The Marine Department has a responsibility to ensure that non-Hong Kong registered ships visiting Hong Kong comply with the requirements of various international maritime conventions. To discharge this function, officers of the Department carry out PSC inspections on ships visiting Hong Kong in accordance with provisions of IMO Resolution A.1206(34) and Tokyo MOU Port State Control Manual. There are no fees for the initial inspections. If serious deficiencies are noticed, the ship will be detained under the PSC regime, and the ship's agent/owner, classification society and flag State will be notified of the detention as well as the requirement for rectification. Generally, serious deficiencies affecting the seaworthiness of the vessel and/or the safety of the crew and/or causing damages to the marine environment are required to be rectified prior to the ship's departure. After receiving the completed application and re-inspection notice from the representative of the detained ship, the Marine Department will arrange a re-inspection on or before the next working day to confirm if the deficiencies of the ship have been rectified. The re-inspection fees are charged at an hourly rate for work done.
