Great Lakes Awarded Installation Contract for East Coast Offshore Project


Great Lakes Dredge & Dock Corp. has been awarded a third rock installation contract to perform subsea rock cable protection on a wind project off the U.S. East Coast. 

For project execution, Great Lakes will use a subsea rock installation vessel, the Acadia, currently under construction. The project scope includes procurement of rock from the company’s U.S. supply chain, transportation to and from the project site, and subsea rock installation to support the wind farm’s infrastructure. 

The company’s prior contracts have been for subsea rock installation for foundation stabilization, and this contract represents a new utilization for its planned vessel.

“This project award further confirms Great Lakes’ ambition and leadership to support the emerging U.S. offshore wind industry and we look forward to expanding our participation in this market over the coming years,” says Lasse Petterson, Great Lakes’ president and CEO.

“This award further solidifies Great Lakes’ entry into the U.S. offshore wind market with another major project award,” adds Great Lakes’ Eleni Beyko. “We are pleased to support the United States in building a more sustainable future and to continue to mature and enable our U.S. rock supply chains.  Our goal remains to contribute to building the U.S. offshore wind industry, while creating local employment and U.S. economic activity.”

The project remains subject to the client’s final investment decision, with operations expected to commence in 2025 and continue into 2026.
