LPG Pipeline Process Design Support

I’m expanding an established LPG facility with two new transfer pipelines and need a seasoned process engineer to prepare the full design package. The scope covers line sizing, hydraulic and thermal calculations, safety considerations, and all supporting documents required for internal approval and regulatory submission.

Please base the work on recognized standards for liquefied-petroleum-gas service (API, ASME B31.3/B31.8, NFPA 58) and use industry tools such as Aspen HYSYS, Pipenet, or equivalent for your simulations and reports. Drafting can be in AutoCAD, Plant 3D, or any compatible format that my engineering team can review natively.

I’ll shortlist engineers who send a detailed project proposal—outline of tasks, software you’ll apply, milestone schedule, and the documents I can expect at each stage. Turnaround for the complete package is up to 16 weeks from award; please confirm your availability to meet that window.

Deliverables expected:
• Hydraulic calculations for both lines, including pressure-drop profile and surge analysis
• P&ID and line list reflecting all instrumentation, valves, and safety devices
• Material specification and class sheets for pipe, fittings, and insulation
• Control philosophy and operating manual excerpts for the new lines
• Design basis memorandum and compliance checklist against cited codes
• Process Basis of Design and legacy revalidation
• PFDs (Process Flow Diagrams), functional diagrams
• Line sizing with wall thickness and material selection input
• Pumping system design
• Tie-in list and process description report
• Input to 30/60/90% design reviews

All documents should be in editable electronic format, ready for peer review and stamping by our in-house authority. I’m happy to answer clarifying questions before you submit your proposal; accuracy now will save us both time later.
