Interestingly enough, the Wikipedia page for this ship says it does have two 2500kW bow thrusters. I imagine if they were worth much in this situation we wouldn’t be talking about them, though.
which is not going to do much here. It seems the trouble with a lot of solutions - the tugs can probably tug with a force of something like 600 tons combined but the ship weights 220,000 tons which is like putting a force of 5kg on a 2 ton car which is stuck. Probably not going to budge it.
Really you want something which will shove it with a force maybe 10% of the weight, say 20,000 tons but there don't seem to be many of those lying around.
I wondered if they tied a cable from the ship to one of the other large ships nearby and fired up the main engines if that could do something?
