Describe the steps involved in conducting an emergency inspection of a pressure vessel following an operational incident, according to API-510.
Correct Answer:
Conducting an emergency inspection of a pressure vessel following an operational incident according to API-510 involves several critical steps. First, the vessel must be safely depressurized and secured to prevent further damage. The inspection team should then perform a thorough visual assessment to identify obvious signs of damage or failure. This is followed by more detailed non- destructive testing, such as ultrasonic testing or radiography, to assess the integrity of the vessel walls and welds. Any findings must be documented in an emergency inspection report that includes recommendations for necessary repairs or adjustments to prevent future incidents. The vessel can only be returned to service after it has been repaired, re-tested, and certified according to API-510 standards.
