DIAB core being used in world's largest wind blade.

Core manufacturer DIAB International (Laholm, Sweden) reports that its material is being used in the fabrication of an 83.5m/274-ft wind turbine blade, said to be the world’s largest (see “Fair winds for offshore wind farms” | CT June 2013 (p. 32) | short.compositesworld.com/fEQbAlC2. As a joint project between blade manufacturer SPP Technology (Stenstrup, Denmark) and Seoul, South Korea-based Samsung Heavy Industries, the first blade prototype was designed and manufactured by SSP Technology and is now undergoing testing at the Fraunhofer Institute for Wind Energy and Energy System Technology, in Bremerhaven, Germany. The record-breaking blade was produced in support of a wind turbine development project, the goal of which is a 7-MW offshore turbine with a 171.2m/562-ft diameter rotor. Ultimately, the new design will be used in the construction of 12 units in an 84-MW offshore installation in the Korea Straits. The installation, a collaboration between Samsung and Seoul-based Korea Southern Power Corp., is targeted for startup in 2015, which will make it South Korea’s first offshore wind energy project.
