ABSTRACT:
The present invention contemplates a system comprising a pumping module coupled to an intermediate flow inlet (IFI) wherein said IFI is coupled to a base structure disposed on the flow line that routes production from one or more oil wells, allowing for the quick and easy installation or recovery of a subsea pumping module by cable from an inexpensive vessel. The present invention also allows for the hydraulic isolation of the subsea pumping module by means of on-off valves on the IFI whereby the pumping module can be easily installed or removed without causing underwater oil spills. Sealing of the connection is of the metal-metal type. It is also possible to pass a pig through the present system for clearing the flow lines.
