Coupled crossflow-inline-torsional vortex-induced vibration of a mining riser with piggyback-pipes

Key Points

• Mining risers experience complex vortex-induced vibrations due to crossflow interactions and coupled effects.
• Key metrics show that proper design can minimize detrimental impacts from hydrodynamic forces affecting risers.
• Assessment using dynamic simulations evaluates the interrelation between inline, crossflow, and torsional vibrations.
• Findings underline the importance of considering multiple factors in engineering designs for improving stability and safety.
