Besides that, new risks associated to this route may push shippers to look more closely to an alternative route. Northern route is much shorter, does not have vessel size limits and it becomes more easier to navigate with global warming. It's not hard to imagine ice class nuclear merchant ships carrying 30-40k TEU there in 10 years.
This is very hard for me to imagine.
The only question is if it is economically viable at current level of technology.
Imagine one of these with stuff on it.
My guess is that if Egypt decides to push responsibility entirely on the ship's owners and operators then it would open itself up to more vocal criticism from other customers afraid of also being sued for mistakes caused by Suez being unfit.
At one billion I reckon its a matter of foreign relation so they won't be ripped off in a dark back alley.
And in return they receive protection from other claimants, who will have to bear their own risks no doubt.
Especially if it was force majeure as the GP implied.
