API 653 compliant inspection and repair of aboveground storage tanks at a major oil terminal
AETERNA was contracted to perform API 653 inspections on a fleet of aboveground storage tanks at a major oil terminal. The scope included internal and external inspections, ultrasonic thickness measurements, settlement surveys, and integrity assessments to ensure continued safe operation.
18 tanks including floating roof and fixed roof designs
UT mapping, MFL scanning, vacuum box testing, settlement surveys
6 tank repairs supervised to API 653 and ASME PCC-2
Multiple tanks required internal entry and cleaning before inspection. Variable tank ages required tailored approaches. Some tanks exhibited significant bottom plate corrosion requiring detailed evaluation.
Our API 653 certified inspectors performed comprehensive inspections including UT thickness mapping of shell and bottom plates, vacuum box testing of welds, and magnetic flux leakage scanning. We developed prioritized repair recommendations and re-inspection schedules aligned with the operator's integrity management program.
Tanks cleaned and gas-freed. UT thickness mapping of bottom plates at 1ft grid intervals
API 653 evaluation of shell, bottom, roof, and structural components
Supervised bottom plate replacement and annular ring repairs with risk-based schedules
Measurable outcomes delivered through our technical expertise and commitment to quality.
