IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus develop-ment process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve with-out compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus devel-opment process, the IEEE does not independently evaluate, test, or verify the accuracy of any of the information contained in its standards.

Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or other dam-age, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document.

The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a specific purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards documents are supplied �AS IS.�

The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the viewpoint expressed at the time a standard is approved and issued is subject to change brought about through developments in the state of the art and comments received from users of the standard. Every IEEE Standard is subjected to review at least every five years for revi-sion or reaffirmation. When a document is more than five years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest edition of any IEEE Standard.

In publishing and making this document available, the IEEE is not suggesting or rendering professional or other services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely upon the advice of a com-petent professional in determining the exercise of reasonable care in any given circumstances.

Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned interests, it is important to ensure that any interpretation has also received the concurrence of a balance of interests. For this reason, IEEE and the members of its soci-eties and Standards Coordinating Committees are not able to provide an instant response to interpretation requests except in those cases where the matter has previously received formal consideration.

Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Comments on standards and requests for interpretations should be addressed to:

Introduction

(This introduction is not part of IEEE Std 45-2002, IEEE Recommended Practice for Electrical Installations on Shipboard.)

IEEE Std 45-2002, IEEE Recommended Practice for Electrical Installations on Shipboard, constitutes the chief undertaking of the Marine Transportation Committee of the IEEE Industry Applications Society.

Due to the differences among the requirements of the various classification societies and the insurance companies regarding electrical installations on shipboard, and the lack of any accepted standard engineering regarding electrical installations on shipboard, and the lack of any accepted standard engineering practice for marine installations, the AIEEa in 1913 appointed the Marine Committee (now called Marine Transportation Committee) to take up the preparation of standard marine rules. The first edition was prepared covering two important divisions; namely, fire protection requirements and marine construction requirements. They were adopted by the American Bureau of Shipping and published as Section 37 of their Rules for the building and classing of vessels. As the first edition of the rules did not cover the entire field of use of electricity on shipboard, the Marine Committee of the Institute was continued. The recommendations were considerably amplified in the editions issued in 1920, 1927, 1930, 1938, 1940, 1945, 1948, 1951, 1955, 1958, 1962, 1967, 1971, 1977, 1983, and 1998.

This edition updates the 1998 edition. The standard has been reorganized to eliminate duplications and make it easier to use. It includes many significant additions, changes, and deletions to reflect North American and International marine electrical engineering technology and the latest system design, installation, and test practices necessary to ensure safe and reliable operation.

aIn 1963 the American Institute of Electrical Engineers (AIEE) merged with the Institute of Radio Engineers (IRE) to become the Institute of Electrical and Electronics Engineers, Inc. (IEEE).

As an IEEE recommended practice, this document provides procedures preferred by IEEE. Following the procedures in this recommended practice does not guarantee safety, and users should take all the reasonable, independent steps necessary to minimize risks to safety.

IEEE Recommended Practice for Electrical Installations on Shipboard

1. Overview

1.1 Scope

These recommendations establish the minimally acceptable guidelines for the design, selection, and installation of systems and equipment aboard marine vessels applying electrical apparatus for power, propulsion, steering, automation, navigation, lighting, and communications. These recommendations describe present-day acceptable electrical engineering methods and practices.

It is recognized that changes and improvements in shipboard requirements may develop that are not specifically covered herein; such changes, if incorporated in the design, should be equal to the safety and reliability levels established herein and generally in accord with the intent of these standards.

In developing these recommendations, consideration was given to the electrical and engineering requirements promulgated by various regulatory agencies, classification societies, and by the International Maritime Organization�s International Convention for the Safety of Life at Sea (IMO SOLAS), as amended.

This recommended practice was developed by a voluntary consensus body to provide assistance and guidance to regulatory agencies governing electrical engineering requirements.

1.2 Purpose

The main purpose of this recommended practice is to provide a consensus of recommended practices in the unique field of marine electrical engineering as applied specifically to ships, shipboard systems, and equipment.

1.3 Vessel classification

1.3.1 Vessel classification this recommended practice is applicable to

These recommendations have been prepared for application for the following vessels:

a) Tank vessels�All vessels whose principle purpose is the carrying of combustible or flammable liquid cargo in bulk.

1.5 Environmental conditions

1.5.1 Normal design and operating conditions

Systems and equipment should be suitable for continuous operation under the following shipboard conditions:

a) Exposure to moisture-laden and salt-laden atmosphere, weather, sun, high wind velocities, and ice.

b) Equipment and systems shall be designed for temperature extremes and conditions expected.

