This is another view of the Avamporto di Levante cargo port. The cranes that we see here serve one of the busiest ports in Europe. I started reading through the annual report of the Port of Napoli, but oh so MANY statistics, so rather than sit there for a week to caption one photo I'll steal the crib from Wikipedia based on the 2013 report:
- The container terminal has 70 berths, a storage capacity of 1.336 million square metres, 11.5km of docks, and can handle about half a million standard containers.
- There are four terminals for commercial cargo; one for timber, one for cellulose (presumably for paper, cardboard, etc), and two for cereals.
- There is an automobile terminal for roll on, roll off traffic heading to (for example) Sicily. It can store 8,000 cars and can handle over 900,000 movements per year.

And, of course, many, many cranes to support all of that.

In addition to that there is the passenger terminal, but that's not what we're looking at here.

I imagine that there are some service facilities there too, since I can see two hydrofoils sitting up out of the water, as well as what looks like a burnt ferry with some scaffolding around it. (You may not be able to see these clearly in the published image.)
