Gravity-based foundation for offshore installations
The patent US12006648B2 outlines a method for manufacturing a gravity-based foundation specifically designed for offshore installations, such as wind energy systems. The foundation consists of a concrete caisson featuring a bottom slab, a roof, and a side wall that together create a hollow structure. A hollow shaft extends through the roof into the caisson, supported by a concrete shaft support that includes tensioning bars. The method involves several steps, including the provision of full-length and slip formworks to shape the shaft support and side wall, respectively, and the pouring of concrete into the defined spaces. The design allows for the integration of partition walls within the caisson, enhancing structural integrity.
Additionally, the method incorporates various reinforcement techniques, such as the use of rebar for the bottom slab, side wall, and partition walls. The tensioning bars are strategically positioned to ensure stability and support for the shaft, which is connected to a wind turbine. The foundation is designed to be self-buoyant, facilitating its deployment in offshore environments. The patent also covers the resulting gravity-based foundation and its application in offshore wind energy installations, highlighting the innovative construction techniques and structural features that contribute to the foundation's effectiveness and durability.
