Great Lakes Dredge & Dock Corporation has taken delivery of Acadia, a Jones Act-compliant subsea rock installation vessel built by Hanwha Philly Shipyard in Philadelphia, Pennsylvania.

The delivery marks a key step in Great Lakes Dredge & Dock Corporation’s expansion into the offshore energy sector, strengthening the company’s capability to support offshore infrastructure projects in the United States and overseas.

Following delivery, Acadia will mobilize for Equinor’s Empire Wind 1 project offshore New York. After completing that work, the vessel is expected to proceed directly to Ørsted’s Sunrise Wind project, also offshore New York, supporting offshore wind infrastructure development along the U.S. East Coast.

After the two U.S. projects, Acadia is expected to mobilize to Europe for subsea rock installation work for a major offshore wind developer, keeping the vessel utilized for most of 2027.

Lasse Petterson, President and Chief Executive Officer of Great Lakes Dredge & Dock Corporation, said the vessel marks an important point in the company’s offshore energy strategy. He added that Acadia strengthens the company’s subsea rock installation position in U.S. and international markets while supporting projects such as Empire Wind 1 and Sunrise Wind.

Built by Hanwha Philly Shipyard, Acadia is the first U.S.-flagged, Jones Act-compliant subsea rock installation vessel of its kind. The vessel is designed to transport and accurately place rock on the seabed to protect subsea infrastructure, including offshore wind turbine foundations and subsea cables.

Great Lakes Dredge & Dock Corporation is the largest provider of dredging services in the United States and has also carried out major international projects. The company operates about 200
