Artikel 41

(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 require 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.

(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;
(b) Means shall be provided whereby the machinery can be brought 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 degrees either way under static conditions and up to 22½ degrees either way under dynamic conditions, i.e. when rolling either way and simultaneously pitching (inclined dynamically) up to 7½ degrees 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.

(7) The Administration shall be satisfied that Regulations 54 to 56 are uniformly implemented and applied.
(8) Regulations 57 to 62 shall apply, in addition to Regulations 41 to 56 and 63 to 105, 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.
