IEEE 45.4:2019

Scope
This recommended practice identifies the various marine segments and ships covered in the IEEE 45(TM) series of standards. It provides grouping of ships and their predominant mission systems for classification and used by other parts of IEEE 45. This document is intended to be used in conjunction with other IEEE 45 standards.
Purpose
An extension of the baseline technology and methods covered by IEEE 45, this standard provides a consensus of recommended practices for marine sectors and mission systems in marine electrical engineering as applied specifically to ships, shipboard systems, and equipment.
Abstract
New IEEE Standard - Active. Recommendations for the grouping of ships and their predominant mission systems to define and highlight unique features and requirements of a shipa??s electrical power system driven by the shipa??s mission for classification and use by the IEEE 45(TM) series of standards
