The Block Island Wind Farm is located approximately 15 miles away from the Rhode Island mainland in approximately
90 feet of water. Deepwater Wind has executed a multi-year effort to map and sample the ocean floor in the Project
Area, requiring vessels and expertise from across the U.S. Surveys included:
• 2009 Geophysical Reconnaissance - - Initial surveys necessary to evaluate critical issues and identify avoidance
areas.
• 2009 Geotechnical Boring - - Drilling of eight deep holes necessary to assess suitability of sea floor for supporting
turbine locations
• 2010 Sediment Profile Imaging - - Necessary to determine constructability and environmental impacts
• 2011 Geophysical Program - - Detailed geophysical and archaeological surveys in compliance with federal (BOEM)
requirements
• 2012 Geotechnical Program - - Vibracore samples throughout survey area to assess near surface structural and
thermal characteristics of the ocean floor.

Important Items to Discuss
• “Envelope” Permitting
• Potential for Industry LOA re: DP vessel use, HRG
surveys
• 24/7 survey and pile driving
• Goal of effective real-time monitoring
