A drilling rig arrangement for use in a floating drilling platform is described having a hull, a main deck, an upper cylindrical side extending downwardly from the main deck, an upper frustoconical side, a cylindrical neck, a lower elliptical portion extending from the cylindrical neck, and a lower outer side of a bottom surface. And a fin-shaped accessory fixed on the part is arranged. The upper frustoconical side is located below the upper cylindrical side and remains above the waterline for the bearing depth of the floating drill and is also partially below the waterline for the working depth of the floating drill.
本发明描述了一种浮式钻井平台使用的钻机装置,具有船体、主甲板、从主甲板向下延伸的上部圆柱形侧部、上部截头圆锥形侧部、圆柱形颈部、从圆柱形颈部延伸的下部椭圆形部分以及底面的下部外侧。有一个固定在零件上的鳍状附件。上部截头圆锥形侧部位于上部圆柱形侧部的下方,并且对于浮式钻机的承载深度而言保持在水线上方,并且对于浮式钻机的工作深度而言也部分低于水线。
