Steam turbine as the main ship propulsion. More than a hundred years at sea

This paper is the first part of a series of articles, encompassing a short historical outline of the development of turbine ship propulsion. In this paper steam turbines are discussed, and the characteristic features of marine steam turbines are described, together with examples of marine power plants. The second part, "Gas turbine: advanced marine propulsion", concerns marine gas turbine units, and presents scientific achievements and state-of-the-art solutions in this field. Finally, the third article, "Marine turbines: cogeneration and combined propulsion systems", is devoted to gas-steam turbine combined propulsion units, the cooperation of turbines with piston engines and integrated energy and heat production in marine power plants. The discussed topic are illustrated with schemes, diagrams of specific technical solutions, and photos. The entire series of articles constitutes a collected source of information on the topic of marine steam and gas turbines.
