深水FPSO吸力锚建造工艺

Construction process of deep water FPSO suction anchor

以某深水浮式生产储卸油装置(FPSO)的吸力锚建造为例,对吸力锚的钢制筒体、顶盖结构、内部切泥板、铸造吊耳及锚链等主要结构预制安装流程与吸力锚整体装船工艺进行阐述。研究结果表明:深水FPSO吸力锚在建造过程中通过制定合理的施工顺序、严格控制组对尺寸公差和焊接参数等措施,对整个项目的质量管控和工效提升至关重要,也为后期同类大型管状结构物的建造提供了有益的参考。

This article takes the construction of a suction anchor for a deep-water floating production storage and unloading unit(FPSO)as an example,and elaborates on the prefabrication and installation process of the main structures of the suction anchor,including the steel cylinder,top cover structure,internal mud cutting plate,casting lifting ears,anchor chains,and the overall loading process of the suction anchor.The research results indicate that during the construction process of deep-water FPSO suction anchors,it is crucial to establish a reasonable construction sequence,strictly control the dimensional tolerances and welding process parameters of the assembly,and improve the quality control and efficiency of the entire project.It also provides useful reference for the construction of similar large tubular structures in the later stage.
