History
In 1978, a number of European countries agreed in The Hague on a memorandum for the audit of labour conditions on board vessels as to whether they were in accordance with the rules of the ILO. After the '' Amoco Cadiz'' sank that year, it was decided to also audit safety and pollution practices. To this end, in 1982 fourteen European countries agreed on the Paris Memorandum of Understanding on Port State Control (Paris MoU) to establish port state control. Nowadays 26 European countries and Canada are signatories of Paris MoU. PSC was a reaction to the failure of those flag states especially flag of convenience states that had delegated their survey and certification responsibilities toInspection and enforcement
The port state control (PSC) makes inspection of ships in port, taken by a port state control officer (PSCO). Annual report of Paris MoU reported that a total of 74,713 deficiencies were recorded during port state control inspections in 2007, which deficiencies resulted in 1,250 detentions that year.Paris Mou (2007), "Deficiencies per major category", Annual Report 2007 – Paris MoU on Port State Control, Month Date, pp. 22–23. Detention of the ship is the last course of action that a PSCO would take upon finding deficiencies aboard the vessel. Courses of action a PSCO may impose on a ship with deficiencies (in order of ascending gravity) are:Özçayir, Z.O. (2004), "Practical Implication of Port State Control: The Contractual Effect of Port State Control Detentions". In Mitropoulos, E.E. Port State Control, 2nd ed, LLP, London, pp. 509, 520–521 # Deficiencies can be rectified within 14 days for minor infractions. # Under specific conditions, deficiencies can be rectified when the ship arrives at the next port. # Deficiencies must be rectified before the ship can depart the port. # Detention of the ship occurs.Sanctioning
Port states can also (besides detention etc.) sanction violations with fines. Port states can also in certain cases, for example if a ship violates the 0.5% sulphur limit of MARPOL Annex VI, assert jurisdiction for such violations which occur on the high seas. The extraterritorial jurisdictional basis for such enforcement and sanctioning is found within the special provisions of part XII of the United Nations Convention on the Law of the Sea ( UNCLOS).Jesper Jarl Fanø (2019).
