Great Lakes Dredge & Dock Adds Subsea Rock Installation Vessel for Offshore Wind Projects

  • Great Lakes Dredge & Dock took delivery of the Acadia, a Jones Act-compliant subsea rock installation vessel, on June 25, 2026.
  • The vessel will first work on Equinor’s Empire Wind 1 project and then Ørsted’s Sunrise Wind project off New York.
  • Acadia is expected to deploy in Europe for a major offshore wind developer in 2027.
  • Constructed by Hanwha Philly Shipyard, Acadia is the first U.S.-flagged vessel of its kind.

Great Lakes’ acquisition of the Acadia underscores its strategic pivot toward offshore wind infrastructure, a rapidly growing sector driven by energy security and decarbonization goals. The vessel’s deployment on high-profile projects like Empire Wind 1 and Sunrise Wind positions Great Lakes as a key player in protecting subsea assets critical to renewable energy development.
