Pipelines On bottom stability
Pipelines On bottom stability
(OP)
Hi,
I'm involved in on bottom stability study of a offshore pipeline. Due to extreme enviromental loads we are thinking about use of mattresses to ensure the stability during design life.
Since the DNV codes (RP 305 and RP F109) don't consider this situation, do you have any reference or standard practices or calculation methodology for calculation of stability of system (pipeline + mattresses)?
Thank you for your support.

The mattress must be made of components that minimize drag yet provide enough weight (weight in water) so that the mattress is too heavy to move when those drag forces from the wave and rift currents are acting on it.
