The German factory ship Kiel NC 105

A factory ship, also known as a fish processing vessel, is a large ocean-going vessel with extensive on-board facilities for processing and freezing caught fish or whales. Modern factory ships are automated and enlarged versions of the earlier whalers, and their use for fishing has grown dramatically. Some factory ships are equipped to serve as a mother ship.
