Talks are under way that could see Equinor name Port of Coeymans on the Hudson River as its preferred site in upstate New York for manufacturing 60-80 concrete gravity base foundations (GBFs) for its 816MW Empire Wind offshore project.

The GBFs would be floated out to the installation site 15-30 miles (24-48km) south of Long Island using low-cost tug boats, before being sunk in 20-40-metre waters to the ocean floor, where gravity alone will keep them anchored to the seabed.
