DOF Subsea Installs Suction Anchors on World’s Largest Floating Offshore Wind Farm

DOF Subsea has completed the installation of 19 suction anchors on the 88 MW Hywind Tampen floating offshore wind farm.

The transportation and installation of the suction anchors were carried out by the subsea AHTS vessel Skandi Skansen at the site located about 140 kilometres off the Norwegian coast, according to Semar AS, which provided the seafastening system.

Equinor plans to start towing the fully assembled wind turbines in early summer 2022 and complete the offshore work by the end of the year.

The first floating wind turbine has been already assembled, according to a social media post shared last month by Equinor’s Manager of Operations for Hywind Tampen, Ole Arild Larsen.

Once commissioned by the end of 2022, Hywind Tampen will be the largest floating offshore wind farm and the first floating wind farm to supply renewable power for oil and gas installations.

The wind farm is expected to cover about 35 per cent of the annual power needs on the Snorre A and B and Gullfaks A, B and C oil and gas platforms.
