In the future, the length and the diameters of the monopiles will continue to increase because wind farms will be located further out at sea, in deeper water and with more powerful turbines.
Sif Group has anticipated this at an early stage by expanding its existing production capacity. Serial production of monopiles of up to 7.8 metres in diameter started in Roermond in April 2014.
Serial production of monopiles of up to 9 metres
In the future, even more powerful turbines (8MW) will be located in deeper waters. In anticipation of this, the Sif Group plans to further increase its production capacity. By the end of 2015, serial production capabilities at Sif will be targeted for production of monopiles with diameters of up to 9 metres.
One-offs with a diameter of 12 metres
Because it continuously enhances its production facilities, Sif can react quickly to changing market conditions for offshore foundations both now and in the future.
Even today, Sif can produce monopiles of up to 12 metres in diameter as one-offs. Such size may be of interest to designers working on next-generation wind turbines. As demand increases for such supersize monopiles, Sif will adjust its serial production capabilities to provide a cost-efficient solution to its customers.
