OffshoreWIND.biz reports that initial refurbishment and hall-construction work began in mid-2026 and is scheduled for completion by early 2027. Further investment is planned during 2027–2028, and EEW SPC has acquired a neighbouring industrial site for raw-material storage.
MetalMate summary of the linked evidenceCommercial context
Analysis: The upgrade would increase Rostock’s maximum monopile diameter from 10 metres to 12 metres, broadening its capability for larger offshore wind foundations. The additional storage site also indicates a larger raw-material and production footprint.
MetalMate analysis- Planned maximum unit size: 12 metres in diameter and 3,000 tonnes from Q2 2028, according to OffshoreWIND.biz.
- Current stated maximum diameter: 10 metres.
- Stated annual plant capacity: 200,000 tonnes under normal operating conditions.
- Investment: tens of millions of euros across machinery, infrastructure and space optimisation.
- Initial works: started in mid-2026 and scheduled for completion by early 2027.
- Further investment is planned during 2027–2028 to enable larger-monopile production.
Watch whether the initial works finish by early 2027, whether the planned 2027–2028 investments proceed on schedule, and whether 12-metre, 3,000-tonne monopile capability becomes available from Q2 2028 as planned.
