4.4

 Safety checks when the inert gas plant is shut down should be as follows:

  • .1 The water supply and water level in the deck seal should be ascertained at regular intervals, at least once per day depending on weather conditions.

  • .2 Check the water level in water loops installed in pipework for gas, water or pressure transducers, to prevent the backflow of hydrocarbon gases into gas-safe spaces.

  • .3 In cold weather, ensure that the arrangements to prevent the freezing of sealing water in the deck seals, pressure/vacuum breakers etc. are in order.

  • .4 Before the pressure in the inerted cargo tanks drops to 100 mm they should be re-pressurized with inert gas.
