Up to £250m will be invested to beef up the domestic supply chain as part of sector deal commitments to boost local content.
Offshore Wind Industry Council members, supply chain companies and regional bodies such as local enterprise partnerships, councils and development agencies will provide a total £100m to set up the Offshore Wind Growth Partnership.
The partnership will target regions of the UK deemed to be of strategic importance such as north-east England, East Anglia, Humberside and the Solent.
OWIC said the partnership will be delivered by the Offshore Renewable Energy Catapult and will be launched before the summer.
A further £150m will be spent by developers in the local supply chain as the UK builds 30GW of installed capacity by 2030, a 22GW construction spree to add to 7.9GW currently online, OWIC said.
BEIS said the partnership will help ensure UK companies in the identified areas “will continue to be competitive and are leaders internationally in the next generation of offshore wind innovations in areas such as robotics, advanced manufacturing, new materials, floating wind and larger turbines.”
