Thanks for the two barges.
In order to seriously estimate whether the barge will be able to support the weight we’ll need to do a stress analysis on it which will require from your side the 3D CAD model in step or iges format.
If you cannot provide me with that I will need to first make the 3D model myself either in Catia or Solidworks and later create the FEA model and do the required analysis.
Another big concern it’s not the peak load on the barge but also the fatigue loading on it, especially when it comes to the friction between the barge and the causeway.
The causeway’s surface will also be of concern due to the fact that the Hertzian contact between the barge and the causeway will produce heat and material degradation on both sides.
An additional loading to be considered is vibrational and resonance forced which can be done with the same FEA model, but different loading condition.
