Demolition of a tank with a diameter of 60 meters.
In the autumn of 2018, we received a call from a regular customer in Antwerp asking if we could dismantle an old naphtha tank that had been empty for years before the end of the year.
We couldn't do that, but we did have a counter-proposal: make the tank so unusable that it could be removed from the environmental permit. We would then do the dismantling itself in January 2019. The customer agreed.
In the steel tank, with a diameter of 60 meters, we first made a hole of four by four meters in the tank wall. Then, after we had cut away the floating roof, we drove in a heavy demolition excavator to demolish the tank from the inside.
The tank consisted of rings of steel that became thinner towards the top. The bottom ring had a thickness of 24 mm, the top was 9.5 mm thick. We make about 40 usable road plates with dimensions of 5 x 1.8 meters from rings 4 and 5, with a material thickness of 17 and 14 mm.
So we process them as nicely as possible. All remaining steel is removed.
