Описание: Offshore oil companies commonly employ Steel Catenary Risers (SCRs) as a means of connecting surface installations with subsea pipelines. Steel catenary risers are subject to harsh environmental conditions that include cyclic loading as a result of wind and wave motion, tidal flow, vortex-induced vibration (VIV), and operational changes to temperature and pressure. These conditions make welds, and other stress concentrating features, sensitive to fatigue cracking when in service. To mitigate against premature failure while in service, fabricators are often required to test the fatigue resistance of any proposed weld procedures before their use in SCR installations.
