由于海洋工程的制造工艺要求，高空作业非常普遍，尤其在模块和导管架等大型结构物的组装阶段，高空作业和多层交叉作业的频率及可坠落高度不断增加。通过对目前国内外在高处作业安全方面的研究进行分类综述，系统探讨了高处作业的定义、辨识标准，并参考国内外法规标准和工程实践，提出了综合性的预防措施，涵盖工程技术、管理、人员、物理防护等多方面。为确保脚手架的安全性，探讨了不同的脚手架型式和建造施工过程中的选型，旨在提供适用于海洋工程制造业的高处作业安全管理框架，从而有效降低事故率，保障作业安全。

Due to the specific manufacturing processes in offshore engineering， work at height is highly prevalent， particularly during the assembly phases of large structures such as modules and jackets， where the frequency of work at height and multi-level crossover operations， as well as the potential fall height， are continuously increasing. This paper provides a classified review of current domestic and international research on work-at-height safety. It systematically examines the definition and identification criteria of work at height and proposes comprehensive preventive measures based on domestic and international regulatory standards and engineering practices. These measures encompass multiple aspects， including engineering technology， management， personnel， and physical protection. To ensure the inherent safety of scaffolding， the paper discusses different types of scaffolding and their selection during construction， aiming to provide a safety management framework for work at height in the offshore engineering manufacturing industry. This framework is designed to effectively reduce accident rates and ensure operational safety.
