ShipbuildingShipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking.
Suezmax"Suezmax" is a naval architecture term for the largest ship measurements capable of transiting the Suez Canal in a laden condition, and is almost exclusively used in reference to tankers. The limiting factors are beam, draft, height (because of the Suez Canal Bridge), and length (even though the canal has no locks). The current channel depth of the canal allows for a maximum of of draft, meaning that a few fully laden supertankers are too deep to fit through, and either have to unload part of their cargo to other ships ("transhipment") or to a pipeline terminal before passing through, or alternatively avoid the Suez Canal and travel around Cape Agulhas instead.
Ship model basinA ship model basin is a basin or tank used to carry out hydrodynamic tests with ship models, for the purpose of designing a new (full sized) ship, or refining the design of a ship to improve the ship's performance at sea. It can also refer to the organization (often a company) that owns and operates such a facility. An engineering firm acts as a contractor to the relevant shipyards, and provides hydrodynamic model tests and numerical calculations to support the design and development of ships and offshore structures.
Ship stabilityShip stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged. Stability calculations focus on centers of gravity, centers of buoyancy, the metacenters of vessels, and on how these interact. Ship stability, as it pertains to naval architecture, has been taken into account for hundreds of years. Historically, ship stability calculations relied on rule of thumb calculations, often tied to a specific system of measurement.
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.
TitanicRMS Titanic was a British passenger liner, operated by the White Star Line, that sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England to New York City, United States. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making it the deadliest sinking of a single ship up to that time. It remains the deadliest peacetime sinking of an ocean liner or cruise ship.
Bow (watercraft)The bow (baʊ) is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function.
Remotely operated underwater vehicleA remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform tasks such as valve operations, hydraulic functions and other general tasks within the subsea oil and gas industry. ROVs can also carry tooling packages for undertaking specific tasks such as pull-in and connection of flexible flowlines and umbilicals, and component replacement. This meaning is different from remote control vehicles operating on land or in the air.
HandymaxHandymax and Supramax are naval architecture terms for the larger bulk carriers in the Handysize class. Handysize class consists of Supramax (50,000 to 60,000 DWT), Handymax (40,000 to 50,000 DWT), and Handy (
SS Great EasternSS Great Eastern was an iron sail-powered, paddle wheel and screw-propelled steamship designed by Isambard Kingdom Brunel, and built by John Scott Russell & Co. at Millwall Iron Works on the River Thames, London, England. She was the largest ship ever built at the time of her 1858 launch, and had the capacity to carry 4,000 passengers from England to Australia without refuelling. Her length of was surpassed only in 1899 by the 17,274-gross-ton , her gross tonnage of 18,915 was only surpassed in 1901 by the 20,904-gross-ton and her 4,000-passenger capacity was surpassed in 1913 by the 4,234-passenger .
