Case study: Hywind Tampen — lessons from the world's largest floating wind farm powering offshore oil platforms
Equinor's 88 MW Hywind Tampen project in Norway became the world's largest floating wind farm in 2023, using 11 Siemens Gamesa 8 MW turbines on spar-buoy foundations to power five North Sea oil and gas platforms. The project reduced platform emissions by 200,000 tonnes CO₂/year but faced 30% cost overruns and 18-month delays, offering critical lessons for the floating wind industry.
