  1. What is the primary purpose of a fitness-for-service (FFS) assessment in the context of API 510 repair decisions?

    Answer: To evaluate whether a vessel with a flaw can continue operating safely without immediate repair

    FFS assessments per API 579 evaluate whether a vessel with identified flaws can continue safe operation, potentially avoiding costly immediate repairs.

  2. Under API 510, a rerating that decreases the MAWP of a pressure vessel:

    Answer: Always requires an authorized pressure vessel inspector and engineering approval

    All reratings, whether increasing or decreasing MAWP, require authorized inspector review and appropriate engineering documentation per API 510.

  3. A weld repair procedure must be qualified per which standard before being used on a pressure vessel?

    Answer: ASME Section IX

    Weld procedure qualifications for pressure vessel repairs must be performed and documented in accordance with ASME Section IX.

  4. When planning a repair on a vessel with stress corrosion cracking (SCC), the most important first step is to:

    Answer: Identify and eliminate the cause of the SCC before repairing

    Repairing SCC without addressing the root cause will result in recurrence; the causative agent or condition must be identified and eliminated first.

  5. According to API 510, non-pressure-bearing attachments welded to a pressure vessel are:

    Answer: Subject to the same inspection requirements as pressure welds

    Non-pressure-bearing attachments welded to pressure vessels are subject to inspection requirements because improper welding can introduce flaws into the pressure boundary.

  6. A vessel that has undergone a significant repair must have an updated inspection record that includes which of the following?

    Answer: Details of repair procedures, materials, NDE results, and inspector certification

    API 510 requires comprehensive documentation of all repair details including procedures, materials, NDE results, and inspector certification to maintain traceability.

  7. When a corroded area of a vessel shell is repaired using a weld buildup, the deposited weld metal must have mechanical properties:

    Answer: Equal to or greater than the minimum specified for the base metal

    Weld filler metals must provide mechanical properties equal to or exceeding the minimum specified for the base metal being repaired.
