Book Description

The second edition of Shipboard Electrical Power Systems addresses new developments in this rapidly growing field. Focusing on the industry trend toward electric propulsion for cruise, navy, and commercial ships, the book aids new or experienced engineers in mastering the cutting-edge technologies required for power system design, control, protection, and economic use of power.

Covering the latest emission standards on ships, and the clean power technologies necessary to meet such stringent regulations, the book compiles essential information on power system design, analysis and operation, uniquely bringing all three together under one cover. Beginning by covering power system basics, the book goes on to detail power generation, electrical machines and batteries, with brand new chapters on electric propulsion, shipboard emission regulations, and clean power technologies. Updated throughout to reflect this rapidly changing field, the second edition clearly explains complicated electrical concepts using mechanical and hydraulic analogies to aid marine engineers in understanding difficult elements of the field. The book is an indispensable resource for well-rounded engineering students and professional engineers.

This textbook is essential reading for students of marine engineering, electrical power systems, and electrical engineering, alongside engineers working on commercial and navy ships, on ports, on land, and offshore rigs.
