Abstract: The present disclosure provides a system and a method for efficiently converting the structure of a drilling floating platform into a structure for a production floating platform. A riser support module can be coupled to a topsides of the drilling floating platform and suspended below a moonpool or other opening through the topsides to support risers and their respective riser pull tubes, if any. The riser support module can be prebuilt and installed as a unit for example at a quayside.

Abstract: A floating offshore platform is disclosed with one or more extension plates fixedly coupled to one or more pontoons on the offshore platform and extending from the pontoons. As the floating platform moves, the pontoon-coupled extension plates separate the water and cause drag on the platform. The water moving with the extension plates also increases the dynamic mass. The added drag and dynamic mass increases the natural period of the motion away from the wave excitation period to minimize the wave driven motion compared to a platform without the extension plates. The extension plates can be coupled to the pontoons during fabrication at the yard directly or through frame members. The extension plates generally are generally located inclusively between the top and bottom elevations of the pontoons, and therefore do not significantly reduce the clearance between the seabed and the hull at the quayside.

Abstract translation: 公开了一种浮动海上平台，其中一个或多个延伸板固定地联接到海上平台上的一个或多个浮筒并从浮筒延伸。 当浮动平台移动时，浮桥连接的延伸板将水分离并在平台上引起拖动。 用延伸板移动的水也增加了动态质量。 与没有延伸板的平台相比，增加的阻力和动态质量增加了运动远离波浪激发周期的自然周期，以最小化波动驱动运动。 在制造期间，延伸板可以直接地或通过框架构件连接到浮筒。 延伸板通常通常位于浮筒的顶部和底部高度之间，因此不会显着地减少在码头区域的海床和船体之间的间隙。
