Crude Unit Vacuum Overhead Condenser Module, Furnace Replacement

Back to case studies

Ausenco completed the detailed design and associated field work for this fast-track project in three months. The project is located in Los Angeles, CA and was executed remotely in Calgary. The scope of this US $20 M project included the addition of a new crude heater and vacuum overhead condenser structure.

To aid the design team and facilitate the tie-in, a laser scan model of the facility was incorporated into the Ausenco design. This allowed new piping systems to be accurately routed within and around the existing facilities. The available window to remove the existing vacuum overhead condenser structure and install the new structure was limited and the accuracy of the design models was critical.

The structural steel fabricator provided Ausenco with their detailed X-steel model which was then referenced into the design models for the final interference check. The new vacuum overhead condenser structure, all equipment and associated piping were pre-assembled at site local to the existing structure.

In one day, the existing structure was removed and the new structure was set on the old foundations.

Project highlights:

  • remote execution using project point and laser scan data
  • minimal site visits and manual data collection
  • eliminate pipe spool trim allowance and fit-up
  • incorporate structural fabricator model for final interference check
  • maximise vacuum overhead condenser structure pre-assembly to minimise plant shutdown time
  • detailed design model review with owner operations and maintenance personnel.
