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 PuAB 221 vertically and directly connected to a PrAB 104. Equipment is directly fixed through the PuAB connector 251 with a PrAB 104-production mandrel 107, said mandrel being fitted with a funnel guide 112. PuAB 221 is fitted with a funnel 224 so as to guide the drilling of a cased borehole 220 in the marine soil 101, close to well 111. Once the cased borehole 220 is ready, PuAB 221 will be locked to the casing of said borehole 220 by 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.
A system for direct vertical connection between at least two subsea contiguous equipment utilized in the production of hydrocarbon fluids, with hydrocarbon flow and/or control interconnection between such equipment, and where the first of such equipment is already installed, wherein said system comprises:
A system for direct vertical connection between at least two subsea contiguous equipment utilized in the production of hydrocarbon fluids, with hydrocarbon flow and/or control interconnection between such equipment, and where the first of such equipment is already installed, the first of such equipment being a PrAB unit or a HWCT, or manifold or PLET, and the second one, a pumping module to be housed within a cased borehole in the soil, wherein such system comprises a flow mandrel 237 and a template funnel 231, both integral to the said first installed subsea equipment besides a structure 256 with a hinge and where, from template funnel 231 is constructed a cased borehole 220 by drilling or blasting in the marine soil 101, the distance of said borehole being perfectly known, for housing the pumping module 222 to be directly connected to flow mandrel 237, whereby is established a mechanical and flow connection between said first and second equipment, dispensing with the use of connecting jumpers.
A system for direct vertical connection between at least two subsea contiguous equipment utilized in the production of hydrocarbon fluids, with hydrocarbon flow and/or control interconnection between such equipment, and where the first of such equipment is already installed, and wherein said system comprises a drilling base 102 fitted with two funnels 231a/231b for re-entry and guide, the first funnel 231a serving as a template for drilling petroleum well 111 and the second funnel 231b serving to construct the cased borehole 220 by drilling or blasting, for installing the module pumping 222 in the vertical position.
