Description The estimation of response parameters plays an important role in the design of offshore structure. The periodic inspection and monitoring of offshore platforms for certification needs the study of the responses of structures owing to wave and wind forces. The complex dynamic behavior of the platform to the environmental loads makes in difficult to calculate exactly the dynamic responses. The present need of the industry is to have a time saving and accurate calculation methods, which can be in good agreement with the actual response parameters. Pierson-Moskowith (P-M) spectrum is used for the calculating wave height and wave period for different wind speed. For a wind speed of 41.67 m/s, a significant wave height 14.86 m and wave period 21.66 sec is considered for the present investigation. The responses of the structure to the varying wave and wind forces at different water depth are analyzed using well defined dynamic analysis method. The industry standard StruCAD software package developed specially for offshore structural analysis is used to obtain platform displacement response under varying external loadings. In the present analysis, dynamic behavior of the structure and deflection of the platform is studied for individual and combined wind and wave forces
