This is why the bow will tend to rise when a ship is moving quickly the stern can bee seen as being sucked down almost. Water moves fastest near the stern of the boat. Brenden Greely of The Financial Times had a good possible take the other day on the Bank Effect:Įssentially, Bernoulli's Principle makes these large ships susceptible to jack-knifing in narrow canals.įaster moving water creates a lower pressure zone. One missing part of the discussion is how this large ship got stuck. It will take specialist dredging equipment to start removing this sand. You can dig out the sand around the ship but there is a huge amount that the ship is resting on. Again the infrastructure to do this rapidly doesn't exist. That leaves dredging the sand under the ship. It won't be easy and will likely take several weeks to unload a significant number of containers, the ship and containers will be damaged in the process. The easiest way to remove containers will be using cutting equipment, winches and possibly explosives. You could build a custom crane barge but that would take at least a month to fabricate and get to the site. There doesn't exist any infrastructure which could get to that location and lift off containers. You can maybe unload a few per hour with helicopters. And unloading them will be a slow process. Containers can be unloaded but again the lightest will be at the top so a significant number will need to be removed to make a big enough difference.
It will be weeks before this ship is free.įuel and oil can be pumped out but that only makes up a fraction of the total weight of the vessel.
