The book sets out the fundamental principles of marine engineering and then discusses propulsion and electric power, energy conversion, power plant concepts, main machinery, diesel engines, gas turbines, electrical components, propellers, matching propulsion engine to propeller, and ship fuel consumption and exhaust emission.


Written by Hans Klein Woud and Douwe Stapersma, the book is based on some 30 years of practical experience with the design of machinery systems, mainly for naval ships. Both authors have worked on the design of propulsion, electric power generation and auxiliary systems for frigates, submarines and patrol ships. They have lectured on marine engineering at the Delft University of Technology and at the Royal Netherlands Naval College.
