6.0 Conducting An FMD Test
Having completed the hardware setup (Section 4.0) and software setup (Section 5.0) the ISFMD
system is now ready for operation.
For certainty of operation, it is recommended that prior to testing members subsea, a known
flooded member/non flooded member should be checked to ensure system is setup correctly
and fully operational.
Using the seaView FMD application, conduct a FMD test as follows:
Step 1:
Input parameters of member to be tested
•
Click on
'Setup'
◦
Input member Diameter
(
Critical
)
◦
Input Transmit Power
(
Critical
)
◦
Set Length of member (if known)
◦
Set Member Angle (if known)
◦
Set Depth of lowest point (if known)
Clicking the
'Close'
button will save the settings and automatically configure the acoustic
settings of the ISA500 Probe to suit the member to be tested.
It is
critical
that a correct member diameter (in meters) is entered - the system will
restrict the test window to the range entered - ignoring any returns beyond this range.
It is also
critical
that a sufficient power level has been chosen for the member under
test.
In general the power level should be set to as high as possible without causing
spurious readings.
Step 2:
Place the ISA500 blue circular transducer in direct contact with the member to be
tested. The mating surface of the member should be clean and free from
marine growth
Step 3:
Click on
'Ping'
in the seaView FMD Application
•
If a return is detected the distance measured
will be displayed in the pipe profile. This
indicates that the member is flooded:
•
If no return is detected, no value will be
shown in the pipe profile. This indicates that
the member is not flooded:
Example: Not Flooded
Example: Flooded
