Voorbeeldzinnen

1. Suction pump
2. .3.2 provisions for the measurement of oil temperature are provided on the suction pipe of the fuel pump;
3. The emergency pump, its seawater inlet and suction and delivery pipes and isolating valves shall be located outside the machinery space.
4. .2.5 In addition to the direct bilge suction or suctions required by paragraph .2.4 a direct emergency bilge suction fitted with a non-return valve shall be led from the largest available independent power driven pump to the drainage level of the machinery space; the suction shall be of the same diameter as the main inlet to the pumps used.
5. .2.5 In addition to the direct bilge suction or suctions required by paragraph .2.4 a direct emergency bilge suction fitted with a non-return valve shall be led from the largest available independent power-driven pump to the drainage level of the machinery space; the suction shall be of the same diameter as the main inlet to the pumps used.
6. The sample can be cooled with liquid nitrogen or dry ice, but care should be taken to avoid condensation of air or pump-fluid. With the valve over the sample vessel open, suction is applied for several minutes to remove the air.
7. If this arrangement cannot be made, the sea-chest may be fitted in the machinery space if the valve is remotely controlled from a position in the same compartment as the emergency pump and the suction pipe is as short as practicable.
8. Exceptionally, short lengths of the emergency fire pump suction and discharge piping may penetrate the machinery space if it is impracticable to route it externally provided that the integrity of the fire main is maintained by the enclosure of the piping in a substantial steel casing.
9. NEW CLASS B, C AND D SHIPS CONSTRUCTED BEFORE 1 JANUARY 2003: .1.2 Where more than one independent fire pump is required, isolating valves to separate the section of the fire main within the machinery space containing the main fire pump or pumps from the rest of the fire main shall be fitted in an easily accessible and tenable position outside this machinery space. The fire main shall be so arranged that when the isolating valves are shut all the hydrants on the ship, except those in the machinery space referred above, can be supplied with water by a fire pump not located in this machinery space through pipes which do not enter this space. Exceptionally, short lengths of the emergency fire pump suction and discharge piping may penetrate the machinery space if it is impracticable to route it externally provided that the integrity of the fire main is maintained by the enclosure of the piping in a substantial steel casing. NEW CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:
