Most common Kinds of offshore Platforms

Offshore equipment is a vital piece of equipment for the production of oil and gas collected from under the seabed. Here is a look at the most commonly used offshore platforms that are used around the world.

Shallow water Complex: A Shallow water platform is used when the depth of the water above the oilfield is about one hundred and fifty meters (500ft). These complexes have legs that reach the bottom of the sea floor. On the surface, the facility is also fitted with Blowout preventers that are remote controlled or operated manually. A blowout preventer is installed to prevent any uncontrollable flow of oil or gas from the oilfield. The oil wells that are found beneath shallow waters mostly are sources of natural gas.

Gravity Based structure: A gravity based structure is mainly built for sea beds that are extremely hard. This type of offshore platforms consist of a concrete base on the sea floor that is made really heavy and would hold the entire facility from drifting or moving.

Compliant Towers: Compliant towers are suited for water depths form 450 to 900 meters. Compliant towers are fixed oil rigs. They have a tower that extends from the platform to the seabed. Compliant towers are flexible and ideal for use where wind speeds are higher as they can absorb the pressure that is put on the rig by the wind and sea.

Floating Productions:                          

A Floating Production, Storage and Offloading (FPSO), is a vessel designed for the production and processing and for the storage of oil. These vessels are useful at locations with deep water and are far from the shore. Floating vessels removes the necessity to install pipelines to an onshore terminal.     

A Tension Leg Platform (TLP) is another floating production system is popular for the stability it has to offer. The tension legs or tendons reach from the hull to the sea bed secure the facility. The tendons do not allow any upward movements this in turn does not allow the facility to move up and down making it stable even during hurricanes.
