New England offshore companies submit uniform layout proposal to Coast Guard

The five New England offshore wind leaseholders — Equinor, Mayflower Wind, Ørsted/Eversource and Vineyard Wind — announced a uniform turbine layout proposal submitted to the U.S. Coast Guard with 1 nautical mile (nm) spacing between wind turbines.

The companies issued the following joint statement:

“In response to feedback from key stakeholders, we have proposed to adopt a uniform turbine layout across our adjacent New England lease areas. This uniform layout has subsequently been proposed to the United States Coast Guard (USCG) for its review.

This uniform layout is consistent with the requests of the region’s fisheries industry and other maritime users. The proposed layout specifies that turbines will be spaced 1 nautical mile (nm) apart, arranged in east-west rows and north-south columns, with the rows and columns continuous across all New England lease areas. In addition, independent expert analysis provided to the USCG confirmed that this uniform layout would provide for robust navigational safety and search and rescue capability by providing hundreds of transit corridors to accommodate the region’s vessel traffic.

We look forward to continuing to work with the USCG, the Bureau of Ocean Energy Management, coastal states, the fisheries industry, and other stakeholders involved to ensure continued coexistence of every ocean user in the region, including offshore wind.”

A uniform layout reflects considerable written and oral public comments from New England maritime stakeholders and will allow mariners to safely transit from one end of the New England Wind Energy Area (NE WEA) to the other without unexpected obstacles.

The five New England offshore wind leaseholders’ proposal to the USCG addresses four principal concerns: (1) navigation safety; (2) the fisheries community’s request for uniform and consistent spacing between turbines throughout the NE WEA; (3) creation of distinct transit corridors; and (4) the facilitation of search and rescue operations conducted by both vessel and aircraft.
