COWI will deliver a design for wind-turbine foundations for Empire Wind 1 and 2 projects. With an anticipated generation capacity of more than 2 GW of renewable power, the project will use 15-MW wind turbines and is expected to play a big role in meeting New York State’s 70 percent renewable energy goal by 2030. More than 100 experts will work on the design, from the tower interface to the seabed fastening, including steel, geotechnical, and electrical design for the project as well as engineering support for fabrication, transportation, and installation.

The development spans 80,000 acres and is in water depths ranging from 65 to 131 feet. The project calls for the detailed engineering of 138 foundations with diameters of approximately 30 feet and lengths up to 330 feet.

“We’re thrilled to be supporting Equinor and bp on one of the largest offshore wind projects in the U.S.,” said Greg Matzat, COWI’s market director, Offshore Wind and Renewables. “It’s developments like this that really excite us, a complex engineering project, at the head of the development of a new industry in the U.S., that has huge social benefits and will help New York and the U.S. achieve their renewable energy goals. The offshore wind industry in the U.S. is booming, and we see great potential here for our engineers to continue providing innovative solutions for our clients.”

The announcement adds Empire Wind to COWI’s offshore wind portfolio in the U.S., with COWI’s seven-year contract for Vineyard Wind in Massachusetts. The company has also secured projects on both coasts with respect to marine terminals, site assessments, geotechnical analysis, and turbine and offshore substation foundation designs. COWI has engineered wind solutions in Europe since 1980 and has more than 1,200 turbine foundations of its design installed worldwide.
