The invention relates to a rotatable drill floor and drilling ship structure, and belongs to the technical field of ocean engineering, the rotatable drill floor and drilling ship structure comprises a main ship body, a drill floor support arranged on the main ship body, a winch arranged on the main ship body and located on the periphery of the drill floor support, a drill floor arranged on the drill floor support and a derrick arranged on the drill floor, the multiple drill floor supports are evenly distributed on the periphery of the upper portion of the moon pool hole, and the winch can drive the drill floor supports to rotate on the main ship body around the axis of the moon pool hole and/or fix and bind the drill floor supports. The drill floor can slide and rotate on the deck of the ship body, when the angle of the bow is adjusted along with the sea wave direction, the drill floor can rotate in the opposite direction, it is guaranteed that various pipelines are not wound, the positioning precision of a dynamic positioning system is guaranteed, the ship is not affected by sea wave changes, and then the drilling operation efficiency is improved.
本发明涉及一种可旋转式钻台与钻井船结构,属于海洋工程技术领域,其包括主船体、设于主船体上的钻台支架、设于主船体上且位于钻台支架外周的绞车、设于钻台支架上的钻台、以及设于钻台上的井架,主船体开设有月池开孔,钻台支架设为多个且均布于月池开孔上方外周,绞车可驱动钻台支架围绕月池开孔轴线在主船体上旋转和/或对钻台支架进行固定绑扎。本发明中钻台在船体甲板上可滑动旋转,当船头随海浪方向调整角度时,钻台可反方向旋转,确保各种管线不被缠绕,保证动力定位系统的定位精度,使船不受海浪变化影响,进而提高钻井作业效率。
