Study on Playback Technology After Restoration of Submarine Cable in Deep Water Area
By exploring the key problems in the process of playback of repaired submarine cable into the seabed in deep water area,this study analyzed the key parameters and dangerous positions of submarine cable in the process of playback,carried out theoretical analysis and numerical calculation on various bending protection devices and motion parameters in the playback process,established a simulation model,and selected appropriate simulation parameters to simulate the playback process.The influence of water depth and cable residual length on the stress state of the cable during the process of playback is studied.Through the results of this study,the key parame ters in the process of submarine cable playback can be designed to avoid the bending failure of submarine cable in the process of playback,reduce the maintenance cost of submarine cable,and improve the maintenance efficiency of submarine cable.
