Proven robustness with millions of operating hours
Keeps risk of investing in offshore wind power low
To meet your offshore energy needs, robust technology is a must. That’s why the SWT-4.0-130 and 120 feature technology that allows a significant increase in energy production without compromising structural loading. A proven layout, strong structure, and service-friendly nacelle ergonomics ensure that by choosing a 4.0 MW turbine you are choosing increased offshore wind energy benefits – alongside turbine resilience.
Improved efficiency without concessions is the name of the game for the 4.0 MW turbines. To get the most out of your offshore wind power investment, productivity has been taken to the next level: the SWT-4.0-130 features the largest rotor for geared offshore wind turbines coupled with a powerful generator that increases net annual energy production (AEP) by up to 15% at IEC I conditions compared to its retired predecessor SWT-3.6-120. Thanks to Siemens’ advanced blade technology, the weight of structural components is well balanced. The SWT-4.0-120 features the smaller 120-meter rotor. This makes the installation of a 4.0 MW turbine suitable for environments where maximum tip height restrictions apply, so even more sites become an attractive option.
Like any long-term investment, the sustainability of your offshore wind power project is essential to ensure future returns. This is why the Offshore Geared turbines are the most popular choice for low-wind sites and emerging markets where unrivaled experience is key. The first commercial wind farms with Siemens geared wind turbines were installed offshore in 2007 – making them the most installed offshore wind turbines worldwide: more than 1,600 units altogether. A fully developed supply chain for off-the-shelf components in the turbine as well as optimized foundations, custom installation, and service vessels, along with a trained workforce, keep your investment safe.
