Not so sure about that collapse, the keel of the ship is currently supporting all of that weight and seems to be holding up just fine. It's essentially a suspension bridge at this point, but I agree that it is probably better to unload evenly, however, that will add another very substantial time penalty. If the ship would break (which I have no idea at what load imbalance that would happen) there would be a delay a lot longer so it may be worth it to play this extra safe. But there is a very large amount of pressure on the people there to get this resolved.
