Dynamic Simulation and Field Experiment of Submarine Cable during Laying and Recovery

摘要

A submarine cable encounters the greatest tension when it is laid down to the sea bottom from a cable ship or is recovered for shipboard repair. It is very important to know the cable dynamics for designing the cable and determining its safety handling conditions during lay and recover operations. Numerical simulations and field experiments on dynamics of a submarine cable during laying and recovery are shown in this paper. The 2-dimensional lumped mass method is used to calculate the motion and tension of the cable.
