Dynamic analysis on the novel concept of underwater tracked vehicle and long flexible riser in deep-seabed mining system

Abstract

In this study, we proposed to use buoy structure as a method which can be disconnected motions of two devices. The mining robot is greatly influenced heave and pitch motion by the flexible pipe. A connection between the buoy structure and the mining robot is developed as a revolute joint type. The flexible pipe is attached at the buoy structure. The heave and pitch motion of the mining robot can be independently moved by this mechanism. Dynamic analysis is fulfilled for verification of this mechanism.the mining robot is developed as a revolute joint type. The flexible pipe is attached at the buoy structure.
