Intermediate booster pumping station

摘要

An intermediate booster station is used to pump well fluid along a sub-sea pipeline to an onshore location. The intermediate booster station comprises a watertight base 1, from which protrudes a telescopic shaft 2. The shaft 2 extends above sea level and has a wind turbine 3 attached at the top. A water turbine 4 may also be attached as shown. The base I is connected to a sub-sea pipeline 5 routed from a wellhead 6 to an onshore location 7. A booster pump 8 is located in the base 1. The booster station is located to receive the well fluid under well pressure and the booster pump then pumps the well fluid to the shore. The turbine(s) 3, (4) provide(s) power to electricity generating equipment housed in or on the structure which in turn powers the booster pump. In the event of the turbines not producing enough power to operate the booster pump then excess well fluid can be stored in a storage facility until normal operation can resume.
