Pipelines

Pipeline information and database. The Subsea Oil and Gas Directory is much more than only a list of subsea focused businesses and companies. It also contain a massive amount of information on upstream products, projects, drilling rigs and pipelines.

Pipelines or flowlines are used to transport liquids or gases, often water or petroleum. This transport is cheaper than tankers when large quantities are to be transported and is particularly profitable for natural gas.

Subsea Pipelines

Flowlines can be laid at water depths greater than 300 meters, and the diameter of the pipe can often be up to 1.5 meters. Pipe diameters of 16–42 inches (40–105 cm) are common on subsea pipelines.

The most common joining method is to weld the pipes together on a pipelay vessel. In shallow water and over smaller distances, the pipes can also be pulled out ashore as new pipe lengths are welded (bottom drawing). The pipeline can also be laid by the coil method, where the pipes are first welded together on land and wound up on a large drum.

Search for pipeline in our database and you will find useful information such as the name and operator, the start and end country, the length. Also, there is information on the size and medium.
