The Paris MoU on Port State Control has updated its White, Gray, and Black lists and, from 1 July 2021, the 27 national maritime administrations that are parties to the agreement will be using an updated version of the list in targeting ships for inspections.
For several years the Paris MoU Committee has closely monitored the performance of recognized organizations (ROs), mostly classification societies 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 2020, 32 ROs were recorded on the performance list.
