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]
Some storage tanks need a floating roof in addition to or in lieu of the fixed roof and structure. This floating roof rises and falls with the liquid level inside the tank, thereby decreasing the vapour space above the liquid level. Floating roofs are considered a safety requirement as well as a pollution prevention measure for many industries ...
The external tank's orange color, which would become iconic of the Space Shuttle program, is the color of the spray-on foam insulation. The first two tanks, used for STS-1 and STS-2 , were painted white to protect the tanks from ultraviolet light during the extended time that the shuttle spent on the launch pad prior to launch. [ 7 ]
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 ...
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 ...
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 ...
Fibre-reinforced plastic tanks and vessels. FRP (Fibreglass Reinforced Plastics, also known as GRP, or Glass Reinforced Plastics) is a modern composite material of construction for chemical plant, pulp and paper mill, and food and pharmaceutical equipment like tanks and vessels. Chemical equipment that range in size from less than a metre to 20 ...
Ship stability. Ship 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.
