The Dutch Minister of Economic Affairs, Henk Kemp, opened Sif’s new assembly and coating site at Maasvlakte 2 in Rotterdam on Friday 29 September 2017. The minister was joined by Allard Castelein, CEO of the Port of Rotterdam, and Jan Bruggenthijs, CEO of Sif.

Now that the second production line is operational, Sif has increased its production capacity to 300 kilotonnes per year. Steel cylinders and cones are rolled and welded in Roermond, which are then assembled into complete monopiles in Rotterdam. With a diameter of up to 11 metres, a length of up to 120 metres, and weight of around 2000 tonnes, the monopiles are subsequently coated in one of four coating halls, before being stored at our 42 ha site. The site now has two production lines in operations, capable of producing 4 complete monopiles every week.

Moreover, the site features a unique wharf, with a load capacity of 10 tonnes/m2 and a depth of 16.5 metres, specially constructed by the Port of Rotterdam. This allows to two installation vessels to load monopiles and transition pieces at the same time.

Sif has thereby demonstrated that we are constantly striving to improve efficiency along the chain, with the aim of reducing the total overall cost of wind farms.
