Furthermore, a total of six vessels remain under detention at the end of July.

In June, the total number of detained ships in UK ports was 11, with seven new detentions.

The UK is part of a regional agreement on port state control known as the Paris Memorandum of Understanding on Port State Control (Paris MOU) and information on all ships that are inspected is held centrally in an electronic database known as THETIS. This allows the ships with a high risk rating and poor detention records to be targeted for future inspection.

Inspections of foreign flagged ships in UK ports are undertaken by surveyors from the Maritime and Coastguard Agency. When a ship is found to be not in compliance with applicable convention requirements, a deficiency may be raised. If any of their deficiencies are so serious they have to be rectified before departure, then the ship will be detained.

The notes provided on the list of detentions include full details of the ship, the operation company, the classification society and the recognised Organisation and the performance of flag State (white – grey – black list assessed by the Paris MoU).
