ZTT to Deploy Installation Fleet on Chinese Offshore Wind Super Project

ZTT will use its vessels Zhongtian 7, Zhongtian 8, Zhongtian 9, Yuanwei No. 8 and Zhongtian 5, built by Shanghai Yuanwei Construction Engineering Co., Ltd., to carry out its work.

The company is in charge of installing 100 turbines at the project site, as well as the foundations and 220kV and 35kV submarine cables.

Jiangsu Rudong (H6, H10) will be the first wind farm in China to use ±400kV flexible DC submarine cable, which ZTT developed with support from China Three Gorges (CTG).

According to ZTT, the DC submarine cable has a transmission distance of about 100km, which is currently the high voltage flexible DC submarine cable with the longest transmission distance in China.

At the end of February, CTG revealed it had started construction on the 800MW Jiangsu Rudong (H6, H10) and the 1,400MW Yangjiang Shapa offshore wind farms, described as “super projects”.

In total, the two wind farms will feature 414 turbines expected to be commissioned by the end of 2021.
