How come America never builds big ships anymore, other than for the military? Cant afford to pay the floor sweepers $100/hr??

It was built for a in Denmark for a Danish shipping company. Maersk is the largest marine container shipper in the world. Most of the larger marine transport companies are based out of Asia and Europe.

WOW

"Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour"

Weird, the site says engine built in Japan but the sign in the second last picture is in Korean...

This may apply to this ship, it does to other big ships. The propeller has fixed blades so in order to go back, you have to reverse the direction of the propeller shaft. However on ships this big and powerful, its not feasible to have a reverse gear.

So they actually stop the diesel and start it back up running in the reverse direction. Thought that was pretty cool.

Like a jake brake?

Not even close. A jake brake works by releasing the compressed air in the cylinders so that the engine is not getting energy from the compressed air on the downstroke.

Most new ships actually use the large diesels to generate electrical power which in turn powers large motors connected to the propellers (screws). The engine(s) never need to be powered down in such a maneuvering situation. Azipod propulsion systems actually have the motor enclosed in a pod which is completely outside the hull and can be rotated 360 degrees eliminating the need of rudders and aft thrusters.

From a full speed (25.5 knots) we can stop in approximately two ship lengths (<2,000 feet!) by reversing the azipods! :Q
 
Given the cost of the thing and the fact that it only needs 13 crew members, I hope they get some seriously plush living quarters.

It was NOT designed for the Panama or Suez canal. It's strictly transpacific.

The goods arrive 4 days before the typical container ship on a China-to-California run. So this behemoth is hugely competitive carrying perishable goods.

This ship was built in five sections which were floated together and then welded.

The ship is named Emma Maersk.

The command bridge is higher than a 10 store building and has 11 crane rigs that can operate simultaneously.

Country where built - Denmark
Length - 1,302 ft
Width - 207 ft
Net cargo - 123,200 tons
Engine - 14 in-line cylinders diesel engine (110,000 BHP)
Cruise Speed -31 mph
Cargo capacity - 15,000 TEU (1 TEU = 20 ft3 container)
Crew - 13 people -- Construction cost - US $145,000,000+

Silicone paint applied to the ship bottom reduces water resistance and saves 317,000 gallons of diesel per year.

Gives a sense of the scale & mammoth size

woah.. $145M?

whats the life expectancy? and how much does it make per transpacific trip?

That is absolutely insane. Is that hard on the propulsion system, or can you stop like that any time you want without consequences?
