Abstract

Abstract: Hydrodynamic performances of ocean data buoy and mooring system have the important influence on measuring precision of observation parameters. The mooring system has a larger effect on the movement and force of ocean data buoy， so the related research on the hydrodynamic characteristics of mooring system has always been a the focus of the design and development of ocean data buoy. The hydrodynamic performances of three different types of mooring systems under the combined force of wind and waves are studied by using the measured data from the northern Chu Island waters off Weihai through numerical simulation and physical model test. The experimental results show that the different mooring systems have significant effects on the hydrodynamic performance of buoy system. The half-tension-type mooring system performs best for fixed point observation，but has higher requirements on the reliability，which is suitable for the situation of requiring higher observation accuracy. The inverted s-type mooring system is more convenient to lay out，and has stronger resistance to extreme ocean environment，but its swing motion is more obvious，so it is suitable for use in open deep sea areas. The slack type mooring system is fall in between half-tension-type and inverted s-type mooring systems.
