Medium-speed engines now offer a viable alternative to the slow- speed, two-stroke engines for medium size vessels. This was not always so. Medium speed engines suffered during the early days of heavy fuel operation, which translated into higher maintenance costs. Today, however, with a new generation of medium speed engines, the situation is quite different. Where once operators shied away from medium speed engines, they are returning to these engines in certain applications because of the reliability, flexibility, ease of maintenance, and low operational costs that are offered. The use of medium speed propulsion engines is showing an upward trend. To understand this change, the basic design philosophy and features of modern medium-speed engines are discussed.
