seismic control of offshore steel jacket platforms using tuned liquid column damper

Offshore platforms are widely used to explore, drill, produce, store, and transport ocean resources and are usually subject to environmental loading, such as waves, winds, ice, earthquake and currents, which may lead to failure of deck facilities, fatigue failure of platforms, inefficiency of operation, and even discomfort of crews. in order to ensurereliability and safety of offshore platforms, it is of great significance to explore a proper way of suppressing vibration of offshore platforms. earthquake loading has to be considered when the offshore platform is constructed in active fault zone.
