Dredges Built in the U.S. Since WWII
Until 1960, most of the dredging of U.S. ports and waterways was done by the Corps of Engineers, using their own equipment. In the early 1960s, however, the Merchant Marine Act was modified to allow private-sector contractors to take up the load: in addition, the Jones Act was modified to include dredge spoil. As a result, all the new private-sector dredges had to be US-built as well as US-operated. These changes resulted in all but one of the Corps' dredges being retired and there was a boom in private-sector dredge construction in the 1970s and 80s. The table below lists all the large dredges built since WWII by year built.
