Daewoo puts 7MW turbine on hold to build foundations

SOUTH KOREA: Daewoo Shipbuilding and Marine Engineering (DSME) has put on hold plans to design and build a 7MW turbine due to "unfavourable market conditions", moving instead into jacket manufacturing.

The Daewoo 7MW turbine is unlikely to become reality

A source from within Daewoo said that the South Korean firm has no plans to develop the turbine in the near term. The prototype of the Daewoo turbine had been due to be installed in 2013.

The source said that market conditions in Europe, where the company had intended to sell the machine, have put development on hold, adding that DSME may return to the project if the situation changes favourably.

The manufacturer announced at the EWEA 2011 Offshore conference that it would develop a 7MW three-bladed medium-speed offshore turbine. The IEC Wind Class IA turbine was to be fitted with a 160-metre rotor.

The source went on to say that the company is now investigating the possibility of making jacket foundations for wind turbines in European waters.

DSME would fabricate the steel tubing in South Korea, where labour is cheaper, and would then ship them to Europe, where the jackets would be assembled for installation on North Sea projects.

He anticipated that despite higher transport costs, the company would be able to deliver jackets at a lower price than European manufacturers.

However, DSME will only begin manufacturing once it is sure that it has a significant enough pipeline to make it financially viable. Heo anticipated that around 100 orders a year would be necessary to cross this threshold.
