4.9.3 AHC - ACTIVE HEAVE COMPENSATION
SMC has developed a remote heave function that accepts dynamic crane position data for active
heave compensation in marine crane applications.
A failsafe handling system must be built into the system so that if there is a failure in the IMU, PLC or
the encoder feeding the active heave operation will be cancelled automatically.
Note that SMC will not be responsible for damages that occur related to Active Heave Compensation.
With the remote heave for Crane Operations active, the IMU will continually calculate the remote
heave data based on the information that is supplied to the IMU from the crane encoders.
Remote heave and remote heave velocity data is then calculated continuously for any requested
single point location along the crane boom which can be used to compensate for the vessel motions
during crane operations.
Tick the checkbox Remote heave for Crane Operations (AHC) in the remote heave tab and the crane
settings will be enabled.
