In this paper, a novel multi-layer framework FPV is proposed, and a novel pile fixed-horizontal mooring systems is design for this FPV. The dynamic motion response and mooring line tension characteristics of the FPV under different connection methods, water depths and environmental load directions are numerically investigated. Results show that the surge/sway motion response of the FPV is less than 1.35m, and the heave motion response of the FPV is less than 0.5m. The roll/pitch motion response of the FPV is no larger than 6.5 degree, and the mooring line tension of the FPV is no larger than 110kN. It should be mentioned that the discrepancies of the motion response of the FPV under different tidal level is not significant, and the maximum difference percentage is not larger than 54%. It indicates that the multi-layer framework FPV associated with the pile fixed-horizontal mooring system proposed in this paper can be applicable to the environmental conditions with ultra-shallow water depth with significant tide range.
