What is an offshore TLP?
A tension-leg platform (TLP) or extended tension leg platform (ETLP) is a vertically moored floating structure normally used for the offshore production of oil or gas, and is particularly suited for water depths greater than 300 metres (about 1000 ft) and less than 1500 metres (about 4900 ft).
What is Platform in oil and gas?
An oil platform, offshore platform, or offshore drilling rig is a large structure with facilities for well drilling to explore, extract, store, and process petroleum and natural gas that lies in rock formations beneath the seabed.
What is offshore fabrication?
Offshore structure components are fabricated and assembled onshore, transported to an offshore site and then installed. Thus, construction methods, material specifications and the acceptable construction tolerances applicable to offshore structures substantially differ from those applicable to onshore structures.
What is a fixed offshore platform?
A fixed platform is a type of offshore platform used for the extraction of petroleum or gas. These platforms are built on concrete and/or steel legs anchored directly onto the seabed, supporting a deck with space for drilling rigs, production facilities and crew quarters.
Which of the following is the largest offshore platform in use?
The Berkut Platform in the Sea of Okhotsk on the Russian Pacific Coast. Developed by Russian oil giant Rosneft, ExxonMobil, and other partners, the Berkut platform is the largest in the world, weighing a gargantuan 200,000 tons.
How do offshore oil rigs float?
These rigs float and can be attached to the ocean bottom using traditional mooring and anchoring systems or they maintain their position by using thrusters to counteract winds, waves and currents.
What is the meaning of offshore engineering?
Offshore Engineering is the engineering discipline that deals with the design and construction of structures intended to work in a stationary position in the ocean environment. The majority of offshore structures are used in the Oil and Gas industry and for Offshore Wind Turbines.
What is the largest offshore platform in the world?
The Hibernia platform in Canada is the world’s largest (in terms of weight) offshore platform, located on the Jeanne D’Arc Basin, in the Atlantic Ocean off the coast of Newfoundland.
What are the different types of offshore platforms for oil drilling?
Larger lake- and sea-based offshore platforms and drilling rig for oil. 1, 2) conventional fixed platforms; 3) compliant tower; 4, 5) vertically moored tension leg and mini-tension leg platform; 6) spar; 7, 8) semi-submersibles; 9) floating production, storage, and offloading facility; 10) sub-sea completion and tie-back to host facility.
What are the different types of structures used in marine platforms?
Various types of structure are used: steel jacket, concrete caisson, floating steel, and even floating concrete. Steel jackets are structural sections made of tubular steel members, and are usually piled into the seabed. To see more details regarding Design, construction and installation of such platforms refer to: and.
What are the negative effects of offshore oil production?
Effects on the environment. Offshore oil production involves environmental risks, most notably oil spills from oil tankers or pipelines transporting oil from the platform to onshore facilities, and from leaks and accidents on the platform.
