During April, there were two new detentions of foreign flagged vessels in a UK port. 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 each month. 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.
