Modeling and Simulation of Disturbance Motion for Submerged Mooring Platform

Submerged mooring platform is widely applied to hydrological monitoring devices such as buoy and subsur-face buoy, and to underwater battle platform such as moorage mine. The platform will drift, descend, pitch and yaw, or even perform a complicated cycling motion to influence the initial calibration of the carried devices. In this paper, a typical submerged moorage platform is studied by dynamic modeling and simulation. A three-dimensional equation of motion is established to analyze the balance and disturbed motion of the horizontal submerged platform attached by fork connection. The effects of system parameters and mooring parameters on the stability of disturbed motion are analyzed via simulation, and some methods for improving the stability of the platform are presented.
