Paddle Steamers with Turbine Engines

Turbines were fitted to three experimental paddle tugs built for use on the River Rhein in the mid 1920s and one on the River Rhone, but it never caught on and as far as the webmaster knows, was not attempted elsewhere. The above photo and drawing show the turbine and reduction gear fitted to the tug "Dordrecht". Photo courtesy of Felix Brun /Alstom Power (successors to Brown Boveri) archive.

PT Zurich (1922) : Escher Wyss (Zurich)
PT Dordrecht (1925) : Schiffs- und Maschinenbau Gesellschaft (Mannheim) / Brown Boveri Company
PT Toulon (1929) : Sachsenberg / Parsons
PT Rhone (1931) : Escher, Wyss (Zurich)


Dordrecht was built for Dutch owners and with collapsable funnels so as to be able to sail beyond Basel in Switzerland. She was one of the longest Rhine tugs at 77.81 metres and was 22.20 metres in breadth. Steam was fed at 300 degrees celsius from twin Scotch boilers to two turbines, one high-pressure, the other low. There was one reverse turbine. The turbines generated 1500 ships horse power. Double reduction gearing reduced the revolutions from 3600 to 38. Reboilered in 1954 she was withdrawn in 1957, parts of her boiler reused in another vessel and the forward part of her hull used as a clubhouse for the Seafarers-Club at Bonn
