Active Heave Compensation for ROV Operations
Worried about damaging your ROV or TMS?
Why AHC is Essential for ROV Operations
Remotely Operated Vehicle (ROV) is an underwater robot used for subsea operations. Controlled from a surface vessel via an umbilical cable, ROVs are equipped with cameras, sensors, and robotic arms to perform tasks like pipeline inspection, equipment maintenance, and scientific sampling at great depths, where human divers cannot operate safely.
However, vessel motion due to waves impacts ROV performance, leading to damages, inefficiencies, safety risks, and increased operational costs. mTrack Active Heave Compensation (AHC) Controller stabilizes the Tether Management System (TMS) and counteracts vessel motion in real time. This ensures smoother operations, minimizes mechanical strain on umbilicals, and enhances overall safety and efficiency, even in rough weather conditions.
The Challenges of ROV Operations
Weather Dependency: Rough seas can make it difficult to launch, recover, and operate ROVs safely.
Damages: Vessel motion can cause damage to the ROV and TMS
TMS Instability: Without compensation, the TMS moves unpredictably with the vessel, increasing docking risks.
Umbilical Stress: Excessive movement causes wear and tear on umbilicals, reducing their lifespan.
Operational Delays: Unstable conditions lead to downtime, affecting project timelines and costs.
Key Benefits of Scantrol AHC for ROVs
Increased Weather Window: Reduce downtime and extend operational capacity.
Safe and Precise Docking: Maintain TMS stability for seamless ROV docking.
Reduced Umbilical Wear: Extend the lifespan of umbilicals by eliminating peak loads.
Cost-Effective Solution: No need for expensive sea trials, test and tune at dockside.

Real-World Applications of Scantrol AHC
Many ROV operators worldwide have successfully retrofitted Scantrol AHC to existing Launch and Recovery Systems (LARS), enhancing stability and reducing downtime. Scantrol AHC is installed on new and upgraded winches from a range of recognized LARS manufacturers: Dynacon, Fugro, Hydramec, Ennsub, Odim, Lawson, Lidans, Evotec, SMD, Ibercisa, Kongsberg and Rolls-Royce
Good results and high performance were witnessed by the client . The system is now operational and all feedback from the client has been positive
Danny Church, Managing Director at Hydramec.
“With Scantrol AHC the ROV pilot will be able to maintain the position of the TMS unit while focusing on docking and undocking operation the ROV in order to prevent any disastrous situation of damaging the delicate tether, which is the “life line” of any ROV system.”
- William Lee, Service Line Manager at Fugro Subsea Technologies in Singapore,
“With this equipment, we reduce weather-related downtime, ensuring the achieved value pays back the investment spent on the system.”
- Hans Martin Gravdal, former CEO of Swire Seabed
How to Retrofit mTrack to Existing Winches
Many winches are suitable for AHC operation, reuse of your winch represents a major cost reduction compared to buying a new winch and results in a reduced carbon footprint.
We can help you determine if your winch is suitable for AHC.
