Abstract: Systems and methods are described that allow for pressure boosting of liquids in a hydrocarbon gas-liquid separator disposed at seabed. The separator can include an upper section and a lower section, which are fluidly coupled via at least one conduit. A first pump can be coupled to the separator that is configured to boost the pressure level of liquid in the lower section while the separator is disposed at seabed.

Abstract: A method for monitoring and maintaining a pipeline is shown which includes installing a monitoring system for measuring at least one parameter of interest, the monitoring system including various monitoring sensors placed at selected locations along the pipeline. A series of measurements are taken using the monitoring sensors in real time. The measurements are analyzed to identify anomalous conditions existing in the pipeline being monitored. An autoadaptive corrective action is implemented based upon the real time measurement of the parameter of interest.
