Here are a few pictures I took from my phone as I was waiting in line at the port last weekend. The first one is a picture of the back of the ship we are unloading.
The second pic is what it looks like under the crane. The crane unloads the container on the back of the chassis or bomb cart. I then drive the container to the yard and either park the load and get another flat bed or drive it to another crane that takes it off and loads it somewhere on land.
Here is a picture of another terminal across the channel. Actually, I worked at that terminal last night. :)
