An excellent guide to the electrical technology on board ships released by the MarineInsight team. Any vessel is like a floating city enjoying nearly all privileges that are commonly available to any of those operational set-ups ashore. Like any city, the vessel requires some fundamental amenities in order to sustain life on boars, and the most important of the amenities would be electrical power, which is generated by shipboard generator or alternator working together.

The material in this booklet is arranged in four sections. The first section provides the general information on power generation, shipboard HV systems and electrical propulsion of vessels. The second section of the book is devoted to the electrical instruments including PMMC and Megger, thermocouples, rectifiers and amplifiers together with the associated circuits.

The next section addresses electrical safety on board ship, covering safety devices fitted on the main switchboard, electrical fires and insulation, safety and precautions, generator safety matters and blackouts. The closing section of the volume is dealing with the electrical maintenance including electrical faults, relay maintenance, motor overhaul, maintenance of bus bars and alternators, and routine inspection of electrical starter panel.

The lectures contained in the book are quite general, and deal with the most important problems of electrical engineering including generation of electrical energy and its control, transmission of energy, its distribution and utilization. It means that the readers will find all required information about the related to the electrical systems and their components, operation of such systems and apparatus under all different conditions covering design of the electrical systems as well.

Note, however, that the design of the electrical apparatus has been discussed only to the extent necessary to get proper understanding of their operation and make further judgment on their application. The treatment of the subject in this book is mainly descriptive not mathematical; it contains the discussion of various applications of the electricity, apparatus and means, and methods of application together with the advantages and disadvantages of different methods determining the choice of particular method and apparatus...

The subject of the present textbook is control of marine vessels. By marine vessels we hereby mean conventional ships, HSC, submarines, semi-submersible offshore structures, floating offshore drilling rigs and other offshore installations, underwater vehicles being remotely or even autonomously operated and any other powered/propelled vehicles.

We all know that a marine vessel during maneuvering experiences motion in six degrees of freedom. The feedback control systems and their application to the ships are becoming more and more popular due to the recent developments kin computer science, ship propulsion systems and sensor technology.

There are many systems commercially available today, such as the auto-pilots for ships and UV used for coursekeeping/turning control, way-point tracking systems, torpedo control systems, depth auto-pilots and attitude control systems used on the underwater vehicles, dynamic positioning (DP) and positioning mooring (PM)  systems on marine vessels and floating structures, path control/trajectory control systems, buoyancy, propulsion, power management and energy control systems, heel/trim correction systems, wave-induced vibration damping systems used on HSC, roll stabilization systems and others...

The book starts with the very fundamentals of the electricity - subject chapter explains the structure of matter and concept of charge, current and electromotive force, charge-current relation, electric resistance, conductivity and resistivity, how temperature affects resistance, insulation resistance, batteries and cells, cell types and terminology involved.

The second chapter deals with the direct current circuits - terminology, their classification, sources of energy, voltage and current division, combination of sources, fundamental laws, source transformation, basic rules, theorems, and concepts. The next chapter addresses magnetic circuits - magnets and their properties, magnetic field, fundamental laws, pole strength, magnetic flux, permeability, reluctance, comparison of electric and magnetic circuits, etc.

Then there comes a chapter dedicated to the electromagnetic induction - the readers will know about Faraday's experiment and his laws of induction, nature of the induced EMF, dynamically-, statically-, self-induced and mutually induced electromagnetic force, energy that is being stored in the magnetic field, etc.

The contents of the book is huge so we will just say in short that the other chapters cover electrostatics, alternate current fundamentals, single-phase and poly-phase A/C circuits, single-phase transformers and so much more useful info.

The capabilities of the PLCs have significantly grown from the time when the first edition of this book was released. Same applies to the applications of the programmable logic controllers. Nowadays, it would be next to impossible to find the industry where the PLC would not be utilized in one form or another. This edition of the publication provides a good practical and theoretical look at nearly all important aspects of programmable controllers, their devices and associated systems.

There are some new chapters included in this edition, e.g. ones touching the input/output bus networks, process control, fuzzy logic etc. this release presents the thoroughly revised and updated information on the existing topics and such info is supplemented with graphics and hands-on examples for better understanding and illustration. The new layout has been implemented by the authors.

In addition, there is a Glossary at the end of the book explaining the terminology and abbreviations used throughout this publication and in the electrical engineering, in general.