Typically, the following conditions can be used: ambient temperature values of 40 °C in accommodation areas, and similar spaces; 45 °C in main and auxiliary machinery spaces; 50 °C for rotating machinery and propulsion equipment in main and auxiliary machinery spaces containing significant heat sources such as prime movers and boilers; and 65 °C in the uptakes of machinery spaces containing prime movers and boilers; all at relative humidities up to 95%. The design value for seawater cooling temperature should be 32 °C.

c) Roll and pitch of a vessel underway, as shown in Table 1.

d) Vibration of a vessel underway: Electrical equipment should be constructed to withstand at least the following:

1) Vibration frequency range of 5�50 Hz with a velocity amplitude of 20 mm/s.

2) Peak accelerations due to ship motion in a seaway of ± 5.9 m/sec2 for ships exceeding 90 m in length, and ± 9.8 m/sec2 for smaller ships, with a duration of 5�10 s.

1.5.2 Abnormal design and operating conditions

Special conditions for a specific ship design or operating arrangement may require special consideration.

Examples of such conditions include, but are not necessarily limited to

� Exposure to damaging fumes or vapors, excessive or abrasive dust, steam, salt-spray, ice, sunlight, physical damage, and so on

� Exposure to high levels of shock and vibration � Exposure to high or low temperatures � Operation in flammable atmospheres (see Clause 33) � Exposure to unusual loading or unloading conditions affecting list and trim � Unusual operating cycles, frequency of operation, poor power quality, special insulation requirements, stringent or difficult maintenance requirements, and so on

1.6 Equipment construction, testing, and certification

Electrical apparatus and equipment should be constructed and tested in accordance with the requirements of appropriate national and international equipment standards. Standards specifically addressing marine requirements should be used whenever applicable. Many appropriate standards are referenced in this document. All electrical equipment should be tested and certified, with labeling and follow-up services (i.e., listed) by a recognized independent laboratory acceptable to the authority having jurisdiction.

1.7 Application of various national and international standards

Special precautions must be exercised when mixing equipment designed to different national and interna-tional standards. Coordination of different equipment design and testing standards, construction ratings, installation methods, and performance must be carefully analyzed.

1.8 Materials

1.8.1 Corrosion-resistant parts

Where essential to minimize deterioration due to marine atmospheric corrosion, corrosion-resisting materials, or other materials treated in a satisfactory manner to render them adequately resistant to corrosion, should be used. Silver, corrosion-resisting steel, copper, brass, bronze, copper-nickel, certain nickel-copper alloys, and certain aluminum alloys are considered satisfactory corrosion-resisting materials.

The following treatments, when properly performed and of a sufficiently heavy coating, are considered satisfactory corrosion-resistant treatments:

� Electroplating

� Sherardizing

� Galvanizing

� Dipping and painting (phosphate or suitable cleaning, followed by the application of a coating system) meeting the requirements of ASTM B117-971).

These provisions apply to the following components:

� Parts. Interior small parts that are normally expected to be removed in service, such as bolts, nuts, pins, screws, cap screws, terminals, brushholder studs, springs, and so on.

� Assemblies, subassemblies, and other units where necessary due to the unit function, or for interior protection, such as shafts within a motor or generator enclosure, and surface of stator and rotor.

1Information on references can be found in Clause 2.

CAUTION

It is recognized that various national and international standards for equipment and installations are not identical. However, it is recognized that mixing of standards is occasionally necessary. Therefore, the application of any of these standards is the choice of the user, authority having jurisdiction, and classification society.

� Enclosures and their fastenings and fittings. Enclosing cases for control apparatus, outer cases for signal and communication systems (both outside and inside), and similar items, together with all their fastenings and fittings that would be seriously damaged or rendered ineffective by corrosion.

1.8.2 Flame-retardant materials

Flame-retardant materials and structures should be used to the maximum extent practicable throughout the vessel. These materials should have such fire-resisting properties that they will not convey flame nor continue to burn for longer times than specified in the appropriate flame test.

Compliance with the requirements of the preceding paragraph should be determined with the apparatus and according to the methods described in appropriate nationally recognized test laboratory standards for the materials and structures being considered, unless specific applicable tests are invoked in these recommendations.

1.9 Brittle material

Porcelain or other brittle insulating materials should not be used for bus supports, lamp sockets, receptacles, fuse blocks, and so on, where the material is rigidly fastened by machine screws or equivalent.
