INVESTIGATION OF EFFECTS OF DAMPED AND NON-DAMPED SYSTEM ON A PLATFORM STRUCTURE.

Damping is one of the significant way of isolating vibration or remoteness of oscillation in a platform structure system which is usually carried out to reduce the effect of loads on the system and entire platform structures from been damages. The area of focus of this research work is to investigate the effects of damping and non-damping system on a platform structure and to analyze the effects of wave load on periodic support of isolation system. The platform on offshore was considered as area of focus to investigate the performance of the suggested mitigation system of oscillation about an equilibrium point for offshore platform. This work study will examined the value of parameter and modeling the fitting of an intermittent strut on offshore platform to enhance isolation system due to its attenuations ability over broad frequencies was presented. It was observed that the peak acceleration of the platform and the peak displacement on the platform under wave load excitation gave maximum periodic effects at minimum inter-structure drift and verse versa
