After continuous
operation to the right
of the best efficiency
point, the operator
injected a drag reducing
additive (DRA) to
increase the throughput
of the 3 x 50 % units.
The DRA lowers the
system resistance
allowing additional flow
to be pumped to shore.
The cost of injecting
DRA was in excess of
500,000 USD per calendar
month. Sulzer Pumps were
able to retrofit the
existing pumps with
high-flow,
high-efficiency
cartridges, reclassify
the drive motors and
provide service
personnel to manage the
change out. The exchange
took less than four days
thus minimizing the
scheduled loss of
production. Thanks to
the retrofit, an
additional total flow of
20,000 barrels per day
was achieved.
