Using a compact CO2 refrigerating plant to chill a fish catch in an environmentally-friendly way

With a length of 45 metres, F/V Northern Defender, one of the trawlers in the fleet belonging to Global Seas headquartered in Seattle, Washington, delivers its catch to a shoreside factory for processing. She normally operates in the Bering Sea off Alaska and returns to port with up to 340 tons of pollock. For the fish to stay fresh during the voyage of up to several days, it is chilled with seawater at zero to minus one degree Celsius.
