Subsea gate valve
The customer
- Size: Medium-large enterprise
- Sector: Oil and gas
- Country: United Kingdom
The project
- Size: 60-75 man-hours
- Duration: 2-3 weeks
The problem
- Structural integrity assessment required following Standards' guidelines
- ASME VIII Div 2 and API 6 methodologies followed
- Stress values during operation/test conditions unknown
Proposed solution
- Stress analysis under different scenarios of Pressure and actuator loads
- Global/local modelling strategy followed for detailed features
The simulations
- Extreme working Pressure applied (test Pressure: 1.5 x operational Pressure)
- ROV's maximum torke applied to the actuator (FEA analysis)
- Combination of the loadings according to ASME VIII Div 2 standard
Project overall results
- Valve was considered adequate for the application and the Pressure rating
- Savings over £35,000 for the customer in prototyping and testing (estimate).
- Savings of more than 12 weeks in development time (estimate).
