Current situation and problems of scientific and technological capability and industrial structure of Marine carrying equipment in China

(5) Power and supporting electromechanical fields

Driven by the market, the scale of China's power and supporting mechanical and electrical industry has expanded rapidly, and there are more than 500 Marine supporting equipment manufacturing enterprises above the national scale; A system of power mechanical and electrical equipment manufacturing and testing and verification facilities has been basically established, forming a relatively complete industrial chain, with products covering power systems, deck machinery, cabin machinery, automation, outfitting and other fields; In terms of processing, manufacturing and production capacity, it has reached the world's advanced level, and basically has the ability to support the power and mechanical and electrical equipment of the three mainstream ship types.

China's problems in the field of power and supporting mechanical and electrical equipment are mainly: some self-designed and manufactured power and mechanical and electrical equipment lack reliability indicators, and products have not yet formed a series, standardization, brand loading rate is low; The development of power supporting equipment services is slow, and there is a big gap with European enterprises in the number of service outlets, service efficiency, and service coverage.

Second, the key development direction of China's Marine carrying equipment

China's Marine transport equipment field urgently needs to make up for the shortcomings of the industrial chain, implement key technology research, constantly improve the green and intelligent level of Marine transport equipment, improve construction efficiency and quality, and accelerate the cultivation of core key systems and equipment with independent intellectual property rights. The formation of a sound Marine transport equipment research and development design, assembly and construction, equipment supply, technical service industry system and standardization system, to promote the Marine transport equipment industry development mode into a scientific and technological innovation driven.
