IEEE 45.4-2018 pdf free.IEEE Recommended Practice for Electrical Installations on Shipboard-Marine Sectors and Mission Systems.
The IEEE 45 series of recommended practices have been prepared for application a broad range of both commercial and naval vessels, as outlined in Figure 2. including:
a) Passenger vessels:
I) All vessels of 100 gross tons or more whose principle purpose is the carrying ot passengerS.
2) Passenger vessels under 1(X) gross tons carrying more than six but less than 150 passengers or that has overnight accommodations for less than 50 passengers.
3) Passenger vessels carrying more than 150 passengers or with overnight accommodations for more than 49 passengers.
b) Cargo vessels:
1) Liquid: All vessels whose principle purpose is the carrying of combustible, flammable, or ha,ardous liquid cargo in bulk (e.g., crude oil, refined oil, gasoline, liquid chemicals, etc.).
2) Dry: All vessels carrying freight for hire (e.g.. bulk. containerized, automobiles, etc.)
c) Work vessels:
I) Offshore supply vessels.
2) Nautical school vessels,
3) Oceanographic research vessels—All vessels engaged in oceanographic research.
4) Mobile offshore drilling units (MODU)—A vessel, other than a “mobile inland drilling unit,” which is capable of engaging in drilling or workover operations for the explorations and exploitation of subsea mineral resources. These recommendations apply to all types of MODUs without production facilities, including, but not limited to. semi-submersible units, submersible units, self-elevating or jack-up units, and drill ships and tenders.
5) Mobile inland drilling units (MIDU)—A vessel, other than a “mobile offshore drilling unit,” which is capable ofengaging in drilling or workovcr operations for the exploration or exploitation of subsea mineral resources and is designed and intended for use in US waters, rivers, inland lakes, hays, or sounds. These recomiiiendations apply to all types of Mll)U without production facilities. including, but not limited to, inland barges and posted inland barges.
d) Miscellaneous vessels—All vessels not covered in other groups, all tugboats and tow boats, and all seagoing barges not covered in other groups.
c) Naval vessels:
1) Noncombatant vessels—Including all naval auxiliary ships, military supply vessels, and icebreakers.
2) Combatant vessels.
Vessel classification and facilities the IEEE 45 series recommended practices are not applicable to:
a) Fixed petroleum facilities.
b) Floating petroleum facilities- A buoyant facility that is securely and substantially moored so that it cannot be moved without a special effort. The term includes, but is not limited to, tension leg platforms. floating production systems. floating production storage and ofiloading (FPSO). and spar buoy or deep drati caisson vessel. These types of floating facilities are site-specific and not intended for periodic relocation. Other types of floating facilities include permanently moored semi-submersibles and shipshape hulls. All of these types of floating facilities produce hydrocarbons from the well and process them on board and either store them on board and pump the produced hydrocarbon into a pipeline or directly onto another vessel.
c) Recreational vessels.
NOTE—These recommendations have not been prepared for application for the facilities and vessels listed in item a) item b), and item c) because they are outsidc thc scope of this recommended practice and are covered under national and international standards.4
3.4 Vessel classification electric load distinctions
For the purposes of this recommended practice. a major difference between vessel classifications within the commercial sub-class is the type of electrical load supplied by the electrical plant. A non-exhaustive list is given below.
a) COMMERciAL—Passenger: Primary load is propulsion (for hulls with electric propulsion). Sizeable loads include pumps and low-voltage lighting and heating/cooling.
b) COMMERCIAL—Caigo: Primary load is propulsion (for hulls with electric propulsion). Sizeable loads include material handling and pumps. Material handling may be physically located above or below main deck level.
c) COMMERCIAL—Wirk. Primary load is propulsion (for hulls with electric propulsion). Sizeable loads include process equipment — which varies by vessel purpose — and pumps. Special notice should be taken for vessels involved in oceanographic or atmospheric observation, where an abundance of clcan” power is required for the scientific equipment.IEEE 45.4 pdf download.
