Here's what I assume to be a refrigeration trailer waiting for a truck cab at a loading dock on Harbor Island. Walking by this thing, I was struck by the strong geometry in the refrigeration gear, and here's the result.

I remember reading somewhere that some shipping containers require power (like this one) for things like climate control, but many don't. A lot of logistics go into loading a cargo ship, and one of the details is how many containers require power. Apparently, only certain areas of the cargo hold can provide power to containers, and the ship can only generate so much electricity, so that must be taken into account when planning how to distribute containers, and which containers will be carried on which ships.
