The World's Largest Cruise Ship and Its Supersized Pollution Problem (theguardian.com)
An anonymous reader cites a report on the Guardian: When the gargantuan Harmony of the Seas slips out of Southampton docks on Sunday afternoon on its first commercial voyage, the 16-deck-high floating city will switch off its auxiliary engines, fire up its three giant diesels and head to the open sea. But while the 6,780 passengers and 2,100 crew on the largest cruise ship in the world wave goodbye to England, many people left behind in Southampton say they will be glad to see it go. They complain that air pollution from such nautical behemoths is getting worse every year as cruising becomes the fastest growing sector of the mass tourism industry and as ships get bigger and bigger. According to its owners, Royal Caribbean, each of the Harmony's three four-storey high 16-cylinder Wartsila engines will, at full power, burn 1,377 US gallons of fuel an hour, or about 96,000 gallons a day of some of the most polluting diesel fuel in the world.
A 747 burns through 3,600 Gallons of fuel per hour for just over 416 Passengers. This ship burns 1/3 of that for nearly 9000 people.
1. Your math is wrong. It's actually 1.14 gallons per passenger per hour.
2. As others have noted, the measure of productivity is passengers per mile, not total occupants including crew per hour.
3. The true figures are here.
... Its bunker, not bumper fuel, and its the sulfur thats removed from refined oil products, not sodium. There is no compound known as sodium dioxide, but i'm thinking you mean sulfur dioxide.
