Nacelle Changeout
Mammoet originally had a three year
contract with one of the largest wind energy
companies, to provide lifting service for
their wind turbines. As Mammoet has an
excellent working relationship with the client
and has expanded into the Pincher Creek
area, the contract has been extended into
the future.
LOCATION: BROWNVILLE, NEBRASKA, USA
JOB: CHANGE OUT OF TWO FEEDWATER
REHEATERS
CHALLENGE: OPERATING IN A NUCLEAR
ENVIRONMENT WITH MINIMAL CLEARANCES
Most of Mammoet’s work is replacing gear
boxes, but Mammoet recently changed
out a complete nacelle, the unit at the top
of the wind turbine which contains the
gearbox and generator.

Wolfe Island Wind Project
Mammoet Canada Eastern was contracted to receive, transport and erect 86 wind turbines
for the Wolfe Island Wind Project. As the water around the Island is relatively shallow, all parts
were first received and stored at the Port of Ogdensburg, New York. The turbines were then
transferred onto barges and subsequently delivered to Wolfe Island, a small island located in
the St. Lawrence River between Canada and the West. Due to the high volume and the limited
timeframe, a huge amount of equipment and manpower was required to deliver the turbines,
comprising over 1,000 items of oversize cargo. With the combined equipment fleet of Mammoet
Canada and Mammoet USA, a total of 27 trailer combinations, 8 trucks and 17 cranes were
used. As some of the operation was performed in two shifts, a total of 62 field staff were
brought together from various Mammoet branches.
Two Reheaters Replaced
Two feedwater reheater units at the Cooper Nuclear Station
were recently replaced. Mammoet USA Nuclear Division crews
installed a skid system to maneuver the heaters through the
room and position them under the opening in the ceiling. The
heaters were approximately one and a half times the length of
the opening in the ceiling, requiring the design and fabrication
of a special hydraulic lifting frame that would allow the crew to
lift the heater at a 45 degree angle to pass through the opening.
The units were then hoisted with the overhead crane to a staging
area where they were prepared for off-site transport.
