Earlier quoted context omitted.
Let's get more specific. What is reasonable compensation that should Egypt demand?
A pilot from the canal was on board, how is it not their fault? (Zero compensation)
More likely: Ships are required by rules to have an Egyptian pilot on-board during the passage, and there is limited legal liability for ordinary operating circumstances. That said, if an Egyptian pilot was found grossly negligent of their duties, then they would be liable. However, in most legal systems, this is an exceptionally high bar. And, I assume if you pass the canal, you subject yourself to the Egyptian court system. (Read about the big cruise ship that ran aground in Italy. That story reads like text book gross negligence!)
