Page 8 - Introduction to Naval Architecture
P. 8
Preface to the third edition
One definition of wisdom is the thoughtful application of learning;
insight; good sense; judgement. It can be said that this book aims to
contribute to the reader's wisdom. It sets out to provide knowledge of
the fundamentals of naval architecture so that the reader can define a
ship form, calculate its draughts and displacement and check its
stability. It seeks to give an understanding of other aspects of the ship
such as the possible modes of structural failure and its manoeuvring
and seakeeping performance. It presents information on the environ-
ment in which the ship has to operate, and describes the signs that
might indicate pending trouble.
As with all branches of engineering, naval architecture is changing
dramatically as a result of modern technology. Computers have made a
big impact on the design, construction and operation of ships. New
materials and changing world economics are bringing new ship types
into commercial use or resulting in changes in more established types.
Greater emphasis on protection of the environment has led to new
regulations on waste disposal and the design of ships to minimize the
harmful results of oil spillages and other accidents. There is now
greater attention to safety of life at sea, not least as a result of the tragic
loss of life in passenger ferries such as the Estonia and the Herald of Free
Enterprise.
Because of the rate of change in the subject, new texts are required
not only by those beginning a career in the profession but also by those
already involved who wish to keep their knowledge up-dated. This book
is intended only as an introduction to naval architecture. It sets out to
educate those who need some knowledge of the subject in their work,
such as sea-going engineers and those who work in design offices and
production organizations associated with the maritime sector. It will
help those who aspire to acquire a qualification in naval architecture up
to about the incorporated engineer level. Most major design calcula-
tions are, today, carried out by computer. However, it is vital that the
underlying principles are understood if computer programs are to be
applied intelligently. It is this understanding which this book sets out to
provide for the technician.
