Thanks to the CoilBuilding system, Oostwouder is able to build tanks on location. This from-the-top-downwards method starts with the top of the tank and then attaches the underlying rings piece by piece.

The circular seam is then welded in the stationary welding booth. This process is repeated until the correct height is reached. We work with rings of 1.5 meters.
CoilBuilding has a number of significant advantages:
