Pipeline design – density wave amplification and slurry dynamics
The effect of density waves and slurry dynamics on slurry pipeline flow assurance cannot be predicted with current slurry pipeline design methods. Current methods are based on steady-state assumptions, assuming that the mixture velocity and density are constant in time and in the pipeline. Therefore, using current design methods a dynamically stable pipeline cannot be guaranteed. Furthermore, new experiments in vertical pipelines show that density wave amplification is possible at mixture velocities far above the critical velocity. This article presents a new temporal design method based on 1D Driftflux CFD, which is able to model growing density waves.

Which slurry transport regime should be used and why?
With five possible flow regimes to choose from for slurry transport, selecting just one can require consideration. Fortunately, one of these regimes has a simple criterion: a ratio of the particle diameter to the pipe diameter.
Transport of Pipeline Optimisation
Formulated by employees of Jan De Nul Group, the solution which won the Safety Award 2017 upgraded each facet of the pipeline transportation process, including from the activities performed in storage facilities as well as while travelling to faraway project locations.
