Great Lakes Dredge & Dock Corporation Signs Contract with Philly Shipyard, Inc. to Build the First Jones-Act Compliant Subsea Rock Installation Vessel for U.S. Offshore Wind

Great Lakes Dredge & Dock Corporation, the largest provider of dredging services in the United States announced today that the Company has signed a contract with Philly Shipyard, Inc (OSE: PHLY) to build the first U.S.-flagged Jones Act-compliant, inclined fallpipe vessel for subsea rock installation. This vessel will service America’s growing offshore wind energy industry and help reach the Biden administration’s ambitious 30 GW of offshore wind goal by 2030.

“This contract, valued at approximately $197 million, marks a milestone for our company, the U.S. offshore wind industry and our nation,” said Lasse Petterson, Great Lakes Dredge & Dock’s President and Chief Executive Officer. “Offshore wind will play a crucial role in helping the U.S. meet its decarbonization and clean energy goals. The unique, technologically advanced vessel we are constructing is an essential step towards building the marine infrastructure required for this new industry, which holds so much promise for our nation economically and environmentally.”

This Great Lakes Dredge & Dock vessel will be U.S. owned, U.S. built, U.S. operated and crewed by American union workers, and will meet all conditions of the Jones Act. The vessel will transport and strategically deposit loads of rock on the seabed, laying scour protection for offshore wind farm foundations, cables and other structures. The ship will have an overall length of 140.5 meters (461 feet) and a breadth of 34.1 meters (112 feet). Further, the vessel is expected to help spur additional job growth and regional economic opportunities through the creation of a U.S.-based rock supply chain network, which will be needed to supply subsea rock installation activities, from quarries in states along the East Coast.

Eleni Beyko, Great Lakes Dredge & Dock’s Senior Vice President, Offshore Wind, commented, “World-renowned engineering firm Ulstein Design and Solutions B.V. was commissioned by the Company to design the vessel using state-of-the-art technology, equipment, and automation. The design was reviewed and approved by the American Bureau of Shipping (“ABS”) and will be built with best-in-class safety and low emissions standards (LEV, Sustain2), EPA Tier 4 engines and plug-in capability to obtain power from shore while loading. The vessel will be able to run on biofuel which reduces the ship’s CO2 footprint and it will be equipped with advanced active emissions control technology to reduce NOx emissions to a minimum. The installed battery pack will shave peak loads to reduce fuel consumption and corresponding emissions. The vessel is expected to be sea-ready by Q4 2024, to coincide with major offshore wind project construction timelines previously announced.”

As the leading U.S. dredging company and with more than 130 years’ experience and expertise in dredging, marine engineering, specialized vessel design and safe offshore operations, Great Lakes Dredge & Dock believes the company is optimally positioned to make the business pivot into the offshore wind energy industry. The Company brings best practices to all the projects it undertakes, employing among the industry’s highest safety standards and quality control protocols.

“With this newbuild vessel purpose built to meet the needs of the U.S. offshore wind industry, we are essentially harnessing the best practices to create a new dimension to our legacy and help make history for our country,” concluded Petterson.
