31-449: A classification certificate issued by a classification society recognised by the proposed ship register is required for a ship's owner to be able to register the ship and to obtain marine insurance on the ship, and may be required to be produced before a ship's entry into some ports or waterways, and may be of interest to charterers and potential buyers. To avoid liability, classification societies explicitly disclaim responsibility for

62-609: A day. Ships operated illegally, such as by pirates , or narco-submarines , are not normally registered by the operators (although a registered ship may be captured or used covertly for illegal purposes). Det Norske Veritas Det Norske Veritas ( DNV ), formerly DNV GL , is an international accredited registrar and classification society headquartered in Høvik, Norway . DNV provides services for several industries, including maritime , oil and gas , renewable energy , electrification, and healthcare . As of 10 January 2024,

93-580: 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. To date, only 14 countries have signed the treaty. National or closed registries typically require that a ship be owned by national interests, and at least partially crewed by its citizens. Open registries do not have such requirements; some offer on-line registration, and one guaranteed completion in less than

124-529: A registration fee. There must be a "genuine link" between a vessel and its flag state. Article 5(1) of the Geneva Convention on the High Seas of 1958, which came into effect in 1962, requires that "the state must effectively exercise its jurisdiction and control in administrative, technical and social matters over ships flying its flag." There are 63 states party to that Convention. The principle

155-581: Is a ship's flag state and determines its nationality as well as which country's laws govern its operation and the behavior of its crew. A country will specify legal requirements for registration of a ship in its domestic laws, for example, in the UK, the Merchant Shipping Act 1995 details British law on entitlement for ship registration, including qualifications, pre-conditions and the machinery for registration. Each registry has its own rules as to

186-565: Is in compliance with the required codes. This is in part related to legal liability of the classification society. However, each of the classification societies has developed a series of notations that may be granted to a vessel to indicate that it is in compliance with some additional criteria that may be either specific to that vessel type or that are in excess of the standard classification requirements. See Ice class as an example. There have always been concerns that competitive pressure might lead to falling standards – as expressed for example by

217-516: Is proof of ownership of the vessel. International law requires that every ship be registered in a country, called its flag state . A ship is subject to the law of its flag state. It is usual to say that the ship sails under the flag of the country of registration. 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

248-488: Is the origin of the well-known expression 'A1', meaning 'first or highest class'. The purpose of this system was not to assess safety, fitness for purpose or seaworthiness of the ship. It was to evaluate risk. Samuel Plimsoll pointed out the obvious downside of insurance: The first edition of the Register of Ships was published by Lloyd's Register in 1764 and was for use in the years 1764 to 1766. Bureau Veritas (BV)

279-679: The European Commission . To counteract class hopping, in 2009, the International Association of Classification Societies ( IACS ) implemented the Transfer of Class Agreement (TOCA), whereby no member would accept a ship that had not carried out improvements demanded by its previous class society. Currently, more than 50 organizations worldwide describe their activities as including marine classification, some of which are listed below. Twelve of these are members of

310-599: The International Association of Classification Societies . The largest are DNV , the American Bureau of Shipping , Nippon Kaiji Kyokai (ClassNK) and Lloyd's Register . Classification societies employ naval architects , ship surveyors , material engineers , piping engineers, mechanical engineers and electrical engineers , often located at ports and office buildings around the world. Marine vessels and structures are classified according to

341-614: The Group President and CEO of DNV since August 1, 2015, succeeding Henrik O. Madsen . DNV's history dates from 1864, when Det Norske Veritas was established in Norway to head the technical inspection and evaluation of Norwegian merchant vessels . Germanischer Lloyd was founded in Hamburg in 1867 by a group of 600 ship owners, ship builders and insurers. The company celebrated its 150th anniversary in 2014. On 20 December 2012,

372-467: The Register Society published the first Rules for the survey and classification of vessels, and changed its name to Lloyds Register of Shipping. A full-time bureaucracy of surveyors (inspectors) and support personnel was put in place. Similar developments were taking place in the other major maritime nations. The adoption of common rules for ship construction by Norwegian insurance societies in

403-432: The availability of preferred mortgages on documented vessels. Vessels that operate internationally or cross international borders are required to be registered. Some jurisdictions also require vessels that only operate in territorial waters to register on their national register, and some forbid foreign-flagged vessels from trading between ports within the country (a practice known as cabotage ). The country of registration

434-408: The classification profession evolved, the practice of assigning different classifications has been superseded, with some exceptions. Today a ship either meets the relevant class society's rules or it does not. As a consequence, it is either 'in' or 'out' of 'class'. Classification societies do not issue statements or certifications that a vessel is 'fit to sail' or 'unfit to sail', merely that the vessel

465-400: The company has about 15,000 employees and 350 offices operating in more than 100 countries and provides services for several industries. In 2013, Det Norske Veritas (Norway) and Germanischer Lloyd (Germany), two prominent organizations in the industry, merged to form DNV GL. The company later simplified its name to DNV in 2021, while maintaining the organizational structure that resulted from

496-410: The condition of the ship's hull and equipment. At that time, an attempt was made to classify the condition of each ship on an annual basis. The condition of the hull was classified A, E, I, O or U, according to the state of its construction and its adjudged continuing soundness (or lack thereof). Equipment was G, M, or B: simply, good, middling or bad. In time, G, M and B were replaced by 1, 2 and 3, which

527-431: The larger societies also conduct research at their own research facilities in order to improve the effectiveness of their rules and to investigate the safety of new innovations in shipbuilding. Ship registration Ship registration is the process by which a ship is documented and given the nationality of the country to which the ship has been documented. The nationality allows a ship to travel internationally as it

