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.
During a ceremony at the IADC Annual General Meeting in New Delhi, IADC President Frank Verhoeven announced the Safety Award 2019 winner: Boskalis with its Floating Line Connecting System.
19 August 2019 - IADC is proud to announce fourteen nominations in the running to receive the Safety Award 2019. The winner will be announced on 17 October 2019. 1st nomination Safer shock-prevention monitoring box from Bender Benelux installed on all Boskalis mobile generators
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.
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.
To encourage the awareness of safety within the dredging industry, the International Association of Dredging Companies (IADC) presents an annual award to an exemplary programme or project which advances the application of safety throughout the dredging industry’s activities.
