Adaptive Active Heave Compensation for all winches. Increases operational time for ROV and subsea lifting operations.
Scantrol AHC is an Active Heave Compensation control system for winches, cranes, LARS, wellhead intervention in subsea operations. The system controls the winch to eliminate vessel motion that would otherwise be transferred to the load.
Scantrol AHC includes a MRU (motion reference unit) measuring vessel heave, pitch and roll motion. The system adapts to varying load and operating conditions to maintain safe and efficient compensation without overloading the winches.
Scantrol AHC gives the winch operator precise control over the load, even when operating in rough sea conditions. This results to increased operational time and minimized weather related downtime.
Scantrol has developed an AHC toolbox that makes it possible to specify AHC requirements and find the optimum winch design to match these. This helps the winch designer to identify critical factors and to minimize power consumption.
The toolbox includes software for data logging and for monitoring of AHC performance.
Scantrol AHC is designed to perform safe and reliable Active Heave Compensation with any winch or crane used for subsea operations. The system can also control both electric and hydraulic winches, and will optimize AHC by continuous winch performance analysis.
This system is flexible and can be delivered in different configurations, ranging from a control unit with a simple operator panel or radio control, to an advanced iSYM system with multiple displays and data recorders.
