Abstract
This paper examines the response characteristics of offshore structures under the simultaneous action of the wave and current. Based on the linearized equations of motion with optimization of non-linearity arising in hydrodynamic drag force term, the structural response to wave and current is computed by the random vibration approach. The general theory also suggested that the uniform current statically induces response of offshore structure that should be superimposed on its dynamic response. The comparison of dynamic response and static one yields the necessity of inclusion of static response induced by steady current force in design of offshore structures under the ambient conditions concerned.
