BOC Air Separation Unit Project

An initial contract was awarded to Civmec for civil works, followed by a contract for the supply, fabrication and installation of Structural, Mechanical and Piping (SMP) for BOC Limited.

The contracts involved the construction of a state-of-the-art air separation unit (ASU), to replace an existing ASU and nitrogen liquefaction unit at BOC’s Kwinana site.

Our civil scope included:

  • Site clearance, bulk and detailed earthworks
  • Drainage, earthworks and other groundworks
  • Fabrication, installation and testing of underground piping
  • Installation of underground site services
  • Fabrication of structural steel, construction of ASU shed, acoustic insulation

 Our SMP scope included:

  • Installation of structural steel, process plant equipment, tanks and vessels
  • Completion of heavy lift campaign
  • Fabrication and site installation of ASU cooling water, instrument air and process piping
  • Cleaning and testing of piping, on and off site
  • Cryogenic insulation and cladding of vessels and piping
  • Fabrication, painting and installation of ladders and platforms

We were proud to achieve our key safety objectives on this project, with zero LTIs (Lost Time Incidents) to report.
