The invention relates to a polar region drilling ship with single-point mooring and auxiliary power positioning, and relates to the field of polar region drilling ship forms, a ship body is provided with a round moon pool penetrating up and down, the radius of the lower half portion of the round moon pool is larger than that of the upper half portion of the round moon pool, the lower portion of the round moon pool is provided with a space for containing a buoy, and the bottom of the buoy is connected with a plurality of anchor chains. The buoy and the ship body can be connected with a bearing, so that the ship body can rotate around the circle center of the buoy. A single-point mooring system is used for replacing half of a propeller of a dynamic positioning system, and half of fuel oil can be saved theoretically compared with an existing dynamic positioning polar region drilling ship; the single-point mooring system can enable the polar region drilling ship to automatically optimize the minimum load heading angle through the weather vane effect, and the positioning capacity of the ship in the polar region ice load environment is improved.
本发明涉及一种单点系泊辅助动力定位的极地钻井船,涉及极地钻井船船型的领域,其船体设有贯通上下的圆形月池,圆形月池的下半部分半径大于上半部分半径,圆形月池下部分设有容纳浮筒的空间,浮筒底部连接有若干根锚链,浮筒可与船体连接有轴承,以使船体可绕浮筒的圆心作旋转运动。通过单点系泊系统代替动力定位系统一半推进器,相对现有动力定位极地钻井船理论上可以节省一半的燃油;单点系泊系统可以通过“风标效应”,使得极地钻井船自动寻优最小载荷艏向角,提高船舶在极地冰载荷环境下的定位能力。
