Field test system for investigating dynamic ice forces on jacket structures and platform safety guarantee in the Bohai Sea

In order to investigate the dynamic ice forces acting on compliant jacket platforms and to guarantee the platform safety in the Bohai Sea, an extensive measuring system is planned and installed on several prototype structures, which consists of: (1) specially designed load panels to detect dynamic ice forces of high fluctuating frequencies; (2) suitable sensors to measure structure topside's acceleration or displacement; (3) high-definition video cameras to record videos of ice, which are employed to observe the ice–structure interaction phenomenon and to calculate ice thickness/velocity; and (4) meteorological station to record corresponding information like air temperature, wind speed and direction etc. All the signals from different devices are concurrently processed and stored into a central computer. The measuring system has provided fruitful information for the research of dynamic ice force. Meanwhile the structural acceleration response prediction model and the platform safety guarantee system in the Bohai Sea were established based on the measuring system. Some typical events and results are shown in the paper.
