Research on Marine carrier equipment technology and industrial development

(3) Polar ship technology

With the increasing strategic position of the Arctic region, maritime transport in the Arctic region has attracted widespread attention, and the reduction of ice caused by global warming has also made Arctic navigation more feasible. In addition, the growing tourism and fishing industries in the polar regions have created new demands for polar ships. Polar ship hull structure design, monitoring system, emergency response system, equipment reliability under changing environment are the focus of subsequent research and development.

(4) Ship noise control technology

Ship noise may affect the health of Marine life, crew and passengers. The Ship Noise Levels Code issued by the International Maritime Organization provides a reference standard for the prevention of potentially dangerous noise levels on board ships, and provides a reference standard for an acceptable environment for crew members. In addition, the International Organization for Standardization is promoting the development of international standards for ship noise. At present, the research on ship noise generation mechanism, forecasting method and control method is still a hot spot.

(5) Advanced material technology

Materials are the basis of ocean carrying equipment. Advanced new materials make ocean carrying equipment have better performance. At present, the advanced materials in the field of Marine carrying equipment include: ultra-large container ships high-strength crack stop thick steel plate, Marine low-temperature steel and polar low-temperature materials, Marine structural acoustic composite materials, drag reduction anti-fouling coatings, composite materials and low-temperature materials.

2. Research cutting-edge technology

The cutting-edge technology of Marine carrier equipment research is mainly related to the intelligence of Marine carrier equipment, aiming to promote the intelligence of equipment and promote the safe and efficient development of the shipping industry.

(1) Intelligent ship technology

The field of intelligent ship technology mainly includes: intelligent navigation control technology, intelligent management technology of energy and power system, intelligent monitoring technology of auxiliary engine safety operation, intelligent monitoring technology of whole ship safety, intelligent monitoring technology of energy saving and environmental protection, intelligent monitoring technology of vibration and noise, intelligent cargo management technology, intelligent ship integrated information system technology.

(2) Additive manufacturing technology

Additive manufacturing technology can not only improve the design of mechanical parts, increase their efficiency and longevity, but also allow related spare parts to be produced on site in different ports around the world. This will improve the company's ability to respond to market demand, reduce maintenance time, and help improve the efficiency of ship operations. Additive manufacturing technology has been applied in the field of rapid prototyping and is gradually being integrated into traditional manufacturing industries such as automotive and aircraft manufacturing. The Navy has already begun testing the technology on some ships to assess its potential for spare parts production.

(3) Advanced sensor technology

(4) Advanced communication technology

The integration of fifth-generation mobile communications (5G), wireless Internet access (Wi-Fi), a new generation of satellites and traditional radio communication networks will make the long-distance transmission of Marine information economical and convenient. Managers or users can access audio, high-definition video, three-dimensional (3D) video in real time in the ship's recording equipment, reducing the need for actual on-board investigations.

3. Future disruptive technologies

Hydrogen fuel power technology is a representative of disruptive technology in the world's ocean transport equipment frontier technology. With true zero emissions, the International Energy Agency (IEA) sees hydrogen as a fuel option for meeting the IMO's 2050 carbon reduction targets for the shipping sector. If the hydrogen fuel power technology can be mature and widely used, it is expected to reshape the form of the Marine transport equipment industry, and have a profound impact on the design, final assembly, supporting and service of Marine transport equipment. In recent years, more and more shipyards, energy companies, and power system suppliers have begun to accelerate the research and development of hydrogen fuel-powered ships, and substantial progress has been made. There are already several ship models powered by hydrogen fuel cells, and many more large-scale projects are under development.

Third, the status quo and problems of China's Marine carrying equipment scientific and technological capabilities and industrial structure

After years of development, the scale of China's Marine carrying equipment industry continues to grow. From January to November 2019, China has 1,052 shipbuilding industry enterprises above designated size, and the main business income is about 394.77 billion yuan. China's Marine transport equipment industry chain is relatively complete, covering the whole chain of research and development design, final assembly and construction, power and supporting, and service, which has strongly supported the development of Marine industry.
