Mammoet –10,000 [Te] jacking systemMammoet – 10,000 [Te] 顶升系统

To compete with other companies, for instance Ale’s 5.000 [Te] jacking system, Mammoet Solution decided to do a feasibility study for a 10.000 [Te] jacking system. Four large 2.500 [Te] hydraulic cylinders are used to lift the load up to a height of 30 [m]. All the steel is grade S690 to bear the high loads and to minimize transport costs. The system will mainly be used to lift offshore jackets and can be skidded over a rail above a transport frame. The feasibility study includes detail design and optimization of weld preparations to minimize costs. The corner barrels and bracing are analysed by using FEM software to optimize the cost. Goals are to minimize weight of the entire structure, optimize fabrication and to make the structure transportable in standard 20 feet and 40 feet containers.为与其他公司（如 Ale 的 5,000 吨顶升系统）竞争，Mammoet Solutions 决定开展 10,000 吨顶升系统的可行性研究。系统采用四个 2,500 吨大型液压缸，可将荷载顶升至 30 米高度。全部钢材为 S690 等级，以承受高荷载并将运输成本降至最低。该系统主要用于顶升海上导管架，并可在运输框架上方的轨道上滑移。可行性研究包括细部设计与焊接坡口优化以降低成本；角柱筒体与撑杆使用有限元软件分析优化。目标是使整体结构重量最小化、优化制造，并使结构可用标准 20 尺与 40 尺集装箱运输。
