Description: Over the past six years, since the first edition, there have been developments and advances in the way ship power estimates are carried out, including improvements in experimental,analytical and computational fluid dynamics (CFD) techniques. There has been a significant increase in emphasis on improving energy efficiency and reducing emissions from ships and, in order to promote energy-efficient ship design and the control of CO2 emissions, the International Maritime Organisation (IMO) has introduced an Energy Efficiency Design Index (EEDI). This has led to a closer examination of methods of reducing power, including savings in hull resistance and propeller efficiency and developments in auxiliary propulsion and energy-saving devices (ESDs). A new chapter (Ch. 17) has been introduced to describe the background to the EEDI and to summarise the various ways of reducing propulsive power and emissions.
Numerical resistance estimates and numerical propeller design have been brought up to date,describing recent developments and references.
Typographical errors in the first edition have been removed. There are some gaps in the first edition and the opportunity of a second edition has allowed the inclusion of other topical areas including outline descriptions of pump jets, rim-driven propulsors, shape-adaptive foils, propeller noise and dynamic positioning. Discussion of the relationship between hull form and seakeeping has been expanded. Information on the new controllable pitch Wageningen C and D series has been added. Trials procedures have been updated following the requirements of the IMO for the EEDI. Due to the increase in the development and applications of underwater vehicles, preliminary estimates of power for submarines and autonomous underwater vehicles (AUVs) have been incorporated. Similarly, preliminary power estimates for hydrofoil craft have been included.
The fundamental concepts of ship powering remain unaltered,and the practical approach to powering in the book,together with worked examples, is maintained. The authors wish to acknowledge the work of postgraduate students who have contributed to the Southampton research programme, including Dr. Charles Badoe, Dr. Artur Lidtke, Dr.Thomas Lloyd and Dr. Björn Windén.
