in Norway. The bottom sections will then be floated to the site at Dommersnes in the Vindafjord where the construction will be completed. Finally, the wind turbines will be installed on top of the concrete hulls in Gulen.
The project will start immediately and is expected to be completed during autumn 2022.
In addition, Kvaerner’s contract includes delivery of the marine operations phase. This includes the full project management, engineering, assembly site management, mooring system installation, units tow-to-field and installation of the floating wind turbine units at the Tampen area. Marine operations will be performed as an integrated subcontract to the main contract, executed in a 50/50 joint venture between Kvaerner and DOF Subsea.
Siemens Gamesa’s scope comprises design, procurement, and fabrication of 11 SG 8.0-167 DD turbines, assembly and completion inshore and offshore.
JDR Cable Systems’ scope comprises design, procurement, and fabrication of two export and 11 inter-array cables.
Seaway 7, Subsea 7’s Renewables and Heavy Lifting business unit, will install the cables.
Hywind Tampen will be located around 140 km (87 mi) offshore in 260-300 m (853-984 ft) of water between the Snorre and Gullfaks platforms.
The oil and gas platforms will be the first ever powered by a floating offshore wind farm, according to Equinor. Emissions from the Gullfaks and Snorre fields are expected to be reduced by more than 200,000 metric tons (220,462 tons) per year.
The 88-MW offshore wind farm is expected to meet around 35% of the annual power demand of Snorre A and B and Gullfaks A, B and C platforms.
The Hywind Tampen investment will be about NOK5 billion ($544 million). All contracts are subject to final approval of the plan for development and operation by the Norwegian authorities. The wind farm is scheduled to start production at the end of 2022.
