Vortex-Induced Vibration of Deep-Sea Mining Pipes: Analysis Using the Slicing Method

Applied Sciences
Deep-sea mining pipes are different from traditional ocean risers articulated at both ends: they are free-suspended, weakly constrained at the bottom, and have an intermediate silo at the end, compared to which relatively little research has been carried
