What if they offloaded the containers from the front 1/3 or so and then used a high volume water pump and hose to blast the sand from below the bow?
I think that the combination of making the front lighter and dispersing the sand would make it feasible to tug out.
Just my Sunday thought while reading into the Suez situation.
That's very true and would require the weight of all the individual containers and their location on the vessel to be calculated. A quick look into the ships manifest would make that easy. They have all the weight and location information at their fingertips.
