DETAILED DESCRIPTION OF THE INVENTION

[0013] According to FIG. 1, it is noted that the equipment for the installation and removal of plugs from submarine wells comprises a hydraulic cylinder (1), is coupled to the specific tools (9) for the installation and removal of plugs (2) in column suspenders (3) or WCTs (4).

[0014] In FIG. 2, it is noted that the hydraulic cylinder (1) will remain anchored by means of a locking mechanism (5) to a tool (6) which will be part of the installation or removal assembly of the WCT of the oil well. Said hydraulic cylinder (1) can have multiple seals (7) isolating the interior of the well from the external environment, and can be, in contingency, removed with or without the plug and plug tools from the place where it is anchored. For this, said hydraulic cylinder (1) has in its upper part a compatible profile with tools for recovering (8).
