Harmony of the seas -- engines??

Anyone know how many?

I see 13 total on one site and 15 on another :confused:

Six main diesel engines.

Installed power:

• 4 × 13,860 kW (18,590 hp) Wärtsilä 12V46D[2]
  
• 2 × 18,480 kW (24,780 hp) Wärtsilä 16V46D[2]
  
• 
  

Propulsion:

• 3 × 20 MW (27,000 hp) ABB Azipod,
  
• all azimuthing[2]
  
• 4 × 5.5 MW (7,400 hp) Wärtsilä CT3500
  
• bow thrusters[2]
  

Six Generators (as they aren't called engines anymore as they don't direct drive propulsion but generate electricity for the Azipods and thrusters).

Each capable of generating 92MW.

60MW is used to drive the 3*20MW azipods.

22MW for the 4*5.5MW bow thrusters

So you can see on these mega ships by far the majority use of the generators is the hotel side of it, a very large amount being used for aircon!

Wow ..thanks everyone!!!

Ah, no. As the previous poster noted the output of the generators, the total capacity of all six combined is 92Mw.

The diesel generators are not run at more than 80-85% of capacity, and in port the ship runs one generator, so hotel load would not exceed 15.5Mw (85% of one large generator), and in reality is more like 10-12Mw. So, at sea, at full speed, hotel load is about 16% of the power being generated.

But, of the 10-12Mw of hotel load, about 8Mw would be A/C plant.

OP, what were you counting when you thought there were so many "engines" on the ship? Just curious.

If the Harmony's engines were each rated at 92Mw, they would be some of the largest marine diesels in the world, as are used on the largest container ships. Unfortunately for cruise ships, these engines are 90 feet long and 44 feet tall, which would raise the engineering spaces from 2 decks to over 4 decks, and push the crew areas higher in the ship, and push passenger areas out, which is why these large, slow speed engines are not used on cruise ships, but more, smaller, medium speed engines that can fit in lower engine rooms.

They may have been counting the total of the main generators, propulsion motors and maybe even backup generators.

I'm not sure how they would come by a number "on each side" like they did, so I'm thinking they were counting ventilation gratings, where you can hear the fan roar, and think they were engines.

If you would like to see what the engines look like (well, actually they are the ones on the Indy, but similar), look at post 8 on this old thread http://boards.cruisecritic.co.uk/showthread.php?t=2043327

For some reason, I can't post pics onto this thread like I used to:rolleyes:.

This is what we were given at the meet Capt meeting. I can see the mistake now. The HP adds up but each should read total.

Harmony of the Seas is powered by three 18,860kW Wärtsilä 16V46 16-cylinder main generator diesel engines and three similar Wärtsilä 12V46 12-cylinder engines producing 13,860kW each. which comes to 98?
