Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger.
MV New Carissa was a freighter that ran aground on a beach near Coos Bay, Oregon, United States during a storm in February 1999 and broke apart. An attempt to tow the bow section of the ship out to sea failed when the tow line broke, and the bow was grounded again. Eventually, the bow was successfully towed out to sea and sunk. The stern section remained on the beach near Coos Bay. Fuel on board the ship was burned off in situ with napalm, but a significant amount was also spilled from the wreckage, causing ecological damage to the coast.
A fishing dredge, also known as a scallop dredge or oyster dredge, is a kind of dredge which is towed along the bottom of the sea by a fishing boat in order to collect a targeted edible bottom-dwelling species. The gear is used to fish for scallops, oysters and other species of clams, crabs, and sea cucumber. The dredge is then winched up into the boat and emptied. Dredges are also used in connection with the work of the naturalist in marine biology, notably on the Challenger Expedition.

The Mafuta is a diamond-mining ship owned and operated by De Beers in the western coast of South Africa. Built in 1983 as Dock Express 20 for Dock Express Shipping, the semisubmersible, multirole, heavy-lift vessel was converted to the world's largest cable layer in 1993. In 2005, she was purchased by De Beers, and converted to a subsea diamond-mining ship by A&P Tyne over the course of 11 months. The ship's new name, Peace in Africa, may have implied that it was providing an alternative to blood diamonds. In 2013, still under ownership of De Beers Marine Namibia, the vessel was renamed to MV Mafuta.
