Able Marine Energy Park, located on an 800 acre site on the South bank of the Humber, will provide a supply, assembly and installation base for projects in the North Sea.
Trade body RenewableUK says the scheme could create upto 4,000 jobs in the cleantech industry.
Deputy chief executive, Maf Smith, said: “This is a real cause for celebration in this season of good cheer, not just for Able Marine Energy Park, but for the whole offshore wind sector in the UK. It is testament to a continuing sense of long term confidence in the offshore wind sector, which is at the very heart of our green energy future.
“This announcement could be the catalyst for further investment in the region. Alongside recent announcements of investment in Grimsby, this shows how offshore wind is bringing real opportunities to regions like the Humber.
“Offshore wind, and the supply chain it is building, could create tens of thousands of green-collar jobs to coastline communities in areas where they’re needed most.”
