The Siemens G4 Platform The Siemens 3.6-MW and 4.0-MW wind turbines of the G4 platform represent the culmination of an evolutionary process of geared innovation and refinement to our wind turbines that dates back to 1980. With the release of a 4.0-MW wind turbine – featuring a 130-meter rotor and a more powerful generator – Siemens has produced a machine that can generate even more power without any compromise to investment robustness. Combined with advanced control features, it allows for further improvements in higher asset utilization. SWT-3.6-120 With a swept area 26% larger than its predecessor, this wind turbine makes a giant leap forward in respect to energy yield in modern offshore wind power. The design of this wind turbine is based on its long-term experience in offshore wind power. With a swept area 26% larger than its predecessor, it makes a giant leap forward in respect to energy yield. In comparison to the SWT-4.0-120, the slightly lower capacity makes the SWT-3.6-120 a competitive choice for sites with capacity constraints. SWT-4.0-120 The well-proven 120-meter rotor, upgraded to 4 MW. This makes this wind turbine suitable for offshore environments with maximum tip height restrictions. Based on the millions of operating hours and experience accumulated from the 3.6-MW class, the capacity upgrade to 4.0-MW is founded on confidence. The SWT-4.0-120 features the well-proven 120-meter rotor, which has obtained offshore experience since 2009. This makes the installation of a 4.0-MW turbine suitable for environments where maximum tip height restrictions apply. SWT-4.0-130 The most advanced rotor in its class utilizes aeroelastic blade technology for a significant increase in swept area and energy production. By using advanced blade technologies, Siemens increased the 4.0-MW rotor diameter by another 10 meters – and the swept area by an astounding 18%. This allows for a significant increase in energy production, and due to the aero elastically tailored blade technology, this is possible without compromising structural loading.
