June 1, 2020 — The offshore wind power industry cleared one of its last remaining bureaucratic hurdles Wednesday with the release of a long-awaited report from the Coast Guard that essentially agrees with an industry proposal on turbine layout.
The Coast Guard’s Massachusetts and Rhode Island Port Access Route Study has concluded that turbines should be spaced 1.2 miles apart and oriented in the same direction across seven offshore wind lease areas totaling around 1,400 square miles south of Nantucket.
Concerned with vessel safety and the ability to maneuver while fishing, some fishermen and industry groups sought larger lanes, as wide as 4 miles, to transit to fishing grounds, but the five wind power companies holding the leases said that would force them to crowd turbines outside the travel lanes, making it less safe to navigate and fish.
The offshore wind leaseholders — Equinor, Mayflower Wind, Orsted/Eversource and Vineyard Wind — had been concerned that some of the layouts proposed by other stakeholders could reduce the number of turbines and power generation. The increasing efficiency and power capacity of newer turbines have alleviated some of that concern.
