Overview
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.

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. Certain aspects are covered in greater detail in other parts of the Marine Engineering Practice series and reference has been made to the relevant titles where appropriate.
While this book is intended to give guidance, reference must also be made to the equipment manufacturer’s operation and maintenance manuals. The chapter on electrical machinery sets out guidelines on electrical maintenance and is of particular importance on ships that do not carry electricians.
Changes to shipboard practice have been required to ensure compliance with the MARPOL Convention concerning pollution prevention and environmental protection. Crew must be aware of the regulations concerning the disposal of wastes, including bilge water, sludge, sewage, garbage and emissions, and these are discussed in Chapter 6.
