On April 19th, Shanghai Electric received a good news from the offshore wind farm of Leting Bodhi Island in Hebei: 4MW domestic single-leaf spreader was successfully hoisted. This technology broke the monopoly of foreign suppliers on offshore single-blade spreader and filled it up. The domestic technology gap.
The single-leaf spreader supply chain at sea has been monopolized by foreign suppliers for a long period of time, and the purchase price of spreaders has remained high. In addition, the slow response of foreign technicians and the high maintenance costs of spreaders have caused Chinese owners to agonize. Shanghai Electric was established in 2016. The advanced rigging companies within the United Nations actively researched and developed to seek breakthroughs. The program was repeatedly demonstrated and the design was continuously optimized. After several rounds of tests such as field tests at Chenjiagang and factory tests, the conditions for on-site lifting were finally achieved at the end of 2017.
It is worth mentioning that this first crane was completed at night with a wind speed of 10m/s on site, and its stability and reliability have withstood the test of the site environment.
The successful development of the spreader has greatly reduced the purchase cost and improved the service efficiency. Aerial decoupling has always been a major technical difficulty in the process of wind power hoisting. Shanghai Electric 4MW single-blade spreader can complete operations at a wind speed of 12m/s, and its fully automatic Lifting, aerial demolition and other functions are at the leading level in the industry.
'Shanghai Electric is undergoing great changes and great development. Reform and innovation have become the main theme. We must make independent research and development and technology introduction form a joint force and become the internal and external power for the rapid development of the wind power group. Adhere to independent innovation, dare to take the lead, and take on China offshore wind power. The leader's role. ' President Jin Xiaolong preached at the Shanghai Electric Wind Power Group Science and Technology Conference in 2018.
The combination of technology introduction and independent research and development is a significant feature of the development of Shanghai Electric Wind Power.
As the largest offshore wind power machine manufacturer in China, Shanghai Electric has also been actively promoting the process of localization on the sea by virtue of its market advantages and positions. Based on specific projects, Shanghai Electric has set up a localization team to collect pain points from owners and feedback on industry needs. China's offshore wind power domestication.
According to relevant person in charge of Shanghai Electric, the 4MW single-blade spreader is just the beginning of Shanghai Electric's independent R&D and improvement of tooling. The follow-up will also increase R&D efforts on more megawatt leaf spreaders, cabin spreaders, etc., and continue to break through foreign monopolies. Promote the rapid development of offshore wind power in China.
