TerraSond Completes First Geophysical Survey for Mayflower Wind

TerraSond, an Acteon company, has completed a high-resolution geophysical survey for Mayflower Wind, a joint venture between Shell New Energies US LLC and EDPR Offshore North America LLC. The two-month campaign, which began in July 2019, surveyed an area, 20 miles south of Martha’s Vineyard, Massachusetts, USA, that can support up to 1,600 MW of offshore wind. The wind farm is scheduled to deliver energy in the mid-2020s and has the potential to power up to 680,000 homes.



The project is TerraSond’s first with Mayflower Wind."]TerraSond acquired high-resolution geophysical data using a complete suite of equipment in water depths from 35 to 65 m. A sub-bottom profiler, a medium-penetration seismic system, a side-scan sonar, a multibeam echosounder, a magnetometer and passive acoustic monitoring sensor were deployed from the Geosea DP2 multipurpose support vessel. The acquired data are now being processed for delivery in November.

“We used our offshore-wind-sector expertise to deliver a successful geophysical survey for Mayflower Wind,” says Pedro Regino, TerraSond project manager. “As always, we put safety and the environment first. The environmental monitoring plan, which included protected species observers and passive acoustic monitoring operators, resulted in no environmental impacts or harm to marine life, successfully meeting Mayflower Wind’s safety ambitions.”

“The execution of this important survey work displayed the core values of Mayflower Wind: it was done safely, environmentally consciously and utilized a key local port: New Bedford,” says Mayflower Wind President John Hartnett. “Completing this survey was a critical step for Mayflower Wind.”
