Norway’s Ministry of Petroleum and Industry has approved the plans for development and operation of the Hywind Tampen wind farm which will mean the Snorre and Gullfaks platforms will be the first platforms in the world to receive power from a floating offshore wind farm.
The wind farm will consist of 11 wind turbines based on the Hywind wind farm concept developed by Equinor. The 8MW turbines will have a total capacity of 88MW and meet about 35 percent of the annual power demand of the five platforms Snorre A and B and Gullfaks A, B and C. The wind farm will be located around 140 kilometers from shore, between the Snorre and Gullfaks platforms, at a water depth of 260 to 300 meters.
The Siemens Gamesa SG 8.0-167 DD turbines will be mounted on floating concrete spar substructures with shared anchors supplied by Kvaerner. 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 turbines will be connected in a loop by a 2.5 kilometer-long, 66 kV dynamic inter-array cable system. Read on.
