API 510 Documentation 5 — Questions and Answers
Question 1: Under API 510, what is the documentation requirement when the inspection interval for a vessel is set using a risk-based approach instead of the traditional formula?
- No special documentation is required if RBI software is used
- The RBI study must be documented, reviewed by an engineer, and retained as part of the inspection record (Correct answer)
- Only the final interval in months needs to be recorded
- Jurisdictional approval alone constitutes sufficient documentation
Correct answer: The RBI study must be documented, reviewed by an engineer, and retained as part of the inspection record
API 510 requires that the full RBI study supporting an alternative interval be documented, reviewed by a qualified engineer, and kept in the vessel's inspection file.
Question 2: Which of the following scenarios requires the inspector to revise and re-issue the inspection plan under API 510?
- A routine inspection finds no defects
- A change in process fluid introduces a new damage mechanism not previously considered (Correct answer)
- The vessel passes a pressure test with no issues
- The plant conducts a fire drill during the inspection
Correct answer: A change in process fluid introduces a new damage mechanism not previously considered
When a new damage mechanism is identified, API 510 requires the inspection plan to be revised to address it, ensuring future inspections are appropriately targeted.
Question 3: What does API 510 require be documented about nondestructive examination (NDE) techniques used during an inspection?
- Only the final pass/fail result
- The NDE method, procedure, equipment calibration records, and personnel qualifications (Correct answer)
- The cost of the NDE service
- Only the name of the NDE contractor
Correct answer: The NDE method, procedure, equipment calibration records, and personnel qualifications
API 510 requires documenting the NDE method, the written procedure used, equipment calibration records, and the qualifications of personnel who performed the examination.
Question 4: According to API 510, what must be documented when an external visual inspection is performed and coating condition is noted?
- Only the overall coating color
- The condition of coating, any areas of coating breakdown, and corrosion found underneath (Correct answer)
- The brand and product number of the coating only
- No documentation is required for coating condition
Correct answer: The condition of coating, any areas of coating breakdown, and corrosion found underneath
External inspection records must note coating condition, areas of breakdown, and any corrosion found beneath damaged coating, as these directly affect vessel integrity assessment.
Question 5: Under API 510, when an inspection reveals cracks or crack-like indications, what must the inspection documentation include?
- Only the location of the crack
- Location, orientation, dimensions, NDE method used, root cause assessment, and disposition (Correct answer)
- A photograph labeled with the date only
- The operating pressure at the time of discovery only
Correct answer: Location, orientation, dimensions, NDE method used, root cause assessment, and disposition
Crack documentation must capture location, orientation, size, the NDE method that detected it, root cause analysis, and the disposition decision (repair, monitor, or FFS).
Question 6: In API 510, what is required when inspection records are transferred from one owner-user to another (e.g., upon sale of the facility)?
- The records may be discarded and a new baseline inspection started
- All historical inspection records must be transferred with the vessel to maintain continuity (Correct answer)
- Only the last inspection report needs to transfer
- The new owner must request records from the jurisdiction
Correct answer: All historical inspection records must be transferred with the vessel to maintain continuity
API 510 requires that the complete inspection history transfer with the vessel so the new owner-user has the data needed to establish corrosion rates and set appropriate inspection intervals.
Question 7: Which of the following best describes the purpose of documenting the 'next inspection due date' in a vessel's inspection record per API 510?
- To satisfy the insurance underwriter's scheduling needs
- To ensure the vessel is inspected before its calculated remaining life is exhausted, maintaining compliance (Correct answer)
- To inform the original equipment manufacturer of the schedule
- To plan contractor labor budgets for the next year
Correct answer: To ensure the vessel is inspected before its calculated remaining life is exhausted, maintaining compliance
Recording the next inspection due date ensures the vessel is re-examined before remaining life is consumed and maintains regulatory compliance with API 510 interval requirements.
