Great Lakes Dredge & Dock Corporation has taken delivery of Acadia, a Jones Act-compliant subsea rock installation vessel, from Hanwha Philly Shipyard in Philadelphia. The vessel will first mobilize to work on Equinor's Empire Wind 1 project offshore New York, then proceed to Ørsted's Sunrise Wind project, also offshore New York, before heading to Europe for a major offshore wind developer, keeping it utilized for the majority of 2027.
