Hywind Tampen is located around 140 kilometers (86.9 miles) off the coast of Norway, in depths ranging from 260 to 300 meters.
Seven of the wind farm’s turbines are slated to come on stream in 2022, with the installation of the remaining four taking place in 2023. When complete, Equinor says it will have a system capacity of 88 megawatts.
Equinor said Hywind Tampen was expected to meet around 35% of the Gullfaks and Snorre fields’ electricity demand. “This will cut CO2 emissions from the fields by about 200,000 tonnes per year,”
Unlike bottom-fixed structures, floating wind farms attach turbines to floating structures held in an area by mooring lines and anchors. Many models borrow from offshore drilling rig designs and use motion controllers to optimize power production while reducing structural stress.
Hywind Tampen’s turbines in particular are installed on floating concrete structures with joint mooring systems. Their stability is provided by gravity. Another design uses semi-submersible floaters that rely on buoyancy instead.
These constructions allow wind farms to be placed in deeper waters, expanding the energy-producing area.
While wind is a renewable energy source, Hywind Tampen will be used to help power operations at oil and gas fields in the North Sea. Equinor said Hywind Tampen’s first power was sent to the Gullfaks oil and gas field.
