The role involves close coordination with piping design, structural, mechanical, civil, and vendor teams.

PRIMARY RESPONSIBILITIES:

• Perform pipe stress analysis using software such as CAESAR II or equivalent.

• Evaluate piping systems for:

  • Thermal expansion and contraction

  • Sustained, operating, and occasional loads

  • Wind, seismic, wave, and transportation loads

  • Pressure and weight effects

• Verify compliance with applicable codes and standards:

  • ASME B31.3, B31.1, B31.4, B31.8

  • ASCE 7 (wind & seismic)

  • Project-specific client standards

• Develop and review:

  • Stress analysis models

  • Stress isometrics

  • Load calculations
