Clyde Bergemann Australia (VME Process – Alaska, USA)
Clyde Bergemann Australia required thermal-structural assessment of a waste heat recovery unit (WHRU) for VME Process Asia Pacific (Pikka Development Project) to verify design compliance with the intent of standard AISC 360-10 and ASME STS-1 applying project specific dead, thermal, internal pressure, wind, motion, seismic, blast and lifting loads.
What we did:
- Performed thermal-structural FEA of WHRU ducting/casing and main support beams (including tube bundle/silencer mass distribution, headers, actuator bracket, damper and inlet duct support) applying dead, thermal, internal pressure, wind, motion, lifting, seismic and blast loads to confirm design compliance with standard AISC 360-10.
- Performed structural FEA of WHRU tube bundle heat exchanger (including support beam, beam sleeve and tube sheet guides), temporary braces and lifting lugs (with lifting frame) applying dead, lifting and operational loads to confirm design compliance with standard AISC 360-10.
- Performed natural frequency FEA of WHRU ducting/casing to determine vibrational modes, compared cylindrical stack first order vibrational frequencies with vortex shedding frequency range and confirmed requirements as per standard ASME STS-1.
Outcome:
Avesta Consulting verified compliance of the WHRU ducting/casing and exhaust stack designs with the requirements of standards AISC 360-10 and ASME STS-1 considering dead, thermal, internal pressure, wind, motion, seismic blast and lifting loads.
