#3 Crude Unit Revamp Jacobs engineering group
The #3 Crude Revamp Project was a unit upgrade at the Flint
hills Resources Refinery in Pine Bend, Minnesota. The project
would increase production from 100,000 to 150,000 barrels
per day at an estimated cost of $170 million. One major
element of the project was the addition of a new heater.
From a structural design perspective, the location of the
new heater presented challenges.
As with all unit upgrades, physical plot space was very
limited, but the most challenging element was what was
below ground. The most notable items were two 24-inch-
diameter cooling water lines four feet below grade, which
could not be taken out of service to be relocated. Using
Bentley’s STAAD products, the firm was able to analyze
and design the large, complex foundation with ease,
knowing that the results would be accurate.
Oil Product Pipeline (Construction Phase I) Jsc giprovostokneft
JSC Giprovostokneft’s project was to model a terminal tank
farm, part of the Kstovo-Yaroslavl-Kirishi-Primorsk trunk oil
product pipeline. The new oil pipeline will establish a new
light-oil export corridor for shipment via the Primorsk marine
terminal near Saint Petersburg in Russia. The project includes
construction of line facilities, rehabilitation of an existing head
pump station, construction of six intermediate pump stations,
and rehabilitation of a terminal tank farm.
Using AutoPIPE, the firm designed and analyzed the aboveground and underground pipelines in a complicated geologic
and climatic environment. It automated the calculation of
pipeline/soil interaction characteristics and developed a
procedure for active length calculation with the selection
of optimum soil points. AutoPIPE compliance with Russian
standards, codes, and regulations also enabled the firm to
avoid the purchase of additional certified software tools.
