LOCATION

ENI Refinery in Sannazzaro de' Burgondi

Heavy duty at height!

Following a fire at the Pavia refinery in Sannazzaro de' Burgondi, a 100 m high structure remains compromised and unsafe. Armofer plans the securing and subsequent total demolition with a project that is unique in Italy and perhaps in Europe: the customisation of large construction vehicles (total operating weight 49 tonnes) to raise them armed with powerful iron shears to a height of 100 metres without burdening the structure. It was possible with a special remote-controlled system, the modification of the means of work (anchoring and lifting systems, cameras and surveillance equipment, arms and tools with relevant CE conformity) and securing them to powerful cranes: three at the same time, one to lift the work vehicle, one to secure the structure to be moved (pulls up to 60 tonnes) and the third dedicated to the operating personnel in safety, so it was possible to section the structure. Operational phase 1 from + 100 m to + 50 m, phase 2 from 50 m to the ground. From the ground, UHD excavators of operating class 90-120 ton were then deployed to tackle the pile of carpentry and plant that had originally been placed at height, but had collapsed on the lower floors. Service and support mechanics always present on site to continuous operation and work completed without any breakdowns or stoppages.
