Spanish contractor Navantia will build a quartet of next-generation jackets for the DKr300m ($44.5m) Nissum Bredning offshore wind demonstration project in the Danish North Sea, following a contract award from Siemens.

The steel three-legged design foundations will serve as the base for a concept that knits together the German engineering giant’s ultra-large 7MW SWT-7.0-154 turbine with an innovative concrete transition piece, and has built-in high-voltage cabling, transformers and switch-gear.
