Subsea 7 has laid the first cables in the water for the
Hywind Tampen floating wind farm project for Equinor. Under its contract, Subsea 7 responsible for installation of electrical cables and connection to the Snorre and Gullfaks platforms.
Hywind Tampen is an 88 MW floating wind power project intended to be the world’s first floating wind farm to power offshore oil and gas platforms. It will connect to the five Snorre A and B, and Gullfaks A, B and C platforms, located approximately 140 km off the Norwegian coast.

The floating wind farm will consist of 11
SG 8.0-167 DD wind turbines based on one of Equinor’s floating offshore wind technologies, Hywind. With a 167 m-diameter rotor and 81.5 m-long blades, each turbine of the wind farm will have a swept area of 21,900 m².

The project is estimated to meet about 35% of the annual electricity power demand of the five Snorre A and B, and Gullfaks A, B and C platforms. The wind power solution will help reduce the use of gas turbine power for the Snorre and Gullfaks offshore fields, while also offsetting 200,000 tonnes of CO2 emissions and 1,000 tonnes of NOx emissions per year.
It will be operated from Equinor’s offices in Bergen.
Earlier this week Equinor revealed that it has pushed back the planned installation of four turbines at its Hywind Tampen floating wind project. The first seven turbines will come on stream this year as planned with the final four will be installed next spring.

Equinor stated that supply chain bottlenecks, most notably related to the global market for steel, preclude delivery of the final four tower sections for the wind turbines until September 2022. This will be too late in relation to the installation weather window for the year, postponing installation of the remaining four turbines until next year.
