Abstract: 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.

Key words: construction project, hull, afloating or resting on blocks, operation safety, safety management
