Factory ship
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.
Contemporary factory ships have their origins in the early whalers. These vessels sailed into remote waters and processed the whale oil on board, discarding the carcass. Later whalers converted the entire whale into usable products. The efficiency of these ships and the predation they carried out on whales contributed greatly to the animals' steep decline.
Contemporary factory ships are automated and enlarged versions of these earlier whalers.[citation needed] Their use for fishing has grown dramatically. For a while, Russia, Japan and Korea operated huge fishing fleets centred on factory ships, though in recent times this use has been declining. On the other hand, the use of factory ships by the United States has increased.[citation needed]
Some factory ships can also function as mother ships. The basic idea of a mother ship is that it can carry small fishing boats that return to the mother ship with their catch. But the idea extends to include factory trawlers supporting a fleet of smaller catching vessels that are not carried on board. They serve as the main ship in a fleet operating in waters a great distance from their home ports.[citation needed]
Fish processing ships consist of various types, including freezer trawlers, longline factory vessels, purse seine freezer vessels, stern trawlers and squid jiggers.
A factory stern trawler is a large stern trawler which has additional onboard processing facilities and can stay at sea for days or weeks at a time. A stern trawler tows a fishing trawl net and hauls the catch up a stern ramp. These can be either demersal (weighted bottom trawling); pelagic (mid-water trawling); or pair trawling, where two vessels about 500 metres apart together pull one huge net with a mouth circumference of 900 meters.
A freezer trawler fully processes the catch on board to customers’ specifications, into frozen-at-sea fillet, block or head and gutted form. Factory freezer trawlers can run from 60 to 70 meters in length and go to sea for six weeks at a time with a crew of over 35 people. They process fish into fillets within hours of being caught. Onboard fishmeal plants process the waste product so everything is utilized.
The world's largest freezing trawler by gross tonnage is the 144-metre-long Annelies Ilena ex Atlantic Dawn. In 2015, the Annelies Ilena was detained by the Irish Navy and the Sea Fisheries Protection Agency for breach of regulations. The owners were subsequently fined 105,000 Euros for illegally fishing in Irish waters. She is able to process 350 tonnes of fish a day, can carry 3,000 tons of fuel, and store 7,000 tons of graded and frozen catch. She uses on board forklift trucks to aid discharging.
