In 2020 Global Maritime were awarded the Marine Warranty Survey contract for the Hywind Tampen floating offshore wind project by Equinor.

Hywind Tampen is an 88 MW floating wind power project intended to provide electricity for the Snorre and Gullfaks offshore field operations in the Norwegian North Sea. It will be the world’s first floating wind farm to power offshore oil and gas platforms. Once complete it be the world’s largest floating offshore wind farm and an essential step in industrialising solutions and reducing costs for future offshore wind power projects.

The floating wind farm will consist of 11 wind turbines based on one of Equinor’s floating offshore wind technologies, Hywind. The wind farm will have a combined capacity of 88 MW and 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. In periods of higher wind speed this percentage will be significantly higher.

MWS works commenced in April 2020 with Global Maritime attending the following operations:

  • Out of dock operations at Stord (the initial 20m of concrete substructures (CSS) build at Aker Solutions dry dock) and towing to Dommersnes for further slip forming up to 107m
  • Safe mooring operations at Dommersnes (3 barges connected to floating quay)
  • Solid ballast filling operations at Dommersnes
  • Bridle wire installations

In 2022 the Global Maritime MWS team will support the towing activities of the 11 CSS from Dommersnes to the assembly site at Gulen. Additionally, interim transports of FWT components (tower sections, nacelle, blades etc.) shipped from Spain, Germany, Denmark, as well as the mooring spread approval at Gulen for further FWT assembly. The FWT components will be assembled by use of a ring crane (onshore), supplied by Mammoet. A spacer barge will be utilised for the assembly, positioned between the FWT and ring crane. The final element includes towage to the offshore location for installation.
