What about piping burried under the sea bed (actually burried in sea bed
with minm depth),Does 31.4 giving the calculation for Virtual anchor
length calculation,Caeser calculates it automatically & the calculations
are given in 31.1( restrained piping).
Can any body through some light on it.

Riser & sub-sea pipelines fall under B31.4 & offshore platform piping will be B31.3. Transition will be at last isolation valve on the line.
Both Samuel & Steve are right.
Best regards,
