Inert gas system failure

摘要

After arriving at the discharge terminal, a pre-discharge inspection consisting of the International Safety Guide for Oil Tankers and Terminals (ISGOTT) ship-shore checklist and a pre-discharge conference were completed before beginning line clearance and discharge of gasoline feedstock. The inspection and conference recorded that the equipment was functional and the vessel was operationally ready for discharge. Line clearance was undertaken for a 45-minute period during which the inert gas system (IGS) was not run. Shortly after completion of the line clearance, the terminal indicated that it was ready for discharge. The chief officer started the IGS and the main cargo discharge pump sequentially. However, the high scrubber water level (HSWL) alarm of the IGS failed, causing the scrubber water pump to trip.
