For atedionyahoo. Do you mean the standard buckle detector (like a gauge plate)? I know that for deep water application it's not a standard to use it because the risk of rupture of buckle detector itself.

Can't use a conventional buckle detector with reeled pipe - the pipe is one continuous length and so unless you want to insert ?km of cable inside the reeled pipr it won't work. Flipside is reeled pipe will have a low D/t ratio (typical rule of thumb D/t < 20) and is thus lees prone to buckling to begin with.

Conventional buckle detectors can be used in J-lay, no more of a PITA that when used with S-lay.
