Accession No.628


The Viper (length 210 feet, beam 21 feet; displacement 350 tons) was fitted with four 11,000 indicated horsepower (total) two-cylinder turbines that were similar to those of the Turbina; these were in two independent sets, one for each side of the vessel. The high-pressure turbines were directly coupled to the wing shafts, and the low-pressure turbines to the centre shafts. Small reversing turbines were also permanently coupled to these shafts; these revolved idly when the vessel was going ahead. The reversing turbines provided sufficient power to drive the vessel astern at a speed of 15 knots. The builders of the Viper were the Parsons Marine Steam Turbine Company, Limited, of Newcastle-on-Tyne.
