Mega Ship Fuel Efficiency Continues to Increase

Oasis Class Ships

Royal Caribbean has figured out how to make the Symphony of the Seas cruise ship more fuel efficient by consuming 25% less fuel than the slightly smaller Oasis of the Seas and Allure of the Seas ships. The Symphony of the Seas is the largest cruise ship in the world. The vessel measure 1,188 (362 m) in length and has a gross tonnage of 228,081. The vessel is 18 decks high, and can accommodate 5,518 passengers at double occupancy or a maximum capacity of 6,680 passengers, plus an additional 2,200 crew members.

Mega Ship Fuel Consumption

The Harmony of the Seas was released in 2014 and is slightly smaller than The Symphony. The Harmony has two four-storey high 16-cylinder Wärtsilä engines. At maximum speed at 25 knots (46 km/h; 29 mph), The Symphony would consume 1,377 gallons an hour, or about 66,000 gallons a day of diesel fuel. The normal cruising speed for the Harmony is 22 knots (41 km/h; 25 mph).

Oasis Class Ships

The four ships: The Oasis, The Allure, The Harmony, and The Symphony make up Royal Caribbean’s Oasis Class ships. Most ships in this class are closely related in size. Generally each ship is 72 m (236 ft) above water line and 22.55 m (74 ft) feet deep. The width largest with of theses ship are around 60.5 m (198 ft), making them floating cities.

Vacation Hacker Tip

We love the Oasis Class ships! The Vacation Hacker family will sail on The Oasis of the Seas later this year. If you are afraid to go on a cruise or if you know someone reluctant to go on a cruise ship, the Oasis Class cruises should be a great fit! This ship doesn’t feel like your typical cruise liner as it is massive with lots of space and areas to discover. The last time we sailed on The Oasis, we felt the ship move only once. It is great for those passengers worried about getting seas sick too.
