Bleichen, Museum ship at Hansa Harbor in Hamburg, Germany

MS Bleichen is a preserved cargo ship from the postwar era docked at the Bremer Kai in Hamburg harbor, now open as a museum vessel. The ship is about 280 feet (85 m) long and shows the layout of a multipurpose freighter, with cargo holds, deck equipment, and crew quarters.

Built at the Nobiskrug shipyard in Rendsburg for the Hamburg shipping company H. M. Gehrckens, the Bleichen entered service on 28 August 1958 and carried paper from Finland to Germany until 1970. Renamed Canale Grande by an Italian owner, then Arcipel after a Turkish shipowner bought it in 1979, it sailed from 1994 to December 2006 as Old Lady hauling bulk cargo in the Black Sea. The Hamburg Maritime Foundation bought it in 2006 for 450,000 euros raised through donations; after a shipyard stay in Turkey it arrived in Hamburg on 30 January 2007 and was renamed Bleichen on 27 April 2007.

The ship is named after the Bleichen, an old Hamburg street, as is its sister ship Borgesch. The Gehrckens line (H.M.G.) traded with Scandinavia, so the Bleichen was built to a high ice class for year-round Baltic voyages. On deck, the white letters "H.M.G." recall the original owner.

The ship is moored at the Bremer Kai near the harbor museum, and the surrounding area is flat and easy to walk around. Once on board, some areas require climbing steep ladders, so comfortable footwear is a good idea.

The original diesel engine by Klöckner-Humboldt-Deutz is still on board and is one of the few surviving examples of that propulsion technology from the late 1950s. Much of the original steering and navigation equipment has also been kept, making this one of the more complete surviving examples of its kind.
