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]
An oil terminal (also called a tank farm, tankfarm, oil installation or oil depot) is an industrial facility for the storage of oil, petroleum and petrochemical products, and from which these products are transported to end users or other storage facilities. [1]
An oil tanker's inert gas system is one of the most important parts of its design. [18] Fuel oil itself is very difficult to ignite, however its hydrocarbon vapors are explosive when mixed with air in certain concentrations. [19] The purpose of the system is to create an atmosphere inside tanks in which the hydrocarbon oil vapors cannot burn. [18]
Oil storage tanks at Fawley. Fawley refinery processes around 270,000 barrels (43,000 m 3) of crude oil a day and provides 20 per cent of the UK's refinery capacity. [1] Crude oil is transported by sea in tankers to the refinery's one-mile-long (1,600 m) marine terminal, which handles around 2,000 ship movements and 22 million tonnes of crude oil and other products every year.

Standard fuel bladder tanks sizes range from 100-US-gallon (380 L) to 200,000-US-gallon (760,000 L) capacities and larger. Custom fuel storage bladders and cells are available, although at sizes exceeding 50,000 US gallons (190,000 L) there is an increased spill risk.
Depending on the size of the pump, it generally produces 5 to 40 litres (1 to 9 imp gal; 1.5 to 10.5 US gal) of liquid at each stroke. Often this is an emulsion of crude oil and water. Pump size is also determined by the depth and weight of the oil to remove, with deeper extraction requiring more power to move the increased weight of the ...
Their main mass is represented by the storage tank (ca. 100m diameter and 56m high, consisting of 19 cylindrical compartments with 20m diameter). Three of the cells are extended into shafts tapering off at the surface and carrying a steel deck. The tanks serve as storage of crude oil in the operation phase.
The majority of tanks were situated above ground in an elevated position. This meant the oil could flow into each house under the influence of gravity. Other tanks were situated underground and were equipped with an electric pump, usually feeding oil to a small 'header' tank, again in an elevated position, to allow gravity to then distribute ...
