Studies of dynamic response of a model of a compliant offshore platform
Using simple structural and hydrodynamic models, a parametric study is made of the effect of the various parameters that influence the dynamic response of a compliant offshore structure in 2,000 ft of water. The parameters examined include the effects of different sea states, the stretching scheme used to approximate the near surface fluid kinematics, the horizontal variation of fluid kinematics; the effects of fluid-structure interaction and current; and the number of modes considered in the computation of the response. The dynamic responses of the structure, including maximum displacements, shears, and bending moments, are presented both in tabular and graphic forms. The sensitivity of the responses to the various parameters involved is examined and the practical implication of the results is discussed.
