Criterion for judgment is made based upon internal vetting criteria of Idemitsu, taking account of all available information including SIRE inspection reports (of Idemitsu Tanker or other OCIMF SIRE submitting members), terminal feedback, Port State Control information and owner's/operator's assessment. Ship's physical conditions (ship's age, SDWT, mooring facilities, parallel body length, etc.) are also taken into consideration.
The system attaches much importance to Idemitsu inspections. It is carried out by Idemitsu's experienced inspectors and obtain extra information such as detailed comments and evaluation, that are not seen in SIRE reports, However, Idemitsu recognizes that the membership's mutual trust in SIRE reports is also necessary to avoid unreasonable overlap of inspections.
SIRE reports are treated as one of the most important basis of judgement in the Idemitsu Vetting.
