A focused inspection process designed to turn
technical requirements into reliable,
actionable information.
01
UNDERSTAND
Understand the Requirement
The project-specific
requirement that targets the imaging NDT technique capable to perform the
on-stream inspection for assessment of corrosion, and cracking damage in the
tank annular plate of the above ground storage tank.
02
INSPECT
Inspect with Purpose
Any of imaging UT techniques
such as multi-skip bulk wave or laminar guided wave or HOMC guided wave is
selected to propagate the ultrasonic beam from accessible annular outer ring of
the storage tank
03
ANALYSE
Analyse the Findings
Data is analysed for metal
loss, and cracking in the examination region of the annular plate around the
circumference of the storage tank.
04
REPORT
Report for Action
An annular plate condition
report with annotated images and defect details evaluated against the
project-specific criteria or API 653 in-service criteria that enables RLA
decision-making is issued.
