Pressure Vessels, Equipment Design & Engineering


Utilizing both in-house teams and our EPC partner network, we deliver turnkey and custom solutions for all your ASME pressure vessel and production equipment needs, backed by decades of experience serving upstream, midstream and downstream oil and gas markets.

Our expertise spans a broad range engineering disciplines including civil, structural, mechanical, piping and process engineering as well as electrical, instrumentation and controls.

In conjunction with our extensive service offerings, we’re able to deliver seamless project execution from conceptual design and all phases of engineering, fabrication, delivery and installation, start-up and commissioning.

In addition to pressure vessels and production equipment, we deliver an array of engineering projects to support all aspects of NGL & LPG storage and handling operations from wellhead to burner tip.

From transport loading/unloading, pumping, and metering solutions to complete NGL or LPG truck, rail or marine terminal or bulk plant installation, our experienced team of engineering specialists can offer you a broad range of options from fast-ship standard offerings to fully custom engineered and constructed projects delivered to your exact specifications.

Based on the nature of your project, engineering services may include some or all of the following:


  • Site specific conditions evaluation
  • Preliminary equipment specification
  • Conceptual process design
  • Modeling & simulation
  • Preliminary P&IDs
  • Process flow diagrams
  • Preliminary piping specification
  • Preliminary instrumentation specification including control valves, flow instruments, level instruments, pressure and temperature gauges, relief devices
  • Control & safety device definition



  • Further development of basic engineering
  • Preparation of equipment data sheets
  • Codes and regulations specifications
  • Finalized P&IDS
  • Piping, instrumentation, electrical & civil work layouts
  • Evaluation of all options to determine best ROA (return on assets)
  • Final project scope definition and preliminary cost estimates

FREE ASME Pressure Vessel Material Analysis - MAWP - Max Allowable Working Pressure Guidance

FREE Preliminary Vessel Material Analysis

Without the right data to optimize your vessel design, it's easy to miscalculate design pressure by overcompensating for MAWP.  This can lead to incorrectly sized vessels and other  issues including unnecessary costs, underperforming assets—and disappointing ROI,

Let our AMSE vessel design experts assist you with a FREE preliminary material analysis!  We'll help you determine the right material grade & thickness for your pressure rating for optimal vessel performance, often leading to:

  • Reduced overall vessel weight—and cost
  • More economical constructability
  • More!
