A delivery ceremony for the offshore converter station of Jiangsu Rudong offshore (H6, H8, H10) wind power flexible DC transmission project was held in Shanghai Zhenhua Heavy Industries (Nantong) Co., Ltd. on July 8. CCS, as a third party providing authentication and survey services, participated in the design, construction, transportation, installation and commissioning of the project, and escorted the project safety with professional services, which won the trust and support of all parties.
Fan Qiang, the Vice President of CCS, attended the delivery ceremony and delivered a speech. He said that CCS, as one of the leading classification societies in the field of offshore engineering business, has gained rich engineering experience and established a perfect technical standard system related to offshore wind power through a large number of project practices. CCS is willing to work hand in hand with the industry to establish a safety chain of offshore wind power and contribute to building a "quality power" and a "maritime power".
By far, CCS has completed classification surveys for more than 60 wind power installation platforms and authentication surveys for more than 40 offshore step-up substations, and has trained a professional service team with excellent skills, good services and tremendous courage to take responsibility.
Yang Qi (the General Manager of Jiangsu Branch), Li Linbin (the Deputy Director of CCS Marine Business Division), Hang Zhongjiu (the Director of Nantong Office of Jiangsu Branch) and Wang Rong (the Manager of Offshore Wind Power Project Department of Jiangsu Branch) attended the delivery ceremony.
This is the world's largest and Asia's first offshore converter station invested by China Three Gorges Corporation and jointly constructed by the Three Gorges Energy, China General Nuclear New Energy Holding Co., Ltd. and Shanghai Zhenhua Heavy Industries Co., Ltd., providing a solid equipment and technical support for China to enter the deep-water offshore wind power development field.
The Three Gorges Rudong offshore converter station is used to collect 1,100 MW of electric energy from three nearby wind farms (H6, H8 and H10), then convert it into DC with lower loss, and transmit it to the onshore (station) through submarine cables. It is the first offshore ±400 kV wind power flexible DC transmission project in China. The DC submarine cable-based transmission distance is about 100 km, and is rated as the highest voltage grade and the longest transmission distance in China. When the project is fully put into operation, it can provide about 1.36 million households with annual electricity consumption, and effectively contribute to the "3060" double carbon reduction target.
