The whole dock is probably damaged. Weight of those cranes is not enough to tilt ship like oasis. Something else has failed before those cranes. Good idea to reschedule the big dry dock, not sure if they can do it there. If there is salt water in the electric motors, transformers or other electric stuff thats going to be pain in the ass to fix. And i would also be worried about the condition of propellers. If whole dock has collapsed somehow they can be damaged. Not your everyday spare parts.
