Caesar Pipe Stress for Seismic

I need a qualified stress analyst to run five small-diameter petroleum piping models in Caesar II (or an equivalent program) and demonstrate that they meet ASME B31.4. The welded lines are all 150-lb carbon-steel headers that tie into an API 650 storage tank, and the key outcome is an accurate set of nozzle and shell loads so we can finalise the tank reinforcing pad. Scope of analysis • Build or refine the five provided Caesar models, confirm material and section data, and set up all design temperatures and pressures I will supply. • Apply the seismic acceleration parameters I provide and perform a Response Spectrum Analysis. • Combine those seismic results with temperature and internal pressure cases so the governing load combinations are clearly shown. What I will give you – Native Caesar files for the “simple” starting models (elbows, reducers, and support locations already sketched). – The full design basis: allowable stresses, SIFs, seismic spectra, temperature/pressure tables, and lateral spread at each tank during seismic event Deliverables 1. Editable Caesar (or compatible) model files for all five systems. 2. A concise stress report that includes: • Code compliance summaries for each load case • Table of forces/moments at the tank nozzle in global and local axes • Recommended spring or rigid support tweaks or flex hose if any limits are exceeded 3. PDF plots of deflected shapes for the controlling seismic combinations. Acceptance criteria • All stresses within B31.4 allowable limits. • Nozzle loads reported at operating, occasional, and sustained conditions. • Clear documentation of every load case and combination used. I’m ready to answer questions quickly and can turn around missing inputs within a day, so let me know what else you need before you start.
