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.

Data story: Mapping the global offshore wind pipeline from 75 GW installed to 380 GW in development

Offshore wind installations grew 18% year-over-year in 2024 to reach 75 GW globally, with China adding 40% of new capacity. Floating wind projects in development surged from 6 GW to 60+ GW between 2021 and 2025, concentrated in the UK, Norway, South Korea, and the U.S. West Coast. This data story tracks capacity pipelines, auction prices, and regional momentum shifts.

Deep dive: Offshore wind and floating wind scaling challenges from supply chains to grid integration

Offshore wind faces critical bottlenecks: only 4 installation vessels worldwide can handle 15+ MW turbines, port infrastructure gaps delay projects by 12-18 months, and floating wind LCOE remains 2-3x higher than fixed-bottom at $100-$150/MWh. This deep dive examines supply chain constraints, manufacturing scale-up, and the policy levers accelerating cost reduction.

Explainer: Offshore wind and floating wind technology reshaping global energy markets

Global offshore wind capacity reached 75 GW in 2024 with 380 GW in development pipelines, while floating wind — currently at just 250 MW installed — unlocks 80% of ocean wind resources in waters deeper than 60 meters. This explainer covers fixed-bottom vs floating foundations, turbine scaling to 15+ MW, and the economics driving $100+ billion in planned investment.

Fixed-bottom vs floating offshore vs onshore wind: costs, capacity factors, and deployment trade-offs

Onshore wind delivers the lowest LCOE at $26-$50/MWh but faces land constraints, fixed-bottom offshore achieves higher capacity factors (45-55%) at $60-$100/MWh, and floating platforms unlock deeper water sites at $100-$150/MWh with costs projected to fall 40-50% by 2030. This comparison evaluates siting flexibility, grid value, and investment risk across all three configurations.
