Siemens to supply offshore wind turbines to world´s largest floating wind farm

• 30 MW “Hywind Scotland” project with five Siemens turbines of Six-Megawatt-class • Collaboration on floating wind turbines started in 2009

Siemens is strengthening its collaboration with Norwegian company Statoil on floating offshore wind turbines. For the 30 megawatt (MW) Hywind Scotland Project, Siemens will supply five of its SWT-6.0-154 direct drive offshore wind turbines. The turbines will be installed on floating foundations operating in water depths between 90 and 120 meters. The world's largest floating wind project is located in Scottish waters 25 kilometers off the coast of Peterhead in Aberdeenshire. For the new Hywind Scotland Project, assembly in West Coast Norway is scheduled for first half 2017. In 2009 Statoil and Siemens successfully installed a 2.3 MW Siemens turbine at the first floating full-scale wind project worldwide, Hywind Demo.


This Scottish pilot project demonstrates how future floating concepts for commercial and large scale offshore wind parks can be both cost efficient and low risk. The floating foundations are ballast-stabilized and fastened to the seabed with mooring lines. With their lightweight nacelles, Siemens large direct drive wind turbines are particularly suited for the floating foundations designed as slender cylinder structures. This concept has already proven its effectiveness in the 2009 project. At the same time Siemens gathered a lot of experience on the specific requirements regarding the control parameters on a moving wind turbine under offshore conditions. For the floating installation Siemens' technicians developed new controller settings for rotor pitch and yaw drive regulation.

"We are proud to once again be on board the floating wind project with Statoil, and to apply the experience we gained with the first full scale floater," said Morten Rasmussen, Head of Technology at Siemens Wind Power and Renewables Division. "Hywind Scotland is another pioneering project and has the potential to become a trailblazer for future floating wind projects."

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
