The cruise ship's gas mileage is 437 gallons per mile
The cruise ship MS Oasis of the Seas gets a gas mileage of 437 gallons per mile (gpm), which is equivalent to 12 feet per gallon. This figure may seem low, especially when compared to the mpg ratings of cars. However, it's important to consider that a cruise ship carries far more people than a car. When fully occupied, the Oasis of the Seas achieves 14.40 mpg per passenger or 19.36 mpg per person, including the crew.
The ship's power comes from six medium-speed, marine-diesel generating sets. These include three 16-cylinder Wärtsilä 16V46D common-rail engines, each producing 18,480 kW (24,780 hp) or 18,860 kW (25,290 hp), depending on the source. There are also three similar 12-cylinder Wärtsilä 12V46D engines, producing 13,860 kW (18,590 hp) each. The total output of these engines is 97,020 kW (130,110 hp), which is converted to electricity for hotel power and operating lights, elevators, etc.
The fuel consumption of the main engines at full power is 5,213 litres (1,377 US gal) of fuel oil per engine per hour for the 16-cylinder engines and 3,910 litres (1,033 US gal) per engine per hour for the 12-cylinder engines. This amounts to a significant fuel consumption, especially when considering the size of the ship and the number of people on board.
The Oasis of the Seas is a large cruise ship, with a gross tonnage of 225,282 and a double occupancy capacity of 5,602 passengers in 2,801 staterooms. The ship features 16 decks for guests and 24 guest elevators. It is part of the Oasis-class of cruise ships, which are some of the world's largest passenger ships.
