Strengthening ship and marine materials Basic research on (including technology)

"One generation of materials, one generation of equipment". The development of materials science is the basis for the development of ships and ocean engineering, and high-performance materials are the basis for advanced marine engineering. The basic guarantee for the development of engineering and high-tech ships. However, my country's current basic research on shipbuilding and marine materials is insufficient, and the top-level design of materials in the early planning stage of major projects is insufficient to meet the transformation and upgrading of the shipbuilding and marine industry. In this regard, Wang Qihong, deputy to the National People's Congress, deputy secretary of the party committee and director of the 725th Institute of China State Shipbuilding Corporation, suggested that the future development and transformation of the shipbuilding industry and the urgent needs of major technical equipment should be the main direction, and that attention should be paid to the foundation of shipbuilding materials (including technology) conduct research, strengthen stable support for basic research, focus on assessing the actual effectiveness of applications, give full play to the role of the baton, and promote the demonstration application of ship and marine materials.

Our country is the world’s largest shipbuilding country, with three major shipbuilding indicators leading the world. However, in the development process of the shipbuilding industry, the development of high-end shipbuilding supporting industries is insufficient, especially the lack of support for new material technology. For example, at present, my country's ship and marine engineering material system technology system has basically formed, and it can basically achieve self-sufficiency in general offshore engineering equipment and mainstream ship type material support, but in liquefied natural gas (LNG) carriers, large cruise ships, polar science and technology There is still a gap in basic research on high value-added ship types such as shipbuilding and advanced materials under extreme working conditions. Key materials and technologies are mainly in the hands of developed countries, mainly Europe, the United States, Japan and South Korea, which affects the international development of my country's shipbuilding industry. competitiveness.

The development and progress of basic technologies for ships and marine materials is an important guarantee for realizing the national strategy of becoming a strong shipbuilding and maritime power. In view of the existing problems in the current basic research on ship and sea materials, Wang Qihong suggested that we should strengthen the top-level demonstration of ship and sea materials for major equipment, arrange material pilot projects in advance, solve the basic research problems of new materials, improve the basic technical reserves, and achieve larger-scale use as soon as possible. , gradually replace traditional metal materials with new materials, and then lead the revolutionary progress of ship and sea equipment; it is necessary to guide various social forces to focus on the strategy of maritime power, pay attention to the research and application of new ship and sea materials, and effectively focus on marine equipment and major ship and sea equipment Construction urgently needs new materials, mobilize the enthusiasm of many parties, propose new solutions with new materials, and support the construction of a strong shipbuilding and maritime power; in the process of transformation and upgrading of China's shipbuilding industry, it is necessary to strengthen the research and application of new shipbuilding materials, with advanced The application of new materials represented by composite materials leads the progress and transformation of the shipbuilding industry, thereby achieving new quality productivity, promoting industry progress, activating industrial momentum, and creating a new era of my country's maritime economy.important growth point.

Strengthening basic research in the field of deep-sea equipment

"Although our country has initially built a series of equipment including manned and unmanned submersibles, Some technologies of the deep-sea equipment system have reached the international leading level, but due to its late start, the foundation of deep-sea equipment research is still weak. Especially in deep-sea navigation and communications, there is still a need to develop high-precision detection equipment. "At this year's National Two Sessions, the country said. Hu Zhen, a member of the Chinese People's Political Consultative Conference and a researcher at China State Shipbuilding Corporation's 702 Research Institute, said that while building a strong equipment pedigree for my country's deep-sea equipment, it is urgent to strengthen basic research. It is recommended to increase investment in marine science and technology and strengthen the connection between basic research and technology research and development task deployment. , to ensure the long-term development of my country's deep-sea equipment industry.

In the past two decades, my country's deep-sea equipment technology has made significant breakthroughs. Following the "Jiaolong" and the "Deep-Sea Warrior", the "Struggle" full-sea deep manned diving The vehicle successfully achieved a 10,000-meter dive. At the same time, the "Wukong" AUV and the "Haidou-1" ARV also completed a 10,000-meter deep dive mission. These achievements mark that my country's deep-sea equipment has officially entered the international leading ranks. By developing a series of 10,000-meter submersibles, my country has made comprehensive breakthroughs in key technologies in the full-depth field of the ocean, covering ultra-large diving depth design, new titanium alloy materials and processing techniques, high-strength buoyancy materials, oil-filled lithium batteries, propulsion equipment, deep-sea hydraulics, ultra-high-pressure seawater pumps, operating manipulators, hydroacoustic communication and positioning, submersible control, and emergency safety. Combined with the technical achievements of the "Jiaolong", the "Deep Sea Warrior" and a group of unmanned submersibles, this marks the arrival of the era of independent research and development of deep-sea equipment in our country.

　"Although key technological breakthroughs have been made in the research and development of deep-sea equipment, original innovation results are still insufficient. This is mainly due to the fact that my country's basic research in the deep-sea field is relatively weak and lacks systematic The accumulation of theories, basic materials and principles. "Hu Zhen believes that when developing new concepts and new principle equipment, the lack of necessary basic technical support increases the difficulty of developing more advanced equipment. In the past two decades, our country has successfully developed deep-sea equipment such as manned submersibles, autonomous unmanned submersibles, underwater gliders, and cable-controlled submersibles.It is equipped with a diving depth of 10,000 meters. A large amount of application technology, operational data and research and development results have been accumulated during the research and development of these cutting-edge equipment. In order to promote the sustainable development of my country's deep-sea equipment technology, we need to systematically sort out and trace these results, clarify basic research directions, and conduct in-depth related research to consolidate the foundation of deep-sea equipment research and development and lay a solid technical foundation for my country to lead the development of deep-sea equipment technology. .

Hu Zhen proposed six basic research directions through a systematic review of my country's deep-sea equipment field, including the overall direction of deep-sea equipment, material direction, communication and navigation direction, power and energy direction, and environmental perception. Direction and control of technical direction. Through long-term and stable support in these directions, the leapfrog development of original innovation can be promoted.

In order to strengthen basic research in the field of deep-sea equipment and ensure my country's continued leadership in deep-sea science and technology, Hu Zhen suggested that first, increase investment in marine science and technology, optimize the proportion of basic research investment, and provide a solid foundation for the development of marine science and technology. Sustainable development provides sufficient motivation.

Secondly, strengthen the connection between basic research and technology research and development task deployment. my country's science and technology field is in a critical period of rapid development. It requires science and technology planning departments, scientific research management departments and scientific research units to strengthen cooperation to jointly promote the good and upward development of scientific and technological levels. He called on relevant departments to further strengthen top-level planning to ensure an overall layout among basic research, technology research and development and application demonstration.

Finally, optimize scientific research management and help basic research advance in an orderly manner. In view of the relatively weak basic research in my country's marine field, it is recommended to organize experts from the perspective of scientific research management to demonstrate the front-end basic research needs of technology research and development, optimize the review and audit process, provide continuous support for identifying valuable research directions, and effectively alleviate the problem. burden on scientific researchers, ensure the stability of the basic research team, and promote the orderly advancement of basic research through institutional innovation.
