Screw-driven steamships generally carry the ship prefix "SS" before their names, meaning 'Steam Ship' (or 'Screw Steamer' i.e. 'screw-driven steamship', or 'Screw Schooner' during the 1870s and 1880s, when sail was also carried), paddle steamers usually carry the prefix "PS" and steamships powered by steam turbine may be prefixed "TS" (turbine ship).
While steam turbine-driven merchant ships such as the Algol-class cargo ships (1972–1973), ALP Pacesetter-class container ships (1973–1974) [37] [38] and very large crude carriers were built until the 1970s, the use of steam for marine propulsion in the commercial market has declined dramatically due to the development of more efficient ...

In 1999, the ship was sold to Lower Lakes Towing and renamed Saginaw. The ship is currently ...
On July 30, 1995 the steamship SS William G. Mather was dedicated as an American Society of Mechanical Engineers National Historic Mechanical Engineering Landmark for its 1954 installation of a single marine boiler and steam turbine engine, its 1964 installation of the Bailey 760 Boiler Control System and American Shipbuilding AmThrust dual ...
As a result, in 1891 the NNWSS took over the rival Liverpool, Llandudno and Welsh Coast Steam Boat Company (LL&WC) to form the LNWSC. The original St Tudno was sold to Germany , but along with the older and smaller LL&WC steamers was replaced by the brand new St Tudno , which became the first ship to run under LNWSC colours.
Historically, prefixes for civilian vessels often identified the vessel's mode of propulsion, such as "MV" (motor vessel), "SS" (screw steamer; [2] often cited as "steam ship"), or "PS" (paddle steamer). [3] [2] These days, general civilian prefixes are used inconsistently, and frequently not at all.
