BW Ideol teams up with NGE to mass produce concrete floaters

As part of the agreement, the companies will hold equal shares in the Fos3F project, initiated by BW Ideol, the aim of which is to develop a fabrication line for floating foundations in Fos-sur-Mer at Grand Port Maritime de Marseille.

BW Ideol and NGE will jointly continue development of the fabrication line, which will be sized to produce approximately 30 floaters per year, equivalent to an annual capacity of around 500 MW.

The companies have jointly submitted a bid to the Grand Port Maritime de Marseille’s call for projects for the allocation of 30 hectares of land backed by 400 m of quay in Fos-sur-Mer.

The agreement follows BW Ideol securing €126M in public funding for Fos3F, including a grant of up to €74M, under the European Union’s Innovation Fund, and a tax credit of up to €52M under the C3IV green industry investment scheme.

NGE brings to the partnership expertise in the design and delivery of complex infrastructure projects, particularly in civil engineering.

The partnership is being formed as the French government launches the AO10 tender, which brings cumulative floating wind development in France to more than 5 GW, including 3.7 GW on the Mediterranean coastline. “It helps secure delivery this ambition and the supply of more than 200 floating foundations between 2030 and 2037,” said BW Ideol. “It also underpins the creation of a new industrial sector in France, with more than 1,300 direct jobs anticipated in Fos-sur-Mer.”

BW Ideol said the partnership also builds on an agreement signed with the Holcim group in December 2025 for the supply of innovative materials, including low-carbon concrete.
