New giants at sea

Thursday, 7 February, 2013 - 15:15

DONG Energy has erected two wind turbines, each with a rated capacity of 6 MW, at the offshore wind farm Gunfleet Sands in the UK. Siemens was already testing two of these turbines onshore in Denmark but these are the first of the 6 MW turbines to be erected offshore. They should be connected to the grid sometime in the spring.

The two turbines, which have a rotor blade length of 120 m, were erected by the Sea Installer, the new construction ship from A2SEA. Once again, installing the turbines with the rotors pre-assembled proved to be a quick affair: DONG needed less than 24 hours to install the two systems. The construction of the two turbines completes the installation work at Gunfleet Sands.

"These new wind turbines will participate in reducing the cost of energy", said Morten Hultberg Buchgreitz, member of the board of DONG responsible for wind power. "Cost reduction is a primary concern in relation to the competitiveness of offshore wind energy. It is therefore of great importance that we use the latest technologies at an early stage – as at Gunfleet Sands – in order to make full use of them later."

DONG reached a general agreement with Siemens in July 2012 for the delivery of 300 of the 6 MW turbines. They are intended for the Danish company's British projects.
