“The people at ThayerMahan are remarkable inventors, and their technology will help us reduce any disruption offshore wind might have on North Atlantic marine life and the local fishing fleets.”

The services that ThayerMahan and Ørsted/Eversource would explore include but are not limited to marine mammal monitoring; environmental monitoring from fixed and mobile systems; metocean measurements and weather forecasting; marine traffic and wind project vessel traffic monitoring; seabed survey and inspections of undersea cable and monopile systems during construction and operations; Balance of Plant services including operations and maintenance of wind turbine generators, monopile foundations, transition pieces, onshore substations, and array and export cable surveys; and land-based real estate and construction consulting services including permit assist, land/purchase assist, zoning and entitlement assist, construction management and monitoring.

“Ørsted and Eversource have been fantastic partners. We are glad to be part of their plans to fully utilize our local businesses, which have some of the best minds in the world,” said ThayerMahan CEO Mike Connor.
