The first million kilowatt-class offshore wind farm in China, the Dawan Offshore Wind Power Project, has produced a total of 2 billion kWh of clean electricity this year, can replace over 600,000 tons of standard coal, and reduce carbon dioxide emissions by over 1.6 million tons. It has made important contributions to the comprehensive green transformation of economic and social development, and also provided power guarantees for energy supply.
The Dawan Offshore Wind Farm Project is located in the southern waters of my country, with a planned total installed capacity of 1.7 million kilowatts. It is the largest single-capacity farm project under construction in the world. At the same time, it has also realized the world’s first shallow-sea typhoon-resistant floating wind turbine and dynamic cable system. Application demonstration. As the general contractor of submarine cable supply and construction EPC, CNKC Electric Group laid nearly 1,000km of 220kV and 35kV submarine cables for the project, and provided relevant electrical and mechanical accessories to ensure the smooth grid connection and operation of the project.
At the beginning of the construction of the project, CNKC Electric Group faced the world-class design and manufacture of large-displacement, ultra-shallow water, and typhoon-resistant dynamic cable systems in the face of ultra-large-scale submarine cable manufacturing and quality control, the key core technology of factory soft joints being “jammed”. When faced with difficult problems, we have the courage to innovate, overcome technical difficulties, and provide reliable solutions and valuable engineering experience for the project with three innovative technologies.
01 Innovative manufacturing process for world-class large-length and large-size submarine cables
CNKC Electric Group innovated and improved the large-length manufacturing process technology, the size online precise linkage control technology, the large-size cable forming technology, and the key core technology of the factory soft joint, and constantly broke through the technical bottleneck. Offshore wind farm submarine cable supply length record.
Based on advanced manufacturing technology and equipment foundation, innovative use of digital sensing technology enables production management and quality control, and covers the entire process of production and testing. Take control of worldwide puzzles.
02 World-class factory soft joint technology innovation
CNKC Electric Group innovates to improve the process control and manufacturing level of factory soft joints, develops ultra-clean environment control technology, high-performance interface fusion technology, greatly improves production efficiency and reliability, and the technical level reaches 500kV, reaching the world’s leading technical level. The world-class factory soft joint technology has been applied on a large scale in this project, and none of the factory joints have failed.
03 Realize the innovative laying application of the world’s first typhoon-resistant floating wind turbine dynamic cable in shallow sea
Based on the dynamic cable system technology in the oil and gas field and years of engineering experience, CNKC Electric Group has innovatively developed a dual-waveform shallow-water anti-fatigue dynamic cable system for the challenges of large displacement, ultra-shallow water, and severe typhoon conditions of the Dawan floating wind power platform. The system adopts the advanced DP2 installation vessel to complete the dynamic cable installation and has been successfully put into use, which enables my country to achieve zero breakthrough in floating offshore wind power and lays a good foundation for the large-scale development of my country’s far-reaching offshore wind power.
In the future, CNKC Electric Group will continue to persist in grasping the main business and independent innovation.
CNKC Electric Group will continue to adhere to the purpose of being based on the world, devote itself to promoting the construction of an international wind power city, continue to deepen cooperation with all levels of the world, focus on high-end marine equipment, continue to increase investment in research and development, create product and service system solutions, and continue to provide customers with marine The “turnkey” integrated service provided by new energy will ultimately contribute to the promotion of the national clean energy construction to a new level and the realization of the national “3060″ carbon peak and carbon neutrality.
