All deficiencies should be rectified before departure.
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.
When applicable, the list includes those passenger craft prevented from operating under the provisions of the EU Directive on Mandatory Surveys for the safe operation of regular ro-ro ferry and high speed passenger craft services (1999/35/EU).
