The 410m-long transport pipes are being installed for a heating network in Hengelo, which will heat houses and companies in a sustainable way. The hot water flowing through the pipes comes from a nearby AkzoNobel plant.
The project involved directional drilling. Initially a special rig was used to create the drill hole from north to south of the canal, which was then enlarged.
Two steel insulated pipes with a diameter of more than half a metre were then pulled through the borehole by the drilling rig.
The mobile cranes lifted the pipes up to a level of 5m, in order to pull the pipes through the hole underneath the canal at an exact angle. The pipes were pulled underneath the canal at a speed of 100m per hour.
