Submarine pipeline

A submarine pipeline (also known as marine, subsea or offshore pipeline) is a <a href="/facts/Pipeline_transport/gEmKcFhD">pipeline</a> that is laid on the <a href="/facts/Seabed/VvxuEWJu">seabed</a> 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. A distinction is sometimes made between a flowline and a pipeline. The former is an intrafield pipeline, in the sense that it is used to connect subsea <a href="/facts/Wellhead/U4R8dSx9">wellheads</a>, manifolds and the <a href="/facts/Oil_platform/n1eKvqpy">platform</a> within a particular development field. The latter, sometimes referred to as an export pipeline, is used to bring the resource to shore. Sizeable pipeline construction projects need to take into account many factors, such as the offshore ecology, geohazards and environmental loading – they are often undertaken by multidisciplinary, international teams.
