Core Viewpoint - The successful floating of China's second domestically produced large cruise ship "Aida Huacheng" (H1509) marks a significant milestone in the shipbuilding process, laying a solid foundation for its completion and delivery by the end of 2026 [1][2]. Group 1: Construction Progress - The floating process is a critical milestone in the construction of large cruise ships, aimed at determining key technical indicators such as weight center and releasing residual stress [1]. - The H1509 ship's construction time from docking to first floating was shortened by one month compared to the first domestic large cruise ship "Aida Modu" [2]. - The overall project work hours were reduced by 20%, with 57.2% of actual working hours achieving over 70% of the project's overall progress, representing a 12% improvement compared to the first ship [2]. Group 2: Technical Enhancements - The H1509 ship has seen a significant increase in floating weight by 3,654 tons, reflecting improved construction efficiency and integrity compared to the first ship [2]. - The total tonnage of H1509 increased by 0.64 million tons to 141,900 tons, with a total length increase of 17.4 meters to 341 meters [3]. - The areas for public and outdoor recreational activities have expanded to 25,599 square meters and 14,272 square meters, respectively [3]. Group 3: Management and Innovation - The company emphasizes a management philosophy of "learning, exploring, summarizing, and innovating," which has led to comprehensive reflections and innovations based on the construction of the first large cruise ship [2]. - A series of research achievements and management experiences have been leveraged to optimize processes and tackle technical challenges, enhancing the construction efficiency and quality of the H1509 ship [2][3]. - The construction process of H1509 has benefited from the experience gained from the first ship, leading to smoother operations and the development of digital management tools across eight areas, including design, procurement, and logistics [3].
