How Steel Pipe is Used in Offshore Drilling
Generally, steel is a very versatile material and used in almost any field. It’s strong, durable, malleable and relatively cheaper than the alternatives. Steel pipes are no different. They are used for sewers, industrial projects, and commercial structures. One of those uses is in offshore drilling.
Steel Pipes Are Often Used in Offshore Drilling
Offshore drilling is usually done to extract petroleum in rock formations underneath the seabed. These rigs can operate in deep water, up to 9,800 feet, and in shallow water, at around 4,900 feet. To make sure that the process goes smoothly, companies use reliable materials that will make it easier for them to penetrate the surface and carry the petroleum from it was taken to barges or other facilities.
Since this a very sore topic, especially with environmental concerns growing more and more, it’s imperative that practices employed and materials used by oil drilling companies are top notch. It avoids the possibility of accidents, like oil spills, that could affect human and marine life.
As you may have guessed, there are a lot of variations of steel pipes used for projects like this, here are a few:
Top tensioned and steel catenary risers
Risers are pipes that hook up your rig or offshore facility to your sub-sea system. This is a pipe that can be used either for production (like injection and exporting) or drilling (including completion and workover).
Because of its dynamic load, it has to be strong to be able to withstand the conditions. It comes in different kinds like the Steel Catenary Risers for production and Drilling Risers for drilling.
Flow lines/ Export line
These are also known as pipelines because they transport both the processed and unprocessed oil and gas fluids back to shore. These pipes have to be able to endure deep sea environments where pressure and corrosion affect the material really quickly.
Bend pipes need to flexible and customizable to certain angles other than 45º and 90º. This is one of the reasons why steel is perfect for bends. It’s extremely malleable, without compromising its strength or durability.
Bends are made with advanced hot induction machines that allow manufacturers to control the bending process, so the results are specific to the needs of the buyers.
Coiled line pipe
This is a great alternative to the 12-meter line pipe because it’s a lot easier to install and also cheaper. It even has a better coating and allows the oil or gas fluids to flow easier.
