Load Line (vessel)
The load line, also known as Plimsoll line, indicates the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. The load line is a waterline that corresponds to the maximum draft of the ship, thus yet another name, load waterline. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater, with a similar lessening effect upon buoyancy. The rules for international load lines are defined by the International Convention on Load Lines from 1966. For inland water transport regional, national or local rules apply. Load lines are indicated by special markings on the hull. The marking for the main load line, the summer load line, is called load line mark or Plimsoll mark (positioned amidships), the marks for oth ...

Buoyancy
Buoyancy (), or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the submerged volume of the object, i.e. the displaced fluid. For this reason, an object whose average density is greater than that of the fluid in which it is submerged tends to sink. If the object is less dense than the liquid, the force can keep the object afloat. This can occur only in a no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lloyd's Register
Lloyd's Register Group Limited (LR) is a technical and professional services organisation and a maritime classification society, wholly owned by the Lloyd’s Register Foundation, a UK charity dedicated to research and education in science and engineering. The organisation dates to 1760. Its stated aims are to enhance the safety of life, property, and the environment, by helping its clients (including by validation, certification, and accreditation) to improve the safety and performance of complex projects, supply chains and critical infrastructure. In July 2012, the organisation converted from an industrial and provident society to a company limited by shares, named Lloyd’s Register Group Limited, with the new Lloyd’s Register Foundation as the sole shareholder. At the same time the organisation gave to the Foundation a substantial bond and equity portfolio to assist it with its charitable purposes. It will benefit from continued funding from the group’s operating arm, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Registro Italiano Navale
RINA is a private, multinational company headquartered in Genoa, Italy. It was founded in 1861 under the name Registro Italiano Navale (''Italian Naval Register''). That same year, following the enforcement of a 1994 European Council directive regarding the inspection, survey and certification of ships that liberalized the ship classification market, the Registro Italiano Navale transferred all operational activities to RINA S.p.A., making it the sole, and later, majority shareholder. Until 1999, RINA worked almost exclusively as a ship classification company, and has since included operations in the following sectors: Energy and Mobility, Marine, Certification, Industry and Real Estate and Infrastructure. The company has also expanded its services in the fields of testing, inspection and certification and engineering consultancy.

Nippon Kaiji Kyokai
is a ship classification society. It is also known by the brand name “ClassNK” or often in the industry as just “NK”. ClassNK is a non-profitable non-governmental organization dedicated to ensure the safety of life and property at sea, and the prevention of pollution of the marine environment. The principal work of the Society's expert technical staff is to undertake surveys to ensure that the rules which it has developed, are applied to both newly built and existing ships in order to ensuring the safety of these vessels. The rules cover not only hull structures, but also safety equipment, cargo handling gear, engines, machinery, and electrical and electronic systems among others. By the end of December 2007, the Society had 6793 ships totaling 152.22 million gross tons under class. This figure represents approximately 20 percent of the world merchant fleet currently under class. Although based in Japan, ClassNK has worldwide representation through a network of exclu ...
