(Original title: The demand for offshore wind power is accelerated, and Longyuan Power strives to become the main force of offshore wind power)
On January 18, 2022, the Jiangsu Provincial Development and Reform Commission issued the “Notice of the Provincial Development and Reform Commission on the Competitive Configuration Results of Offshore Wind Power Projects in Jiangsu Province in 2021”, and Longyuan Power, on behalf of the National Energy Investment Group consortium, selected Jiangsu Sheyang 100 10,000-kilowatt offshore wind power project.
my country is rich in offshore wind power resources and has huge potential for development and utilization. Offshore wind power plays an increasingly important role in “carbon peaking and carbon neutrality” because of its cleanness and low carbon, close to the electricity load side in the southeast coastal areas, and convenient consumption. Offshore wind power is regarded as an important strategic support for the transformation of my country’s energy structure.
As the world‘s largest wind power operator, Longyuan Power has the courage to assume social responsibilities, and proactively entered the field of offshore wind power development. With more than ten years of riding the wind and waves, Longyuan Power has explored a road for China’s offshore wind power development that suits China’s national conditions.
Be the Pathfinder of Offshore Wind Power
Due to the poor accessibility of operation and maintenance, and considering technical requirements such as typhoon resistance and anti-corrosion, offshore wind turbines need to have high reliability, so the costs of manufacturing, transportation, installation, and operation and maintenance are all high. At the same time, affected by the complex marine environment, the foundation of wind turbines needs to deal with the long-term effects of complex geological conditions, sea ice, currents, corrosion and other factors. Unknown World“.
Longyuan Power has been a pioneer and actively entered the field of offshore wind power development with high technical difficulty and high investment risk, paving the way for the construction of offshore wind power in my country. The company selected the coastal areas of Jiangsu Province with abundant resources and good wind power capacity to set up an offshore wind power project preparatory office. , the principle of “easy first, then difficult, active and stable”, and the idea of “first experiment, then small-scale demonstration, followed by large-scale development”, in accordance with the principle of “overall planning, staged development, first easy before difficult, active and stable”, and With the idea of ”testing first, then small-scale demonstration, and subsequent large-scale development”, the world‘s first intertidal wind power project – Longyuan Jiangsu Rudong 30,000-kilowatt intertidal experimental wind power project was launched, officially opening the scale of China’s offshore wind power development layout.
Solve the problem of wind power construction in the intertidal zone and drive the high-quality development of the industrial chain
During the construction of offshore wind power projects, Longyuan Power independently innovated and solved the problems of offshore construction with a number of technologies, provided technical reserves for latecomers, and promoted the high-quality development of the upstream and downstream of the industrial chain.
In the early stage of offshore wind power construction, the company broke through the bottleneck of key construction technologies, took the lead in mastering the core construction technologies of offshore wind power such as large-diameter monopile foundations, and quickly promoted it to the entire industry, starting the process of large-scale development of offshore wind power.
It is also a major technical difficulty that heavy construction equipment can stand stably on the beach. Longyuan Power has customized the “Longyuan Zhenhua II” 800-ton jack-up full-rotation offshore wind power construction platform, which integrates the two functions of foundation construction and equipment installation. The working water depth can reach 35 meters, and it has 12 grades. The storm self-sustaining capability is suitable for the development of offshore wind power farther offshore, and in one fell swoop, my country’s offshore wind power construction has achieved a leap from the intertidal zone to the offshore.
After solving the problem of offshore wind power construction, in the power transmission link, Longyuan Power explores the offshore booster station, raises the voltage level and then sends it ashore, effectively reducing line losses. In order to solve the problem of transportation and installation of the offshore booster station, the method of “modular design and split installation” is adopted, which meets the construction requirements of the offshore booster station under complex sea area geological conditions, and reduces the load standard of the construction vessel. The modular design of other countries in the world provides new ideas for developing offshore wind power.
During the progress of the project, Longyuan Power also provided a number of domestic wind turbine manufacturers such as Goldwind and Yuanjing with a test platform for their products from “land” and “sea”, which significantly improved the performance indicators and equipment quality of domestic offshore wind turbines. promote. In recent years, Guangdong Mingyang, Shanghai Electric, Chongqing Haizhuang and other wind turbine manufacturers have settled in Jiangsu, and steel structure manufacturing enterprises such as Hengtong, Haili, Hongbo have further developed and grown, and some enterprises have also become domestic and foreign wind power developers. The main suppliers have made due contributions to consolidate the foundation for the development of the new energy industry in Jiangsu Province and promote the transformation and upgrading of the local economy.
Independent innovation to explore new paths for offshore wind power development
On December 10, 2021, the main project of Longyuan Power Jiangsu Dafeng Phase II 606,300-kilowatt offshore wind power project was completed. So far, Longyuan Power has installed 2.18 million kilowatts of offshore wind power in Suzhou. It is reported that by leveraging the long-term successful experience of offshore infrastructure work, the company completed the project construction in only 10 months, reducing the construction period by more than 6 months, creating industry records such as 22 pile sinking and 28 hoisting units in a single month, establishing offshore wind power Project construction benchmark.
According to the forecast of the International Renewable Energy Agency (IRENA), in order to control the global temperature rise within 1.5 degrees Celsius in the second half of this century, the installed capacity of offshore wind power will reach at least 2002GW, and the new installed capacity of offshore wind power in 2020 will only be less than 1.5 degrees Celsius. 7GW, which is far from this target. In the context of the global low-carbon energy transition, the compound growth rate of new overseas and domestic installed capacity will reach 35% and 44% respectively from 2022 to 2025, and the global compound growth rate will be 38%, achieving a boom in prosperity.
Superimposing the dual carbon goals, my country’s offshore wind power will usher in rapid growth during the “14th Five-Year Plan” period. However, for now, my country still lacks in the field of wind power core technology, and it is necessary for leading enterprises represented by Longyuan Power to innovate independently, to lead the industry to occupy the technical commanding heights of global wind power, and to occupy a favorable position in the new round of wind power industry reform.
Longyuan Power stated that it will continue to explore the integrated development path of “offshore wind power + offshore ranch”. At present, the company has signed the first domestic development agreement for the marine ranch demonstration project based on the commissioning of offshore wind farms in Sheyang, and began to focus on building future offshore wind power profitability. The new model explores a new path for the high-quality development of offshore wind power, vigorously develops the marine economy, and injects the power of central enterprises into accelerating the construction of a marine power.
