Geophysical & Geotechnical Survey Update

Summer and Fall 2021

Multiple vessels will conduct geophysical & geotechnical (G&G) surveys to characterize the ocean floor conditions within federal and state waters during the summer and fall 2021.

The survey area and vessel operating schedule are shown in the figures below.

No final decisions on site locations for project facilities will be made until a full routing analysis has been completed.

Mayflower Wind recognizes that responsible development requires early, transparent, and continuous engagement and collaboration with the commercial and recreational fishing industries.

Co-existence of offshore wind and ocean users must be backed by a strong commitment to safety and responsible operations. This includes navigation safety in and around the offshore lease area for all mariners, including fishermen, during the development, construction and operations of the project. We are committed to clearly communicating our marine operations to our fellow ocean users, community members, and other maritime partners.

  • Mayflower Wind worked with federal agencies, fishermen, and offshore wind developers to establish the Responsible Offshore Science Alliance (ROSA) to advance regional research and monitoring of fisheries and offshore wind interactions in federal waters through collaboration and cooperation.  
  • Mayflower Wind has contracted two Fisheries RepresentativesMassachusetts Lobstermen’s Association (MLA) and the New Bedford Port Authority (NBPA), to collaborate on initiatives that minimize impacts to fisheries in the project area.
  • Survey vessels in the lease area have on board Fisheries Representatives to identify and appropriately manage any issues.

Fisheries Liaison Officer

Mayflower Wind is pleased to welcome Joel Southall as the project’s Fisheries Liaison Officer. In this role, Joel will serve as the liaison between the fishing community and Mayflower Wind. He’ll be listening to mariners and sharing project updates and activity information to strengthen communication and collaboration.

As social distancing guidelines allow for more in-person interactions, Joel will be a regular presence in the field, including monthly Port Hours in New Bedford, Massachusetts and Narragansett, Rhode Island. If you have questions or concerns, please contact Joel at 617-817-4682 or
