Power Plant Neurath
Mammoet was awarded a contract to supply
a PTC-DS for the construction of a
power station in Neurath, Germany, with
two blocks of 1,100 MW capacity each.
Because of the height of the structures,
Mammoet had to modify the PTC-DS specially
for this project and test it on site. It
was rigged with a 134.6 meter main boom
and 69.3 meter jib, for a capacity of 1,600
tons and 33,705 ton-meters. The crane
itself weighed 1,500 tons and was fitted
with 1,500 tons of counterweight. The PTC
had an overall height of 207.7 meters.
Bruce “A” Restart Project
Mammoet Canada Eastern was contracted
to provide a ring crane (PTC), smaller
cranes, site transportation and offloading
services for the replacement of sixteen
steam generators in a nuclear power
station. The scale of the project, safety
standards, numerous site contractors and
unpredictable weather conditions meant
that extensive coordination was required.
The heaviest lifts were the steam drums
located directly above the steam generators.
These drums, weighing over 400 tons each.
It took 110 shipping containers to deliver
the PTC to the site.
Mammoet had only planned to move the
PTC once between the two blocks of the
power station. However, a problem which
affected one of the blocks meant that
Mammoet actually had to move the crane
twice. It had a transport weight of 2,080
tons and was moved using 100 lines of
SPMTs.
Definitely a challenging, large-scale
Mammoet job!
The tight clearances within the facility
made it quite exciting to bystanders. The
plant, which is subject to snowstorms and
high winds, required a modified load chart
for the PTC.
