I see you would reject a straw because it was not meant for in-water rescue, Stephen. If one had simply wrecked a thruster or two in avoiding/hoo-harless-recovery from the grounding think how much better for everyone's economy (if we ignore the effect on balance of payments that is).
The BBC have just told us that she is now on course again but still aground! A concept for which no charter party has yet devised a clause ("Always afloat or safely aground"/"Safely aground, pointing in the right direction"?) .
If it worked then it would be fine. The thing is, it wouldn't work. You have to assume that there is clear water on one side and then the sand is other the other.
The good news is that the ship underway... I hope no more than 6 knots! Head for Port Said. Underwater survey and then see where she goes next... Rotterdam for discharge and drydock or take her to Alang!
