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 mi. south of Martha’s Vineyard, Massachusetts, 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 a passive acoustic monitoring sensor were deployed from the Geosea DP2 multipurpose support vessel.

The acquired data are now being processed for delivery in November.
