Yes, by the agreement the shipping company has with the Suez Canal Authority, the shipping company is responsible one way or the other even if it's the pilot's fault. The buck stops at there. But the pilots are employees of the Suez Canal Authority contracted out to the ship to guide it through the canal. The shipping company is within its rights to sue the Suez Canal Authority for failing their contracted obligation. It's like when the general contractor is sued, the sub-contractor can be sued if they're the cause of the problem.
