DIESEL-ELECTRIC PROPULSION FOR FLEXIBILITY AND ECONOMY

The Author, of Cable & Wireless, describes the Diesel-electric propulsion arrangements to be installed in a new cable-repair ship that his company ordered from Swan Hunter at the end of 1982, and discusses some advantages of this type of propulsion for such vessels The ship has been designed to handle all types of submarine cable; she will be stationed in a remote area of the Pacific, and maintenance under these conditions was a factor in the design of the machinery installation. Her length o.a. is 115 m and breadth 18 m; classification will be to LR 1OO A1, UMS, Ice Class 3. The ship will have a single f.p. propeller driven by two d.c. variable speed reversible motors, rated at 2200 kW, mounted in-line and directly coupled to the propeller shaft. There are also two thrusters, one forward and one aft, each with a 360-deg. rotatable vane directing a water jet; they are powered by two 750-kW variable-speed d.c. motors. All these motors are supplied through thyristor converters. Two 2000-kW Diesel-generator sets supply all power requirements and are used in different combinations to suit the load; the switchboard, transformer and associated arrangements are briefly decribed. An integrated control system allows the propeller, thrusters and rudder to be controlled from a single joystick on the bridge, bows or stern.
