All you need to know about subsea pipelines

Subsea pipes play an important role in our day-to-day lives as well as in major deals between countries or companies. As discussed below, many subsea pipes have been laid to transport crucial commodities.

What are subsea pipeline and what are they capable of transporting ?

Any pipeline system laid in water is a subsea pipe. Any pipeline, i.e. natural gas and crude oil are all examples of subsea pipelines. This term is commonly used to describe gas and oil pipeline systems that are submerged within the sea or river. Depending on the material being transported, subsea pipeline systems can have different designs and specifications. These pipelines transport oil, gas, and hazardous materials over oceans.


We use pipelines all the time, they are essential in our everyday lives.


An extra conveyor is mounted on the pipe-laying vessel. After receiving the welded pipes they are checked for defects and an anticorrosion product is applied to each joint. The tubes move towards the fore. The pipes are immersed in the water at an angle using a stinger. Finally, they are lowered into the seabed. Three types of installation are possible: S-lay, Tow-In and J-line. The collapsible, plastic pipe system is currently the best-performing pipeline technology. They can be attached to the seabed, and can be flexible: This pipeline can cut off flow to allow deflation to reduce damage risks in extreme circumstances. The pressure of the pipes can be adjusted using offshore or onshore terminals.
