Additionally, the vessel’s ability to cost-effectively deepen and maintain navigable waterways will bolster the United States’ competitive position in world trade, as the nation’s ports move forward with deepening plans to accommodate the larger vessels, which will sail through the expanded Panama Canal.

Great Lakes Dredge also owns and operates the largest and most diverse fleet in the U.S. industry, comprised of over 200 specialized vessels.
