Remotely operated makebreak system

The T-WREX make-up/break-out system from Hawk Industries, Inc. is an innovative design that incorporates the features of its HAWKJAW system into a pedestal mounted configuration for remote operation. Ideally suited to the harsh environments of offshore drilling, as well as large-scale, land-based applications, the system is available in the Junior (Fig. 1) and Senior (Fig. 2) models. Both models’ features include:

• Operation by remote console
• Preset torque regulator ensures proper make-up of each joint
• Low-torque warning system prevents under-torqued connections
• Spins and torques in under 15 seconds in most application
• Infinite pipe size adjustability within working range of tool
• No jaw/die changes required for different pipe sizes
• Hydraulic rotation from mouse hole to rotary
• Tilt adjustment for mouse-hole operations.

The system’s applications include: 

• Coring running/pulling
• Casing milling/cutting
• Tripping drillstring
• Workover trips
• Sidetrack/re-entries.

• Drillstring components during idle time
• Initial and additional pickup/laydown of drillstring
• Logging operations
• Cementing operations.