558-530: The late 1850s led to the establishment of Det Norske Veritas (DNV) in 1864. RINA was founded in Genoa, Italy in 1861 under the name Registro Italiano Navale , to meet the needs of Italian maritime operators. Germanischer Lloyd (GL) was formed in 1867 and Nippon Kaiji Kyokai (ClassNK) in 1899. The Russian Maritime Register of Shipping (RS) was an early offshoot of the River Register of 1913. As

589-539: The merger. DNV provides services for 13,175 vessels and mobile offshore units (MOUs), amounting to 265.4 million gross tonnes , which represents a global market share of 21%. 65% of the world's offshore pipelines are designed and installed to DNV's technical standards . Prior to the merger, both DNV and GL had independently acquired several companies in different sectors, such as Hélimax Energy (Canada), Garrad Hassan (UK), Windtest (Germany) and KEMA (Netherlands). DNV also invests in research. Remi Eriksen has been

620-482: The only classification society to do so. Classification surveyors inspect ships to make sure that the ship, its components and machinery are built and maintained according to the standards required for their class. In the second half of the 18th century, London merchants, shipowners, and captains often gathered at Edward Lloyd's coffee house to gossip and make deals including sharing the risks and rewards of individual voyages. This became known as underwriting after

651-538: The practice of signing one's name to the bottom of a document pledging to make good a portion of the losses if the ship didn't make it in return for a portion of the profits. It did not take long to realize that the underwriters needed a way of assessing the quality of the ships that they were being asked to insure. In 1760, the Register Society was formed — the first classification society and the one which would subsequently become Lloyd's Register — to publish an annual register of ships. This publication attempted to classify

682-488: The process of construction and commissioning, and periodically survey vessels to ensure that they continue to meet the rules. Classification societies are also responsible for classing oil platforms , other offshore structures, and submarines . This survey process covers diesel engines, important shipboard pumps and other vital machinery. Since the 1950s, the USSR (now Russian) Register of Shipping has classified nuclear ships,

713-672: The safety, fitness for purpose, or seaworthiness of the ship, but is a verification only that the vessel is in compliance with the classification standards of the society issuing the classification certificate. Classification societies also issue International Load Line Certificates in accordance with the legislation of participating states giving effect to the International Convention on Load Lines (CLL 66/88). Classification societies set technical rules based on experience and research, confirm that designs and calculations meet these rules, survey ships and structures during

744-488: The seas has been important. Originally meant to control ships carrying cargo in European seafaring countries, it was used to make sure ships were being built in the local country, with crews predominantly of the local country. Since then, ship registration has been used to document ships for ownership. Documentation provides definite evidence of nationality for international purposes and provides financing opportunities with

775-581: The ship is known as its registry. Registries may be governmental or private agencies. In some cases, such as the United States' Alternative Compliance Program, the registry can assign a third party to administer inspections. A register that is open only to ships of its own nation is known as a traditional or national register . Registers that are open to foreign-owned ships are known as open registries and are sometimes called flags of convenience . Ship registration has been done since business on

806-440: The soundness of their structure and design for the purpose of the vessel. The classification rules are designed to ensure an acceptable degree of stability, safety, environmental impact, etc. In particular, classification societies may be authorised to inspect ships, oil rigs, submarines, and other marine structures and issue certificates on behalf of the flag state . As well as providing classification and certification services,

837-739: The two companies announced the merger, which was approved by competition authorities in South Korea , the US, the EU, and China, thus allowing the merger contract between DNV and GL to be signed on 12 September 2013. The independent Det Norske Veritas Foundation owned 63.5% of DNV GL shares and 36.5% of Mayfair Vermögensverwaltung until December 2017, when Mayfair sold its shares to the Det Norske Veritas Foundation. DNV GL changed its name to DNV on 1 March 2021. In September 2023, it

868-466: The types of vessels that it will accept for registration. The Liberian Registry, for example, registers seagoing vessels of more than 500 net tons that conduct foreign trade. Vessels over the age of 20 require a waiver as well as the vessel's classification society being willing to issue statutory certificates to the vessel. Vessels 15 years or older must have a Status Report of the vessel's Special Survey to be reviewed by Marine Safety. Registries charge

899-771: Was announced that DNV had acquired the US-headquartered SaaS company, ANB Systems. The company provides energy programme services to utility and regulatory body customers. Every year, DNV invests heavily in research and development, amounting to 5% of its total revenue. Many of the DNV standards have often been used as the basis for international standards. As of 2021, the main research programs include maritime, power and renewables, oil and gas, precision medicine, digital assurance, ocean space, artificial intelligence and energy transition . DNV publishes its independent Energy Transition Outlook annually. The fifth edition

930-637: Was founded in Antwerp in 1828, moving to Paris in 1832. Lloyd's Register reconstituted in 1834 to become 'Lloyd's Register of British and Foreign Shipping'. Where previously surveys had been undertaken by retired sea captains, from this time surveyors started to be employed and Lloyd's Register formed a General Committee for the running of the Society and for the Rules regarding ship construction and maintenance, which began to be published from this time. In 1834,

961-743: Was repeated in Article 91 of the United Nations Convention on the Law of the Sea of 1982 (UNCLOS), which came into effect in 1994. That Convention has 167 parties. In 1986, the United Nations Conference on Trade and Development attempted to solidify the genuine link concept in the United Nations Convention on Conditions for Registration of Ships . The Convention on Conditions for Registration of Ships would require that
