A semi-submersible drilling vessel has a deckbox structure, one or more pontoons, and multiple support columns extending upward from the one or more pontoons and supporting thereon the deckbox structure. An annular riser joints storage caisson extends downwardly from the deckbox structure, wherein the storage caisson delimits an annular storage space configured for storage therein of an annular array of riser joints in vertical orientation thereof. A riser joints carousel device is provided in the annular storage space, which riser joints carousel device is configured to carry an annular arrayof riser joints in vertical orientation thereof in a mobile manner relative to the annular storage caisson so that the array of riser joints is movable along an annular path through the storage spaced between the inner and outer wall of the storage caisson. The deckbox structure is provided with a riser joint transfer passage at a riser joint transfer location above the annular path of the riserjoints carried by the riser joints carousel device through the storage space. The vessel is provided with a riser joint vertical transfer device configured to lift and lower a riser joint out of and into the riser joints carousel device, passing therein vertically through the riser joint transfer passage of the deckbox structure.

    一种半潜式钻井船,其具有甲板箱结构、一个或多个浮箱、以及从一个或多个浮箱向上延伸并在其上支撑甲板箱结构的多个支撑柱。环形立管单根存储沉箱从甲板箱结构向下延伸,其中,存储沉箱界定了环形存储空间,该环形存储空间配置为用于沿着立管单根的竖直方向在其中存储环形阵列的立管单根。立管单根转盘装置设置在环形存储空间中,所述立管单根转盘装置配置为相对于环形存储沉箱以移动的方式在立管单根的竖直方向上承载所述环形阵列的立管单根,使得所述阵列的立管单根沿着穿过位于存储沉箱的内壁与外壁之间的存储空间的环形路径可移动。甲板箱结构在由立管单根转盘装置承载的立管单根的穿过存储空间的环形路径上方的立管单根运送位置处设置有立管单根运送通道。船设置有立管单根竖直运送装置,该立管单根竖直运送装置配置为使立管单根提升出和降入立管单根转盘装置,从而在其中竖直地穿过甲板箱结构的立管单根运送通道。
