Inspection Period
13 - 02– 2022
Equipment used
The inspection was carried out using:
Silverwing Floormap-3Di-M Scanner
UT Machine USM/DMS GO
Scope
MFL Inspection was conducted with a view to find out corrosion,
metal loss, pitting etc. on the bottom plates and to determine the
current condition of tank.
Reference
API 653
ASME Section V
Procedure ISS/ANDT/TMFL/GP/001, Issue-1, Rev-4
Floor map 3Di-MR Operation Manual
Calibration
Calibration of the MFL unit was obtained by utilizing a plate of
similar material and thickness with artificial defects to facilitate in
establishing operating sensitivity and system linearity.
Limitations
Floormap-3Di-MR signals do discriminate between top and
bottom surface originating defects separately.
Welds & areas under pipe inlet/outlet have not covered by this
inspection (MFL).
Floor Cleanliness
The floor had been cleaned to a sufficient standard to allow a
meaningful inspection to take place.
Plate Numbering
System
Scanning was begun from south east side.
MFL Results
65 bottom plates were scanned by Floor Map 3DI-MR equipment
and metal loss of 40% and above location are cross verified by
manual UT and locations are clearly marked at site.
Row’s identification was marked from south to north direction
and plate’s identification was marked from east to west
direction, respectively.
Bottom Plate Results:
- Total No. of locations identified by MFL & UT 137 on Bottom
plates.
(MFL & UT Reports Attached)
The X / Y co-ordinates and the corrosion severity was confirmed
by ultrasonic inspection and found the same.
UT Corrosion
Results
Since the critical zone is not covered using MFL Technique,
manual UT was done throughout the critical zone and SUMP
(Shell-Bottom).
UT report is attached along with the report as well as with UT
reading for Bottom plates. (See the attached)
Max Defect per
Plate
Individual Plate
Drawings:
An image of the tank floor surveyed is shown with each plate
color coded to the maximum material loss detected by the Floor
map 3DiM-R inspection. This drawing is used to quickly identify
areas of concern in the tank floor.
Drawings of plates that have defect indications in excess of 40%
loss of the nominal plate thickness have been printed out. The
location and severity of any corrosion indication in excess of 40%
loss is shown on the attached plate drawings.
Non-Relevant
Indication
During the scanning, non-relevant indications may have appeared
because of surface dirt, plate overlap, electronic noise, weld
scars, grinding marks, spatter etc. These shall be neglected.
