These aren’t dredges-—they’re muck buckets. Totally capable of scooping mud from anyplace except UNDER THE SHIP, where the stuckishness is. Remember how they got the Intrepid unstuck from its dock in NYC when they took it to drydock for a paint job? They water-hose-blasted the muck and mire away. Gonna be interesting to see the next way this can be screwed/unscrewed.
Thank you for the catch.
Blasting the muck out with a water hose seems to be much more appropriate.
Unless the EPA now forbids such silt creating methods (that work) from being used in the Bay.
Or maybe Cashman is one of those connected firms that seem to populate East Coast shipping.
They're clamshell dredges. Once they dredge a channel, tugs will drag/push the ship into it.
