随着海洋石油工程装备制造技术的快速发展，模块化建造已成为海工装备制造的主要模式。然而，在模块结构件总装合龙过程中，对接构件的累计尺寸误差往往造成返修、返工，增加了额外的生产成本。针对火炬臂等大型结构件在总装阶段的精度控制问题，首次将精度管理技术应用于火炬臂总装过程，通过全站仪测量和Eco-Block、Eco-OTS精度分析软件，实现了火炬臂与挂钩的模拟搭载分析。研究结果表明，该技术能够有效预测和控制火炬臂就位误差，提升总装效率，节约经济成本32.36万元，为海工模块精度管理提供了新的技术路径。

With the rapid development of offshore oil engineering equipment manufacturing technology， modular construction has become the primary mode of equipment manufacturing. However， during the assembly and closure process of modular structural components， cumulative dimensional errors of the connecting components often lead to rework and repair， causing additional production costs. This study focuses on the precision control issues of large structural components such as flare booms during the assembly stage. For the first time， precision management technology has been applied to the assembly process of the flare boom. Through total station measurement and Eco-Block and Eco-OTS accuracy analysis software， we conducted a simulated loading analysis of the flare boom and hook. The research results show that this technology can effectively predict and control the positioning errors of the flare boom， improve assembly efficiency， and reduce economic costs of 323600 RMB， providing a new technical path for offshore modular accuracy management.
