Concrete submarine yacht hull, a concrete submarine yacht hull, is designed to recieve a similar level of maintainance as submarine tunnels and bridge foundations do. This means it can stay in water for decades without being taken to drydock or marina - this lowers operation cost compared to normal yacht signifficantly - see more (concretesubmarine.com)

Yacht submarine hull thickness

2008-03-08T13:19:00.000-08:00

Yacht submarine hull thickness, what differs a surface yacht most from a submarine yacht is hullthickness. In a surface yacht you go for thin walled lightweight hulls - while you go for thick and pressure resistant hulls in a submarine - thick and pressure resistent walls are a natural domain for structural concrete building - yacht submarine hull thickness

concrete versus steel in submarine yachting

2008-01-06T04:55:00.000-08:00

Concrete allows to build a thick walled, streamlined, pressure resistant, maintainance free, submarine yacht hull in a way that you could never be performed with plate material like steel. Nor composite materials. See ( concretesubmarine.com ) for details.

Concrete versus steel in submarine yacht building

Experimental concrete in submarine yachts

2008-01-04T11:39:00.000-08:00

I do not recommend any special concrete for building the hull of a concrete submarine yacht. The most important thing is that the pressure resistance of the concrete is "forseeable" and this is exactly what you get with normal concrete forseeable results. So the recommendation is stay away from experimental concrete.

FE Analyze concrete submarine yacht hull

2008-01-04T05:11:00.000-08:00

Hello Wil,

...The submarine steel pressure hulls are not only calculated for linear stress (some private people do so) but also checked for nonlinear stability failure (Buckling - sudden crash) this is very important because especially this inexpensive home made shells with no or less frames tends to buckle long ago befor the stress limit is reached. So for steel hulls a FE-analysis is highly recomended.

But Your hull has a very high thickness to diameter ratio so I would not believe that the will buckle at all. Due to the very smooth shape every cross cut is more or less a perfect circle and can stand for its own... what helps very well to deal with the pressure load.

So without sail and viewport cutouts such a shell would withstand external pressure until the concrete would reach its pressure limit.

The calculation for such a perfect rotational shape could be made with pen and paper and I'm sure You have done this very well and carfully.

B U T - the restrictions starts with leaving the perfect issue...

The sail is normally the biggest disturbance in stress distribution, followed by the viewports. An other very important point is the accuracy of roundness You are able to reach

... I know that there are special element types with special formula to take into consideration that the steel grid will take all the tension and the concrete can brittle and so one... I "simply" have to find out how it works in detail...

By the way .... are You able to make some practical test later to compare fist calculations with experiment? I would feel much more better with some hard facts behind the calculation -

submarine yacht how deep can a concrete hull go

2008-01-02T08:51:00.000-08:00

All that is below 300m should be considered "unproven territory". For a hull of the make of the prototype i would bet on a destruction depth of 1200m (without viewports)

Concrete Submarine Pressure Hulls

Concrete submarine pressure hulls in marine environment in use today - proved for decades...
To give anybody who is interested in concrete submarine yacht construction a clear idea what is the status of modern concrete construction in marine ambient i put a couple of photos together to make my point clear that a concrete submarine yacht hull is not a highly experimental issue - In contrary - submarine concrete hulls are in use today all over the world - just in other fields of engineering...

So- please guys do not ask any longer questions like: "can concrete float?", "will concrete melt away in saltwater ?", "Will a concrete submarine have cracks and let water trough like a sponge? - just relax and think about the fact why the guys that build the things shown below sleep very well and trust concrete as mankinds most used and tested building material.

Statoil's massive concrete based Heidrun platform. The legs of this platform reach over 100m down into the sea. Basicly this floating city is based on the fact that a concrete hull can withstand the ocean pressure stroms and waves all the way from surface to 100m depth during decades - without any alteration.

Inside the concrete leg of a drilling platform. (Troll Platform) Those engineers at the moment of the photo are tecnically "dived at 300 m protected from water pressure by a submarine concrete hull" of collosal dimension that stands vertically instead of horizontally - just flip that platformleg (in your mind) 90 degrees and add a propeller - you have a giant submarine of 24m diameter with 1m wall thickness and 300m length. This is not a new horizon tecnically speaking - it is just to see things from a slightly different angle. By the way my prototype submarine had a wall diameter ratio of almost exactly the double of troll - so it is good for water pressure at 600m including a similar security factor.

Grande Dixence, on the river Dixence in Switzerland, concrete dam. It was built between 1953 and 1961 to a height of 285 m (935 ft). Concrete at the foot of this dam holds a watercolumn of 285m - equivalent of 285m dive depth in a submarine.

Golf of Corinth Greece, the legs of this bridge go 70m down to the ocean floor. They where built at sea in floating status and do rest on ocean floor with very little force to enable the bridge to move in case of earthquakes - so this bridge is founded on 70m deep dived submarine concrete hulls.
