Abstract
The analysis of moorings for a subsurface buoy system is complex because of large changes in configuration, load dependence on the position, shape and orientation of the system, nonlinear load behavior of cable, mooring boundary, etc. A parametric study carried out on moorings, using an indigenously developed finite-element program MOOR, is reported. An incremental method and Newton-Raphson iterative schemes were used to develop the program. The effect of various parameters such as current velocity, water depth, net buoyance (pre-tension) of the buoy and specific weight of fluid on the horizontal deflection are studied. Dimensional analysis using Buckingham Pi method gives nondimensional variables. Using the nondimensional terms, design charts have been prepared. The above charts can be used for the analysis and design of moorings for a subsurface buoy system. The influence of different parameters on the design is discussed.
