... technique. 139 6. Conclusions A method to evaluate the variance response for displacements and stresses of offshore structures is described. The technique is based on an equivalent cubic expansion of the non-linear drag loading. One numerical example is given, where the loading is drag dominated. Analytical...

..., the structural responses are predominantly controlled by various damping mechanisms existing in the structure [Van- diver, 1980]. Previous researchers [Michelsen and Meek, 1982] indicated that the total damping for these offshore structures in moderate sea is very low. Under such condition, even a small increase...
