This publication looks in detail at the operation, maintenance and troubleshooting of onboard electrical systems and appliances. It provides guidance on how to read a variety of electrical diagrams, power and control circuit construction and components, troubleshooting techniques and regular maintenance. It can be used as a comprehensive source of reference for management and operational level engineers as well as ETOs at any stage of their career.

Written by an industry expert, this publication covers every essential aspect of onboard automated systems. Recognised by The Canadian Ministry of Transportation as one of the publications recommended for ETO education in Canada, this second edition has been fully updated to include advances in marine automation and the wide variety of modern electrical appliances. It describes the features of different onboard circuits and the essential maintenance tasks to help prevent malfunctions and breakdowns. It also demonstrates how to approach troubleshooting in an efficient manner, so that beginners in electrical engineering can quickly gain a level of proficiency and professionals may greatly enhance their troubleshooting skills. The guide is illustrated throughout with circuit diagrams, component schematics and case study photographs taken on board during modern fleet inspections.

This guide will benefit:

Management level marine engineers

operational level marine engineers

ETOs at any level of professionalism

engineering cadets

electrical engineering cadets.

Preface to the Second Edition

Working on board as an ETO or marine engineer requires efficient resolution of various malfunctions, which are often quite unpredictable, as well as essential maintenance tasks to help prevent the occurrence of malfunctions and breakdowns. This demands skills and troubleshooting techniques that cannot be learnt in marine academies and institutions, but are developed through years of experience on board.

Almost a decade has passed since publication of the first edition of Ship Automation. These years were spent on troubleshooting tasks as well as working as a trainer in the field of marine automation. So, it is time to upgrade the first edition with more useful information for all who work with onboard automation.

This edition has been written bearing in mind the rapid changes in marine automation, focusing on demonstrating how to approach troubleshooting in an efficient manner, so that beginners in this field can quickly gain some level of proficiency.

This book will introduce you to a variety of modern electrical appliances that are utilised for ships’ automation and you will progress to reading electrical diagrams like a skilled electrician. If you find yourself reading something you already know, read it anyway; you may gain a better foundation for what follows. Every paragraph is considered important, so do not rush or try to cover a lot of pages in a short period of time. Once you have read each chapter, you should look at your current ship’s diagrams to find out what is common between the explanations and the reality you will encounter.

Although the information provided in this book is based on maritime industry expertise and the author’s many years of experience, it is intended to be used only as a technical guide.

However, you will not become a troubleshooter just by reading this book. Learning through experience will always be the best training.

Personnel who will find this book both educational and informative include:

  • Management level marine engineers
  • operational level marine engineers
  • ETOs at any level of professionalism
  • engineering cadets
  • electrical engineering cadets.

Good luck and fair troubleshooting.
