The invention discloses a hollow cylindrical floating oil production, storage and offloading device which is composed of a lower floating body, an upper module and a mooring rope, the lower floating body comprises a main deck, the upper module is arranged on the main deck, and the mooring rope is arranged on the upper module. An outer floating deck box, an upper hollow annular cylindrical barrel, a circular-truncated-cone-shaped transition section, a lower hollow annular cylindrical barrel and a heaving body are sequentially arranged on the side, away from the upper module, of the main deck so that the lower floating body can be arranged in a cylindrical shape. A mooring cable is connected to the lower floating body, the near end of the mooring cable is fixed to the heaving body through an anchoring groove, and the far end of the mooring cable is fixed to the seabed; the upper module is connected with a steel catenary vertical pipe, and the steel catenary vertical pipe penetrates through the lower floating body to be connected with a seabed wellhead. According to the hollow cylindrical floating type oil production, storage and unloading device, the large-size moon pool penetrating up and down is arranged in the lower floating body, so that the waterline area of in-place design draft of the platform is effectively reduced, the heaving natural period of the platform is prolonged, and the main energy period range of waves is avoided.

    本发明公开了一种中空圆筒形浮式生产储卸油装置,该中空圆筒形浮式生产储卸油装置由下浮体、上部组块和系泊缆组成,下浮体包括主甲板,主甲板上设置有上部组块,主甲板远离上部组块一侧依次设有外漂甲板箱、上中空环柱形筒体、圆台形过渡段、下中空环柱形筒体和垂荡体,以使下浮体呈圆筒形设置;下浮体上连接有系泊缆,系泊缆近端通过锚系开槽固定在垂荡体上,系泊缆远端固定在海底;上部组块连接有钢质悬链线立管,钢质悬链线立管穿过下浮体与海底井口连接。本发明提供的中空圆筒形浮式生产储卸油装置通过在下浮体内设置上下贯通的大尺寸月池,有效减小平台在位设计吃水的水线面面积,提高了平台垂荡固有周期而避开波浪主能量周期范围。
