VIQ (Vessel Inspection Questionnaire)
The Vessel Inspection Questionnaire (VIQ) benchmarking database is based on the current SIRE VIQ and has been developed by INTERTANKO's Vetting Committee and TMSA Working Group. The VIQ benchmarking database uses a simple traffic light system, incorporating either red or green (as well as a numerical value) to indicate if the number of your fleet average, SIRE VIQ observations, as recorded by the SIRE inspector, are above or below the number of SIRE VIQ observations recorded in the database for the collective of the INTERTANKO fleet.
Red = above INTERTANKO fleet average
Green = below INTERTANKO fleet average
There are three main columns shown in the database based upon the SIRE VIQ chapters, these are repeated, in view of the fact that chapter 8 of the SIRE VIQ includes a different chapter for "petroleum", "chemical" and "gas". Thus, it is necessary to complete the relevant column as appropriate to your fleet type.
Calculation of your Fleet Average Deficiency
The following formula will need to be used to calculate your Fleet average deficiency for each SIRE VIQ chapter:
"Total number of deficiencies per SIRE VIQ chapter, divided by Total number of inspections"
The time period used should be any rolling period of 12 months.
