Abstract.

In the paper, a review of the current state of the knowledge in the field of heave compensation systems is presented. Three most important types of heave compensation systems such as: passive (PHC), active (AHC) and semi-active (hybrid) are described in more detail. Special attention is given to show the differences between presented in this paper heave compensation systems. In the paper also the developed by authors simulation model and test stand of hydraulic heave compensation solution is described. Its chosen simulation and experimental investigation results are presented.

4 Conclusion

The article describes a chosen heave compensation systems. In this paper Authors described a three mine types of heave compensation systems such as: passive, semi-active and active systems. The basic equations which describe the active heave compensation system are proposed in Sect. 3. Simulation model is built in MATLAB/Simulink software. In this section the test stand built by the Authors is also described. The main components of the test stand are: hydraulic motor and hydraulic cylinder. Two electrohydraulic servo valves were used to control of the hydraulic motor and hydraulic cylinder. The control system was based on PLC type Power Panel 500. In the Fig. 8 and in Fig. 10, the simulation and experimental results are presented. These results confirmed that the proposed solution can successfully compensate floor fluctuations like sea waves.
