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.
