Ramboll to tackle complex Chinese seabed

CHINA: Danish engineering firm Ramboll has won the contract to design a 400MW offshore wind project in China, becoming the first non-Chinese company to do so.

The €4 million contract includes the design of 100 steel foundations, plus a substation complete with transformers, breakers and cables, the firm said.

The 400MW SPIC Binhai North Phase 2 offshore project is being developed by state-owned investment holding company State Power Investment Corporation. Ramboll is carrying out the design work on behalf of Huadong Engineering Corporation.

SPIC's project will be located 22 kilometres off the Jiangsu coast in eastern China. Ramboll said the project site is in an earthquake-prone area with soft soil.

"The seabed consists of deposits washed out by the large rivers, which poses a high risk of soil liquefaction. This puts unique demands on the design and construction of the foundations that will be placed 60-metres below the seabed, in order to support the turbines in depths of 14-18 metres," Ramboll said.

Phase 1 of the project is currently under construction, and first power is expected by the end of 2016, Ramboll said.

China is looking to install 10GW of offshore capacity by 2020, Ramboll said, despite the country having less than 1GW at the end of May 2016, according to Windpower Intelligence, the research and data division of Windpower Monthly.
