Modelling and Motion Response Analysis of Seafloor Drill Launch and Recovery System Under the Action of Marine Environment
Based on the launch and recovery system of seafloor drill will cause the seafloor drill to swing under the disturbance of the marine environment such as wind and waves.By establishing the dynamic model of the launch and recovery system,the different wave heights,wave direction angles and wind speeds of the launch and recovery system under regular waves are analyzed.Influence on the swing angle and relative displacement of the seafloor drill.The research results show that under the influence of wave height,wave direction angle and wind speed,there are obvious differences in the swing angle and relative displacement of the deep-sea submarine drilling rig before and after entering the water.With the increase of wave height and wind speed,the in-plane swing of the seafloor drill.The angular variation range is small,the variation range of the out-of-plane swing angle increases accordingly,and the relative displacement also increases continuously;with the increase of the wave direction angle,the swing angle and relative displacement of the seafloor drill gradually increase.The obtained conclusions can be used for the prediction and control of the swing of the launch and recovery system of the seafloor drill,and provide reference for the technical staff.
