CONSIDERATIONS COVERING THE DESIGN OF A LARGE OCEAN-GOING TUG AND ITS DECK MACHINERY
A four engines/twin screw configuration for large ocean-going tugs is preferred, the main reason being increased versatility and economy of operation. Smaller engines simplify operation at sea and also give more flexibility in the choice of auxiliary drives. To reduce noise and the amount of machinery running at any one time, it is preferred to drive the the generators from the main engines running at a constant speed. With one generator on each gearbox, the whole of the ship's electrical requirement can be provided with any of the four main engines running. The turbo-blowers can also be run more efficiently. A recent deck machinery development is the traction winch, which is really a twin drum capstan winch separating the functions of traction and storage. Another piece of equipment furthering for the safety of personnel is the pennant winch, which allows men to work in comparatively safe areas of the after-deck. Order from BSRA as No. 54,304.
