A processing unit converting an existing refinery site to renewable diesel, with new pipe racks, tanks and tie-ins made during a planned turnaround that could not run long.
The owner was converting part of an operating refinery to renewable diesel. New reactors, tanks and more than a mile of pipe rack had to be built beside live units, with hot work permits, gas monitoring and strict safety rules every day. Final tie-ins could only happen during a planned turnaround, and every day of overrun meant lost production across the site.
The approach.

- 01
Modules built off site
Pipe rack and equipment modules were fabricated off site and set in planned lifts, reducing work beside live units.
- 02
Turnaround scope frozen early
Tie-in scope was frozen months ahead, with every weld, valve and test package ready before the units came down.
- 03
Hour-by-hour turnaround schedule
The turnaround ran on an hourly schedule with shift reports, so the owner saw progress and pressure points every twelve hours.
- 04
Systems turned over for startup
Each system was tested, documented and handed to operations in startup order.
The outcome.
“In a turnaround every hour has a cost on the other side of the fence. We planned the work to the hour and reported it every shift.”
Turnaround manager, Jacob Wiseman
