摘要： The relative motion problem in the vertical direction is proposed, originating from the conceptual design of a new type floating drilling production and an offloading system. The theoretical model is established by decoupling the motions of the hull and dry wellhead deck, and the indoor test platform is built using the semi-physical simulation method. The feasible test scheme is determinated according to hull heave response spectrum. Under the harmonic excitation, the experimental results agreed with numerical results perfectly. A series of tests show that this type of FDPSO is designed with automatic compensation of hulls heave motion, enormously reducing the amplitude of dry wellhead deck, and that it is benefit to deepwater production and drilling work.
