Casing-Stabilizer Arm

Aker Solutions has developed a casing-stabilizer arm (CSA) that eliminates the need for a person to be elevated on a derrick for tubular makeup. The CSA is designed for both offshore and onshore rigs. The stabilizing mechanism is stowed approximately 33 ft above the drilling floor and includes an internal hydraulic cylinder that extends and closes the padded jaws operated by a radio remote control. The CSA uses only three hydraulic cylinders to position and mobilize the pipe jaws: lifting, extension, and clamping cylinders. Aker’s unit also provides increased safety features that allow the device to interface with the rig’s anticollision-zone-management system.A warning and alarm system is built into the CSA along with an emergency-shutoff control. Additionally, a shear pin is installed on the unit as a safeguard for unexpected downward clash by hoisting equipment. The CSA is equipped in tubular capacities of 2⅞- to 22-in. diameter without changing jaws. Additionally, it offers wireless remote control and local manual control.
