Recently, China Shipbuilding Industry Corporation held a national high-tech and excellent ship project - the key project of passenger rolling ship, the project of "1300 passengers / 1800m lane passenger rolling ship development" appraisal meeting, the experts agreed that "Bohai Jinzhu The successful manufacture of the "Bohai Silver Pearl" wheel has filled a number of gaps in domestic ship design and manufacturing technology, and achieved a major breakthrough in ship design and manufacture, marking the level of international passenger ship construction and passenger rolling transportation reached the international advanced level. .
According to the appraisal committee, the main innovations of the project are:
——The development unit has independently developed the wave resistance, rapidity and stability through the comprehensive technology of hull linearity and propeller optimization design, fin stabilizer configuration and double head thruster for the meteorological and sea conditions of the Bohai Bay. New ship type with good maneuverability, especially in 8th grade wind and 5th grade sea state, the roll angle does not exceed 3 degrees. The design state achieved zero ballast and the effective loading factor increased from around 0.3 to 0.49.
—— Breaking through the key technologies of passenger ship overall layout and cabin definition, solving the technical problems of passenger evacuation and passenger diversion, defining the vehicle area as a ro-ro space, designed as a closed area, and adopting for the first time on the Bohai Bay passenger ship. The fixed CO2 fire extinguishing system, this design breakthrough has greatly improved the safety of the passenger rolling ship, and the technology has been promoted and applied.
——The first proposed tie rod-tilt structure changed the traditional design method of structural stress analysis. The three-deck deck of the building was considered as a whole with the main deck, and the characteristics of the passenger rolling cabin layout were skillfully broken. The difficulty in the structural design of the large-span of the passenger rolling ship effectively controls the center of gravity of the structure and maximizes the use of the cabin space to meet the requirements of ro-ro work, cabin layout and load capacity.
——In response to the special requirements of the safety of the Bohai Bay, the equipment system configuration was optimized, and technical problems such as vehicle cabin ventilation, passenger vehicles and channel equipment optimization integration were solved. The remote video surveillance system is used to monitor the navigation status of the ship at the ship base.
——Adopting a number of new technologies and new processes to ensure the quality of the first installation and installation of the channel equipment in China, and to ensure the watertight performance between the hood and the hull structure interface. A large number of new fire-resistant lightweight materials have been used, and the interior of the ship has achieved perfect results through careful construction. The flat-layer deck dressing is used to control the thickness of the dressing and is beautiful and durable.
The appraisal committee believes that the ship has achieved a number of patent achievements in the development of the ship type. It is the first large-scale passenger rolling ship with a full independent intellectual property rights of more than 150 meters in the country, which fills a lot of blanks in domestic design and manufacturing technology. And the operation certificate, this type of ship is a high-tech, high-value-added ship with safe protection, excellent performance and advanced equipment in the Bohai Bay. The main performance indicators of this type of ship have reached the international advanced level, and some of the technologies have reached The international leading level is of great significance to promoting the development of passenger rolling boats in China. It is recommended that this type of ship be recommended to the Ministry of Communications as a standard ship type promotion application.
