A static analysis of the preliminary guyed-tower design described in Part 1 indicated that the employment of clump weights along the guy cable is attractive because the weights limit the maximum line load during extreme static platform deflections. From a dynamic and metal-fatigue point of view, clump weights are undesirable: the cyclic bending moments increase the maximum design guy tension, requiring larger cable dimensions. However, great amounts of platform energy may be dissipated when the weights are lifted off and laid down on the seabed, thus dampening the platform's motions. A dynamic guy analysis - necessary for both traverse and axial directions - indicated significant dynamic (hysteretic) guy responses that did not coincide with the statically predicted responses.
