Dynamic Operations in Offshore and Dredging

Models that predict movement behaviour are very useful for the design of vessels, systems and components. It can for instance make them more suitable to operate in extreme circumstances. A well known example is the ANySIM programme of MARIN. But the prediction of movement behaviour in combination with adjacent systems like cutter heads, spud carrier with spud poles, and suction pipes are a different story altogether. Those components influence the movement behaviour of the vessel. On top of that the seabed also influences the movement of these systems. The difficulty lies in the combination of all these different forces. The “Dynamic Operations in Dredging & Offshore” project  (DODO) studies these forces for the first time in combination with each other to be able to use them in a simulation model based on ANySIM.

In recent years, MTI Holland has invested heavily in knowledge development in that area. In experiments with location sensors, researchers track the actual behaviour of components to validate the simulated behaviour in the software. Besides IHC Merwede, MTI Holland BV and MARIN also XI Advies is involved, which provides a user-friendly interface. With the final product MTI will be able to calculate forces, reaction time, pressure, etc. on systems and components in a significantly shorter time than previously possible.
