Abstract : This study is an attempt to systematically investigate the behavior of selected cable parameters in relation to deep water mooring applications under three dimensional, steady-state loading conditions. The emphasis of this report has been placed on quantifying the three dimensional geometry and reactions of a mooring line in a directional uniform current for specific combinations of support positions, cable length, weight and diameter. Included is a study of both negatively and neutrally buoyant cables for water depths ranging from 5,000 to 25,000 ft. The solution procedure incorporates a finite element representation of the cables and the method of imaginary reactions for the calculation of the equilibrium configurations. The accuracy of this procedure is examined for the catenary loading through a comparison of cable configurations and support reactions obtained from a direct solution of the catenary equations and from the use of the finite element representation.
