Vortex Induced Vibrations (VIV) may cause significant fatigue damage in Steel Lazy Wave Risers. The severity of the VIV fatigue damage is dependent on the natural frequency of the riser and the vortex shedding frequency which varies according to long

Use of steel lazy wave risers has increased as oil and gas developments are happening in deeper waters or in parts of the world with no pipeline infrastructure. These developments utilize FPSO’s with offloading capabilities necessary for these deve

Over the past few years, a number of deepwater projects that use steel lazy wave risers have been commissioned or are under development. Steel lazy wave risers have an advantage over steel catenary risers as they offer flexibility of use with a float
