Skip lifting is a new concept of mechanical lifting system for deep-sea mining. It is expected that the skip lifting is capital cost effective and energy efficient compared to hydraulic pump lifting system. Furthermore, the less by-products of seawater and sediment is very attractive in the aspect of environment. This paper presents fundamental results of scaled model test conducted for the purpose of technological feasibility study on skip-lifting system. Main measurement factors are system configuration, angular response and horizontal acceleration of buffer station. It will provide reference data for the pilot test and the commercial realization. The hydrodynamic resistance of skips obtained from single skip test can explore the main composition of water resistance.
