Many changes have taken place within the marine industry due to the rapid advances in technology, particularly in engine design and shipboard practice. Medium speed engines have become larger and are installed as main propulsion engines in larger ships, particularly passenger ships. These engines are highly rated and can burn high viscosity residual fuels. Slow speed crosshead engines have also changed and tend to be long stroke, uniflow scavenged with a central exhaust valve. While medium speed builders have added larger engines to their range, slow speed manufacturers have produced smaller bore models. Engine builders have also merged to provide a wider range of engines while remaining competitive.
This publication provides general guidance for the operation and maintenance of machinery in motorships.
