Cruise ship engineroom with a massive 6 main engines and alot of life support systems 

Yes they normally hardly know they are on a ship at all. Most refer to it as a boat... There is a possibility tough, to buy a guided tour of the engineroom on some ships.

@@andresteinum Thanks! Ya, even if ppl knew about all the infrastructure on the ship, they don't care. They just wanna have fun. At what stage does a "boat" become a "ship"? LoL.

@@curtchase3730 A boat becomes a ship at 500 tons.

Why would the passengers need to care unless they had a real interest in it? You know how every system in Your Body Works relating to the other systems? Yeah, I didn't think so!

Auxiliary power is taken directly from the main engines. They have a few emergency power generators tough. Maybe I should start including those in my future videos also.

Yes. On this ship it is a special setup, as the scrubbermaker went bankrupt before the installation was finished. So the system has two makers, as a different company finished the installation. All the ships I have videos from have scrubbers Martin.

Hi Socrates. These engines are only power generators. Then this power is used to power two large electric motors who is connected to two propellers with a long propeller shaft. Not needed to have pitch propellers as the electric motors are controlled with large VSD frequency controllers. Dont know how many engineers is working on the ship. Yes they are Wärtsilä engines. They also power the rest of the cruise ship.

On a Cruise ship a very average range is hotel and other mechanical power services consume about a 1/3 of the entire electrical powerload required when sailing at service speed. And I did not see any propeller shaft in this video. Only 6 generator sets. I imagine either it is driven by 2 Azipods or 2 direct shaft props from 2 electric Propulsion Motors.

Thats where the engine guys take their girlfriends..

Usually, two propellers, electric propulsion. These engines purpose is generating electric power.

@@sebastiandanciorogaru1052 So they are not main engine so in the vlog it say six main engine Ive never encounter six main engine on the ship

You could say main engines as there are no other engines. The majority of cruise ships built in the last 25 - 20 years, have electric propulsion,. On older cruise ships you can find classic main engines, usually four, and two propellers.

Yes it is called diesel electric. Even when they use heavy fuel oil (HFO).

Yes

QE 2

something costa

Total efficiency of steam engine including boiler is about 10%. Big diesel engine is about 30%.

​@Tapiokr if there such a thing as push pull propellers why not combine the two technologies?

Modern solution would be combined cycle power plant. The fuel is first used in a gas turbine and the gas turbine exhaust is directed to a heat recovery steam generator producing steam. The steam is used to run a steam turbine on a same shaft with the gas turbine. The turbines turn a generator to generate electricity for propulsion and other uses on the ship. Efficiencies over 60% are achievable this way.

@@Tapiokr Diesel engines of this size have an efficieny of around 45 % 30 5 are small diesel engines or larger petrol engines. When it comes to big crosshead two stroke diesel engines go up to 55 %. In combined cycle systems where the exhaust gas ist used to produce steam and run a steam turbine (which has an internal efficiency of up to 40 %) the efficiencies can reach up to 60/70 %. With a steam engine that would be impossible.

@@jannilshansen6142 Yes, I know, Wärtsilä Sulzer RTA96 efficiency is more than 50% and 100 000 hp. Those cruise ship engines are maybe 10 000 hp each and thats why a little bit lower efficiency.

I don't tell the ship name or imo so make a guess.

So?

@@JimmyCasket02 hows christmas going for you jimmy? Miserable sh*t

It has a big benefit. You can manage the power provided by the engines in a way that all the engines are running at most efficient loads. With a direct propulsion that is not always possible, except you are steaming over long distances what cruise ships do not do

@@jannilshansen6142 yes i know all that, do you think i didnt know ? Im just saying its a bit boring,just sitting there,

@@bonkeydollocks1879 they don’t do jumping jacks when they turn a prop shaft they also just sit there

They are not big Diesel engines but compact medium speed engines to save space. Main propulsion steam plants burns more fuel and are not as efficient as Diesel Propulsion. However a Diesel plant has a lot more moving parts and required maintenance pushing the running costs up. Today you would be hard pushed to find a ship with a steam propulsion plant. Probably the only ones would be Gas carries that can burn the boil off from the cargo tanks in the boilers to provide steam for the turbines.

Gas türbinlerinde modül içinde küçük hacim ile büyük güçler üretilebilir. Bakim gerektirmez, çok yakıt yakar ve yüksek ses oluşur. Jeneratör için uygun bir seçenek veya "combination dizer or gastürbini" (CODOG) gerektigin de hız istendiğinde türbin devreye alına bilir. Bir çok ülkenin deniz kuvvetlerinde bu sistem kullanılır. Ben türbin kullanan sivil gemi bilmiyorum sizler biliyorsanız beni bilgilendirin

These particular engines, Wartsila9L46, 1 MW per cylinder, roughly.

Women don’t like you

​@cipaisone, sir, for your safety, I please ask that you refrain from feeding the trolls as they are kinda like gremlins.

You say as you have a kitten in your profile pic.
