A novel high cycle fatigue assessment of small-bore side branches: Tailor-made acceptable vibration levels based on the remaining life of existing structures
van Beek, P.J.G.
This paper describes a novel and advanced tailor-made fatigue assessment method whereby acceptable vibration levels are based on maximum acceptable stress ranges for individual side branches. The acceptable stress ranges for each critical welded connection are based on a fracture mechanics analysis of fatigue crack growth. This method also minimizes the cantilevered (overhung) mass of small-bore side branches, whilst remaining safe for long-term operation.
