Specifically, during September, there were two new detentions of foreign flagged vessels in a UK port. Seven vessels remained under detention from previous months. A total of six vessels remain under detention at the end of September.
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.
