Very Informative. I am a regular listener of the podcasts.

Looking forward to Dr. Martin Stopford's Maritime Economics 4th edition.

If the main objective is really zero emissions and not the all important cost, Why not consider the obvious solution which is nuclear propulsion and generation For Merchant ships?? The technology is there and well known, many nuclear powered aircraft carriers, ice breakers, submarines and even cargo ships (Savannah, Otto Han, ect..) have been operating at sea continuously for several decades without any radiologic pollution problems, even when catastrofically lost at sea (like the Thresher and Kursk). Designing, building and operating a nuclear powered container ship, tanker or bulk carrier has already been done long ago and should not be any problems in 2024, no new technology to figure out, its alredy there. Training officers and crew to operate a nuclear powered ship should not be more difficult (and probably easier) than training for navy officers and crews to operate their nuclear aircraft carriers and submarines or for Russian merchant marine officers and crews to operate their nuclear ice breakers, all of which have been no problems since the nineteen fifties and untill now. Of course, the price of a nuclear merchant vessel properly designed, built, manned, operated, certificated, insured, maintained, etc etc… will be very high and such a ship cannot be safely operated by an underqualified crew of 15 people….. However, contrary to the alternative fuels solutions which will anyway still continue to produce at best quite a lot of CO2 and other nasty emissions, a nuclear merchant ship will produce zero CO2, zero sulphur, zero NOX, zero particules, even zero water, in fact nothing at all and will not require any refueling for several years of continuous operation Furthermore, the global cost of nuclear fuel refill for a nuclear ship after several years of operation should be much cheaper than the cost of alternative and expensive fuels and other emission control chemicals and equipment used for the same operating time, no need for shore power while alongside, etc etc., after all, France has produced 70 to 80% of its total consumed power by nuclear plants and without using a drop of expensive fossil or green fuels during the last 40 years with a price almost 4 times lower than Germany In my humble opinion, if we are really serious about a quick and efficient route to zero carbon and emissions in general, nuclear is the only solution for the time being, on shore like on ships, which, contrary to planes and cars, can be easily built with nuclear propulsion and generation. This is the 2 cents of an old retired merchant marine captain and chief engineer

Very interesting, thank you all. How would the ship owners (managers) consider the different regulations coming from EU, IMO, etc.

Instead of monitor the ships, simply monitor the petrol companies and force them not sale high sulphur petrol that's all you don't need to monitor the ships, don't let high sulphur petrol in the market that easier for the whole world, unless you just want to fuck our minds 😂

Thank you. It is a great tool

great to be a part of this seminar

In my view, the onshore power supply for ships in the world's most important ports is paramount to reducing the GHG, mainly for the cruise industry, whose ships spend a considerable time in those ports.

How It works?

Awesome work DNV team !

せんしゃって言ってるように聞こえるのですが、船主のことでよろしいのでしょうか？

Please may I ask how do you test if a submersible is Able to be commercially used ?

Eliminate the music!

Another as presentation for tanker isolating valve for main fire line is outside of poop deck. But my ship isolation valve located at upper deck inside of accommodation. Is that an NC also sir?

May i ask: as solas require capacity of emergency fire pump is not less than 40% of fire pump and not less than 25 cm3 with 2 hoses. Exp: my ship main fire pump is 140cm3. Emergency fire pump is 48 cm3. So is that an NC?

The e-fuels will most likely have a well-to-wake CO2 factor of close to zero. Given the energy that will be required to set up the infrastructure for these fuels, shouldn't the resultant CO2 emissions be included in these factors?

This is extremely informative and a huge developement in regards to maritime emission reporting!

Excellent thank you

Wow! it's awesome!! I want to know how to make 3d scan using a drone.

how does the ventilation of the foil effect drag? is it increased or decreased?

Great documentary on Maritime Cyber Security 👌👌

Personally what I use is SurveyTime, I get $1 USD with each survey I complete and the payment is instant after I complete it, the page is surveytime.me , It takes like 20 minutes, but its much better than other scammy websites and I havent got any issues :)

Is there any of this ships sailing ?

Very nice video but to link the tip vortex ventilation to the actual foil ventilation is misleading. The tip vortex is ventilating because somewhere downstream it connects to the free surface allowing the core to ventilate. The ventilation creeps forward as the waterflow speeds up. As the flow speeds up further eventually the pressure drop on the upper surface of the foil is sufficient to trigger ventilation from the surface. It is important to note that the two ventilation mechanisms are separate and occurring at different speed.

What about small vortex generators along the foil?

👏👏👏👏👏👏👏👏👏👏👏👏🇧🇷

I am surprised that no mention was given concerning the risk mitigation to cyber threats in this project. It is, obviously, a rich target for hackers.

very nice project.

Nice good video

We were privileged to have Knut deliver such an insightful Keynote Address at our forum. And we would like to thank DNVGL for your support of this pioneering initiative to deliver the first large scale digital shipping conference. The result was overwhelming, 3,044 registrants from all over the world, 96 speakers, 36 listed shipping companies with their top executives, DNVGL is always at the forefront of new initiatives and innovation and we at Capital Link are grateful for your support.

Great course

Oh wow, impressive how a ventilated vortex can cause the entire lifting surface to also ventilate. Does the water downstream fall downwards vertically to allow for this?

While giant, natural gas burning ULCVs are a good idea for the near future; I believe modern naval engineers must look to the past if they truly want a "Green" ship of the future. I believe we must utilize the power of the wind along with firm plastic or metal sails long/narrow hulls, auxiliary electric power plants, emergency high efficiency coal burning boilers, and remote control technology. (basically a modern twist on 19th century Clipper technology) From all that I have said up above, what career do you think I pursue? How old do you think I am? I am curious because I think you will guess I am far older than I truly am. Please respond, it would greatly "make my day" if you did. Also, please do not steal my ideas if you read this comment; it would be most inconsiderate if you were to do that for I take pride in my ideas.

A link to the project could help us share our team's study in digital twin

I am failing to see the "ventilated tip vortex" mentioned at 00:40 . Would you please explain what do you refer to precisely?
