For the Gemini project Siemens will deliver 150 wind turbines with a capacity of 4 megawatts (MW) and a rotor diameter of 130 meters each.
The wind power plant is to be located in the North Sea, 85 km above the coast of Groningen. With an installed capacity of 600 MW in total Gemini will yield 2.6 terawatt hours (TWh) of electricity per year. The wind power plant will supply clean energy for one and a half million people after being fully commissioned. The amount of energy is equivalent to a reduction in the emission of CO2 by 1,25 million tons per year.
For Siemens this is the first order for an offshore wind power plant in Dutch waters. The innovative service concept banks on the ongoing presence of a service vessel and the steady ground readiness of a helicopter.
Siemens’ 15-year service and maintenance agreement for the Gemini project is the largest service order ever for Siemens Energy Service. It will introduce a highly advanced logistics concept for offshore sites.
For the first time, a helicopter will be available for a project at all times and a specially designed, purpose-built service operation vessel (SOV) will be based at the wind farm. To ensure increased turbine availability, maintenance work can be carried out at almost all times irrespective of the weather conditions or wave height.
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.
