Learning Objectives

Upon successful completion of this course, participants will be able to:

1. Fundamentals of Shutdown Valves (SDVs) in Oil & Gas

• Understand the role of shutdown valves in emergency shutdown (ESD) systems.
• Identify types of shutdown valves:
• Ball valves.
• Gate valves.
• Butterfly valves.
• Globe valves.
• Learn about actuation mechanisms:
• Pneumatic actuators.
• Hydraulic actuators.
• Electric actuators.
• Solenoid-operated valves.

2. Selection and Specification of Shutdown Valves

• Choose valve types based on pressure, temperature, and flow conditions.
• Ensure material compatibility with hydrocarbons, corrosive fluids, and extreme environments.
• Understand valve sizing and pressure class ratings (ANSI, API, ASME).

3. Shutdown Valve Operation and Control Systems

• Learn about fail-safe mechanisms (fail-open vs. fail-close systems).
• Understand ESD logic and integration with Safety Instrumented Systems (SIS).
• Implement testing and function verification of SDVs in process automation.

4. Maintenance and Inspection of Shutdown Valves

• Develop preventive and predictive maintenance schedules for SDVs.
• Apply non-destructive testing (NDT) methods for valve integrity assessment.
• Conduct leak detection and calibration for optimal performance.

5. Common Failures and Troubleshooting Shutdown Valves

• Identify common shutdown valve failures:
• Seat leakage.
• Stuck actuators.
• Solenoid coil failure.
• Pressure fluctuations.
• Implement corrective actions to restore valve functionality.

6. Regulatory Compliance and Industry Standards

• Ensure compliance with API 6D, API 598, ANSI/ISA 61511, OSHA, IEC 61508 (SIL certification).
• Follow best practices for shutdown valve testing and certification.
• Maintain documentation and audit readiness for regulatory inspections.

7. Emergency Response and Risk Management

• Develop contingency plans for shutdown valve failure scenarios.
• Implement real-time monitoring and remote shutdown capabilities.
• Integrate shutdown valves with fire & gas detection and process safety systems.

8. Case Studies and Practical Applications

• Analyze real-world case studies of shutdown valve failures and safety incidents.
• Participate in hands-on valve inspection, maintenance, and function testing exercises.
• Develop a shutdown valve maintenance and reliability improvement plan.
