A storage tank with a flat roof that floats on the surface of the oil thus reducing evaporation to the minimum. The roof rests on a series of pontoons whose buoyancy supports the roof proper; a floater. These are used for storage of high volatile components such as gasoline, naphtha and benzene.
An FPSO system is an offshore production facility that is typically ship-shaped and stores crude oil in tanks located in the hull of the vessel. The crude oil is periodically offloaded to shuttle tankers or ocean-going barges for transport to shore. FPSO’s may be used as production facilities to develop marginal oil fields or fields in deepwater areas remote from the existing pipeline infrastructure.
It is a moored or dynamic positioned floating structure.
Used where it is not possible or efficient to lay a pipeline to the shore. The production platform will transfer the oil or gas to the FSO where it will be stored until a tanker arrives and connects to the FSO to offload it. In addition in times of surplus of LNG tankers these can be used as floating storage if required.
These are LNG liquefaction facilities that are constructed offshore rather than onshore.
Rigs that stay afloat offshore and are reliable in rough seas. They are most frequently used for drilling new wells (Wildcat Wells)
