Canrig Drilling Technology Ltd offers a complete range of electric Top Drive models with hoisting capacity from 275 to 750 tons. In our DC units the horsepower for each model increases as the hoisting capacity is increased. The gear ratio for each model can be altered to provide varied torque to speed ratios. Canrig’s AC top drives range in hoisting capacity from 500 to 750 tons. The use of AC technology produces improved performance resulting in a “fatter” torque curve. A brief description of our models is as follows:

PRODUCT INFORMATION

FEATURES AND BENEFITS

Ø Features and Benefits of a Canrig Top Drive Drilling System

1. Integral Swivel • Eliminates fatigue failures associated with threaded connections.

2. Hydraulic Torque Boost • Continuous rotation of up to 5 RPM • Precise directional control

3. Industry Exclusive Floating Quill for Soft Stabbing and Thread Advance Compensation • Prevent thread damage during make-up and break-out.

4. Polymer Slide Guide Runners • Fewer components, significantly reducing the risk of falling parts. • Improved load distribution

5. Counter Balance Feature • Duplicates the dampening effect of the spring on a conventional hook.

6. Dual Lower Well Control Valves, One Manual and One Remote Actuated • Provides optimal well control

7. Remote Actuated Upper Well Control Valve • Improves well control options and acts as mud saver valve.

8. Local or Remote Blower Option • Operator selected-based on hazardous area requirements.

9. Wireline Guide System • Enables efficient wireline entry.

10. Direct Connection to Rigs Traveling Block • Reduces system height and weight by eliminating the block hook.

11. Disc Brake • Allows infinite positions for directional orientation. • Provides inertia braking.

12. AC or DC Electric Drive Motor • Allows operator to select configuration best suited to the application.

13. “Soft Torque” Vibration Control System Available • Reduces “slip-stick” thus improving drilling efficiency.

14. Remote Control of Pipe Handler Orientation and a Lock • Permits driller to maximize efficiency of pipe handling operations.

15. By-Directional Link Tilt Function • Permits overdrill thus allowing connection to be made with bit off

bottom. 16. Load Path Integrity – No Thread Connections in the Load Path

• Eliminates fatigue type failures associated with threaded connections.

PRODUCT INFORMATION

AC TOP DRIVE MODELS

AC Technology Since the advantages of using top drives are well documented, the decision for most operators is whether to use DC or AC technology. Both have advantages that warrant consideration depending on application. The primary benefit of AC top drives is a significant better power factor. AC motors also have a better speed range and can be run at 200% of base speed and above. The horsepower characteristics of an AC motor are far superior to the DC equivalent. DC motors can maintain maximum horsepower at only one speed while AC motors maintain fill horsepower from base speed to approximately 150% of base speed. Other advantages to our AC Top Drive Drilling Systems are:

• Can stall motor for an indefinite period, with zero to maximum torque applied. • Enclosed, EExe or TEFC motor possible. This would eliminate the blower

hose (a rather cumbersome, but necessary feature on the DC motor). • Less maintenance due to lack of brushes. With a TEFC motor, this becomes

double important, considering that no dirt or moisture will be entering the motor and its windings.

• By utilizing a 12 pulse front-end variable frequency drive, substantial reduction in harmonics to the point where it will meet and exceed requirements of IEEE 581 standards, can be achieved. This feature becomes valuable if drilling power is obtained from Hiline Utility distribution.

• Our innovative modular design of the drive also allows for plug and play repair and maintenance.

• New technology. Utilization of latest components and engineering know-how.

Ø The Fixed Torque Guide Canrig Torque Guide Systems provides lateral guidance and torque reaction for the top drive unit without imparting torsional stresses into the mast/derrick. The Flanged Type Torque Guide is divided into sections corresponding to the mast sections. Each guide section is laterally fixed to its mast section with torque-isolating connections. The Torque Guide sections are joined with bolted flanges. Subject to mast erection stress constraints, the Flanged Torque Guide can be installed horizontally and erected with the mast. 1. Four (+/-) section Torque Guide, custom built for the mast/derrick. 2. Flange connections between the sections. 3. Mast connection brackets (2 per section):

• Torque isolating. • Free axial movement of the torque guide relative to the mast/derrick. • Adjustable lateral positioning. • Welded attachment to the mast girts (Standard); clamped-style

optional. 4. Transport Skid for the Top Drive Unit built into the bottom section of the

Torque Guide. 5. Application engineering and installation drawings. 6. Mast erection stress analysis and any associated mast upgrades are

excluded. 7. Installation, alignment and labor costs are excluded.

Ø Top Drive Services – Mast/Derrick Mounted (Fixed)
