Abstract: The present invention refers to a completion riser joint (1) shearing by the shear ram of the blow-out preventer (BOP) (2), to be coupled, at its lower part, to the column hoist running tool and, at its upper part, to the completion riser column, the referred shearing completion riser joint (1) comprising upperly a riser bolt (3), connected at its lower portion to an access pipe (4) to the production column, shearing by the shear ram of the BOP (2), enveloped by hydraulic lines (5, 6) that allow the actuating of the column hoist running tool and the access to the annular, the referred pipe (4) being connected lowerly to a re-entry mandrel (8), which function is to allow the locking of the recovery tool (12) and, through it, allow the hydraulic continuity for actuating the unlocking function of the piping hoist and, following, its release, and lowerly to a riser box (9) on top of the piping hoist running tool.

Abstract: An integrated oil drilling and producing base includes a single guiding funnel for guiding a wet Christmas tree into the proper position on a high pressure well head. The single guiding funnel has a cylindrical downcomer for resting directly on the high pressure well head, at least one cradle on the guiding funnel and at least one pipeline terminal hingedly mounted on said at least one cradle. The guiding funnel has a plurality of slits for allowing passage of a plurality of pipelines therethrough for connection to a respective terminal on the funnel and for connection of each terminal to the wet Christmas tree.
