The “White, Grey and Black (WGB) List” presents the full spectrum, from  flags with a high performance 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 over a 3-year rolling period for flags with at least 30 inspections in the period. The “White List” represents flags with a consistently high performance record. Flags with an average performance are shown on the “Grey List”.


  • On the three lists to be used for the calculation of the Ship Risk Profile form 1 July 2018, a total number of 73 flags are listed:
    -40 on the “White List”,
    -20 on the “Grey List” and
    -13 on the “Black list”.
  • In last year’s list the number of flags listed also 73 flags
    -42 on the “White List”,
    -19 on the “Grey List” and
    -12 on the “Black List”.
  • Compared to last year’s list, the number of flags on the “White List” has decreased by two
    -The Republic of Korea has moved back to the “White list” after one year on the “Grey List”.
    -Poland has entered the “White List” as well.
  • On this year’s “Grey List”, a total number of 20 flags are recorded. Last year the “Grey List” lists 19 flags.
  • New on the “Grey List” are the Islamic Republic of Iran, Kazakhstan, the Russian Federation and the United States of America, which were on the “White List” last year.
  • From being a non-listed flag last year, Tuvalu is now on the “Grey List”.
  • New on the “Black List” is Ukraine.

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.


To calculate the performance of the ROs, the same formula to calculate the excess factor of the flags is used. A minimum number of 60 inspections per RO are needed before the performance is taken into account for the list. In the RO performance table to be used for the calculation of the Ship Risk Profile from 1 July 2018, 34 ROs are listed.

  • Compared with last year’s performance level, a small shift in RO performance in 2017 can be noticed. This year three ROs are in the very low performing position against none last year.
  • Three ROs  are in the low performing positions compared to four in the last year and
  • 17 ROs are in the medium position of the list compared to 19 in the last year.
  • Out of 685 detentions recorded in 2017, 99 or 14.5% were considered RO related compared to 13.9% in 2016. (When one or more detainable deficiencies are attributed to an RO in accordance with the Paris MoU criteria, this is recorded as “RO responsible” and the RO is informed.)

On 1 July 2018, the performance lists will be used for calculating the Ship Risk Profile. Flags on the “Grey List” and “Black List” will be subject to  more stringent banning measures which are in force since 1 January 2011.
