Flexible execution within a critical shutdown window
Crossbridge Refinery in Fredericia carried out TA26, with Jernbro as contractor for a planned shutdown.
The scope included work on 52 heat exchangers, 27 air coolers and 52 vessels, as well as replacement of selected components in the plant, while other contractors simultaneously carried out maintenance and modernisation projects.
The shutdown lasted three weeks and was completed with 76 Jernbro personnel, divided between management and seven crews.
Challenge
During start-up, many contractors were working in a very limited area on the critical path. Among other tasks, Jernbro had to lift out several +20-ton heat exchangers, which affected the other parties.
At the same time, a number of unforeseen tasks and additional repairs arose, which had to be handled within the original shutdown window.
Solution
Thorough planning before the shutdown and ongoing coordination during execution ensured that the day’s and the next day’s work was carried out without impacting CBE or the other contractors.
The repair team handled, among other things, pipe leaks, welding and turning tasks, as well as other repairs.
The tasks were completed with a focus on quality, safety and fast response times.
Results
All known repairs and unforeseen defects were identified and rectified within the shutdown window. Hydraulic and mechanical torque tightening was performed, supplemented by bolt tensioning as an additional task.
There was close collaboration across contractors and with Crossbridge, with a focus on safety.
Delivery was completed without remarks, and start-up proceeded without leaks or issues that could delay daily operations.
Why choose Jernbro
- Rapid handling of unforeseen faults during the shutdown
