Mechanics of Cable Mooring Systems. Volume VIII. The Dynamic Response of Cable Arrays Subject to Large Current Induced Displacements.
Abstract
A technique has been developed by means of which the rigid-body response of a bi-moored cable system to various dynamic excitations encountered during deployment and operation can be predicted. The solution technique couples the method of imaginary reactions for solving the basic cable problem with the use of the phase-plane gamma method for solving the rigid-body equations of motion. The procedure which has been developed here was first applied to a simple model which was given initial conditions but no excitation. Its response compared favorably with an experimental observation, although showing an apparent discrepancy in the modeling of the drag forces. A typical prototype system was also analyzed. Its response to both in-plane and out-of-plane current profiles are presented. (Author)
