Empire Offshore Wind, a joint venture between Equinor and BP, has hired engineering consultancy firm COWI to design the wind turbine foundations for Empire Wind 1 and 2 off the coast of Long Island, New York. Empire Wind will use 15-MW wind turbines to generate more than 2 GW of renewable energy, with a total capacity of more than 2 GW. Over 100 professionals from COWI will work on all areas of the wind turbine foundation design, from the tower interface to seabed attachment – including steel, geotechnical, and electrical design, as well as engineering support for fabrication, transportation, and installation.
The 80,000-acre complex is located at water depths ranging from 65 to 131 feet. The project requires precise engineering of 138 foundations with diameters of 30 feet and lengths of up to 330 feet. “We’re ecstatic to be partnering with Equinor and BP on one of the country’s largest offshore wind projects,” said Greg Matzat, COWI’s Market Director for Offshore Wind & Renewables.
In addition to marine terminals, site evaluations, geotechnical investigations, turbine and offshore substation foundation designs, the company has obtained numerous more projects on both coasts. Since 1980, COWI has been designing wind turbine foundations in Europe and Asia, with over 1,200 turbine foundations of their design deployed globally.
