M. Environment

    This action is one of a category of actions that do not
individually or cumulatively have a significant effect on the human
environment. A preliminary Record of Environmental Consideration
supporting this determination is available in the docket. For
instructions on locating the docket, see the ADDRESSES section of this
preamble. This proposed rule would be categorically excluded under
paragraph L57 of Appendix A, Table 1 of DHS Instruction Manual 023-01-
001-01, Rev. 01. Paragraph L57 pertains to regulations concerning
manning, documentation, admeasurement, inspection, and equipping of
vessels.
    This proposed rule involves incorporating by reference several
updated electrical engineering standards along with removing several
outdated or unnecessarily prescriptive electrical engineering
regulations. We seek any comments or information that may lead to the
discovery of a significant environmental impact from this proposed
rule.

Subpart 111.51--Calculation of Short-Circuit Currents and
Coordination of Overcurrent Protective Devices

Sec.  111.51-1  General.

    Electrical installations must be protected against short circuits,
by appropriate devices. The selection, arrangement and performance of
various protective devices must provide coordinated automatic
protection and selective operation in order to provide continuity of
service for equipment vital to the propulsion, control or safety of the
vessel under short-circuit conditions through coordination and
selective

operation of overcurrent protective devices.

Sec.  111.51-2  Short-circuit calculations

    (a) The available short-circuit current must be computed--
    (1) From the aggregate contribution of all generators that can
simultaneously operate in parallel;
    (2) From the largest probable motor load; and
    (3) With a three-phase fault on the load terminals of the
protective device.
    (b) The calculated currents must be used to select suitably rated
equipment and to allow the selection and setting of protective devices.

Sec.  111.51-3  Short-circuit calculations for systems below 1500
kilowatts.

    The following short-circuit assumptions must be made for a system
with an aggregate generating capacity below 1500 kilowatts, unless
detailed computations in accordance with Sec.  111.51-4 are submitted:
    (a) The maximum short-circuit current of a direct current system
must be assumed to be 10 times the aggregate normal rated generator
currents plus 6 times the aggregate normal rated currents of all motors
that may be in operation.
    (b) The maximum asymmetrical short-circuit current for an
alternating current system must be assumed to be 10 times the aggregate
normal rated generator currents plus 4 times the aggregate normal rated
currents of all motors that may be in operation.
    (c) The average asymmetrical short circuit current for an
alternating-current system must be assumed to be 8\1/2\ times the
aggregate normal rated generator currents plus 3\1/2\ times the
aggregate normal rated currents of all motors that may be in operation.

Sec.  111.51-4  Short-circuit calculations for systems 1500 kilowatts
or above.

    Short-circuit calculations must be submitted for systems with an
aggregate generating capacity of 1500 kilowatts or more by utilizing
one of the following methods:
    (a) Exact calculations using actual impedance and reactance values
of system components.
    (b) Estimated calculations using IEC 61363-1:1998 (incorporated by
reference; see 46 CFR 110.10-1) for AC systems and IEC 61660-1:1997 for
DC systems.
    (c) The estimated calculations using a commercially established
analysis procedure for utility or industrial applications.

Sec.  111.51-5  Protection of vital equipment.

    (a) The coordination of overcurrent protective devices must be
demonstrated for all potential plant configurations.
    (b) Protective relays and overcurrent protective devices must be
installed so that:
    (1) A short-circuit on a circuit that is not vital to the
propulsion, control, or safety of the vessel does not trip equipment
that is vital; and
    (2) A short-circuit on a circuit that is vital to the propulsion,
control, or safety of the vessel is cleared only by the protective
device that is closest to the point of the short-circuit.

106. Add Sec.  112.05-07 to subpart 112.05 to read as follows:

Sec.  112.05-7  Use of emergency generator in port.

    The emergency generator may be used during lay time in port for
supplying power to the vessels, provided the following:
    (a) The fuel oil tank for the emergency generator prime mover must
be appropriately sized and provided with a level alarm, which is to be
set to alarm at a level where there is sufficient fuel oil capacity for
the emergency services for the period of time required by Sec.  112.05-
5(a).
    (b) The emergency generator prime mover is to be rated for
continuous service.
    (c) The prime mover is to be fitted with alarms, displays and
automatic shutdown arrangements that meet ABS Marine Vessel Rules,
section 4-8-2/5.19 Table 2, except that for fuel oil tank low-level
alarm, in paragraph (a) of this section is to apply instead. The
displays and alarms are to be provided in the centralized control
station. Monitoring at the engineers' quarters must meet ABS Marine
Vessel Rules, section 4-9-6/19.
    (d) The emergency generator room is to be fitted with fire
detectors. Where the emergency generator is located in a space
separated from the emergency switchboard, fire detectors are to be
located in each space. The fire detection and alarm system must meet
the requirements of 46 CFR subpart 113.10.
    (e) The power supply circuits, including control and monitoring

circuits, for the use of an emergency generator in port are to be so
arranged and protected that any electrical fault, except for the
emergency generator and the emergency switchboard, will not affect the
operation of the main and emergency services.
    (f) Means are to be provided to readily change over to emergency
operation.
    (g) The generator is to be safeguarded against overload by
automatically shedding such other loads so that the supply to the
required emergency loads is always available.
    (h) Operational instructions such as that on the fuel oil tank
level, harbor/seagoing mode changeover arrangements, etc. are to be
provided on board. Before the vessel is under way, all valves,
switches, etc., are to be in the positions for the intended mode of
operation of the emergency generator and the emergency switchboard.
Such instructions are to be distinctly posted at the emergency
generator room. Planned maintenance is to be carried out only while in
port.
