Abstract:

         The horizontal mooring system of SBF3-2 wave buoy includes an anchor, a chain, two nylon wires and a surface pontoon, in which the mooring line connected the buoy always keep horizontal. We employed multi segment  catenary  theory to calculate its line tensions and catenary shape. Analysis results show that this mooring system is available for the sea area of high current velocity. It can improve its wave following, and also anti overturn performance and the measurment accuracy.

Key words: wave buoy, horizontal mooring, multi segment catenary theory
