Piping Engineering and Design

The Onyx piping engineering and design team has extensive experience in design and construction of mechanical systems in the process industries, including:

  • Refining
  • Petrochemical
  • Pipelines and terminals
  • Offshore topsides

Because the Onyx piping engineering team is significantly experienced in construction, we are able to design systems high in constructability and operability. Our piping design team has a rolling average of over 10 years of revamp design experience, and can analyze and design pipe support systems to utilize existing facility parameters.

The team is committed to project quality, and will not complete and deliver design until all quality verifications are confirmed. We routinely convert out-of-service piping to save clients money and time. The design is complete after field surveying, measuring and checking.

Because pipe engineering occurs prior to release of design, the final design has met stress engineering requirements. Part of our success in piping design has been working within an operating congested area, especially in the field of modular design. The Onyx piping team has engineered and designed offshore topsides and process modules for overseas deployment at a Middle East lube oil re-refining plant.

Core Capabilities:

  • Out of service piping utilization
  • Congested pipe routing
  • Modular design
  • Selective demolition and reinstallation design
  • Piping system stress analysis
