Great Lakes Dredge & Dock Corporation (GLDD), the largest provider of dredging services in the United States, has announced the signing of the first ever subcontract for procurement of rock for a U.S. offshore wind farm with Carver Sand & Gravel LLC (“Carver”), a U.S. quarry in the state of New York.

Through this subcontract, Great Lakes will use rock produced in the State of New York to provide scour protection for offshore wind turbine foundations, and substations at Equinor (NYSE: EQNR) and bp’s (NYSE: bp) Empire Wind I and Empire Wind II wind farms.

The rock will be quarried locally, transported to the quayside on the Hudson River, and loaded onto Great Lakes’ rock installation vessel, the Acadia, which will sail to the wind farms to install the rock starting in 2025.

Great Lakes and Carver will be developing the first U.S. rock supply chain for offshore wind, including the quarry producing the rock, the stockpiling and transportation of the rock to the quayside, the port and loading facilities that will load the rock installation vessel, and other facilities along the Hudson River that will help guide the vessel in the riverway.
