MAIN BOOM EVER, TIGHT SITE

The largest main boom ever
The crews of Mammoet Europe, Mammoet Venezuela and Mammoet Malaysia had to
cope with a constricted site, poor weather and challenging logistics when they erected
the MSG 80 II at this refinery, in only 28 days. The crane was fitted with a 101 meter main
boom, the longest ever, to operate in a small footprint.
We removed an old reactor and a regenerator head and replaced them with new units.
The most interesting lift was that of the 450 ton reactor, 36 meters long, which we lifted
across a 45 meter high steel structure and then placed onto its foundations, while
operating at 55 meter radius.
The customer later presented us with a certificate as we were the safest contractor on
the whole project. Of course, safety always comes first at Mammoet, but it is good to
see those efforts appreciated.
Pressure vessel takes a turn
A Belgian company fabricated a large
pressure vessel in sections, which had
to be rotated for final assembly. First the
sections were moved out of the workshop
on SPMTs. We then used two
telescopic cranes to lift the sections and
two to turn them. The cranes were perfectly
synchronized, and it was amazing
to watch the operation. Once completed
the vessel (61 meters long by 16 meters
diameter, 1,230 tons) was transported to
the Port Arthur refinery in Texas, USA
where it will also be installed by
Mammoet.
