Ultra-large FPSO pipe gallery module construction process
The invention discloses an ultra-large FPSO pipe gallery module construction process. The process comprises the following steps of dividing a pipe gallery module into an upper section and a lower section, prefabricating the upper section and the lower section, prefabricating a cup support, and welding and fixing the cup support and the lower section; performing sand blasting and coating on the upper section and the lower section of the pipe gallery module; hoisting and transporting the upper section of the pipe gallery module to a final assembly position, and transporting the lower section to the final assembly position by using an overhanging type transportation assisting frame and an SPMT; and enabling the upper section and the lower section of the pipe gallery module to be subjected to final assembly. The strength of a fragmentation structure of a fragmentation mode is higher than that of a traditional single-layer fragmentation structure, so that the deformation control of the upper section and the lower section during hoisting and transportation is facilitated; meanwhile, only one-time stand column butt joint is needed, so that the number of times of final assembly of stand columns is reduced, and the perpendicularity of the stand columns is effectively guaranteed; and compared with a traditional process, the construction process has the advantages that a large number of prefabrication, transportation, hoisting and spraying resources do not need to be occupied, the work efficiency is greatly improved, the transportation problem of the pipe gallery module is solved, and the project cost is reduced.
本发明公开了一种超大型FPSO管廊模块建造工艺，包括步骤：将管廊模块分为上分段和下分段分别进行预制，并预制垫墩，将垫墩与下分段焊接固定；将管廊模块的上分段和下分段进行喷砂涂装；吊装运输管廊模块的上分段至总装位置，使用外伸式运输辅助框架和SPMT运输下分段至总装位置；将管廊模块的上分段和下分段总装；本发明采用的分片方式的分片结构强度要强于传统单层分片结构强度，有利于上分段和下分段在吊装和运输时的变形控制，同时仅需一次立柱对接，降低了立柱总装组对的次数，有效地保证了立柱的垂直度，相比较于传统工艺，本发明不需要占用大量预制、运输、吊装和喷涂资源，大幅度提高了工效，解决了管廊模块运输问题，降低了项目成本。
