45_WG - Working Group for Electrical Installations on Shipboards

Dwight Alexander

This recommended practice identifies the various marine segments and ships covered by IEEE 45 and other standards such as IEEE 1713. It provides grouping of ships and their predominant mission systems for classification and used by other parts of IEEE 45 and other standards. This document is intended to be used in conjunction with IEEE 45.

A consensus of recommended practices for system testing in marine electrical engineering as applied specifically to vessels, shipboard systems, and equipment is provided.

Recommendations for the design of electrical power generation, distribution, propulsion, loads systems, and equipment on merchant, commercial, and naval vessels are covered in this document.

This recommended practice covers electrical safety considerations for shipboard electrical systems and equipment including a review of fundamental concepts pertaining to electrical safety and establishing electrical safety programs and work practices associated with the operation and maintenance of shipboard electrical power distribution systems.

Recommendations are provided for selection, application, and installation of electrical power, signal, control, data, and specialty marine cable systems on shipboard.

Recommendations for the design, selection, and installation of switchboards on merchant vessels with electrical apparatus for lighting, signaling, communication, power, and propulsion are provided.

Recommendations for systems engineering, design, and integration of electrical power systems at the total ship level from concept design through the establishment of the design baseline prior to detail design are provided in this document. Recommendations for ac power systems, dc power systems, emergency power systems, shore power, quality of service, power quality and harmonics, electric propulsion and maneuvering systems, motors and drives, thrusters, and steering systems onboard ships are established by this document. These recommendations reflect the present-day technologies, engineering methods, and engineering practices. This document is intended to be used in conjunction with the IEEE 45(TM) series of documents.

These marine recommendations are intended to serve as a guide for the selection and installation of equipment on merchant vessels with electric apparatus for lighting, signaling, communication, power, and propulsion. The recommendations define what are considered good present-day engineering practices with reference to the safety of the personnel and of the ship itself as well as reliability and durability of the apparatus. It is recognized that changes and improvements in shipboard requirements may develop which are not specifically covered herein; such changes, if incorporated in the design, should be equal to the safety and reliability levels defined herein and generally in accord with the text of these standards. Specific IEEE standards are referenced in the text. Other IEEE standards should be followed to the extent applicable. Attention is directed to the fact that regulations for electric installations on shipboard are promulgated by Governmental Regulatory Agencies, the Intergovernmental Maritime Consultative Organization, and Classification Societies. Such regulations have been given due consideration in these recommendations, but there are areas where differences are expressed. Reference should always be made to those regulations which may be applicable to the design.
