Project Description

The Dow Lifetime extension in Plaquemine, Louisiana, was a two-and-a-half-year effort with excel involving various equipment enhancements and systems replacements to equip the facility with lhc2 upgrades. The planning, fabrication, and turnaround project was divided into work element releases 1 & 2 to navigate the covid pandemic and to minimize the impacts of facility production.
During both phases of the project, excel team worked in tightly compacted spaces. The site team developed creative ways to maneuver equipment, set up cranes, and more. The excel safety team developed training programs for bull-rigging methods to navigate these tight spaces. Excel completed both phases with zero safety incidents.

Significant quantities achieved throughout the 143,000 work hours include over 4,500 linear feet of air pipe, 3,200 linear feet of cable tray, 169,500 linear feet of cable, nearly 31,000 pieces of conduit, and 7,270 field welds.
Excel was able to surpass scheduling expectations, saving Dow nearly $1 million in production halts.
