     offshore platforms, located at severe environmental conditions, are generally subjected to two types of environmental loading; normal-condition loads such as wave-induced hydrodynamic forces and extreme-condition loads like seismic excitations. among classified categories of environmental loads of offshore platforms, those of great importance are wave-induced hydrodynamic forces in normal conditions and seismic excitations in extreme conditions.adjustable parameters of a vibration control system for offshore platforms are generally designed by considering only one type of environmental loadings; either normal-condition loads to mitigate fatigue damage or extreme-condition loads to guarantee collapse prevention. so, it is important to investigate the effectiveness of vibration control system, designed for the more influential type of external loading, when subjected to another type. also it is ideal for the system to have an acceptable performance in both normal and extreme conditions.
