AHC
Active heave compensated (AHC) cranes and winches require a motion sensor to measure the vertical motion at the crane tip or winch. The Marine MRU can measure the heave motion at user selected remote monitoring points.

The Marine MRU is ideal for AHC applications especially due to its high and reliable performance in irregular waves. Where some other MRUs struggle to give accurate heave measurements in irregular waves, Norwegian Subsea MRUs are designed to deliver the highest performance in real sea conditions.
It is easy to interface the MRU with your PLC with industrial ethernet communication such as Modbus TCP and Ethernet/IP.
