Haizea Wind Group has completed delivery of a set of monopile foundations destined for Ørsted's Hornsea 3 offshore wind project in the North Sea, with the Spanish manufacturer describing the structures as the largest monopiles ever produced in Southern Europe.

Record-Scale Components from Southern Europe

The monopiles delivered by Haizea Wind Group represent a notable manufacturing milestone for the region, with the company characterizing them among the largest offshore wind foundations built anywhere in Europe. The components will serve as the structural bases for turbines at Hornsea 3, the offshore wind development Ørsted is constructing in the North Sea with a planned generating capacity of 2.9 gigawatts.

Monopiles are the steel cylindrical foundations driven into the seabed that support offshore wind turbines. As turbine sizes have grown substantially in recent years, the dimensions of the foundations required to anchor them have scaled accordingly, demanding increasingly sophisticated manufacturing capabilities from suppliers.

Hornsea 3's Place in Offshore Wind Development

At 2.9 GW, Hornsea 3 is among the largest offshore wind projects under development globally. The project is part of Ørsted's broader Hornsea zone in the North Sea off the eastern coast of England, a development zone that has already produced operating wind farms at significant scale with Hornsea 1 and Hornsea 2.

The delivery of the monopile foundations marks a concrete step in the physical buildout of Hornsea 3's infrastructure, with large foundation components typically representing some of the earliest major hardware milestones in offshore wind construction timelines.

Supply Chain Significance

The Haizea delivery underscores the role that Southern European manufacturers are beginning to play in supplying components for major North Sea wind projects. Haizea Wind Group, based in the Basque Country in northern Spain, has positioned its facility as capable of producing foundation structures at the scale demanded by the latest generation of offshore wind turbines.

The ability to manufacture record-scale monopiles outside of the traditional cluster of Northern European suppliers reflects ongoing investment in offshore wind manufacturing capacity across the continent, as European governments and developers work to expand the supply chain needed to meet ambitious renewable energy targets.

Producing foundations of this scale involves significant logistical as well as manufacturing challenges, given the size and weight of the structures involved in transport from fabrication facilities to staging ports and ultimately to offshore installation vessels.
