US 12,644,480 B2 · Device for removing misalignments between flanges

Abstract

A device for removing misalignments between flanges of pipeline ends. More specifically, a device that, operated by an ROV, allows flange holes at the ends of subsea pipelines to be aligned so that interconnection operations between said pipelines can be embodied. To this end, the device described herein comprises an elongated metallic body having at least two diameters and presenting a gradual reduction between the component diameters. Additionally, a fixed nut is mounted on the larger diameter side of the elongated body, followed by a manipulator for administration by the ROV. On the other hand, a movable nut is mounted on the smaller diameter side of the elongated body, and the tightening movement made by the ROV on this movable nut causes the device to pass through the holes to be aligned, precisely, in the direction of the larger diameter of the device of the invention.
