500 tons: Water to fill world’s largest at-sea swimming pool
724: Number of hollow 66-ton steel blocks that fit together to form ship’s decks
2,800: Number of people working on ship’s design and construction
Nick KaloterakisName: Oasis of the Seas
Where: Florida
Cost: $1.2 billion
Estimated Completion: This year
The Challenge: Build an 18-story-tall superliner with more outdoor space
When the Oasis of the Seas sets sail later this year, it will claim the record for biggest passenger ship, with space for 6,300 passengers, 2,000 more than any other ship. But it will also claim the most rooms with balconies, the biggest onboard swimming pool, and the first at-sea, tree-filled, outdoor park.
Those features were possible because of the ship’s unique design. Traditionally, the top of the boat is built like one big box, with only a handful of rooms facing outward and an open deck area limited to the bow and stern. Instead, Royal Caribbean engineers widened the hull and split the box in half, erecting two six-story towers of cabins on either side, with enough space between them to fit the football-field-size park.
To maneuver this new giant, three 20-foot-tall propellers pull rather than push the boat through the water. The propellers are mounted on swiveling pods along with electric motors (powered by diesel generators in the ship) delivering the equivalent of 30,000 horsepower. This system is more efficient, because it eliminates the need for a long drive shaft, which typically creates drag under the ship. The propellers can rotate 360 degrees, so they also act as the steering system, allowing the captain to make adjustments in port of as small as one foot. “Ten years ago, we felt that 140,000 tons was as big as we could go,” says Oasis designer Harri Kulovaara. “Now that we’ve got the experience, we’ve taken a quantum leap.”

A tree filled park on a ship - because a swimming pool on a ship wasn't counter-intuitive enough. I know when I feel like a stroll through the park, I want to pay a few thousand dollars for the privilege.
Hopefully they will also be innovative with the lower class cabins. We upgraded when we took a cruise, so I don't have all the details, but apparently the base cabin is not much more spacious than the new Smartcars. Our 'upgraded' cabin was barely adequate, so I don't doubt that the base cabin was pretty awful.
Also, the plumbing required some complex manuvers to get it to function correctly. It's been a while, but it was along the lines of "Open valve A until .... then open valve B and close valve A. Finally ... "whatever, I think you can catch my drift.

Anybody want to start bidding on offshore condos??? Since there very little forest left the next logical step is to star building on the oceans. What would it be like to be born and raised entirely in a contained city floating on the ocean. Could we revolt and start a new country that truly has no borders, move the entire country from the Gulf of Mexico to the South Atlantic????
Omg!!
Bet you I am going to be its first passenger!
Are your stats correct? The Royal Caribbean web site (oasisoftheseas.com) puts Oasis at 220,000 tons, not the 160,000 you printed on page 44. Also, it says 5,400 guests, not the 6,300. If you're including "crew" in that number then it is misleading.
Siress,
I thought your comment was very funny.
It's amazing to see just how far engineering has come. What's even more impressive is the decrease in amount of time it takes us to build these amazing machines. This ship is definitely going to be one of the best and I cannot wait to see it in real life.

Of course, "Oasis of the Seas" was actually built in Turku, Finland. Not in Miami, Florida. Not that it matters, really. Location schmocation. Who cares?
Oh come on Quintus, you know us Euroweenies are all lazy socialists, we don't build ships like this ;)
STX Europe on the otherhand do :)
There is a full sized wooden carousel onboard too. They had it built by from Carousel Works in Mansfield OH. It's going to be installed sometime in April I think. There is one scheduled to be built for the sister ship next spring also.
These new highly advanced ships will have a hull design structure that makes them virtually unsinkable, so they won't need life boats. The maiden voyage will be on a course riddled with icebergs to test this theory out.
Virtually unsinkable! That's a contradiction and not correct! Our seas will take when it wants to. Rest assured if the seas whipped up a storm this boat would sink and or topple. The ship is just beautiful, and if I were to consider a ship cruise this appears to be the ultimate in luxury and somewhat excessive use of materials in order to maximize the benefits for the passengers. The maiden voyage was an resounding success and contrary to some of the negative comments, the green garden and park is very popular as is the boutiques, swimming pools and all the entertainment that is available on board.

When I consider the size of our town, this boat is nearly three times the size and has capacity for more than double our population. This ship is fabulous design and will be the envy of most who cannot afford this luxury.
