The invention relates to the technical field of drilling ships, and discloses a drilling ship moon pool structure which comprises a ship body and a moon pool, the moon pool is located in the center of the ship body and vertically penetrates through the ship body, the ship body is divided into a stern ship body structure and a prow ship body structure by the moon pool, the stern ship body structure is close to a stern, and the prow ship body structure is close to a prow. The inner wall of the moon pool is vertically provided with a moon pool groove in a spiral surrounding mode, and the moon pool groove in the spiral surrounding mode is formed in the moon pool, so that vortexes are generated in the moon pool when the ship body moves, an original flow field in the moon pool is changed, fluid in a moon pool cabin has large inertia momentum, and therefore the ship body can be driven to move. It is guaranteed that fluid in the moon pool can produce an immune effect on environmental loads in the sailing process of the ship, and therefore wave-making resistance and upward waves are reduced.
本发明涉及钻采船技术领域,公开了一种钻井船月池结构,包括船体和月池,所述月池位于船体中心位置并上下贯穿船体,且所述月池将船体分隔为船尾船体结构和船首船体结构,所述船尾船体结构靠近船尾,所述船首船体结构靠近船首,所述月池内壁竖直设置螺旋环绕的月池凹槽,本发明在月池内设置螺旋环绕的月池凹槽,使船体在移动时在月池内产生漩涡,从而改变了月池内部的原始流场,月池舱内的流体具有较大惯性动量,保证在船航行过程中月池内流体能够对环境载荷产生免疫作用,从而减小兴波阻力和上浪。
