Transporting and Lifting Eleven Columns
First Expansion Albian Sands
Mammoet’s client is expanding its Albian
Sands upstream facility which processes oil
sand. The main purpose of the facility is the
processing of mined oil sand into a pipeline
transportable liquid which is then fed to the
Scotford facility near Edmonton, Alberta for
refinement. Mammoet started working on
this project in August 2007. The scope of
the work includes transporting and erecting
some 310 oversized loads ranging from
tanks and pipe modules right up to 450 ton
vessels. Mammoet has a range of cranes,
trailers and other equipment on site to
cover all the client’s needs. The highlight so
far was transporting the TSRU columns
with a diameter of eleven meters which,
with all the equipment, had a total combined
weight of 726 tons. This region of
Canada is a true cultural melting pot with
people of all nationalities and skills working
together. Working on a project which has
so many variables is a daily challenge.
Throw into the mix the impending -47˚C
Fort McMurray winter and you have a job
which is never the same two days in a row.
Over a period of 18 months, Mammoet has
been busy transporting and lifting eleven
large columns. Mammoet used a number
of cranes (PTC I, CC 4800, two units
CC 1800, CC 2400-1, LR 1350) and SPMTs.
It was also the first job in Singapore for the
1600-ton PTC ring crane which was fitted
with a 87 meter main boom and 39.4 meter
jib to erect a propylene fractionator column
which stood 106 meters tall.
After the PTC had been rigged we used 72
lines of SPMTs to move it to the first job
site. Because of heavy rain the ground on
the site was very soft. To avoid taking any
risks, Mammoet first tested the road
by driving SPMTs loaded with superlift
counterweights across it. That was
just as well, as it turned out that the
ground needed more preparation.
Mammoet discovered that the
columns were actually rather heavier
than specified. In most cases this
was not a problem as the equipment
had plenty of spare capacity.
However, the heaviest column had
to be stripped of some metalwork
before we could safely lift it.
