Under the MoU, Able and Dong Energy will work closely to progress significant development plans.
Able said that the memoranda represents a major step forward in creating a cluster of companies to help achieve cost-effective production levels while securing the long-term offshore wind power generation future.
Local Growth Minister James Wharton said: "This signing is another significant step for the Humber Enterprise Zone and further shows that firms are realizing the benefits this Zone offers for boosting their business and wider contribution to the Northern Powerhouse.
"This agreement will help the UK supply chain develop in key areas like towers manufacturing and ensure the UK remain market leaders in this sector.
Planned to be built at Killingholme, near Immingham, North East Lincolnshire, the proposed facility will be used to support the construction and installation of offshore wind farms.
The 800-acre energy park comprises facilities, including quays designed to meet the needs of the industry, and is expected to create 4000 jobs.
Able executive chairman Peter Stephenson said: "AMEP provides a unique opportunity to operate on a scale that can deliver the cost targets which are needed by the industry and we are delighted that this has been recognized by the major operator.
"After all the real prize is to secure UK based production facilities that serve both the domestic market with the added potential benefit of exporting to other European markets.
"What we now need to see are further investment decisions made as quickly as possible and that requires continued Government support which can ensure that the Humber — and the UK as a whole — is able to benefit from using the wind resources of the North Sea as a major contributor in the transition to a carbon-free economy."
