Description
This Report offers comprehensive guidance for annulus vent monitoring systems including topside piping systems. Annulus Vent Gas Monitoring (AVGM) systems have been widely deployed and can be useful for the timely identification of unbonded flexible pipe failure modes, such as outer sheath failure or leakage from the bore. This Report’s objective is to provide recommended practices to design, implement, and utilize these systems. In addition, this Report offers recommended practices for topside piping systems to be connected to the end fittings with or without AVGMs. This Report is aimed at operators of unbonded flexible pipe, flexible pipe manufacturers, engineering firms that design topside piping systems, AVGM system providers, and service companies that perform flexible pipe integrity assessments and offshore maintenance and testing.
