Featured Project

Natural Gas System Retrofit

A client required the retrofit of the existing natural gas system to allow for the installation of new gas conversion equipment. ONEC provided project management, detailed engineering, procurement support, construction, and commissioning support for this project.

The scope of this project included:

  • The demo of the existing natural gas system, the placement of a new gas header, and the 8” tie-in.
  • The placement of the local burner skids and local ignitor skids.
    The design, supply, and install of fuel gas interconnect piping and pipe supports.
  • The design and install of vent piping from the skids to an outdoor location.
    The de-termination of cables from the existing gas header, gas burner, ignitor junction boxes, and re-termination to new equipment.
  • The installation of new RVI Gas burners.
  • The installation of new FPS gas ignitor internals.

ONEC employed their “one-stop-shop” integrated approach to this project. Engineers and constructors worked as one entity to integrate constructability into the design from the onset of the project in order to mitigate risks.

ONEC successfully executed the retrofit of the existing natural gas system, the install, and the commissioning of the new natural gas system on time and on budget.
