This paper mainly studies the wave-free characteristic of heave motion of a sandglass-type floating body to overcome the limitations of traditional ship-type and cylindrical floating, production, storage and offloading units. In the first instance, the theoretical and numerical methods are used to determine the added mass and damping wherein the heave motion can be decoupled. The existence of wave-free characteristic of heave motion is theoretically and numerically verified. Moreover, the heaving quadratic transfer function of second-order wave drift force is calculated and its performance has been discussed. Finally, the relationship between wave-free frequency and wave spectrum is selected as the design principle of the shape parameters. On this basis, some experiments of new sandglass-type and cylindrical models are carried out, which coincide with the numerical predictions very well and show that the new design based on wave-free frequency can significantly improve the heave motion performance.
