Within the marine and offshore industry, there is a clear and growing need for increased training and education on the use of electrical power systems. The number of electrical plant and appliances now in service has grown at an alarming rate in recent years, as has the amount of electrical power generated and utilised on board.

Large passenger ships now carry as many electrical officers as marine engineers, and electrical propulsion is now in common use by LNG carriers, small parcel tankers, oil tankers, ferries, offshore support, the navy, fleet auxiliary, cable layers and cruise ships. A number of shipping companies now award the Chief Electro Technical Officer the equivalent rank to the ships master and Chief Engineer. These developments have resulted in the establishment of a Foundation Degree programme for Electro Technical Officers and the current development of full degree programmes. As such, a targeted textbook for students on the subject is required.

As with all titles in the Reeds Marine Engineering Series, this book will be written in clear, accessible language, so as to be of use to all students and particularly those for whom English isnt their first language. Technical drawings and diagrams will be used throughout and each chapter will be accompanied by example examination questions.

Papildus informācija

A new title in the highly respected Reeds Marine Engineering Series, in response to the increasing reliance on electrical power systems in the marine and offshore industry.

Gordon Boyd is a Chartered Electrical Engineer and Senior Lecturer at South Tyneside College, the largest Marine Engineering College in the UK and well recognised internationally as being a world leader in electrical aspects of Marine Engineering education and training. He is also a Consultant for Electric Works developing distance-learning packages and computer-based learning training for Marine Engineers and ETOs, and has extensive sea-going experience. He is author of Reeds Vol 10: Instrumentation and Control Systems for Marine Engineers.

As a school leaver Fred Taylor was trained in marine engineering by Shell. On completion of his cadet programme he joined NEI Parsons as a student apprentice electrical engineer. During this period, he studied a degree programme and gained a B Eng. (Hons) in Electrical Engineering at Newcastle Polytechnic in 1971. In the following year he joined South Shields Marine and Technical College as a member of the lecturing staff. He is currently engaged as a consultant to South Tyneside Marine College in South Shields and other industrial clients.
