1 Emergency generating sets shall be capable of
being readily started in their cold condition at a temperature of
0°C. If this is impracticable, or if lower temperatures are likely
to be encountered, provision acceptable to the Administration shall
be made for the maintenance of heating arrangements, to ensure ready
starting of the generating sets.
2 Each emergency generating set arranged to be
automatically started shall be equipped with starting devices approved
by the Administration with a stored energy capability of at least
three consecutive starts. A second source of energy shall be provided
for an additional three starts within 30 min unless manual starting
can be demonstrated to be effective.
-
2.1 Ships constructed on or after 1 October 1994,
in lieu of the provision of the second sentence of paragraph 2, shall
comply with the following requirements:
The source of stored energy shall be protected to preclude critical
depletion by the automatic starting system, unless a second independent
means of starting is provided. In addition, a second source of energy
shall be provided for an additional three starts within 30 min unless
manual starting can be demonstrated to be effective.
3 The stored energy shall be maintained at all
times, as follows:
-
.1 electrical and hydraulic starting systems shall
be maintained from the emergency switchboard;
-
.2 compressed air starting systems may be maintained
by the main or auxiliary compressed air receivers through a suitable
non-return valve or by an emergency air compressor which, if electrically
driven, is supplied from the emergency switchboard;
-
.3 all of these starting, charging and energy
storing devices shall be located in the emergency generator space;
these devices are not to be used for any purpose other than the operation
of the emergency generating set. This does not preclude the supply
to the air receiver of the emergency generating set from the main
or auxiliary compressed air system through the non-return valve fitted
in the emergency generator space.
4.1 Where automatic starting is not required,
manual starting is permissible, such as manual cranking, inertia starters,
manually charged hydraulic accumulators, or powder charge cartridges,
where they can be demonstrated as being effective.
4.2 When manual starting is not practicable, the
requirements of paragraphs 2 and 3 shall be complied with except that
starting may be manually initiated.
