摘要

A numerical study on the heave reduction of a floater connected to a submerged body was conducted in the potential-flow computational domain. A two-degrees-of-freedom system was modeled to control the vertical motion of a floater and a submerged body. The drag force acting on the submerged body was applied to the equation of two-body motion to model the viscous effect. A parametric study revealed variations in the frequency of the maximum floater heave reduction according to the dimensions of the submerged body and stiffness of the connection line. Hence, a heave response amplitude operator (RAO) of the floater can be regulated by a two-body interaction. The ratios of the heave reduction were compared for various body conditions in regular waves. The optimal conditions for the maximum floater heave reduction were predicted regarding the resonant frequency of single body motion.
