design is based around the feature that allows an ROV to open the clamp subsea. This allows the user the ability to place it around existing pipelines or umbilical’s without first terminating the line. The clamp can then be placed over the flange connection and be used to fasten the two flanges together. This clamp was specifically designed to re-connect a 16” 600lb ANSI flange; however the clamp can be scaled to fit just about any flange connection. The clamp takes the place of the studs and bolts; therefore, its provides the same structural integrity that the bolts provide through the use of compressive loads as well as the material properties that
When installing the clamp an ROV installable Taper Ring must be installed on the bottom of one of the flange faces first. The Taper Ring is installed using a custom hydraulic tool to lift the Taper Ring into place on the bottom side of the flange. The Taper Ring houses magnets which allows for a magnetic attachment to the flange rather than a traditional fastening method.
