If this is any help as to what i said guy's it might help yous i am not any professional on this site i just love the site here you go then ? Launch of ferry hull then roll over at Conrad Industries

Just watched a video on youtube how its deon (NOTE NOT) that particular (VESSEL) but another one some where else they slid the very bottom of the hull into the water down the ramp's like a normal launch ? it was air tight two tug's pushed it to the docks ! where on the dock's 2 very large cranes lifted it over right way up she lay down into the water like putting a baby into it cot really interesting no stress on the hull at all

Andrecas, I do expect she'll be upright by now... :)

Yeosu is a bit off my usual ship spotting track, but I might drop by just to see if they have some other ship upside down...

Cheers

Vlad

@ Vlad.... Any new visit planned for Yeosu shipyard...? Presumably vessel now "right side up".....?

Challenge yourself @Vlad :)

Sophie, that was great! Even if the mystery remains, I just wonder if I could have the courage to contact the yard to ask some questions... I probably wouldn't. :)

Cheers

To satisfy my and everyone's curiosity, I made a phone call to that shipyard, truly. A gentleman who is assumed as an owner of the company was reluctant to explain the reason why the vessel was upside down, even though I asked him very politely and gently. He just told me that he didn't get me properly and hung up the phone. So, it might be left as a mystery. Though, it's okay, sometimes we need sth unsolved in this world!

I should imagine the hull will be devoid of all machinery, it will however have it's ballast tanks/void constructed and secure as in normal construction.
The hull is then launched upside down and whilst in the water slowly capsized/righted by means of manipulation of ballast tanks/void spaces. Now righted, these spaces can then be pumped out using compressed air and the vessel properly refloated.
Fitting out would then continue as normal.

I know some shipyards that build the hulls upside down and turn them over later on, mcduff shipyard has done it with a few of the tugs they have built over the years.
even Damen has done the same with some vessels.
usually smaller vessels will be built upside down thats the hull only and turned over inside the building hall.


but a vessel of this size i have not yet seen.

Well, I didn't even know who builds all those small river etc. ships as I'm more familiar with more "industrial" shipbuilding. Perhaps it's more common in those small "boutique" shipyards?

I wonder, if this method is more economical, more easy, etc..why is it not more widely used? Till this photo ,this is the first time I have heard or seen about it.
best regards for a better future and a more healthy world.

Doubt it. It's far more easy to launch the hull upside-down and rotate it while afloat.

Hi Tuomas, Youtube video you've posted is very interesting. Perhaps once the sister ship will be launced, the one upside down will rotate as in the video and will take her place?

I'd like to continue with my penny's worth - where will they put the garden? Perhaps a sunken garden on the midline midships.

Here's a pretty interesting video from the second world war. Obviously they are not using the same method here, but assembling the hull upside-down is not a new invention:

I recall seeing some smaller yards launching vessels upside down and then simply righting them once afloat.

I'm sure there's a clever way of doing this. Anyway, Here's my 2 cents thrown into the mix..... my guess is they will launch "ship" upside down. Once in the water, use either shore cables or floating crane, or some other means to upright hull ensuring a "soft landing"... (A capsized ship floating upside down cannot sink. While it remains afloat a capsized vessel will usually contain a large volume of air). I think what we are looking at is an empty shell (hull). The deck is attached (making it air tight). There are no components installed, such as railings, winches, engine, etc. Once upright, presumably hull will be pulled back onto slipway for completion...?
(Looks like a sister ship to the right in final stages of completion..?)

The haven't installed the blades on the wind turbine yet.

Maybe they have started building ship-houses !

Maybe it won't be righted. Perhaps this is a new type of dwelling.

It is a real mystery how they manage to turn the hull upright again. There isn't any element that can help to understand...Very intriguing shot.

Thank you all for your comments.

That's is really a good question, how do they turn the hull upright again - and I, too, am not convinced by my own thoughts on the subject...
Launching the hull devoid of any major machinery, the way it's now? The same type of ship on her right hardly looks like a self-righting design...
Use a floating crane? I see no lifting eyes/fixing points for hooks...
Maybe I'll think of something better.

Until then, stay healthy!

Hi guys remember this is not a 6 ft. wooden dinghy but a steel ship with engines,pumps ,motore etc bolted down but not to be hanging from the deck now a ceiling, the weight of this machinery hanging onto bolts , bolts designed to hold down and not to be used to hang from. Unless the vessel is just an empty hulk devoid of this tons of weighty machinery.
Even turning an empty hull is rather a delicate operation, still not convinced about the various answers presented.
regards and keep healthy my friends.

It's on the slip so possibly self righting

Great! Vlad,but i can´t help to ask: how turning upright it again, perhaps a partial launching and a floating crane?
Best regards

Gracias, Longui!

Cheers

Vlad

Very interesting shot. Thank you very much lappino.

Toma muy interesante, Muchas gracias lappino.

Thanks for your comments, Emmanuel and Pieter.

Yes, it's like you said, Pieter. In this case, it's for coating purposes, since there is very little space under hull on the slipway to do it properly.

After that, the ship is turned upright again, and completed on the even keel.

Cheers

Vlad

An easy way to repair bottom damage, certainly if you only have a slipway available.

Most strange my friend, you have come up with some really strange interesting photos in the past my friend, but I think this tops it all. any explanation as to why and how it will be launched?
Keep positive and stay healthy my friend
Thanks for sharing.
best regards.
