Among the installation of many modules of the pod propulsor, the steering module installation is the most important, and its installation accuracy has a direct impact on the subsequent installation of other modules in the future. The installation of ABB Azipod XO type, 16.8MW large electric powered pod propulsor steering module for the first domestic large cruise ship is divided into six steps: pre-lifting preparation, structural measurement and cutting, lifting and positioning, pre-welding assembly, welding and monitoring, post-welding work. Through the research on the work of each step, it is found that the installation work has complex procedures and strict order requirements. Precision control is carried out throughout the installation process and is closely related to the installation procedure and sequence. Through the study, it is also found that the installation efficiency can be improved and the installation cycle shortened by moving the installation stage to the section stage and the automatic welding to be used for regular welding.
