3.3 ApplicabilIty
3.3.1 Applicable vessels
The lIlli 45 senes of recommended practices have been prepared for application a broad range of both coniniercnl and inval vessels, as outlined in F ieurc .1, includrnis.
a) Passenger vessels.
I) All vessels of lOt) gross ions or more whose pnnciple purpose is the carrying of pss’s’iengers.
21 Passenger vessels wider 100 gross tons carrying more than six but less than ISO passengers or that has overnight aecomnwdatioivs for less than 50 passengers.
3) Passenger vessels carrying isiure than 154) passengers oe wish ovL’nught accommodations for more than 49 passengers.
b) Cago vessels:
I) Liquid All vessels whose principle purpose is the carrying of combustible, flammable, or lianrdous liquid cargo in bulk (e.g.. crude oil. refined oil gasoline, liquid eheinieah, etc.).
2) Dry: All vessels carrying freight for hire (e.g hulk. canrainenred, automobiles, etc.).
e) Work ve55ls
I) Offshore supply vessels
2) Nautical school vessels.
3) Oceanographic research vessels—All vessels engaged in oceanographic reseaach.
4) Mobile offshore dnlling units (MODIJ)—A vessel other than a “mobile inland drilling unit.” which is capable of engaging its drilling or workoser operaiioixs for the explorations and exploitation of subset mineral resources. These recornnicndatsoas appl to all types of MODUs without production facilities, including, hut not limited to, semi .suhrnersihle units, submersible units, self-elevating or jack-up units, and drill ships and tenders.
5) Mobile inland dnlling units t MItR. t A vessel, other tItan a “rnrilsile otishore drilling unit,” which is capable oferigaging indrillingor workover operations foe rheexploraiion or exploitation of sstbsea mineral resources and is designed and intended for use in US waters, rivers, inland lakes, bays, or souats These recommendations apply to all types of Mll)t I without production berliries, including, but not limited to. inland barges and posted inland barges.
di Miscellaneous ves.sels All vessels not covered in other groups, all tugboats and tow boats, and all seagoing barges not covered in other groups.
e) Naval vessels:
II Nonconsbsstant vessels—Including all naval auxilian ships, military supply vessels, and icehreak ci’s
2) Combatant vessels
3.3,2 Non’applicable facililies and vessels
Vessel classification and facilities the IEEE 45 series recornntendcd practices are nor applicable to:
a) Fixed petnileiim facilities.
hi Floating petroleum facilities—A buoyant faciliry that is securely and substantially nsoored so thai it cannot be nsrsval without a speetal et)wt. The tern includes, hut is not limited to, tension leg plafornis, floating production systems, floating production storage and ofiloading IFPSOk and spar buoy ordcepdra(t caisson sissel. These typesof fissating facilities are site-specificand not intended for periodic relocation. Other types offloatutg facilities include permanently moored semi-submersibles and shipshape hulls. All of these types of tloating facilities produce hydnwarhons 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 sess.els
XOTL These reccanxnenchsions hoe not been prepared far qpticatian foe the facilities and vessels listed in item at arm hi. and lEers t because they sir outssle the seupeof this recomniesded practice and ate cosesed under national reid aitenrat sisal sireidarsti
14 Vessel classification electric load distinctions
For the purposes of this recommended practice, a mator difference between vessel classifications withrn the cununercial sub-clans is the type of electrical load supplied by tlse electric-al plant. A non-eslotustise list is given below.
at COMMERCL4L—Pasn’ngrr: Prirnan load is propulsion (for hulls with electric propulsiont. Siztabk loads include pumps and low-voltage lighting and heating.’cooling.
hi (‘L&4L1ERLL4L—L’wyo: Prirtsars load is propulsion (for hulls with electric propulssror Sizeable loads include material handling and pumps Material handling may he physically located above or below ntarn deck level.
ci COMMERCiAL—Work: 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 at abundance of “clean” power is required for the scientific equipment
di V4AL —Au.sthary: Primary load is propulsion tfor hulls with electric pivipukion t. Size-able loads may be similar to either commercial passenger OR commercial work. dependmg on application. Special notice should be taken fec ocean suneillaisce, w lrere an abundance of”eleaas” power is required for the scientific equipment.
ci XAIAL—Contlra&rni: High priority given to overall system redundancy and decenttalrzed power generation. Primary load may be propulsion I for hulls with electric propulsiont – but not necessarily. Additional design constrainL’r may apply to specific hull airangensents such as electromagnetic interference and stntcture-hoine noise. lioth of these constraints can be addressed w hen creating the electrical distribittion to minimize ads’erse effects.
In addition, all vessels dealing with potentially hazardous materials will have additional system constraints dnven by the nature of the hazard.IEEE 45.4 pdf download.
