The Applied Technical Services Family of Companies (ATS FoC) conducts vessel overpressure assessments to identify and address risks that could cause a pressure vessel to exceed safe operating limits. Our team identifies credible overpressure scenarios, calculates pressure loads, and verifies that your protective systems can effectively mitigate these risks.
Industries like petrochemical, chemical, oil and gas, and LNG facilities rely on vessel overpressure assessments to protect their operations and personnel.
When is a Vessel Overpressure Assessment Required?
To help prevent failure, we systematically evaluate whether a pressure vessel or its components could exceed the Maximum Allowable Working Pressure (MAWP).
A vessel overpressure assessment is typically required when a credible scenario presents operational or safety risks, including when:
- Design changes, equipment modifications, or updates to relief systems that could impact pressure limits
- Incidents like loss of instrumentation, control system failures, or any event that increases pressure
- Material or process changes, especially when introducing fluids with different vapor pressures or hazard profiles
- Inspection data showing signs of corrosion or degradation, suggesting the vessel may not meet design integrity requirements
- The overpressure ratio nears or exceeds the hydrotest pressure
- Upstream pressure or energy system is imbalanced
- Liquid overfills, inflow excess occurs
Incidents like these can arise during design, after operating modifications, during safety reviews, or when equipment shows any signs of hazard.
Which Industry Standards are Applied to Vessel Overpressure Assessments?
Our licensed professional engineers follow American Petroleum Institute and American Society of Mechanical Engineers standards throughout each assessment, including but not limited to:
- API 521
- API 520
- ASME Section VIII
- API 579-1/ASME FFS-1
- API 581
