6.2.1 The layout of the shipboard installation
should be arranged so that the overall response time between an alteration
in the mixture being pumped and the alteration in the meter reading
should be as short as possible and in any case not more than 40 seconds,
to allow for remedial action being taken before the oil content of
the mixture being discharged exceeds the permissible limit.
6.2.2 The arrangement on board ship for the extraction
of samples from the discharge line to the meter should give a truly
representative sample of the effluent. Sampling points should be arranged
in all discharge pipes which have to be monitored for compliance with
the Convention.
6.2.3 Where the Convention requires records, the
oil content meter should be so designed and constructed that any operation
carried out on them is automatically registered by the meter.
