Abstract: The disclosed subsea clamp tensioning system includes predictability of gasket pre-load to input closure and allows a subsea clamp tensioning system to be closed and made-up without the hindrance of frictional loads that will cause a loss of tension in a drive screw. In an embodiment, the subsea clamp tensioning system tensions the drive screw by applying a set torque load into an API class torque bucket which translates into an applied tension at the drive screw. The tension load on the drive screw applies the gasket pre-load required to create a metal-to-metal seal between the two clamp hubs. Once complete and tested, the subsea clamp tensioning system may be removed and mounted onto a connector tool for retrieval to the surface.
