A system for installation of a subsea module of great length by means of a vessel, using a cable for its installation and/or retrieval, and methods applied therein. The system allows transporting the subsea module on the vessel to a location in the sea and descending the subsea module into the sea at a vertical position for installation on the seabed.

System for installation and replacement of a subsea module and method applied thereby

A system for the direct vertical connection between contiguous sub sea equipment is described, having one or more hydrocarbon flow and/or control interconnection between same, so as to dispense with the use of connecting jumpers. One mode of said system comprises a PuABvertically and directly connected to a PrAB. Equipment is directly fixed through the PuAB connectorwith a PrAB-production mandrel, said mandrel being fitted with a funnel guide. PuABis fitted with a funnelso as to guide the drilling of a cased boreholein the marine soil, close to well. Once the cased boreholeis ready, PuABwill be locked to the casing of said boreholeby means of a locking system, so as to complete the mechanical and hydraulic connection between the two devices, PuAB and PrAB or HWCT. Two modes of the method for installation of said system are also described.

System for direct vertical connection between contiguous subsea equipment and method of installation of said connection

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.
