8.3 Protection against flooding

  8.3.1 Bilge wells in machinery spaces should be located and monitored in such a way that the accumulation of liquids is detected at normal angles of trim and heel; they should be large enough to accommodate easily the normal drainage during the unattended period.

  8.3.2 In cases where the bilge pumps start automatically, means should be provided to indicate if the influx of liquid is greater than the pump capacity or if the pump is operating more frequently than would normally be expected. In these cases, smaller bilge welts to cover a reasonable period of time may be permitted. Where automatically controlled bilge pumps are provided, special attention should be given to oil pollution prevention requirements.

  8.3.3 The controls of any valve serving a sea inlet, a discharge below the water line or a bilge injection system should be so sited as to allow adequate time for operation in case of influx of water to the space, having regard to the time which could be taken to reach and operate such controls. The level to which the space could become flooded with the unit in the fully loaded condition should be considered and this may require control from a position above such level.
