Findings (2)
R-PV-12Internal inspection overdueRecords / traceabilityS3 × L3 = 9Moderate
No internal inspection has been recorded within the interval.
Action Book the internal inspection at the next shutdown and clean the vessel in advance so the survey is not deferred again.
Loss of design or inspection traceability · due 2025-08-27 · AS/NZS 3788 §6.4
R-PV-14Drain inoperable or condensate presentObservationS2 × L4 = 8Moderate
Condensate cannot be drained, which drives internal corrosion at the bottom of the shell.
Action Free or replace the drain and add a daily drain check to the operator round.
Structural failure under load · due 2025-07-28 · API 510 §6.4
