Control Performance Simulation on Heave Compensation System of Deep-sea Mining Based on Dynamic Vibration Absorber
The Heave compensation system is essential for deepsea mining to extend the operational weather window and improve the operation safety and efficiency. A novel heave compensation system compositely acted by dynamic vibration absorber combined with accumulator is proposed in the light of 5000m deep-sea polymetallic mining system of China. The composition and working principles of the heave compensation system is presented, and a corresponding mathematical model of this system is built The main parameters of the heave compensation system are selected. The mass of dynamic vibration absorber, spring stiffness and damping coefficient are calculated and simulated by MATLAB. The performance of the proposed heave compensation system was simulated and analyzed in time domain. The results show that the satisfactory control effectiveness can be obtained in the overall sea state 4 of Chinas deep-sea mining field. Therefore, the designed passive heave compensation system compositely by dynamic vibration absorber combined with accumulator is able to isolate the pipeline and its deployment platform from the bending loads induced by the vertical motion of deep-sea mining ship in rough seas with high simplicity and less energy consumption.
