The decision is a response to stricter coating requirements and a change in design whereby the monopile diameters are larger and wall thicknesses smaller.
Roermond production facility
In the coming years, Sif will invest in the two facilities. Part of the halls in Roermond will be modified to facilitate the larger diameters and therefore heavier cans. At the same time, roller racks and other equipment are being modernised or adapted so that thin-walled cans can be used.
Rotterdam assembly and coating facility
In Rotterdam, Sif is currently building two extra coating halls that are due to be operational by early July. After that, the now 54 metres long hall will be extended by 106 metres. This extension needs to be ready by the end of 2019 so that we can start installing machines in the first half of 2020.
At the moment, all the cans are rolled and welded in Roermond and assembled into monopiles on the Second Maasvlakte. From 2020 onward, we’ll also start rolling and welding cans in Rotterdam. ‘We need to do this so that we can meet the future demand for larger diameters. Roermond can’t meet that demand on its own,’ says Bart Overbeek, Operational Manager Monopiles. ‘But this doesn’t mean there will be less work in Roermond. Across the entire line, we can see that the variation in requirements is growing. And the demand for smaller diameters is growing too. Internationally, the Netherlands has signed agreements to achieve specific targets in the area of sustainability. Wind energy – and therefore Sif – can make an important contribution to this.’
