Subsea pumping system

摘要

A technique is provided for pumping fluid in subsea applications. A self-contained pumping module is created by mounting a pumping unit on a skid that can be lowered to a sea floor. The skid comprises a support structure designed to hold the pumping unit in a desired orientation, such as an inclined orientation with respect to a base of the skid. The self-contained nature of the pumping module facilitates deployment to a sea floor/retrieval from the sea floor to enable use of the pumping module in a variety of subsea applications with reduced complexity and cost.

1. A method for pumping fluid at a subsea location, comprising:
sliding a skid along a sea floor to a selected location, the skid including support structures having a plurality of brackets for releasably attaching multiple pump modules to the skid, each pump module attachable undersea and detachable undersea for module replacement; providing onboard control of multiple different configurations of a flow path for pumped fluid or gas lift via a control module mounted on the skid; receiving sensor inputs from multiple flow sensors and multiple valve state sensors of the multiple pump modules; configuring the multiple pump modules via the control module to create a flow path at the subsea location from a selection of multiple different configurations of a flow path for pumped fluid or gas lift; and maintaining a fluid output of the multiple pump modules via the configuring during attachment and detachment of one or more of the multiple pump modules for replacement.
