All lubricating oils and jet fuels are acutely water-critical.
Current practice requires full line draining and mopping up of any
water in tanks before loading. Water contamination may occur on inerted
ships due to:
.1 water carry-over from the scrubber and/or deck
water seals due to inadequacies in design or maintenance of the various
drying arrangements, and
.2 condensation of water from warm, fully saturated
flue gas delivered to the tanks.
