摘　　要：从一种新型浮式钻井生产储油装卸系统(FDPSO)的概念设计出发,针对干式井口甲板垂直方向的相对运动问题,建立了系统的简化理论模型,运用半物理仿真的方法搭建了实验平台,根据船体的垂荡响应谱确定简谐激励的实验工况,实验和数值结果相吻合,系列实验结果表明这种FDPSO的设计对船体的垂荡运动具有自动补偿作用,减小了干式井口甲板的运动振幅。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.
