WindFloat Atlantic – the world’s first semi-submersible floating offshore wind farm – has now been on-line for 3 years and continues to interrupt its personal energy output information.

The 25 megawatt (MW) WindFloat Atlantic undertaking ended 2023 with an electrical energy manufacturing of 80 gigawatt hours (GWh), surpassing 2022’s output of 78 GWh. It provides energy to greater than 25,000 households and avoids 33,000 tons of carbon dioxide.

The offshore wind farm sits 20 km off the coast of Portugal within the municipality of Viana do Castelo, north of Porto. It contains three 8.4 megawatt (MW) Vestas wind generators that sit on semi-submersible, three-column floating platforms anchored by chains to the seabed. A 20 km lengthy (12.4 mile-long) cable connects it to an onshore substation.

It’s a three way partnership between Spanish renewable firm EDPR, international vitality agency ENGIE, Spanish vitality agency Repsol, and California-headquartered floating offshore wind agency Precept Energy.

WindFloat Atlantic was related to the grid on the finish of 2019 and commissioned in 2020. It has an operations and upkeep base within the port of Viana do Castelo, the place the crew receives the wind farm’s data in real-time to allow them to tackle points instantly. Onsite intervention might be advanced, because of opposed climate and sea circumstances within the space the place it’s sited.

WindFloat Atlantic was sturdy within the face of Storm Ciarán, which tore by means of Europe on the finish of October and starting of November final yr, because of a strong jet stream that got here in from the Atlantic. The floating wind farm weathered wave heights of 20 meters (66 toes) and wind gusts as much as 139 km/hr (86 mph).

Precept Energy, which additionally labored on Scotland’s Kincardine, the world’s largest floating offshore wind farm, explains what makes semi-submersible floating offshore wind distinctive:

The WindFloat has been developed particularly to attain distinctive stability efficiency, whereas decreasing structural weight, and simplifying logistics throughout set up and operation.

The digital pitch- and yaw-free efficiency within the offshore surroundings permits the usage of present industrial offshore wind generators, positioned at one of many columns, with solely minor modifications to regulate software program.
