Interesting barge by the bridge

Shortly before Thanksgiving, I was taking a walk downtown with a friend of mine. We stopped by the South Street Seaport to take a look at the river and saw this barge pushed beneath the Brooklyn Bridge. (The Brooklyn Bridge goes over the East River in New York City.)

My friend Phil notes that this is a crane; the large posts are pylons that sink into the riverbed and keep the crane steady. I wasn’t able to find any references to this barge in five minutes of searching, but I did find this interesting blog about the New York Harbor.
