Unpopular opinion: The stats about cutterhead wear rates from that 2023 USACE report on the Mississippi River dredging projects surprised me more than I expected
Came across a DOI paper that claimed a 30% increase in cutterhead lifespan using those new carbide tipped teeth on the Lower Mississippi, but my shop's experience with the same setup on a rocky section of the Missouri only showed a 12% improvement, so which data set do you guys lean on when quoting jobs for clients with mixed material conditions?

Oh man, I've been there. I'd lean on your own field data from the Missouri job since mixed conditions always screw up the lab numbers.

Read this thing from a retired USACE guy on a dredging forum who said those carbide teeth are amazing in clean sand but fall apart on chert and limestone. He had photos of them chipped up after just 8 hours in a New York barge canal job. So I think your Missouri data is way more real for mixed conditions like you see on the Mississippi. Lab reports always run on perfect scenarios with uniform material, which just doesn't happen in the field. Id trust your own numbers every time for quoting.
