Two Electrostatic Precipitators in a Crystel River Florida Power Plant were in need of
replacement. Normally, the replacement of hundreds of ESP plates and other components
would require a long shutdown. However, Mammoet USA suggested replacing
each ESP as a complete unit and was commissioned to design the chamber assembly
frames, transport the chambers on site and lift them into position.
We used a PTC 35 DS with 80 meter main boom, 45 meter jib and 1,600 ton counterweight.
The ESPs (8 x 13 x 17 meters, 400 tons) were transported on site using SPMTs.
After that, it took only two hours to position the first unit, operating at a radius of 89
meters. That was quite a challenge as the ESP had only 15 millimeters clearance and the
boom only had 600 millimeters clearance.

CLEARANCE
Power station in France A new plant in Russia
The new nuclear power station at
Flamanville will have cooling water tunnels
leading to the sea. Mammoet France lowered
the components of the tunnel boring
machine down the access shaft with a CC
2400 SSL crane and assisted with the
assembly of the unit. The heaviest component
weighed 163 tons. We had to
operate on a small and crowded site,
which made the work quite difficult, but
managed to keep to the schedule. Our
new LTM 11200 and SPMTs were used to
install a gantry crane in the powerhouse.
Each of the two gantry beams weighed
180 tons and was 52 meters long.
Mammoet Seumersteel was awarded the
contract to supply a CC 2600 and two
LTM 1250s for the construction of a new
plant at one of the oldest power stations
in the Moscow region. The work was quite
different from our normal operations
in Russia. Good preparation and close
cooperation with the customer ensured
that the lifts were completed safely and
efficiently.
