6 3/8-15K Safety Head (Compact Cutting Device)

Hydraulically operated, compact, shear and seal valve designed with high cutting performance and reliable post-cut sealing

This CCD is designed with opposing horizontal hydraulically actuated gate valves made to shear coiled tubing, drill pipe, and wire line of a given specification in the wellbore and seal from below. A seal is made after the shearing, isolating the pressure/fluids beneath the CCD. It is used in offshore and/or high-pressure applications where cutting of the well string is required without leaving a snag. The device is powered by accumulators and can be overridden via ROV hot stab in either direction.

With a reduced package size, our CCD can be easily transported and installed using economic methods, reducing overall time and costs for subsea projects.

The gate valves are fail-as-is. The external position indicator will show where the gate valve positions are at all times. A locking mechanism prevents the gates from creeping back after they have closed. In case of a failure, an override tool may be used to open or close the CCD. This override tool is ROV actuated.
