The Huron Service Tug

So I went down to Milliken State Park after work again tonight.  I saw on the ais site that there were going to be two ships coming down.  Both of which have appeared on this blog in the past.

 This is the Huron Service/Energy 6506.  They have been anchored here for a while it seems.  They have also appeared on this blog in the past, so not too much in the way of description.

 It is basically a tug/barge combination but I'm not sure it's a dedicated combination like some of the others.

After getting a passenger from the Westcott, here she is pulling away.
