Semi-resolved CFD-DEM simulations of the rock behavior inside an inclined fall pipe

With the shift to renewable energy becoming more important than ever before and offshore wind farms being one of the sustainable energy resources available, many offshore wind farms are currently being built. <br/>One of the difficulties of these wind farms built with monopiles is that the monopiles and electricity cables must be protected from...

Rock behavior in and below an inclined fall pipe

Subsea rock installation is an offshore engineering process where rocks are placed on the seabed as protection of cables and pipelines and as scour protection. The inclined fallpipebis a new piece of equipment specifically designed to install rocks close to submerged structures. This thesis investigates the processes of the rock flow in and...

Modelling and Control of a Fall-Pipe System

A Fall-Pipe system deposits rock on the seabed for the protection of submerged objects. Due to the irregular motion of a vessel on the waves the accuracy and efficiency of the rock dumping process is limited. This thesis develops a motion compensation system for a modular Fall-Pipe system developed by Vuyk Engneering. From literature it appears...
