Add AHC to your PHC and avoid problems when drilling or coring in soft or fractured ground
Scantrol's new AHC solution makes it easier and more affordable to retrofit AHC on existing drilling rigs.
Install mTrack AHC Controller and take the Vessel Motion out of the Equation
• Off-the-shelf AHC controller with integrated MRU.
• A game-changer that makes AHC affordable even for smaller winches and cylinders used for subsea operations.
• Includes all the tools you need for easy installation and commissioning, no need for expensive experts.
Benefits
Scantrol AHC works in conjunction with the PHC to increase vessel motion compensation up to 95%. The mTrack AHC Controller measures vessel motion by a built-in motion sensor (MRU), and controls the AHC cylinder accordingly. This eliminates the errors caused by friction and volume variations in the PHC system to improve the stability of your drilling or coring tools.
Scantrol AHC offers the following benefits for drilling and coring operations:
• Stabilize drill string motion
• Keep constant WOB
• Smooth torque
• Better core quality
• Improve drilling ROP
• Less core jamming
How to add Active Heave Compensation (AHC) to your Passive Heave Compensation System (PHC)
1. Install one or two active cylinders in parallel with the passive cylinders. The stroke length must be identical to the passive cylinders, but the cylinder volume will be significantly smaller. A stroke sensor is required if it is not already installed as part of the PHC system.
2. Install hydraulic powerpack and cylinder control valves.
3. Install mTrack AHC controller and connect it to cylinder valves and cylinder position sensor.
4. Run Auto Calibration and Dynatest to test and verify AHC performance.
No sea trials required.
No hidden cost.
There will be no change to the PHC system, and its basic operation will remain the same.
Scantrol AHC can be turned off and completely isolated from PHC when in situations when AHC is not required.
