Siemens Energy has launched its
new 6-mw direct drive wind
turbine that will be available with
rotor diameters of 120m and 154m. It is
designed for the most challenging
offshore sites. It features the Siemens
direct drive design with 50 per cent
fewer parts than comparable geared
wind turbines. With a tower head mass
of roughly 350 tons, the SWT-6.0 is the
lightest machine in its class. This
unique combination of robustness and
low weight significantly reduces
infrastructure, installation and service
costs, and boosts lifetime energy
output and profitability.
Siemens is the most experienced
player in the offshore wind power
sector. The company pioneered the
industry when it installed the world's
first offshore wind power plant in1991.
Since then, Siemens has successfully
installed more than 700 offshore wind
turbines with a combined capacity of
more than 2,000 mw in European
waters. In offshore wind power alone,
Siemens has an order backlog of more
than 1,100 offshore wind turbines
with a total capacity of more than
4,000 mw.
The new Siemens 6-mw wind
turbine is purpose-built to endure
the harshest conditions offshore.
This direct drive wind turbine is
offered with two different rotor
blades. The SWT-6.0-154 features
the largest rotor blade in the 6-mw
class, using the new B75 Quantum
Blade. This 75-mlong blade delivers
enormous strength at low weight,
and thanks to its unique airfoils the
B75 Quantum Blade offers superior
performance at a wide range of wind
speeds. The SWT-6.0-120 is
equipped with the proven B58 rotor
blade. This 58 meter long blade is
known from the world's bestselling
offshore wind turbine, SWT-3.6-120.
The SWT-6.0-120 will bring direct
drive technology to customers
offshore, even in areas where air
traffic and height restrictions
ordinarily preclude wind turbine
installations of the 6-mw class.
