"Monster Ships" is a British documentary project about the world's largest ships that sail the waters of the World Ocean and help deliver priceless cargo, ensure communication among ice, drill oil wells, protect state borders, and, of course, catch fish. Some vessels are so enormous that they are home to over 1000 people who have their own shops, cinemas, and tennis courts. And others are capable of generating their own energy, essentially becoming "eternal engines" for themselves.
