Ships having in general one or more of the following characteristics: A very large cubic capacity and a relatively small draught. High speed and problems in propeller design because of small draught and high speed. Very often gear for horizontal handling: truck to truck or roll on roll off. For such ships medium speed diesels offer the following advantages: Low height particularly advantageous on roll on roll off ships. The absence of a large engine casing. This gives an effective gain in available space. Easing of the stability problem so compensating for the deck load (containers). The possibility of using coupled alternators. The authors give several examples: Orthodox refrigerated cargo ships; polytherm and multipurpose cargo ships; Ro-Lo container ship. Medium speed diesels do however present certain inconveniences: High consumption of lubricating oil. High level of noise and vibration. Power is limited by the practicable number of cylinders.
