Simulation of an ahc system during offshore installation
An active heave compensation system (AHC) is described in the paper. Active control enables us to compensate vertical vessel motions generated by sea waves. Such systems are used on a special offshore installations and construction vessels, performing the necessary work related to subsea field exploration. The most common AHC systems are based on an application of winches. Among many possible solutions, an electric drive is often used in order to control the speed and the moment, by the application of a frequency converter. The simple control system presented in the paper allows its real-time application on an onboard PC and through a PLC software. The system is implemented and operates currently on an offshore pipelay vessel.
