Behavior of floating solar platform - Part 2

Comportamiento plataforma solar flotante
As we promised in the previous blog, in this new publicacion on the behavior of floating platforms, we are going to show the capacity of simulacion when it comes to predicting design failures.


The first of the cases that we are going to stydy is a variation of the anchoring position of the cables, specifically, in this case, they are anchored to the bottom, as shown in the following image.

Thanks to the simulation, we can see that the behavior of the system in these wind and wave conditions, becomes more chaotic, the cables cannot hold the platform and, as shown in the following video, it ends up sinking.
Another important advantage of using CFD is the possibility to change conditions in the calculation while it is running. For example, in the following case, the breakage of one of the ropes is simulated from a certain moment of time.

The consequence is that by being left with three cables, the platform becomes unstable and drifts, until it sinks and the solution diverges.


In conclusion, comment on the following points:

  • CFD tools allow us to predict the behavior of floating platforms taking into account different climatic situations.

  • The behavior of these platforms can be unstable and the position and type of anchors are determining factors in their stability.

  • CFD allows us to reduce the traditional design spiral, obtaining better results before prototyping, saving costs and allowing iteration of designs much faster.
