IEEE Std 45.4:2018 pdf download.IEEE Recommended Practice for Electrical Installations on Shipboard-Marine Sectors and Mission Systems.
This recommended practice identifies the various marine segments and ships covered in the IEEE 45TM 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.
1.2 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.
2. Normative references
The following referenced documents are indispensable for the application of this document (i.e., they must be understood and used, so each referenced document is cited in text and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments or corrigenda) applies.
IEEE Std 45.1 TM-2017, IEEE Recommended Practice for Electrical Installations on Shipboard—Design.
IEEE Std 45.3-2O15, IEEE Recommended Practice for Shipboard Electrical Installations—Systems Engineering.
3. Marine sectors and mission systems
3.1 Background
Figure 1 shows the design process from concept design to product baseline and the relationship between IEEE Std 45.1-2017 and IEEE Std 45.3-2015, which provide the recommended practice for electrical installations shipboard.3 This standard provides the definition of which ship types the IEEE 45 series of recommended practices are applicable to.
3.2 Ship types
There are innumerable schemes developed to classify ships and vessels. Figure 2 provides a simplified taxonomy of ship and vessel types, broadly divided between commercial and naval vessels. There may be commonality between vessel types, and often a vessel can be suitable for multiple roles. For instance, commercial ocean liners have often been re-designated naval troop carriers in time of conflict. In addition to the taxonomy of subdividing ships and vessels by function, there are also classifications by governing authority which include (not an exhaustive list):
— Sovereign government: Military specifications and standards for naval vessels
— American Bureau of Shipping (ABS)
— Germanischer Lloyd (GL)
— Bureau Veritas
— Det Norske Veritas
— Lloyd’s Register
— Russian Maritime Register of Shipping
— Nippon Kaiji Kyokai
— Korean Register of Shipping
— Indian Register of Shipping
— Polish Register of Shipping
— Registro Italiano Navale
— Croatian Register of Shipping
— China Classification Society
The vessel owner, based on the vessel’s purpose, will determine which classification standards to require. The vessel designer and vessel builder must design and build the vessel to those standards.IEEE Std 45.4 pdf download.
