... allocation resulting in low acoustic fatigue life. Most of the AIV-related failures can be attributed to high cycle fatigue failures at the geometrical discontinuities in the pipework. Small-bore discontinuities on the main header tend to display lower acoustic fatigue resistance than large diameter...

... by different operations, such as hydraulic fracturing. The objective of this study is to diagnose the fatigue behavior that caused by cyclic changing of pressure and temperature during different well operations. The main scope of the study is based on the fatigue failure cases in previous literature laboratory...

... Abstract Casing pipe or joint fatigue failure could happen either during drilling in rough offshore operations or production due to alternating temperatures and cyclic loading of pressure or during stimulation, specifically, multistage hydraulic fracturing, due to temperature differentials...

... and commercially efficient solutions especially when high temperatures and pressures are involved. However, in terms of fatigue, SCRs are very sensitive to environmental loading. The procedure for fatigue analysis is essentially deterministic. This paper concentrates on the probability of fatigue failure...

... shedding on corrugations of the innermost layer of the flexible riser carcass. These pressure pulsations can be sufficiently extreme to cause vibration induced piping fatigue failures, for example to small-bore connections on both topside and subsea piping. The problem has been seen to occur for gas flow...

This methodology was used to test a replica of the Flow Termination Assembly currently deployed sub-sea on Schiehallion. The work showed that a fatigue failure was indeed possible, but the necessarily unfavourable condition had...

This definition embraces failures due to creep, hysteretic, structural realignment and abrasion in cycling as well as failures...
