Siemens D6 direct-drive wind turbine obtains type certification by DNV GL
• Further step in ramping up serial production
of innovative
offshore wind turbine rated at 6 megawatts
• Tested and certified for
25 years lifetime
July 24, 2014 + + + Siemens Energy has obtained type certification
by certifying body DNV GL for the company’s innovative D6 offshore wind
turbine. The model Siemens SWT-6.0-154 is equipped with a modern direct
drive generator, rated at 6 megawatts (MW) and equipped with a 154 meter
rotor. The official certificate is a further step in ramping up the serial
production of the turbine. The certification process
included DNV GL experts being given full access to the engineering and
Siemens assembly facilities in Brande as well as testing facilities at
Oesterild, Denmark and Hunterston, UK. Evaluation included assessment on
the maturity of the turbine design, its manufacturing, installation and
commissioning processes and related documentation.
The development
of the SWT-6.0-154 marks a significant step towards reducing the cost of
energy. With a tower head mass of only 360 tons the new 6-megawatt machine
is around one third lighter than comparable systems. This weight advantage
provides improved economic viability across all project phases, from
assembly to transport, foundations and installation all the way up to
operation. One SWT-6.0-154 turbine can supply up to 6,000 European
households with clean offshore wind power. This type certification for the
SWT-6.0-154 includes a 25 year design lifetime, which is an additional 5
years compared to the previous turbine lifetime that Siemens has designed
towards.
Wind power and energy service are part of Siemens’
Environmental Portfolio. Around 43 percent of its total revenue stems from
green products and solutions. That makes Siemens one of the world’s
leading providers of eco-friendly technology.
