一种连续竖向管件装卸及提升浮力结构,其具有:船体;主甲板;上颈部,该上颈部从主甲板向下延伸;上截锥形侧部段;中间颈部;下颈部,该下颈部从中间颈部延伸;椭球形龙骨;以及鳍形附件,该鳍形附件紧固至椭球形龙骨的外部的位于下部且位于外部的部分。上截锥形侧部段位于上颈部下方,并且上截锥形侧部段对于浮力结构的运输深度被保持在吃水线上方并且对于浮力结构的作业深度被部分保持在吃水线下方。安装至船体的自动化架创建系统与控制器通信,并且构造成组装海洋立管、组装套管以及组装钻管。
A continuous vertical tubular handling and hoisting buoyant structure has a hull, a main deck, an upper neck extending downwardly from the main deck, an upper frustoconical side section, an intermediate neck, a lower neck that extends from the intermediate neck, an ellipsoidal keel and a fin-shaped appendage secured to a lower and an outer portion of the exterior of the ellipsoid keel. The upper frustoconical side section is located below the upper neck and maintained to be above a water line for a transport depth and partially below the water line for an operational depth of the buoyant structure. An automated stand building system mounted to the hull is in communication with a controller and configured to make up the marine risers, make up casing, and make up drill pipe.
