Submarine pipeline - Wikipedia

A submarine pipeline (also known as marine, subsea or offshore pipeline) is a pipeline that is laid on the seabed or below it inside a trench. In some cases, the pipeline is mostly on-land but in places it crosses water expanses, such as small seas, straits and rivers. Submarine pipelines are used primarily to carry oil or gas, but transportation of water is also important.

Nov 01, 2019  In this study, based on the hydrodynamics, heat transfer, and hydrate behaviors in the pipeline, a new model was established to forecast the dynamic deposition of hydrates in gas pipelines where the flow pattern is the water-saturated gas flow, which can improve the gas transportation efficiency and safety in subsea and cold regions.
