DBM Vircon’s Scope of Work:

DBM Vircon assisted with the engineering and design of the Nitrogen skid for the upstream portion of APLNG project. The design included the full multi-disciplined 3D modeling, piping stress analysis, structural analysis, lifting studies, and the production of design drawings, piping isometrics, and shop detail drawings.

Highlights & Challenges:

With multiple skids being fabricated offshore, DBM Vircon’s challenge was to design and detail the skids in a manner that fostered repeatability during fabrication and ease of installation. The concept of delivering the front-end engineering all the way through to fabrication deliverables was not something typically completed in 2014 and is still a rarity to this day. Utilizing a highly-skilled team in-house we were able to implement fabrication philosophy during the design phase to reduce the time spent during the design and fabrication phases.
