Turbine waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to Swedish engineer Gustaf de Laval (1845–1913) for invention of the impulse turbine. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery. The word "turbine" was coined in 1822 by the French mining engineer Claude Burdin from the
Union Steamship Company of British Columbia Northland Navigation in 1962. The line had a good safety record in an age before satellites and radar. The "Chehalis" sank off Brockton Point in 1913 with a loss of life; the "Cheslakee" capsized on Texada Island; and the "Comox" collided with a ship in fog in Malaspina Strait. It should be remembered that this is over 50 years and a service of dozens of ships.
