Subsea lifting demands precision in dynamic sea states. Conbit’s AHC conversion service transforms your existing crane into a high-performance lifting system capable of compensating for vessel heave. This retrofit improves safety, reduces load impact, and expands operational weather windows—without the cost of a new crane.
Technical description: Active Heave Compensation integrates sensors, hydraulic or electric actuators, and control algorithms to counteract vessel motion. The system adjusts winch speed in real time, keeping the load stable relative to the seabed.
Step-by-step procedure:
o 1) Feasibility study (crane specs, winch type, power availability).
o 2) Engineering design (control system, sensors, integration with existing PLC).
o 3) Hardware installation (motion sensors, hydraulic/electric actuators, wiring).
o 4) Software configuration and algorithm tuning.
o 5) Factory Acceptance Test (FAT) and offshore commissioning.
Benefits: Increased lifting precision, reduced dynamic loads, extended operational limits, and compliance with offshore lifting standards.
Conbit can assist: We deliver turnkey AHC retrofits, including design, installation, and commissioning worldwide.
