The challenge
Risk-free conditions for lead paint removal
A major overhaul of a refinery is not an exercise to take lightly. Unexpected delays and safety hazards cost time, money and sometimes lives. Our customer was aiming for an incident-free overhaul, with zero environmental or safety reports. This meant they needed an unpleasant and potentially risky job done before they could even start. They wanted lead-based paint removed from one of their larger vessels so they could complete a welding project.
Others had tried dealing with this problem in the past but with only minimal success. The refinery asked if we could do a better job, and do it during normal operational hours.

The solution
Sealing the vessel in giant cooled tent
We worked closely with the refinery’s maintenance team to co-ordinate the project so the start date of the turnaround didn’t fall behind schedule. We rapidly sealed the vessel in a large tent and then ducted 70 tonnes of cooling with the required power. An industrial air conditioning unit supplied chilled air through ducts, which were hooked up to perforated ducting inside the tent to distribute the air efficiently. The system was balanced with air vented through high-efficiency particulate air (HEPA) filters. This allowed the tent to remain sealed but with a slight positive pressure to optimise working conditions.
