Where the freeboard to the bulkhead deck is such that the deck edge is not immersed when the ship heels 5 degrees either way, the required drainage shall be by means of a suitable number and size of deck scuppers discharging directly overboard fitted in accordance with Merchant Shipping (Load Line) rules 1979. In all other cases, internal drainage shall be led to a suitable space or spaces of adequate capacity having a high water-level alarm and provided with a suitable arrangements for discharge overboard.

        (7)The scuppers of cargo spaces intended for the carriage of motor vehicles with fuel in their tanks for their own propulsion shall not be led to machinery or other spaces where sources of ignition may be present.

        (8)The bilge pumping arrangements for cargo spaces intended to contain flammable or toxic liquids shall be designed so that inadequate pumping of such liquids through the main bilge system or any other system connected to a pump located in a machinery space can be prevented. Additional means of draining considers their provided if the Director General considers their provision necessary taking into consideration the quantity and characteristics of the liquid and their location.

          (h)the mechanical air supply for boilers,
          (i)an air compressor and receiver for starting or control purposes,
          (j)the hydraulic, pneumatic, or electrical means for control of main propulsion machinery including controllable pitch propellers, or
          (k)any other auxiliary system essential for propulsion ;

      Provided that the Chief Surveyor with the Government of India may for the purpose of this sub rule, if satisfied that it is safe so to do, permit a partial reduction in propulsion capability from normal operation.

        (4)The main and auxiliary machinery essential for the propulsion and safety of the ship shall be provided with effective means of control and the machinery shall be capable of being brought into operation when initially no power is available in the ship.

        (5)Where risk from over-speeding of machinery should otherwise exist, two independent means of control, shall be provided to ensure that the safe speed is no exceeded ;
        Provided that the Chief Surveyor with the Government of India may permit a single means of limiting the speed of machinery where he considers it safe to do so.

        (6)Where main or auxiliary machinery or any parts of such machinery are subject to internal pressure, those parts shall, before being put into service for the first time, be subjected to a hydraulic test to a pressure suitably in excess of the working pressure having regard to,

          (a)the design and the material of which they are constructed.
          (b)the purpose for which they are intended to be used, and
          (c)the working conditions under which they are intended to be used: 


        and such parts shall be maintained in an efficient condition.

      (7)Main propulsion machinery and the all auxiliary machinery essential to the propulsion and the safety of the ship shall be designed to operate when the ship in upright and when inclined at angle of list up to and including 15 degrees either way under dynamic conditions (rolling) and simultaneously inclined dynamically (pitching) 7.5 degrees by bow or stern:

      Provided that the Chief Surveyor with the Government of India may permit a reduction in the angles specified in the sub rule taking into considerations the type, size and service conditions of the ship.

      (8)Access shall be provided to facilitate the cleaning inspection and maintenance of main propulsion and auxiliary machinery including boilers and pressure vessels.

      13. Machinery--

      (1) In every cargo ship, the propulsion machinery systems shall be designed constructed and installed so that undue stress due to vibration is not induced during normal operation.

        (2) All gearing and every shaft and coupling used for transmission of power essential for the propulsion and safety of the ship or for the safety of persons on board shall be so designed and constructed that they will withstand the maximum working stresses to which they will be subjected to in all service conditions taking into account the type of engines by which they are driven or of which they form part.

        (3) Every internal combustion engine having a cylinder diameter of 200 millimeters or more or a crankcase volume of 0.6 cubic meters or more shall be provided with crankcase explosion relief values of a suitable type having sufficient area to relieve values of a suitable type hang sufficient area to relieve abnormal pressure in the crankcase. The explosion relief values shall be arranged or provided with means to ensure that any discharge from them is so directed as to minimize the possibility of injury to personnel.

        (4)(1) Every main propulsion turbine and, where applicable, main internal combustion propulsion machinery and auxiliary machinery shall be provided with automatic shut-off arrangements that will operate in the case of failures, such as a lubricating oil supply failure, which could leas rapidly to complete breakdown, serious damage or explosion ;

      Provided that the Chief Surveyor with the Government of India may if satisfied that other arrangements provided in the ship is sufficient having regard to the size and type of the machinery, permit fuel arrangements in place of arrangements specified in this sub-rule.

      14. Means of manoeuvring and going astern-- 

      (1) Every cargo ship shall have sufficient power for going astem to secure proper control of the ship in all circumstances. The ability of the propelling machinery to reverse the direction of thrust of the propeller in sufficient time, so as to bring the ship to rest from maximum ahead service speed and the effectiveness of any supplementary means of stopping or maneuvering the ship shall be demonstrated and recorded.

      (2) Every ship with multiple propellers shall undergo trials to determine the ability of the ship to maneuver with one propeller inoperative.
