摘要: A riser joint keel assembly. A tapered riser joint is connected to a larger diameter outer sleeve through a connection that allows the tapered section and outer sleeve to function as one unit. In the combined design, the outer sleeve provides the required sliding interface between the riser and the guide at the keel of the hull while also providing some of the bending compliance needed to transition from the riser supported in the hull to the riser unsupported below the hull. The tapered section also provides the remaining bending compliance needed for the transition. The connection between the tapered and sleeve sections is a forged, machined ring plate welded to the bottom end of the sleeve, which provides a base for either bolted or threaded type attachment points for the tapered riser joint below the ring plate and the internal riser joint that continues to the surface.

摘要: An improved floating circular hull construction arrangement. The hull is divided into sections by watertight flats. In each section, longitudinal stiffeners spaced around the inside of the outer shell terminate adjacent the flats and do not penetrate the flats. The longitudinal stiffeners are supported by full rings that are concentric with the center of the hull. The rings are received over the longitudinal stiffeners, extend radially inward and are laterally supported with members configured to act in tension in either axial direction and which are parallel to the longitudinal axis of the hull. Rings on the inner shell extend radially outward toward the outer shell and may be laterally supported similarly to the lateral supports of the outer shell. The flats are stiffened with angles or bulb tees curved to form concentric circles that are in turn supported with radial girders spaced around the flats and spanning between the inner and outer shells. The compartments are assembled with the circular sections in a vertical orientation to minimize self-weight distortion during erection. The completed circular sections are rotated to the horizontal to be joined to the other sections to form a complete cylinder.

摘要: An improved floating circular hull construction arrangement. The hull is divided into sections by watertight flats. The flats are stiffened with angles or bulb tees curved to form concentric circles that are in turn supported by the radial girders spaced around the flats and spanning between the inner and outer-shells. In each section, longitudinal girders spaced radially around the inside of the outer-shell terminate at the flats and attach to the flats and do not penetrate the flats. The longitudinal girders are attached to flats aligned with the locations of the radial girders that extend across the flats to the inner and outer shells. A panel stiffening arrangement on the inner circumference of the outer shell is attached to the outer shell and the longitudinal girders. Longitudinal girders spaced around the outer circumference of the inner shell extend along the length of the inner shell and are attached to the radial girders. With the inner and outer longitudinal girders connected to the radial girders, moment resisting frames are created that are arranged radially in each compartment. These frames stiffen the individual girders as well as balance the differential axial loadings in the inner shell and outer shell surfaces. The compartments are assembled with the sections in a vertical orientation to minimize self-weight distortion during erection and to provide direct access with shop cranes during assembly of the full sections. The completed sections are rotated to the horizontal to be joined to the other sections to form a complete cylinder.
摘要翻译: 改进的浮动圆形船体施工安排。 船体由水密舱单分成两段。 平板被加强,角度或灯泡三通弯曲形成同心圆,其又由围绕平面间隔开并跨越内壳和外壳之间的径向桁架支撑。 在每个部分中,围绕外壳内部径向间隔开的纵向梁在平面处终止并附接到平面上,并且不穿透平面。 纵向梁连接到与沿着平面延伸到内壳和外壳的径向桁架的位置对准的平面上。 在外壳的内圆周上的面板加强装置附接到外壳和纵向桁架。 围绕内壳的外周分隔的纵向纵梁沿着内壳的长度延伸并且连接到径向桁架上。 由于内径和外纵梁连接到径向桁架上,产生了在每个隔室中径向布置的抗力框架。 这些框架加强了各个桁材,并平衡了内壳和外壳表面的差异轴向载荷。 隔间与垂直方向的部分组装在一起,以最大限度地减少安装过程中的自重变形,并在组装整个部分期间提供与起重机的直接连接。 完成的部分旋转到水平以与其他部分接合以形成完整的圆筒。
