3.5.3 The cargo transfer rate should not exceed
the lesser of the maximum vapour processing rate for the vapour emission
control system (accounting for vapour generation and any inerting,
enriching, or diluting gas which may be added to the system) or the

3.5.4 The high and low pressure alarm sensor set
points should be verified as being matched to the tanker's acceptable
