Abstract
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.
