How are they going to do this? Three Ellicott 370HP dredging machines will provide the backbone.
Think of these as big floating vacuum cleaners with a huge rotating bristles. Each dredge has a capacity to pump up to 5,000 gallons per minute water with up to 20 % solids a distance of 6,000 feet. Basically, one dredging machine can move 3,000 cubic yards of material during 24 hours of operation.
The 'bristles" are a 32" diameter cutter head which will allow dredging to a specific depth. A GPS on board will allow the dredge to be placed with precision. Bathymetric surveys will be utilized on a monthly basis to verify progress of the ash removal.
These dredges are still small enough to be hauled easily to different locations.
