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 ...
External floating roof tank. 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 ...
Oil tanker. 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]
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 Ekofisk oil field in 1973 by ...
Steam-assisted gravity drainage ( SAGD; "Sag-D") is an enhanced oil recovery technology for producing heavy crude oil and bitumen. It is an advanced form of steam stimulation in which a pair of horizontal wells are drilled into the oil reservoir, one a few metres above the other. High pressure steam is continuously injected into the upper ...
Oil production plant. An oil production plant is a facility which processes production fluids from oil wells in order to separate out key components and prepare them for export. Typical oil well production fluids are a mixture of oil, gas and produced water. An oil production plant is distinct from an oil depot, which does not have processing ...
natural water displacing oil downward into the well; expansion of the associated petroleum gas at the top of the reservoir; expansion of the associated gas initially dissolved in the crude oil; gravity drainage resulting from the movement of oil within the reservoir from the upper to the lower parts where well extraction is located.
Oil and natural gas. Oil platform Mittelplate in the N. An oil platform (also called an oil rig, offshore platform, oil production platform, etc.) is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed.
