Reasonable layout, reliable installation, economical operation, and facilitated control are the major goals for the research and development of deep seabed mining systems. Kinematic condition and dynamic characteristics of the systems are of direct and important influence to attaining the goals. Based on the results achieved in the research and development of deep seabed mining technology in recent years, the main factors influencing the kinematic condition and dynamic characteristics of the systems, including sea current, sea wave, sailing velocity of the mining ship, weight and shape of the underwater nodule storage, and moving pattern of the nodule collector, are studied and analyzed in this paper. Relevant conclusions would be useful for the layout, design, operation, and control of the systems and corresponding equipment.
