PART 110--GENERAL PROVISIONS--Table of Contents
 
                     Subpart 110.25--Plan Submittal
 
Sec. 110.25-1  Plans and information required for new construction.


    The following plans, if applicable to the particular vessel, must be 
submitted for Coast Guard review in accordance with Sec. 110.25-3:
    Note: A Navigation and Vessel Inspection Circular on the Subject of 
``Coast Guard Review of Merchant Vessel Plans and Specifications'' is 
available from the offices listed in Sec. 110.25-3. The Circular 
recommends practices and procedures for plan submittals.
    (a) Elementary one-line wiring diagram of the power system, 
supported, by cable lists, panelboard summaries, and other information 
including--
    (1) Type and size of generators and prime movers;
    (2) Type and size of generator cables, bus-tie cables, feeders, and 
branch circuit cables;
    (3) Power, lighting, and interior communication panelboards with 
number of circuits and rating of energy consuming devices;
    (4) Type and capacity of storage batteries;

[[Page 210]]

    (5) Rating of circuit breakers and switches, interrupting capacity 
of circuit breakers, and rating or setting of overcurrent devices;
    (6) Computations of short circuit currents in accordance with 
Subpart 111.52; and
    (7) Overcurrent protective device coordination analysis for each 
generator distribution system of 1500 kilowatts or above that includes 
selectivity and shows that each overcurrent device has an interrupting 
capacity sufficient to interrupt the maximum asymmetrical short-circuit 
current available at the point of application.
    (b) Electrical plant load analysis including connected loads and 
computed operating loads for each condition of operation.
    (c) Elementary and isometric or deck wiring plans, including the 
location of each cable splice, a list of symbols, and the manufacturer's 
name and identification of each item of electrical equipment, of each--
    (1) Steering gear circuit and steering motor controller;
    (2) General emergency alarm system;
    (3) Sound-powered telephone or other fixed communication system;
    (4) Power-operated boat winch;
    (5) Fire detecting and alarm system;
    (6) Smoke detecting system;
    (7) Electric watertight door system;
    (8) Fire door holding systems;
    (9) Public address system;
    (10) Manual alarm system; and
    (11) Supervised patrol system.
    (d) Deck wiring or schematic plans of power systems and lighting 
systems, including symbol lists, with manufacturer's name and 
identification of each item of electric equipment, and showing:
    (1) Locations of cables;
    (2) Cable sizes and types;
    (3) Locations of each item of electric equipment;
    (4) Locations of cable splices.
    (e) Switchboard wiring diagram.
    (f) Switchboard material and nameplate list.
    (g) Elementary wiring diagram of metering and automatic switchgear.
    (h) Description of operation of propulsion control and bus transfer 
switchgear.
    (i) For vessels with hazardous locations for which part 111, subpart 
111.105, is applicable, plans showing the extent and classification of 
all hazardous locations, including information on--
    (1) Equipment identification by manufacturer's name and model 
number;
    (2) Equipment use within the system;
    (3) Cable parameters;
    (4) Equipment locations;
    (5) Installation details; and
    (6) A certificate of testing, and listing or certification, by an 
independent laboratory, where required by the respective standard.
    (j) Plans and installation instructions for each approved component 
of an intrinsically safe system listed or certified by an independent 
laboratory (see Sec. 111.105-11 of this chapter).
    (k) Motor starter elementary wiring diagram, enclosure drawing, and 
starter application.
    (l) Plans and information sufficient to evaluate equipment to be 
considered for equivalency under Sec. 110.20-1.
    (m) Plans and information sufficient to evaluate equipment or 
systems required to meet the specifications of this Subchapter but not 
to be approved by the Commandant.

    Note to paragraph (m):
    This equipment evaluation is generally performed by the Commanding 
Officer, Marine Safety Center and includes items such as cable splices, 
signalling lights, shore connection boxes, submersible pumps, engine 
order telegraph systems, shaft speed and thrust indicator systems, and 
steering gear failure alarm systems.

    (n) Plans and information sufficient to evaluate equipment required 
by this subchapter to meet a reference standard or military 
specification.

    Note to paragraph (n):
    This equipment evaluation is generally performed by the Commanding 
Officer, Marine Safety Center, and includes items such as circuit 
breakers, switches, lighting fixtures, air heating equipment, busways, 
outlet boxes, and junction boxes. Items required to meet an IEEE, IEC, 
NEMA, UL, ANSI, or other industry standard or a military specification 
are considered acceptable if manufacturer's certification of compliance 
is indicated on a material list or plan. However, if the standards 
require third-party testing and listing or certification, proof of 
listing or certification by an independent laboratory must also be 
submitted.
