The installation of the propulsion module is the last step in the installation of the pod propulsor. Aiming at propulsion module installation difficulties of the pod propulsor on the first domestic large cruise ship, a special installation platform for the propulsion module was developed after studying the installation characteristics of the propulsion module, the installation methods taken by foreign shipyards for similar products, the construction environment and installation experience of the shipyard. The complex three-dimensional space positioning problem is decomposed into several simple two-dimensional space actions to achieve independent adjustment of single degree of freedom. The installation platform has a high degree of automation and precision control, and it’s easy to operate. Through the application of the installation platform, the installation efficiency has been improved by leaps and strides, which has an active role in promoting the efficient construction of high value-added ships such as cruise ships.
