Flags, whose ships were involved in 30 or more inspections during the period, are included in the list.
The black-grey-white list for 2017-2019 consists of 69 flags:
- The number of flags in the black list is 10, two flags less than the last year.
- The number of flags on the grey list increased from 16 to 19 during the reporting period.
- The white list includes 40 flags, same as the last year.
The Port State Control Committee adopted the same method as used by the Paris MoU for assessment of performance of flags.
Compared to the calculation method of previous year, this system has the advantage of providing an excess percentage that is significant and also reviewing the number of inspections and detentions over a 3-year period at the same time, based on binomial calculus.
