Description: Marine Electrical Practice has been regarded as the standard work on the installation, maintenance and operation of marine electrical equipment since it was first published in 1957. Many changes have of course taken place since that time which have been reflected in the various new editions of this work. The greatest change which has taken place since publication of the fifth edition is the increasingly widespread use of programmable electronic systems (PESs). These range from small programmable controllers for small discrete systems through to multiple microprocessor systems for machinery monitoring, alarm and control. As well as a new chapter on PESs, this sixth edition includes an additional chapter on protection and discnmination, a new section on impressed current cathodic protection and its updated throughout to take account of recent technological advances.
This book was designed by the late G. O. Watson, with whom it will always be associated to meet the needs of engineers studying for certificates of competency and seagoing engineers and electricians. Members of BP Shipping Limited, of Harlow. Essex, have revised the book tor the sixth edition so that it will continue to meet those needs for many years to come.

Marine Engineering now includes the field of offshore engineering as well as traditional seagoing ships. It is generally accepted by those with experience in this industry that electrical apparatus manufactured primarily for land use is not. as a result, suitable for installation in a marine environment Climatic conditions, vibration, the continual motion of a ship, temperature and conditions of usage are all contributory factors. Usually (although admittedly not in every case) apparatus ashore is not operated at a constant load, day and night, for long periods; in industry there are peak loads and off-peak load periods and these factors have considerable effect on the life of equipment. Factories may be remodelled as nc\s production lines are introduced or new machine tools become available, but in the marine industry the electrical equipment is expected to last the lifetime of the installation. During this time maximum reliability is important, particular!) in regard to those services which are vital for propulsion and safety.
