Common Challenges & Our Solutions
Challenge
Brownfield Complexity
Working within existing process units with limited access and congested piping requires detailed planning and experienced crews.
Solution
3D modeling and constructability reviews before field work
Challenge
Shutdown Windows
Critical path work during turnarounds with no flexibility on schedule. Must execute flawlessly.
Solution
Pre-turnaround planning with detailed work packages
Challenge
Hazardous Environments
Refineries present multiple hazards including hydrocarbon exposure, confined spaces, and hot work in classified areas.
Solution
Experienced turnaround supervisors and craft labor
Typical Outcomes
All critical path work completed within turnaround windows
Zero safety incidents during complex brownfield work
Field modifications executed without engineering delays
Repeat contracts for refinery maintenance and capital projects
