Classification society |
worldwide non-governmental, experienced and reputable organizations or groups of professionals, ship surveyors and representatives of offices that promote the safety and protection of the environment of vessels and offshore structures. To do so, such societies set technical rules, confirm that designs and calculations meet these rules, survey vessels and structures during the process of construction and commissioning, and periodically survey vessels to ensure that they continue to meet the rules |
Containership |
cargo ship that carry all of its load in truck-size containers, in a technique called containerization |

DNV GL |
Det Norse Veritas is a classification society founded in 1864 and originally a Norwegian-based organization that inspected and evaluated the technical condition of merchant vessels there. Since then, the core competencies have expanded to cover the identification, assessment and advisement on managing risk in a variety of industries (including maritime vessels); Germanisher Lloyd is a classification society founded in 1867, which is a German-based organization that serves a wide range of industries in both the maritime and energy sectors. DNV and GL signed an agreement to merge in December 2012. The new entity will be called DNV GL Group. |

Energy Efficiency
Design Index or EEDI |
an index quantifying the amount of carbon dioxide that a vessel emits in relation to the goods transported |
FPSO |

the United Nations agency for maritime safety and the prevention of marine pollution by ships established in 1948 |
Jack-up |
a type of mobile platform that is able to stand still on the sea floor, resting on a number of supporting legs. The most popular designs use three independent legs, although some jack-ups have four legs or more. on “mat-type” jack-ups the legs are connected to a submerged hull |
Keel |
a large beam around which the hull of a ship is built. The keel runs in the middle of the ship, from the bow to the stern, and serves as the foundation or spine of the structure, providing the major source of structural strength of the hull. The keel is generally the first part of a ship’s hull to be constructed |
LNG |
liquefied natural gas |

Lloyd’s Register Society, a classification society and independent risk management organization founded in 1760 in the United Kingdom, is a non-profit organization that provides risk assessment and mitigation services and management systems certification |
Panamax |
ships classified as Panamax are of the maximum dimensions that will fit through the locks of the Panama Canal, each of which is 1,000 feet long by 110 feet wide and 85 feet deep. Accordingly, a Panamax ship will usually have dimension of approximately 965 feet long (294.0 meters), 106 feet wide (32.3 meters) and a draft of 39.5 feet (12.0 meters) |
Suezmax |
ships of between 120,000 DWT and 200,000 DWT, with dimensions allowing it to transit the Suez Canal fully loaded |
TEU |
twenty-foot equivalent unit, an inexact unit of cargo capacity often used to describe the capacity of containerships and container terminals. it is based on the volume of a 20-foot-long (film) intermodal container, a standard-sized metal box |
