3.3 Applicability
3.3.1 Applicable vessels
The IEEE 45 series of recommended practices have been prepared for application a broad range of both commercial and naval vessels, as outlined in 1 igurc D, inchtding:
a) Passenger vessels:
I All vessels of 100 gross tons or more whose principle purpose is the carrying of passengers.
2) Passenger vessels under 100 gross tons carrying more than six but less than 150 passengers or ihu has overnight accommodations for less than 50 passengers.
3) Passenger vesseLs carrying more than ISO passengers or with overnight accommodations for more than 49 passengers.
b) Cargo vessels:
I) Liquid: All vessels whose principle purpose is the carrying of combustible, flammable, or hazanlous liquid cargo in hulk (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:
1) Offshore supply vessels.
2) Nautical school vcssels,
3) Oceanographic research vessels—All vessels engaged in oceanographic research.
4) Mobile ofl’shore 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 subsca 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 (MIDIJ)—A vessel, other than a “mobile ofTshore drilling unit,” which is capable ofengaging in drilling or workover operations for the exploration or exploitation of subsea mineral resources and is designed and intended for use in US waters, rivers, inland lakes, bays, or sounds. These recommendations apply to all types of MIDU 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.
e) Naval vessels:
I) Noncombatant vessels—-Including all naval auxiliary ships, military supply vessels, and icebrcakcrs.
3.3.2 Non-applIcable facilities and 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 offloading (FPSO). and spar buoy or deep draff caisson vessel. These types of floating facilities are site-specific and not intended for periodic relocation, Other types of floating facilities include permanently moored serni-submersiblcs and shipshape hulls. All of these types of floating facilities produce hydrocarbons from the well and process thcm on board and either store them on board and pump the produced hydrocarbon into a pipeline or directly onto another vessel.
C) Recreational sessels.
NOTE—These recommendations have not been prepared for application for the facilities and vescls listed in item a) item bi. and Item c) because they are outside the scope of this recommended practice and arc 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 ekctncal plant. A non.eihaustis’e list is given below,
a) COMMERCiAL Passenger: Primary load is propulsion (for hulls with electric propulsion). Si,eable loads include pumps and low-voltage lighting and heating/cooling.
It) (‘O.4IMER(’I.4L—Cargo: Primary load is propulsion (for hulls with electric propulsion). Sizcablc loads include material handling and pumps. Material handling may be physically located above or below main deck icyci.
c) CO.4mERCIAL i1.rk: 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 “clean” power is required for the scientific equipment
d) NA4L—Auxiliary: Primary load is propulsion (for hulls with electric propulsion). Sizeablc loads may be similar to either commervial passenger OR commercial wo& depending on application. Special notice should be taken for ocean surveillance, where an abundance of’cIean” power is required fur the scientific equipment.
