(1) Main propulsion, control, steam pipe, fuel
oil, compressed air, electrical and refrigeration systems; auxiliary
machinery; boilers and other pressure vessels; piping and pumping
arrangements; steering equipment and gears, shafts and couplings for
power transmission shall be designed, constructed, tested, installed
and serviced to the satisfaction of the Administration. This machinery
and equipment, as well as lifting gear, winches, fish handling and
fish processing equipment shall be protected so as to reduce to a
minimum any danger to persons on board. Special attention shall be
paid to moving parts, hot surfaces and other dangers.
(2) Machinery spaces shall be so designed as to
provide safe and free access to all machinery and its controls as
well as to any other parts which may required servicing. such spaces
shall be adequately ventilated.
(3)
-
(a) Means shall be provided whereby the operational
capability of the propulsion machinery can be sustained or restored
even though one of the essential auxiliaries becomes inoperative.
Special consideration shall be given to the functioning of:
-
(i) the arrangements which supply fuel oil pressure
for main propulsion machinery;
-
(ii) the normal sources of lubricating oil pressure;
-
(iii) the hydraulic, pneumatic and electrical
means for the control of main propulsion machinery including controllable
pitch propellers;
-
(iv) the sources of water pressure for main propulsion
cooling systems; and
-
(v) an air compressor and an air receiver for
starting or control purposes,
-
Provided that the Administration may, having regard to overall
safety considerations, accept a partial reduction in capability in
lieu of full normal operation.
-
(b) Means shall be provided whereby the machinery
can be bought into operation from the dead ship condition without
external aid.
(4) Main propulsion machinery and all auxiliary
machinery essential to the propulsion and the safety of the vessel
shall, as fitted, be capable of operating whether the vessel is upright
or listed up to 15° either way under static conditions and up
to 22.5° either way under dynamic conditions, i.e. when rolling
either way and simultaneously pitching (inclined dynamically) up to
7.5° by bow or stern. The Administration may permit deviation
from these angles, taking into consideration the type, size and service
conditions of the vessel.
(5) Special consideration shall be given to the
design, construction and installation of propulsion machinery systems
so that any mode of their vibrations shall not cause undue stresses
in such machinery systems in the normal operating ranges.
(6) The design and construction of electrical
installations shall be such as to provide:
-
(a) the services necessary to maintain the vessel
in normal operational and habitable conditions without having recourse
to an emergency source of power;
-
(b) the services essential to safety when failure
of the main source of electrical power occurs; and
-
(c) protection of the crew and vessel from electrical
hazards.
Periodically unattended machinery spaces
(8) Regulations 19 to 24 shall apply, in addition
to regulations 3 to 18 and V/1 to V/44, to vessels with periodically
unattended machinery spaces.
(9) Measures shall be taken to the satisfaction
of the Administration to ensure that all equipment is functioning
in a reliable manner in all operating conditions, including manoeuvring,
and that arrangements to the satisfaction of the Administration are
made for regular inspections and routine tests to ensure continuous
reliable operation.
(10) Vessels shall be provided with documentary
evidence to the satisfaction of the Administration of their fitness
to operate with periodically unattended machinery spaces.
