 Cameron's Hydraulic RF Riser Running Tool is designed to provide a fast, safe and convenient method for running and testing riser joints. The tool has an RF flange on the lower end to stab onto the riser connector and hydraulically lock into place. When hydraulic pressure is applied to the tool, a cylindrical sleeve with a tapered nose is driven behind a split ring, causing the ring to expand into a groove in the RF flange. Once the ring is expanded, the sleeve continues to travel until cylindrical surfaces on the ring and sleeve engage, preventing the possibility of the sleeve backing off. When pressure testing of the auxiliary lines is required, the running tool is left locked in place and the test plugs are lowered into position. Features: - The two-piece mandrel is designed so that common rig tools can be used for handling. The standard mandrel utilizes 4-1/2" IFTJ threads; optional mandrel threads/shoulders are available. The two-piece body/mandrel design provides the ability to change out the mandrel due to wear, elevator damage, or a change in tool joint threads or elevators without the need to repair/modify the entire running tool assembly.
- Locking pressure can be relieved and the tool remains locked, so a riser joint may be run without dragging hose along with the tool. Removeable test plugs eliminate the need to stab the test subs every joint.
- Alignment pin provides orientation of the running tool, ensuring proper position for installation of the removeable test plugs for testing auxiliary lines.
- Position indicator also serves as an emergency manual unlock device.
