6.8 Processor and transmitting device

  6.8.1 The processor of a control section should receive signals from the oil content meter, the flow rate indicating system and the ship's speed indicating system at time intervals not exceeding five seconds and should automatically compute the following:

  • .1 instantaneous rate of discharge of oil in litres per nautical mile; and

  • .2 total quantity of oil discharged during the voyage in cubic metres or litres.

  6.8.2 When the limits imposed by regulation 31.1.4 and 31.1.5 are exceeded, the processor should provide alarms and provide command signals to the overboard discharge control arrangement which will cause the discharge of effluent into the sea to stop.

  6.8.3 The processor should normally include a device for the continuous generation of time and date information. Alternative arrangements for the automatic and continuous reception of time and date information from an external source may be accepted.

  6.8.4 In the event of power failure the processor should retain its memory in respect to computation of the total quantity of oil discharged, time and date. A printout of data should be obtained when the monitoring system is operating with manual override, but this is not required if, when the power fails, the monitoring system activates the overboard discharge control to stop the discharge of effluent.
