چکیده
Characteristics of heave compensation systems used on a marine drilling platform or drill-ship are analyzed. An active heave compensation system with two lift cylinders is proposed by COMRA (China Ocean Mineral Resources & Association), which will be used in 1000-m depth ocean poly-metallic nodule pilot mining system. A corresponding virtual prototype of this system is developed. The parametric analyses and operation process simulation have been carried out on this virtual prototype system. The results show this proposed virtual system is feasible. Furthermore, a fuzzy logic control is applied to the design of this system. The control performance is investigated based on the simulation of this virtual prototype. The results show that the designed virtual prototype of heave compensation can reach the design target in virtual simulation.

Simulation of fuzzy PID Control of heave compensation system for deep-ocean mining
Abstract. A heave compensation system is one of the absolutely necessary instruments to secure mining operation. The heave compensation system includes a heave compensated platform which is to compensate heave motion and a gimbaled platform which is to accommodate pitch and roll. The simulation of a nonlinear model based on fuzzy PID control is performed. The results show that the compensation ...
