Can the MRU output remote heave?

Yes, the MRU can output heave measurements, including position, velocity and acceleration at 2 remote monitoring points.

In addition, you can use the measurment point at the centre of gravity and select the CoG position as the position of your 3rd monitoring point. Note: CoG position is not used as part of the calculations and can be set to any position.

The location of the remote monitoring points can be configured graphically in the configuration software.

An example where this is usefull can be one MRU that provides output for 3 active heave compensated winches.
