摘　　要：在大型海工建造项目中,船体坞内起浮坐墩作业是一个重大施工环节。由于坞内起浮坐墩作业同时涉及到多种高风险作业的联合施工,加上船坞内面积狭小,水下环境复杂,新建造船体不可控因素较多,在海工建造领域,船体坞内起浮坐墩作业的安全受到项目方的格外重视。以国内某大型海工建造项目为例,对起浮坐墩安全与应急研究的必要性进行了探讨,研究了船体坞内起浮坐墩作业过程中安全管理的策略,对起浮坐墩前的组织准备、生产物资准备和状态确认、船舶起浮坐墩的实施和收尾等环节的关键内容进行了阐述,同时探究了作业过程中的应急管理相关内容,以进一步完善船体坞内起浮坐墩作业常规安全与紧急情况的应急环节,形成完整的安全管理闭环,防止因安全工作不到位而损坏船体、影响坞期或造成事故,为大型海工建造项目起浮坐墩作业安全提供借鉴思路。In large-scale offshore construction projects,the afloating or resting on blocks in the hull dock is an important construction link.Due to the joint construction of a variety of high-risk operations,the small area of the dock,the complex underwater environment,and many uncontrollable factors of newly built hulls,the safety of the afloating or resting on blocks in the dock has been paid special attention by the project side for a long time in the field of offshore construction.Taking a large offshore construction project in China as an example,this paper discusses the necessity of safety and emergency research on the afloating or resting on blocks,studies the safety management strategy in the process of the afloating or resting on blocks in the hull dock,and expounds the key contents of the organization preparation,the production materials preparation and the status confirmation before the afloating or resting on blocks,the implementation and finishing of the ship’s afloating or resting on blocks.At the same time,the relevant contents of emergency management in the process of operation are explored,so as to further improve the routine safety and emergency links in the process of safety management of afloating or resting on blocks in the hull dock,and form a complete closed loop of safety management,so as to prevent damage to the hull,affect the dock period or cause accidents due to inadequate safety work.This paper provides some reference ideas for the safety of afloating or resting on blocks in our large-scale offshore construction projects.
