Offshore Guyed Tower platform belongs to the group of compliant offshore platforms which is most suited for deep water search for oil and gas. The basic feature of compliant offshore platform is that it is designed to move with the waves, in at least some of its degrees-of-freedom. In this study the response of offshore guyed tower to random forces generated by wind and wave is investigated. The exposed portion of the tower is subjected to the action of turbulent wind, while the submerged portion is acted upon by random wave forces. The analysis includes the nonlinearities due to drag force, the instantaneous position of the tower and force-excursion relation of the mooring lines. A parametric study is conducted to investigate the behavior of the tower under wave and the combined effect of wind and wave forces.
