AN ANALYTIC MODEL TO PREDICT THE DYNAMIC LOADING OF A CABLE SYSTEM IN A LINEARLY VARYING CURRENT PROFILE

A discrete mass, lumped parameter model is used to describe the dynamic loading of a cable system in a linearly varying current profile. Taylor adds to the work of Geoller and others by considering a linearly varying current. Dynamic cable drag, current cable drag, cable weight, buoyancy, inertia, and viscoelastic forces are considered by modeling cable segments with a spring, mass, and dash-pot system. The model was found to be applicable to moored and free-floating cable systems with long cables. The theoretical model was found to be accurate when compared to data taken in an in-situ test.
