Hull's first turbine blade from Siemens factory

The 250ft (75m) blade is the first to be produced at the factory on Alexandra Dock

A new wind turbine factory in Hull has produced its first blade for use in an offshore wind farm.

Business Secretary Greg Clark said it "marked a big milestone" in the future for Hull and manufacturing in energy.

The blade is to be supplied to DONG Energy for the Race Bank wind farm in the North Sea.

Associated British Ports and Siemens are investing about £310m on manufacturing, assembly and servicing factories for offshore wind industries.

The 10 acre (40,000 sq m) blade factory is part of a 133 acre (540,000 sq m) development.

The waterfront location in Alexandra Dock has been turned into a hub for wind power manufacturing, logistics and assembly.

The company employs about 700 workers at the site

In a to visit to see the 250ft (75m) blade at the site, Mr Clark said: "It's a huge day for Hull, for the Humber, but also for the country.

"Hull has established itself as an important manufacturing and engineering centre for this innovative and exciting new industry."

Juergen Maier, of Siemens, said: "I hope it will be a catalyst for further significant investments by our suppliers, customers and the industry at large."
