Abstract: Offshore guyed tower plateforms belong to the group of complaint offshore plateforms which are most suited for deep water exploration.The basic feature of complaint offshore plateforms is that they are design to move with the waves,in at least some degree of freedom.As far as excitation of wave frequencies is concerned,the system opposes wave forse by inertial effects.The offshore guyed tower derives its stability against lateral movement from its mooring system.In this study the responce of offshure guyed towers of random force 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 rendom wave force.The analysis includes the nonlinearities due to the morison equation of drug force,the variable submergence effect due the wave,the instantaneous position of the tower and force,excursion relation of the mooring lines.A parametric study in conducted to insvestigate and behaivour of the tower under waves,and the combined effect of wind and wave force.
