The Foreign Dredge Act of 1906 requires that all dredging in U.S. waters be performed by ships that are U.S.-built and owned, with a U.S. crew. It prevents bidding on projects by experienced, globally‐competitive dredging companies based in friendly countries like the Netherlands. As a result, U.S. ports pay far more to dredge than ports in Europe and elsewhere. A 2019 Congressional Research Service report found that due to the ban on outside competition the domestic market is served by only four U.S. companies that employ smaller, older and less efficient dredges than European counterparts. U.S. Army Corps of Engineers data shows that more than a third of its projects have only one bidder.
Once dredged, U.S. ports such as Wilmington are further limited by the 1920’s Jones Act, which requires that any cargo shipped between U.S. ports must be carried on a ship that is U.S.-built, flagged, owned and crewed. Like the 1906 Dredge Act, this confines intercoastal shipping to a limited fleet of aging ships, driving up the cost of moving goods within U.S. coastal waters.
