Numerical Research on Mooring System of Wave Measuring Buoy

The static characteristic of a horizontal composite mooring system for wave measuring buoy is studied using 3D potential theory and catenary theory. The 3D hydrodynamic model is built for surface pontoon and wave measuring buoy to calculate the mean steady drift forces and response amplitude operators. Combined with extreme environmental conditions and catenary theory, static analysis of the mooring system is done, obtaining the results of line tension, catenary shape and safety factor etc. The research results show that the horizontal composite mooring system meets the design requirements and it is proven to be an effective mooring method for the sea area with large current velocity.
