Since you have experience in boats of this magnitude, did it make sense not to have tugs minding the ship until it passes under the bridge since it's pretty obvious through common sense what the alternative is when there is a catastrophic engine failure? Would tugs even help if they'd been around during a catastrophic failure of the boat engine(s) making my question a stupid, ignorant one?
I don't know the rules for the Port of Baltimore, but tugs aren't generally required for channel transit. It's the berthing where tugs are generally used: the ship needs lateral thrust to lay alongside a pier or quay wall. Some ships have bow thrusters or APUs but a ship this size would definitely have tugs for the mooring.
