RMS Victorian was an ocean liner of the Allan Line, built for service between Britain and North America. The liner was launched in 1904 and was the first large civilian ship propelled by steam turbines. Victorian was in service for almost a quarter of a century, and was broken up in 1929.
Canadian Pacific Steamship Company bought the Beaver Line in 1903 and entered the transatlantic trade. To compete, the Allan Line ordered two large new liners in October 1903. They were originally intended to be conventional twin-screw ships powered by reciprocating steam engines.
The specification was changed to three-shafted vessels propelled by steam turbines in light of the great success of King Edward, a turbine-powered excursion vessel in service on the Firth of Clyde since 1901. Allan Line ordered engines similar to that of King Edward and from the same builder, the Parsons Marine Steam Turbine Company. Victorian became the first three-shaft ship and the first turbine liner in Atlantic service, and with sister ship RMS Virginian became the first large turbine-powered commercial vessels of any kind, at a time when others doubted the wisdom of using the new technology in large ships.
The engines in Victorian were a scaled-up version of that in King Edward. Coal-fired Scotch marine boilers supplied steam at 180 psi (12.66 bar) to Parsons turbines. The smoke was exhausted through a large single stack. The high-pressure steam from the boilers was fed to a turbine directly driving the centre shaft; from the centre turbine steam was reused at a lower pressure in flanking turbines, each directly turning a wing shaft. Each shaft had a single screw.
