Foreign flagged ships detained in the UK during October 2023 under Paris MOU.

November 16, 2023 Uncategorized

The Maritime and Coastguard Agency (MCA) announced today that four foreign flagged ship remained under detention in UK ports at the end of October after failing Paris MOU Port State Control (PSC) inspection.


During October, there were four new detentions of a foreign flagged vessel in a UK port.

  1. In response to one of the recommendations of Lord Donaldson’s inquiry into the prevention of pollution from merchant shipping, the Maritime and Coastguard Agency (MCA) publishes details of the foreign flagged vessels detained in UK ports under the Paris MOU regime each month.
  2. 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.
  3. 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, deficiencies may be raised. Depending on the inspection findings, the vessel may be liable for detention in these cases.
