Renewable energy Rotterdam

For many years sustainable energy company Eneco has had the desire to provide Rotterdam and its surroundings with a more sustainable heat supply. That is why Eneco and energy-from-Waste company AVR at Rozenburg closed a contract to convert industrial heat from Rotterdam port area into renewable heat and energy.

For transporting this heat Eneco is installing two pipes from Rozenburg, below the ´Nieuwe Waterweg´, via Vlaardingen and Schiedam to Rotterdam. The total length of this route will be about 17 kilometers. Wagenborg helped install the first and also longest pipe. This pipe, measuring 960 m and 90 cm in diameter, has a weight of 533 tonnes. The pipe had to be pulled underneath the ´Nieuwe Waterweg´.

At the Botlek side construction company Visser & Smit Hanab drilled a hole below the ‘Nieuwe Waterweg’ to clear a path for the pipeline. The pipe was manufactured on the other side of the water, near Vlaardingen. It was made in 18 m sections, which were welded together to give a total length of 960 m. Subsequently, the pipe was coated to ensure that it remains in good condition for many years to come. After these preparations the pipe could finally be positioned for the pulling operation.

During this operation the entire pipe was positioned on conductors while Wagenborg’s eight mobile cranes kept it at the right angle. With three 200 tonne and five 80 tonne cranes the pipe was successfully placed underground at the right angle. The drilling machine on the Botlek side was functioning as a kind of pulling machine and dragged the pipeline underneath the Nieuwe Waterweg at a speed of 100 m an hour. The lowest point reached was 38 m below sea level.


The entire operation went according to schedule and at the same time shipping traffic could pass without hindrance.
