Equinor has awarded a contract to an offshore base at a harbour on the west coast of Norway to assemble the turbines for the Hywind Tampen offshore windfarm.
The company has selected Wergeland Base at Gulen Industrial Harbour in Sogn og Fjordane county to assemble the floating wind turbines before they are transported to the offshore oil and gas field in the North Sea, although no work will commence prior to an investment decision on Hywind Tampen.
As previously highlighted by OWJ, Hywind Tampen could become the world’s first project to use offshore wind turbines to provide electric power to oil and gas installations.
The company stated that a floating offshore windfarm providing power to its Snorre and Gullfaks fields would reduce CO2 emissions by more than 200,000 tonnes per year compared with generating electricity on the platforms using gas turbines.
Equinor has completed a study evaluating which oil and gas installations on the Norwegian Continental Shelf are best-suited for power from a floating offshore windfarm. The Snorre and Gullfaks fields in the Tampen area in the northern North Sea were found to be the best match.
The company is exploring using a floating offshore windfarm consisting of 11 wind turbines based on Equinor’s Hywind concept. The 8-MW turbines will have a combined capacity of 88 MW and would meet about 35% of the annual power demand of the five Snorre A and B, and Gullfaks A, B and C platforms. In periods of higher wind speed this percentage will be significantly higher.
Equinor project director Olav-Bernt Haga said the contract was awarded a contract to Wergeland Base based on a number of operational commercial factors.
The contractor will provide onshore and inshore areas for storage, assembly and commissioning of all the components for the floating wind turbines, along with the necessary infrastructure and facilities. The floating wind turbines will be towed to the field where they will be anchored, connected and put into operation.
