Removal of floating tank roof in Wesseling

DDM Deutschland recently removed a floating roof from a large storage tank. The floating roof weighed no less than 125 tonnes. In order to gain access to the tank roof, two existing access openings (manholes) had to be opened from above, as access to the tank roof was not possible in any other way due to a defective staircase. Not an easy job!

The dismantling specialists were transported to the top of the tank roof in a work platform. During the work on the roof, the dismantling specialists wore respiratory protection, gas detectors and rescue harnesses, as there could be a toxic, explosive or oxygen-deficient gas atmosphere. Clearance measurements were taken prior to the work to ensure safety.

To remove the roof, 26 steel trestles had to be assembled first. The trestles served to stabilise the roof. In the meantime, the necessary mobile cranes were assembled. The roof was cut loose in parts with the cutting torch so that the pieces could be lifted out of the tank with a mobile crane. Finally, the roof was scrapped at the designated scrap yard and recycled by authorised processors.

Safety was again a top priority in this project. The work was continuously supervised by at least two safety supervisors.

DDM looks back on a successful project with, once again, zero incidents. The tank was delivered to the client two weeks earlier than planned with not a single dent or scratch in the tank bottom.
