The publication presents a professional feasibility study of the proposed technical solutions for the on-shore electrical infrastructure to supply ships with the electrical power during their staying at ports. The vessels utilize their diesel engines in order to produce the electricity they require for the loading/discharging activities, hoteling and other needs while in ports.
Main shipboard engines are commonly switched off straight after the vessel gets berthed. Nowadays, the auxiliary engines installed on board run on the cheap low quality fuel, and their operation results in the negative impact on the environment. There are several marine ports applying the shore-side electrical power supply in the port infrastructure and the environment of those parts have significantly improved during past years.
The other ports have subsequently started investigation in this field analyzing the possibilities of arranging the shore-side supply. When preparing a technical design, the first thing to be investigated is the shipboard electrical system. The study contained in this report has shows how the electrical power needs vary depending on the type of ship, ranging from one to eleven megawatts. The ports shall be duly aware of the ship power needs, system voltage and frequency in order to properly design the supply facility...

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.

This publication was written by Tingting Yang and Sherman Shen who made an attempt to cover the constantly emerging networks of maritime wideband communications. The authors are trying to describe to the readers how such networks facilitate the applications like general communications, urgency, maritime distress etc. This book was initially intended to provide a good insight to the scheduling of the maritime data transmission and to the protocol design for the network that has been mentioned above.
The book starts with some brief intro to the networks including their principal architecture, framework and operation principles, and it also includes a survey on current developments in this area. The next part of the book will present the resource allocation as well as the scheduling for the video transmission with the aim to maximize the weights of the video packets being uploaded and transferred. The duet of authors are also proposing an energy and content-aware scheduling scheme for better packet throughput.
Basing on the real vessel route traces received from the navigation programs, the results of the simulations are demonstrating the true viability of the schemes proposed. In addition, the conclusions and valuable suggestions for the future researches have been discussed in this book...
