Abstract: Economic globalization has driven the development of China’s manufacturing industry. The rise of major clean energy projects such as offshore wind power has increased the demand for maritime transportation of super-large structures. In view of the problems of poor universality, cumbersome procedures, and high cost faced by the current lashing tools for super-heavy marine modules such as offshore wind power jackets during sea transport, this paper designs a new gantry-type lashing tooling and systematically evaluates its strength and deformation through finite element analysis. The results show that when transporting a typical wind power jacket module, the maximum stress and deformation of the tooling are 236.62 MPa and 2.15 mm, respectively; when transporting an offshore pile module, the values are 110.85 MPa and 1.80 mm, respectively. Both are below the allowable stress of Q355B steel (273.08 MPa). The tooling has reliable strength, strong versatility, and high reusability. It can significantly shorten the lashing preparation cycle for major components such as wind power jackets, reduce the comprehensive transportation cost, and provide a feasible solution for cost reduction and efficiency improvement in the maritime transport of major components within the offshore wind power industry chain.

摘要： 经济全球化推动了我国制造业发展,海上风电等清洁能源重大工程的兴起,带动了超大型结构物海上运输的需求。针对当前海上风电导管架等超重型海工模块在海运绑扎作业中,所用工装通用性差、流程繁琐、成本高昂等难题,该文设计了一种新型门架式绑扎工装,并通过有限元分析系统评估了其强度和变形。研究结果表明：运送典型风电导管架模块时,工装最大应力及变形分别为236.62 MPa、2.15 mm;运送海桩模块时,工装最大应力及变形分别为110.85 MPa、1.80 mm,均低于Q355B钢材许用应力（273.08 MPa）。该工装强度可靠、通用性强、重复利用率高,可显著缩短风电导管架等重大件的绑扎准备周期,降低综合运输成本,为海上风电产业链重大件的海运降本增效提供了可行方案。
