Great Lakes Dredge & Dock Takes Delivery of Acadia, a State-of-the-Art Subsea Rock Installation Vessel
Houston, June 25, 2026 (GLOBE NEWSWIRE) — Great Lakes Dredge & Dock Corporation (“Great Lakes” or the “Company”), the largest provider of dredging services in the United States, today announced it has taken delivery of Acadia, a cutting-edge Jones Act-compliant subsea rock installation vessel, from Hanwha Philly Shipyard in Philadelphia, Pennsylvania.
The delivery of Acadia marks a significant milestone in Great Lakes’ strategic expansion into the offshore energy sector and reinforces the Company’s commitment to supporting U.S. and international energy security ambitions. Following delivery, Acadia will mobilize to begin work on Equinor’s Empire Wind 1 project offshore New York. Upon completion, the vessel is expected to proceed directly to Ørsted’s Sunrise Wind project, also located offshore New York, supporting the buildout of offshore wind infrastructure along the U.S. East Coast. Upon completion of the two U.S. projects, the Acadia will mobilize to Europe to begin rock installation for a major offshore wind developer, keeping the Acadia utilized for the majority of 2027.
“Taking delivery of Acadia represents a transformative moment for Great Lakes and underscores our dedication to installing and protecting domestic and international offshore energy infrastructure,” said Lasse Petterson, President and Chief Executive Officer of Great Lakes Dredge & Dock Company. “This highly specialized vessel positions us at the forefront of subsea rock installation in the U.S. and international markets and enables us to play a critical role in major projects such as Empire Wind 1 and Sunrise Wind that offer a reliable, affordable, clean energy solution to the State of New York.”
Constructed by Hanwha Philly Shipyard, Acadia is the first U.S.-flagged, Jones Act-compliant subsea rock installation vessel of its kind. Designed with state-of-the-art technology, the vessel is equipped to safely and efficiently transport and precisely place rock materials on the seabed to protect subsea infrastructure, including cables and foundations for offshore wind turbines.

GLDD Coastal & Dredging Laboratory at Texas A&M University
An endowment from Great Lakes Dredge & Dock Company (GLDD) established the GLDD Coastal & Dredging Laboratory (CDL) in 2022. The CDL replaces the old Center for Dredging Studies (CDS) which was established in 1968 as a result of conferences held between educators, representatives of the dredging industry, manufacturers, and officials at Texas A&M University. The laboratory is located in the Department of Ocean Engineering and is supported by gifts and research grants from the dredging industry and the government and continuing education courses.
In addition to research and industrial testing, the lab’s activities include teaching university courses and providing annual seminars and short courses concerning advances in dredging engineering technology. The lab sponsors the annual dredging engineering short course. The Coastal and Dredging Laboratory also actively generates reports, participates in regional, national and international dredging conferences and has a cutter suction dredge simulator.
