Based on the successful experience of superstructure integrity design and construction, the ship superstructure integrity design and construction technology is studied. Each shipyard can conduct the superstructure planning, design and construction according to its own hardware conditions and equipment and facilities, and continuously improve on the basis of integrity level evaluation to continuously raise the integrity delivery level of superstructure intermediate products, so as to enhance the production efficiency of ship construction. The research provides technical guidance to each shipyard in conducting the process reengineering and realizing the superstructure integrity design and construction.
