Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
A major component of tanker architecture is the design of the hull or outer structure. A tanker with a single outer shell between the product and the ocean is said to be single-hulled.[4] Most newer tankers are double-hulled, with an extra space between the hull and the storage tanks. [4] Hybrid designs such as double-bottom and double-sided ...
Rear house, full hull, midships pipeline. An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. [1] Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. [1]
A bulk carrier or bulker is a merchant ship specially designed to transport unpackaged bulk cargo —such as grain, coal, ore, steel coils, and cement—in its cargo holds. Since the first specialized bulk carrier was built in 1852, economic forces have led to increased size and sophistication of these ships. Today's bulk carriers are specially ...
Ballast. Cross section of a vessel with a single ballast tank at the bottom. Ballast is dense material used as a weight to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or ...
Surrounding the tanks is a combination of ballast tanks, cofferdams and voids; in effect, this gives the vessel a double-hull type design. LNG carriers, like aircraft carriers, are among the most difficult vessels to build, taking as long as 30 months. [24] Inside each tank there are typically three submerged pumps.
The vessel's owner said its water ballast tank, which helps it stay balanced, had suffered a breach in the incident. Mark Clark, a spokesman for the ship's owner Mitsui OSK, said it would probably ...
The modern oil tanker. The modern oil tanker was developed in the period from 1877 to 1885. [9] In 1876, Ludvig and Robert Nobel, brothers of Alfred Nobel, founded Branobel (short for Brothers Nobel) in Baku, Azerbaijan. It was, during the late 19th century, one of the largest oil companies in the world.
