Moving St. Lawrence Bottom

I’m back and–before catching up on my time off the internet–I need to pack the robots back into Cosmoline and close out some January 2016 dredging business . . . here’s my most recent Professional Mariner article.  And below are some additional photos of the research done in June 2015.

This is what 1100 + cubic meters of misplaced river bottom looks like after it’s sucked up and being transported to another location where scour demands it be added.

And that red boat in the distance is the client, at least the

verifier for the client.

Once in the designated discharge site, hydraulic ram start to press the

hulls apart, and

all that bottom finds itself in gravity’s grip and

tumbles out.

Now only some water remains as the vessel–Ocean Traverse Nord–returns to the worksite and

lowers the arm to suction up another 1100+ cubic meters

 

of gallivanting silt piles, here shown in patches of green.  Notice the darker rectangle, representing the location of the dredger hull.
