Subsea TOFD
Time of Flight Diffraction - weld inspection
Defects in welds compromise the integrity and stability of offshore assets.
TOFD is an advanced non-destructive ultrasonic inspection method, which provides accurate sizing of defects quickly and reliably.
It was originally developed as a method to provide accurate monitoring and sizing of through-wall height of in-service discontinuities in the nuclear industry. TOFD allows for a incredible accurate data collection and measuring the critical through-wall size of weld defects.
TOFD normally goes hand in hand with the usage of other non-destructive testing solutions such as Phased Array.

Ultrasonic waves
|
Utilizes ultrasonic waves to detect faults.
|
Exact measurement of time
|
Relies on the exact measurement of time taken for ultrasonic waves to travel from the emiting probe to the diffracted waves received by probe.
|
Time of flight
|
Measuring this 'time of flight' gives and accurate size and location of the flaw.
