About this video:
A ship the size of Norwegian Spirit is estimated to use as much electricity as a small city. And while battery technology is improving at a great rate, you’d still struggle to find one that could allow for longer distance voyages while still powering a city, and fitting on a ship, with space left over for all of the passenger and storage spaces that are needed on board.
The most common power system on ships at the moment is diesel-electric. This means that diesel engines on board the ship produce electricity. This electricity is then used to power the different services on board. This includes powering the propellers or pods. This is a form of indirect drive, where the engines are not directly attached to the propellers to drive the ship.
This is the opposite of the reciprocating engines of old. The old reciprocating engines, and even the first steam turbines were direct drive. This meant that the engines were attached directly to the propeller shaft, or paddle wheel in the older ships, and as the pistons turned, this turned the propeller or paddle wheel shaft.
Direct drive engines are the simplest way of powering a ship, but they aren’t the most effective. It was discovered in some of the earlier steam turbine ships, that the speed at which the propeller was most efficient and the speed at which the turbine were most efficient, were different. This led to serious vibration issues when the ship was run at speed.
Indirect drive engines overcome this problem. Though they are a little more complex and require more machinery to convert the electricity to allow it to run the ship, they are more efficient overall. They allow both the engines and the propellers to run at their most efficient speed by separating the process of creating power from the process of using that power.

Would you cruise on a Nuclear powered ship? There actually was one back in the 1960s - check it out @05:36!
No chance of smoke and soot going into the back pool like on my last cruise.
I thought Elon found you can get power wireless via Starlink? You know the power is just beemed down to all the ships! lol
Yes.
Yes ☢️
Always insightful - informative and presented clearly to grasp
Glad you think so!
Thanks for this information- another interesting and insightful video from you
Glad you enjoyed it!
A fascinating review of a complex topic.
Thanks!
Chris another factual and informative presentation. It will be interesting to see future development on how green technology can be utilise.
Love the bloopers at the end 😂😂😂
The intro has me imagining QM2 running a really long cable as if she was actually Great Eastern on telegraph cable laying duties 😂
This is brilliant!
Another great informative Video ! Congratulations Chris !! It was all very fascinating. Loved the bloopers at the end ! “ Long extension cords!?!” Really Chris , So Cheeky !!😏😂. 🇺🇸🇦🇺! ❤️MikeW.
There's also tecnology that creates a blanket of bubbles underneath the hull, thus reducing the drag and thereby the consumption of fuel for the ship. An example of this is AIDAnova.
That’s fascinating
Already in test and real use in some Princess ships. Air compressors at the bottom of the ship pump compressed air thru strategic holes in then hull to provide a more "slippery" hull surface, less drag, less fuels used.
it's very useful for me
thank you sir
Do you know how large is a single diesel electric generator unit on a modern ship?
One of QE2’s MAN B&W diesel generators was around the size of a London Double Decker Bus. She had 9 of them!!
Nuclear powered cruise ships would be a good idea. The Navy uses many nuclear plants in its ships/subs. The new small scale nuclear plants seem ideal.
I have been on both Coral and Island Princess. They still have the diesel electric engines. Sapphire princess also has the gas turbine engine. 🤔Would a nuclear powered ship need lights or would it just glow ion the dark?😏
You’re right Coral & Island have a dual power plant with Wärtsilä 16V46C diesel engines and General Electric LM2500+ gas turbines.
Yes no emissions means yes to cruising.
If my cruise line starts banging on about Green Energy and being Carbon Neutral, I'm going to book with another cruise line! BTW, there is a reason LNG Tankers are designed the way they are, who would want to cruise on a floating bomb??!!
Oh my goodness what ignorance
Wait, you mean the captain doesn't plug in a bitch extension cord that's as long as the North Atlantic? Are you sure about this??????????
They probably need to stop building cruise ships until a 100% green source of power is implemented. We all need to make sacrifices now. I’ll miss cruising.
