The second to last image is interesting because you can see that the water line is not level along the side of the ship - perhaps its momentum caused it to run up a bit? It's hard to tell the scale but they may need to dredge a volume of sand/dirt (estimating) 10m x 60m x 100 m or 60,000 m^3. If they get the dredgers in place they might be looking at 3 days of dredging, if my estimate of 20,000 m^3 per dredger per day is correct. What a project.

I'm not even going to guess at how long this will take.
