Parsons Marine Steam Turbine Company Parsons Marine Steam Turbine Company Parsons Marine Steam Turbine Company was a British engineering company based in Wallsend, North East England, on the River Tyne. The company was founded by Charles Algernon Parsons in 1897 with £500,000 of capital, and specialised in building the steam turbine engines that he had invented for naval use. The first ship to use a Parsons propulsion system was "Turbinia", launched in 1894; the successful demonstration of this vessel led to the creation of the company and the subsequent construction of the engines for the first two turbine-powered destroyers for the Navy, and , launched
Rim-driven thruster Rim-driven thruster Rim-Driven Thruster is a novel type of propulsion unit which was presented at the Shipbuilding, Machinery & Marine Technology 2010 trade fair (SMM) by the companies "Voith" and "Van der Velden". The Rim-driven thruster is a marine propeller which does not need a hub for transmission of the driving torque. Conventional propellers need a shaft line which is driven by a turbine, a diesel engine or an electric motor. The more recent podded drives consist of a conventional propeller which is arranged together with a conventional electric motor into an azimuthable gondola under water. The blades of the
