SGRE will deliver 11 8MW turbines with 167-metre rotors to the 88MW floating wind project, which will be used to power the Snorre and Gullfaks oil and gas fields in the North Sea.
It will be the third time SGRE has supplied Equinor for its floating projects, having previously provided a 2.3MW machine for the Hywind Demo project in 2009 and the five 6MW turbines operating at the 30MW Hywind Scotland site off the UK since 2017.
SGRE will service the turbines for five years.
Equinor’s Hywind Tampen be installed 140km from shore in water depths of 260-300m between the Snorre and Gullfaks oil and gas platforms.
The developer predicts the project meeting about 35% of the annual power demand of the Snorre and Gullfaks platforms, reducing emissions from the project by around 200,000 tons a year.
Electrical cables for the project will be provided by UK-based JDR Cables, while Subsea 7 will be responsible for their installation.
In a change from the previous Hywind projects, the floating foundation hulls will be produced in concrete by Norwegian engineering firm Kvaerner — a subsidiary of Aker Solutions.
Kvaerner said concrete fabrication has a lower CO2 footprint than other methods.
As EPC contractor, Kvaerner will be responsible for producing and installing the foundations at the project site. The early construction phase will begin at the Stord dry dock in Norway — where assembly of the Hywind Scotland turbines also took place.
