The “White, Grey and Black (WGB) List” presents the full spectrum, from quality flags to
flags with a poor performance that are considered high or very high risk. It is based on the
total number of inspections and detentions during a 3-year rolling period for flags with at
least 30 inspections in the period.

The “White List” represents quality flags with a consistently low detention record.

Flags with an average performance are shown on the “Grey List”. Their appearance on this
list may serve as an incentive to improve and move to the “White List”. At the same time
flags at the lower end of the “Grey List” should be careful not to neglect control over their
ships and risk ending up on the “Black List” next year.

Regarding the “White, Grey and Black List” for 2021, a total number of 68 flags are listed:
40 on the “White List”, 21 on the “Grey List” and 7 on the “Black List”. In 2020 the total
number of flag States on the list was 70 of which 39 on the “White List”, 22 on the “Grey List” and 9 on the “Black List”.

For several years the Committee has closely monitored the performance of ROs acting on
behalf of flag States. To calculate the performance of ROs, the same formula to calculate
the excess factor of the flags is used. A minimum number of 60 inspections per RO is needed before the performance is taken into account for the list. In 2021 33 ROs were recorded on the performance list.

Compared to last year, the RO performance level is at a similar level. It is noteworthy that in the last two years no ROs have been categorised as performing “very low”.

Details of the responsibility of ROs for detainable deficiencies have been published since
1999. When one or more detainable deficiencies are attributed to an RO in accordance with the Paris MoU criteria, it is recorded “RO responsible”. Out of 528 detentions recorded in
2021, 64 (12%) were considered RO related (11% in 2020).

From the 1st of July 2022 the new performance lists will be used for calculating the Ship
Risk Profile.
