Vertical hydraulic transport for deep sea mining Royal IHC

2016/02/24· One of the technological challenges in deep sea mining is the vertical hydraulic transport of the material from the seafloor to the sea surface. Flow assurance is vital to the entire mining operation, since termination of the transport process by for instance blockage of the riser would be a showstopper for the entire operation.

Stability of vertical hydraulic transport processes for deep

2016/10/01· Vertical hydraulic transport systems for deep ocean mining have lengths up to a few kilometers from seafloor to sea surface. Typical ratios of particle diameter d over riser diameter D are d / D = O (10 − 1), and the feeding of the riser is irregular., and the feeding of the riser is irregular.
