Replace large high alloy piping in existing

fiberglass vessel

Minimize shutdown time

• 6-day shutdown duration

• Shutdown cost >$500K per day in lost production

Process area constructed in

the 1990s

Existing drawings

outdated and inaccurate

CONFIDENTIAL

Project 2 Execution

13

Remove and reinstall fiberglass vessel within three

24-hour days
