The load-out of an offshore oil
facility built for the Caspian Sea
was scheduled to take place during
a period of just four days, the only
time the level and flow of the river
Volga would allow. However, the
four-day window arrived early –
before the platform was fully-built
and essential equipment was in
position. All calculations and
equipment scheduling had to be
changed at a moment’s notice.
Mammoet’s ability to act quickly,
devise a new plan and mobilize
resources without hesitation
ensured the load-out took place
on-schedule, meeting the new
deadline.
A series of four platforms linked by
bridges form the hub of the Vladimir
Filanovsky offshore oil field, in the
northern part of Russia’s Caspian Sea.
As they are constructed, the platforms
are transported by barge along the river
to their destination. The changing nature
of the Volga throughout the year means
it is crucial to perform the load-out at
precisely the right time, otherwise the
river’s flow and water levels will make
transportation impossible. The river
conditions were particularly crucial for
the Central Processing Platform (CPP),
with a weight of more than 11,000 tons.
Before construction was complete,
however, the Volga unexpectedly
reached its optimum level – which
meant the load-out had to be carried
out almost immediately, with an
incomplete platform. This created
challenges for the jack-up, skid and
load-out procedures. Principally, the
necessary equipment was not in place
and the incomplete platform was almost
20% lighter than the figure used in all
the calculations. This changed the
structure’s center of gravity and,
therefore, required a different configura-
tion of the load-out.
Mammoet’s team acted immediately to
mobilize equipment from its extensive
global pool of resources. Engineers
immediately re-calculated the load-out
and ballasting requirements based on
the new measurements. The CPP was
jacked up, weighed then mounted on a
load-out frame to provide support as it
was skidded from the quay, over a link
bridge, onto the barge. During transfer,
Mammoet’s engineers constantly
adjusted the water ballast levels to
ensure the barge remained stable.
Mammoet’s quick planning and
execution ensured the barge with its
cargo entered the Volga river within the
optimum four-day window. The CPP
was delivered to the offshore field where
it will eventually be connected by
bridges to three more platforms. The
client subsequently awarded Mammoet
the contract for the load-out of the next
platform to join the Vladimir Filanovsky
oil field.
