The 88 MW Hywind Tampen offshore wind farm is the world’s largest. It is also the first to power offshore oil and gas platforms. It produced power for the first time on Sunday, 13 November 2022.

Seven of the wind farm’s turbines have now come on stream, with the installation of the remaining four Siemens Gamesa SG 8.0-167 DD turbines taking place in 2023. Located approximately 140 kilometres off the coast of Norway, in depths ranging from 260 to 300 metres, it will now supply 35% of needed power to the Snorre and Gullfaks oil and gas fields in the Norwegian North Sea. The project will reduce Norwegian CO2 emissions by over 200,000 tonnes a year, according to the Norwegian operator, Equinor.

The 277.89 million pound contract for the key components of the Hywind Tampen project was finalised by Equinor in October 2019. DEME Offshore was engaged for a front-end engineering and design (FEED) study of the potential floating concrete substructures for the project, while Aker Solutions was contracted for the engineering, construction, and installation of the 11 concrete spar-buoy floating substructures.

Siemens Gamesa Renewable Energy (SGRE) provided the SG 8.0-167 DD wind turbines and was awarded a five-year maintenance contract for them. Mammoet then completed its load-in, marshalling and turbine assembly scopes for the OWF. Then, Subsea 7 installed cables provided by JDR Cable System. The Copenhagen-based software company, ConWX, designed a power forecasting algorithm to better inform OFW operations.
