依托欧洲某海上风电项目，针对传统导管架设计模式操作烦琐、效率低、误差率高的问题，本文深入研究建筑信息模型（BIM）核心软件Tekla的设计应用价值，旨在提升设计质量与效率，为项目高效实施提供技术支撑。文中先详细介绍Tekla三维实体建模技术在该项目的应用流程与技术优势，再以导管架主结构建模为例，构建线模型、制作清单模板、输出材料清单，并对比分析钢材质量数据，为采购、预制及成本控制提供可靠依据。鉴于风电导管架图纸信息丰富，CAD单件图绘制软件编制造管图效率低，研究团队利用Tekla二次开发能力，成功开发结构相贯线自动化工具插件，解决出图难题。最后，通过对比验证，证明Tekla三维模型及扩展工具能显著提升设计质量与效率，实现降本增效，为海上风电导管架工程设计提供技术与实践依据。

Based on a European offshore wind power project， addressing the issues of cumbersome operation， low efficiency， and high error rate in traditional jacket design methods， this paper delves into the design application value of the core building information modeling （BIM） software Tekla， aiming to enhance design quality and efficiency and provide technical support for the efficient implementation of the project. The paper first elaborates on the application process and technical advantages of Tekla’s 3D solid modeling technology in this project. Then， taking the main structure modeling of the jacket as an example， it constructs wireframe models， creates material list templates， outputs material lists， and compares steel weight data from different sources， providing reliable data for procurement，prefabrication， and cost control. Given the rich information required in the drawings of offshore wind power jacket foundations and the low efficiency of using CAD single-part drawing software to create pipe fabrication drawings， the research team successfully developed a structural joint geometry automation tool plugin by leveraging Tekla’s secondary development capabilities， thereby solving the drawing generation challenges. Finally， through comparative verification， it is demonstrated that Tekla’s 3D models and extended tools can significantly improve design quality and efficiency， achieve cost reduction and efficiency enhancement， and provide technical and practical foundations for the design of offshore wind power jacket engineering.
