Open registries have been criticised, mainly by
trade union organisations based in developed countries, especially those in the European Union, United States, Japan, Canada, or the United Kingdom. One criticism is that shipowners who want to hide their ownership may select a flag-of-convenience jurisdiction which enables them to be legally anonymous. Some ships with flags of convenience have been found engaging in crime, offering substandard working conditions, and negatively impacting the environment, primarily through
illegal, unreported and unregulated fishing. Prior to the implementation of the
International Convention on Tonnage Measurement of Ships, 1969, shipowners may have selected a jurisdiction with measurement rules that reduced the certified
gross register tonnage of a ship, to reduce subsequent port of call dock dues. Such was a consideration when
Carnival Cruise Line changed the flag of the RMS
Empress of Canada in 1972 to that of Panama. In 2011,
Cunard Line registered all its ships in
Bermuda, which, besides other considerations, enabled its ship captains to marry couples at sea. Weddings at sea are described as a lucrative market. Maritime industry practitioners and seafarers from other countries contend that this is a natural product of globalisation. Supporters of the practice, however, point to economic and regulatory advantages, and increased freedom in choosing employees from an international labour pool. Publications from as early as 1962 argue that shipowners from developed countries use the practice to be competitive in a global environment. In 2010 in a message connected to the
World Maritime Day, the Secretary-General of the
International Maritime Organization gave recognition to the present status of the open registries and noted that the seafarers from some developing countries are providing a major source of foreign currency to their home economies: The development of open registries for ships has given the shipping industry the flexibility to recruit its manpower from alternate sources, with the result that developing and newly industrialized countries now provide the majority of seafarers for the entire global fleet – not just for the ships flying their own country's flag.
Legal context International law requires that every merchant ship be registered in a country. A ship operates under the laws of its flag state, and these laws are used if the ship is involved in an admiralty case. A ship's flag state exercises regulatory control over the vessel and is required to inspect it regularly, certify the ship's equipment and crew, and issue safety and pollution prevention documents. The organization which actually registers the ship is known as its registry. Registries may be governmental or private agencies.
Reasons for adopting a flag of convenience The reasons for choosing an open register are varied and include
tax avoidance, and the ability to hire crews from lower-wage countries. National or closed registries typically require a ship be owned and constructed by national interests, and at least partially crewed by its citizens. Conversely, open registries frequently offer on-line registration with few questions asked. The use of flags of convenience lowers registration and maintenance costs, which in turn reduces overall transportation costs. The accumulated advantages can be significant, for example in 1999, 28 of the American company
SeaLand's fleet of 63 ships were foreign-flagged, saving the company up to US$3.5 million per ship every year. Resulting from strong political and public outcry over the
Amoco Cadiz sinking, fourteen European nations signed the 1982
Paris Memorandum of Understanding on Port State Control or Paris MOU. In 2015, member states of the Paris MOU conducted 17,858 inspections with deficiencies, which resulted in 595 detained vessels and 11 banned. Member states of the Tokyo Memorandum of Understanding conducted 17,269 ship inspections in 2015, recording 83,606 deficiencies which resulted in 1,153 detentions. The principle that there be a genuine link between a ship's owners and its flag state dates back to 1958, when Article 5(1) of the
Geneva Convention on the High Seas also required that "the state must effectively exercise its jurisdiction and control in administrative, technical and social matters over ships flying its flag." The principle was repeated in Article 91 of the 1982 treaty called the
United Nations Convention on the Law of the Sea and often referred to as UNCLOS. The Convention for Registration of Ships would require that a flag state be linked to its ships either by having an economic stake in the ownership of its ships or by providing mariners to crew the ships. To come into force, the 1986 treaty requires 40 signatories whose combined tonnage exceeds 25% of the world total. Between 1986 and 2012, 24 countries signed or ratified the treaty. , it has not entered into force. ==History==
