Critical utility systems such as nitrogen gas, plant air and instrument air are required in any new extensions of oil and gas facilities. Changes or additions to these systems often involve shutting down large parts of the main process systems. When reviewing Izomax proposals and comparing to alternative solutions, the client saw the possibility of reducing the planned shutdown if the tie-ins could be performed while the utility systems were kept operational. A total of 9 tie-ins were required to enable the required extension of the 3 systems.
- Extended production shutdown required for alternative solutions
- Tie-in with no hot work
- Few, if any, alternative solutions available without extending planned shutdown
- First Izomax project for client
