Research on Marine carrier equipment technology and industrial development

To do a good job, we must first use its tools, and Marine carrying equipment is the "backbone" of safeguarding Marine security and sovereignty, maintaining the stable development of the Marine economy, and promoting innovative research in Marine science. Under the strategic needs of China to accelerate the construction of a Marine power, a manufacturing power, and a transportation power, it is urgent to accelerate the technological innovation and high-quality industrial development of Marine transport equipment.

Academician Wu Yousheng of the Chinese Academy of Engineering research team wrote an article in the journal of the Chinese Academy of Engineering "China Engineering Science", in view of the future development of China's Marine carrier equipment technology and industry, the development needs of the world's Marine carrier equipment were studied and judged, the current technological status and industrial pattern of the world's Marine carrier equipment were analyzed, and the advanced frontier technologies of the world's Marine carrier equipment were summarized. The paper points out that the key development direction of the Marine carrying equipment field in the near future is the breakthrough key technology in five aspects: polar navigation ship technology, ship intelligent manufacturing technology, ship optimization and energy saving technology. It is proposed to set up intelligent ship engineering, super ecological and environmental protection ship science and technology special, and ship whole life cycle operation and maintenance technology special. In order to provide reference for the competent departments of shipbuilding industry and relevant institutions of "industry-university-research and application" forward-looking layout technology research direction.

I. Introduction

The ocean is a treasure house of strategic resources for the sustainable development of mankind. Since the beginning of the 21st century, the international struggle for maritime rights and interests, characterized by competition for Marine resources, control of Marine space, and seizing the commanding heights of Marine science and technology, has become increasingly fierce. To do a good job, we must first use its tools, and Marine carrying equipment is the "backbone" of safeguarding Marine security and sovereignty, maintaining the stable development of the Marine economy, and promoting innovative research in Marine science. Under the strategic needs of China to accelerate the construction of a Marine power, a manufacturing power, and a transportation power, it is urgent to accelerate the technological innovation and high-quality industrial development of Marine transport equipment.

The technical connotation of ocean carrying equipment includes: the overall technology of various ships and ocean carrying platforms (including design, manufacturing and operation), the power technology of ocean carrying equipment, the supporting equipment technology of ocean carrying equipment, the navigation technology of ocean carrying equipment, etc., and the education and scientific research system involved in ocean carrying equipment technology and industrial pattern.

At present, the research on Marine carrier equipment technology and industrial development is mainly analyzed from the perspective of overall technology and final assembly and construction, and there are few studies on the analysis of key supporting systems and equipment and development suggestions, and the relevant studies are lack of systematical. Therefore, on the basis of visits, research, expert discussions and project research, this paper takes higher education, scientific research, overall technology and assembly construction, information and communication navigation, power and supporting mechanical and electrical equipment in this field as the entry point. To carry out research on the development needs of the world's Marine carrier equipment, the world's Marine carrier equipment technology and industry pattern, the current situation and problems of China's Marine carrier equipment development, and the key development directions and countermeasures in the field of China's Marine carrier equipment.

Second, the development needs of the world's ocean carrying equipment

(1) Market demand

In the context of uncertain global economic growth, the growth rate of global import and export trade shows a downward trend, and the global seaborne trade volume is difficult to increase significantly (see Figure 1). At present, global energy consumption is dominated by traditional energy sources such as oil and natural gas, but the growth rate of demand will gradually slow down. In the absence of extreme conditions, it is difficult for the new demand for Marine transport equipment to return to the peak demand of 2008. From the supply side, after reaching its peak in 2012, Marine carrying equipment production capacity has been in a shrinking adjustment stage affected by the market environment. According to Clarkson database statistics, by 2019, global active production capacity has fallen to about 3.5× 107 modified gross tons (cgt), and it is difficult for major shipbuilding countries to further reduce production capacity in the future. In this context, the market competition among major shipbuilding countries will become more intense.
