An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate. It consists of an open- topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid. The roof rises and falls with the liquid level in the tank. [1]
Cylindrical fuel storage tank with fixed roof and internal floating roof. Capacity approx 2,000,000 litres. The word "tank" originally meant "artificial lake" and came from India, perhaps via Portuguese tanque. It may have some connection with: Some Indian language words similar to "tak" or "tank" and meaning "reservoir for water".
The storage tanks at an oil terminal may include fixed roof tanks, internal floating roof tanks [10] and external floating roof tanks. [1] Floating roof tanks are generally used for more volatile products to reduce evaporation loss. Fixed roof tanks have a vapor space above the product, which breathes in or out as the product is removed or the ...
Fixed roof tank. A fixed roof tank is a type of storage tank, used to store liquids, consisting of a cone- or dome-shaped roof that is permanently affixed to a cylindrical shell. Newer storage tanks are typically fully welded and designed to be both liquid- and vapor-tight. Older tanks, however, are often riveted or bolted, and are not vapor tight.
A floating production storage and offloading (FPSO) unit is a floating vessel used by the offshore oil and gas industry for the production and processing of hydrocarbons, and for the storage of oil. An FPSO vessel is designed to receive hydrocarbons produced by itself or from nearby platforms or subsea template, process them, and store oil ...
Fibre-reinforced plastic tanks and vessels. Fixed roof tank. Flexible tank. Fuel bladder.
Offshore concrete structure. Offshore concrete structures, or concrete offshore structures, are structures built from reinforced concrete for use in the offshore marine environment. They serve the same purpose as their steel counterparts in oil and gas production and storage. The first concrete oil platform was installed in the North Sea in the ...
Spar (platform) A spar is a marine structure, used for floating oil/gas platforms. Named after navigation channel Spar buoys, spar platforms were developed as an extreme deepwater alternative to conventional platforms. [1] The deep draft design of spars makes them less affected by wind, wave, and currents and allows for both dry tree and subsea ...
