High output at low risk

To meet your offshore needs, it’s vital that together with a focus on optimal energy production and risk reduction, the cost of offshore energy is kept to a minimum. The SWT-7.0-154 features the highest energy output and profitability in the Siemens offshore wind turbine family, all alongside proven technology. It is your go-to turbine for high-wind site conditions where superior performance is key.

Confident in every part’s strength

In our ongoing effort to ensure that innovation addresses your needs, any opportunity for improvement that Siemen’s isolates is explored for its maximum benefit. The SWT-7.0-154 is one such example of this. Designed to IEC 1B standards, it can be deployed even in challenging offshore conditions. The 154 m rotor features the Siemens B75 blade, which enables a swept rotor area of 18,600 m2. Despite being one of the lightest blades in its class it still maintains the strength needed for a 25-year design lifetime.

Our offshore direct drive wind turbines feature a proven and reliable technology with a long-term track record. Over 1,300 of these gearless wind turbines have been installed since 2010, and almost 200 of them are in operation offshore. So re-using the direct drive technology and learnings from the SWT-6.0-154 reduced the lead-time for type certification of the SWT-7.0-154. The result: Through upgrades in the nacelle, this premium offshore turbine provides 10% more energy than its predecessor.


Whereas the generator's permanent magnets and segments as well as the transformer upgrades are required solely for the higher output requirement, the upgraded Siemens Integrated Control System (SICS) with enhanced power converter provides even more flexibility in the turbine response to voltage and frequency, while enabling compliance with the strictest international grid code requirements. Obtaining type certification in 2016 marked the final milestone in the development process, allowing you to make final investment decisions for offshore projects and lower the risk of this investment.


Appreciated by experts

No wonder that even the trade press is convinced. Wind Power Monthly annually reviews the wind power industry’s best new products. In 2015, the SWT-7.0-154 won gold for the best offshore wind turbine since it answers all demands regarding greater automation and modular construction to reduce costs, enhance product quality, and ease transport logistics.
