Response Analysis of Different Mooring Parameters for a Three-anchor Buoy Integrated Observing Platform
Based on the numerical calculation model of the three-anchor buoy,the frequency domain a-nalysis was carried out in this paper.By changing the anchoring distance and the two types of anchor chain lengths unique to the three-anchor buoy,the motion response and anchor chain tension of the main buoy under different wind waves and currents were calculated.The results show that the ancho-ring distance has a significant effect on the tension of the anchor chain,but has little effect on the pitch,yaw and heave.Increasing the link chain and fixing the chain length will significantly increase the response amplitude of sway,heave and heave,and significantly reduce the tension of the mooring system.With the incident direction increasing from 0° to 60°,the tension of link anchor chain increa-ses slightly,while the tension of fixed anchor chain decreases slightly.Finally,according to different engineering requirements,suggestions on the deployment of three-anchor buoys are given to ensure their safety and service life.
