Siemens Power Generation (PG) has successfully
completed installation of 25 wind turbines for the
Burbo Offshore Wind Farm in Liverpool Bay. The turbines
with a capacity of 3.6 megawatts (MW) each were
erected in less than 1.5 months, well ahead of schedule.
Following commissioning and connection of the offshore
wind farm to the power grid the wind turbines will
start commercial operation by the end of the year,
supplying environmentally friendly power to more
than 80,000 households. The Burbo offshore wind
farm has a total capacity of 90 MW and will be operated
by SeaScape Energy Ltd., a company owned by the
Danish utility DONG Energy A/S.
For onshore operations, Siemens leased a 45,000
square-meter area in the port of Mostyn, located
in North Wales. The 65 m high steel towers were
assembled upright and all internal and electrical
systems were tested before they were loaded onto
the installation vessel. The purpose built vessel
carried towers, nacelles, hubs and blades for 3
turbines per trip to the site area, which is located
approximately twelve kilometers from shore. At the
site, each wind turbine was erected in five heavy
lifts with a maximum weight of approximately 185
tons. The average erection time per turbine weighing
almost 500 tons each was less than half a day.
The Burbo Wind Farm is the first offshore project
using the Siemens SWT-3.6-107 turbine and the first
in a series of offshore projects to be built by
Siemens. In a few weeks' time, erection of 48 turbines
of the SWT-2.3-93 type will commence offshore at
Lillgrund near the Swedish city Malmoe. With a capacity
of 110 MW, it will be the largest offshore wind
farm in Sweden. The Lillgrund project will be operated
by the utility company Vattenfall and commercial
operation is scheduled to start in the fall of 2007.
In 2008, Siemens will start erection work on the
largest offshore wind farm in the world off the
east coast of Great Britain. The Lynn and Inner
Dowsing project comprises 54 SWT-3.6-107 wind turbines.
The wind farm will have a maximum capacity of 180
MW and will be operated by the British gas provider
"Offshore wind energy is a key future market for
Siemens," said Andreas Nauen, head of the Wind Power
Division of Siemens PG. "Siemens is currently the
leading manufacturer of offshore wind turbines.
Our technology is making a significant and steadily
growing contribution towards the implementation
of an environmentally friendly, reliable power supply."
