Pressure vessel
The customer
- Size: Medium-large enterprise
- Sector: Oil and gas
- Country: United Kingdom
The project
- Size: 45-60 man-hours
- Duration: 2-3 weeks
The problem
- Fatigue issues on some areas and weldings
- Early failure of the vessel in certain applications
- Maximum pressure capacity unknown
Proposed solution
- Stress analysis under different scenarios of pressure and loads for ASME VIII-2, BS-5500, EN-13445 and DNV-RP-C203
- Fatigue analysis simulation to estimate structure useful life (MTBF)
The simulations
- Stress analysis to find mechanical hotspots of the structure (FEA analysis)
- Fatigue simulations according to expected structure stress map (FEA analysis)
- Optimization of the design for extended product life (FEA analysis)
Project overall results
- Increase in structure useful life of 20%, maximum pressure capacity was learned from the different cases.
- Savings over £34,000 for the customer in prototyping and testing (estimate).
- Savings of more than 7 weeks in development time (estimate).
