Mechanics of Cable Mooring Systems. Volume III. Parametric Evaluation of Bi and Quad Cable Array Systems.

摘要

This report summarizes the results of a parametric sensitivity study of two cable array systems. The arrays are composed of either two or four mooring legs connected to a large cylindrical member,which is considered to be rigid. The parameters selected for determining their effect on the response characteristics of each system when subjected to directional currents,include:cable diameter and weight;length of the cylindrical member;buoyancy;anchor span and array height corresponding to nominal values ranging from 5,000to 20,000ft. Each combination of parameters defining a particular array was subjected to a uniform current which was varied both in magnitude and direction. The array was then analyzed to determine this system's configuration,and the loads developed both internally and externally on the structure. (Modified author abstract)
