The Chinese cable manufacturer ZTT has won a contract to supply the export cable system for the China Energy Conservation and Environmental Protection group’s (CECEP) 300MW Yangjiang Nanpeng Island offshore wind farm, located 30km off China’s mainland. ZTT will manufacture and deliver a 45km, 220kV export cable system to connect the wind farm’s offshore booster station to an onshore centralized control center in Yangjiang City, Guangdong province. The wind farm covers an area of around 58km 2 in the South China Sea and will comprise 55 wind turbines installed in water depths of between 23m and 32m.

Huadong Engineering Corporation is planning a 1.1GW offshore wind farm, 90km off the coast of Jiangsu Province in eastern China, using a submarine high-voltage direct current transmission system. This is expected tobeChina’s first offshorevoltage source converter HVDC system. Huadong has employed experts from the certification body DNV GL to supply technical training, advice and support for a feasibility study on aspects of the conceptual design and risk assessment. “[The] offshore HVDC transmission system is a new business for DNV GL China and the Asia Pacific region,” said Haifeng Qi of Huadong Engineering. China is committed to developing its offshore wind power capacity and plans to have 5GW installed by 2020. With all potential wind sites within 10km offshore already fully exploited, sites further afield will be essential to meet the 2020 target.
