A subsea pipeline is a type of pipeline that is laid on or beneath the seabed to transport oil, gas, or other fluids. These pipelines are essential for connecting offshore drilling platforms to onshore facilities, allowing for the efficient movement of resources extracted from beneath the ocean floor. Constructed from durable materials, subsea pipelines are designed to withstand harsh underwater conditions, including high pressure and corrosive environments. They are often monitored and maintained using specialized equipment and remotely operated vehicles (ROVs) to ensure safety and reliability in transporting valuable resources like crude oil and natural gas.
