mTrack is an AHC controller with integrated MRU and all the tools you need to make it work with your winch or crane. mTrack makes it possible to design affordable AHC solutions for all winches and cranes that are used for subsea operations.

mTrack is an Active Heave Compensation controller that can be used with both new and existing winches. The flexibility of the controller makes it fast and easy to integrate with any winch or crane control system, and includes tools to simplify test and commissioning. mTrack has an internal MRU (motion reference unit) measuring vessel heave, pitch and roll motion, and uses Scantrol’s proven AHC technology to control the winch or cylinder to eliminate vessel motion being transferred to the load. The winch operator has precise control over the load, also when operating in rough sea conditions.

An increasing number of vessel owners specify AHC for their subsea handling equipment to increase their operational window. Scantrol’s AHC technology is recognized in this industry and our AHC solutions can help you fulfill your clients requirement in a safe and reliable manner.

mTrack is designed to provide safe and reliable AHC control of all types of winches and cranes that are used for subsea operations.
mTrack has predefined setup for various cranes, LARS ,and winch configurations in order to simplify system integration and commis-sioning. Standard configurations include knuckle boom cranes, tele-scopic cranes, LARS, electric winches, hydraulic winches and cylin-ders.

mTrack comes in two versions, mTrack and mTrack+, so you can choose the model that suits the capacity of your winch and the com-pensation level that is required.
mTrack can compensate for up to 4 meter vessel motion and is suit-able for winches with speed capacity of up to 1.5 m/s. This is within the range where most AHC applications are normally used.
mTrack+ compensates for up to 8 meter vessel motion and is suita-ble for winches with speed capacity of up to 3 m/s. mTrack+ comes with an external MRU.

mTrack includes AHC control for winches and cylinders. In addition to Scantrol’s proven AHC control functions, mTrack includes tools to streamline design, commissioning, and operation of your AHC application.

  • AHC Analyzer - Design the optimum winch to meet required AHC performance, or determine AHC performance of an existing winch
  • Auto Tuning - Automatically tune the winch to compensate for potentially changing winch characteristics. Ensures efficient installa-tion and calibration.
  • Dynatest -Verify winch performance at the factory or at quayside, and avoid expensive sea trials for AHC tuning.
  • AHC Performer - Continuous monitoring of vessel motion and winch operation. The operator can see the percentage of winch capacity used for AHC, to make educated decisions .
  • Remote Assistance - Support, operational help, software upgrades – all available through the vessels internet access.
  • AHC Logger - Recording of winch and system performance during AHC operation
