Abstract: In view of the problem that the hoisting scheme in the construction process of inland ships depends on field experience and lacks of theoretical data support, two different hoisting implementation schemes of total hoisting reinforcement and sub section hoisting reinforcement were proposed. According to the actual construction data, the subsection model of ship large superstructure was established by using the finite element software, and the load distribution characteristics and relevant safety requirements during hoisting were determined by using mechanical theory and referring to relevant literature. Finally, the hoisting process under different schemes was simulated and calculated. The simulation results show that although the total section hoisting scheme can save hoisting time, it has higher requirements for the strength of section structure, higher requirements for hoisting tools on the construction site and greater potential safety hazards. Although the sub segment hoisting scheme requires multiple hoisting, it has lower requirements for on-site hoisting tools, and the hoisting scheme is more flexible and more suitable for the needs of inland ship builders at this stage. Construction example feedback also confirms that the use of sub segment hoisting scheme can greatly eliminate the safety hazards in the hoisting process and has certain advantages in improving the construction quality.
