Since we were on the subject of big machines yesterday I thought I'd bring this one up- the world's largest cruise ship called Oasis of the Seas, which will be completed this year. This thing is massive. It will weigh 220,000 tons. For comparison, yesterday's giant earth moving machine weighed "just" 45,000 tons. The next biggest cruise ship is 150,000 tons. Another comparison: The USS Ronald Reagen, which is the world's largest Aircraft carrier weighs 95,000 tons.
1,181 ft (360 m) long

8 Wärtsilä V12 Engine @ 17,500 hp each
