MEDIUM SPEED ENGINES IN SHIPS

Geared multiple engine plant came into use in ships some years ago, admittedly only in smaller vessels with relatively low propulsive output to begin with. With the development of all makes of larger engines with higher output, able to run on heavy fuel oil without difficulty, such plant has been introduced increasingly into larger and faster vessels of almost every type. Some examples of installations for such plant are given and the essential advantages of marine medium speed engine plant over alternative forms of propulsion outlined. The design features of two medium speed engines developing 560 and 1000 bhp (metric) per cylinder are described and their operating data specified. As special attention must be paid to the questions relating to maintenance and overhaul in plant comprising a relatively large number of cylinders, all the measures taken in these engines to facilitate such work are treated in detail. The damping of noise produced by such engines is also discussed. Details are given of the service life and periods between overhauls for the essential parts subject to wear and, in conclusion, comments are made upon the question of the reliability of these engines.
