Best and worst performers

The Isle of Man flag topped the white list with just five detentions arising from 657 inspections by the Paris MoU between 2016 and 2018.

At the bottom of the black list, the Republic of Congo flag was inspected 98 times over the same timeframe, resulting in 26 vessels being detained.

Earlier this month, the Paris MoU banned two Comoros-flagged cargoships for failing three port state checks in three years.

The Comoros flag is one of the five worst performing flags on the Paris MoU's black list.
