Overview
- A partnership announced Thursday between BW Ideol and construction group NGE creates a 50/50 Fos3F joint venture to develop a serial concrete foundation fabrication line in Fos‑sur‑Mer.
- The partners have jointly bid for a 30‑hectare site with 400 metres of quay at the DEOS platform in the Grand Port Maritime de Marseille and now await site allocation and detailed industrial planning.
- The planned facility is sized to make about 30 floating concrete foundations a year, roughly 500 MW of capacity annually, with the aim of supplying more than 200 foundations from 2030 to 2037.
- Fos3F retains up to €126 million of prior public support — up to €74 million from the EU Innovation Fund and up to €52 million via France’s C3IV scheme — and builds on a late‑2025 strategic materials agreement with Holcim for low‑carbon concrete.
- The project is pitched as a way to localise the floating‑wind supply chain for France’s AO10 programme, create about 1,300 direct jobs in Fos‑sur‑Mer and reduce foundation carbon intensity through local manufacturing and low‑carbon materials.
