Inside the largest personal submarine (Original sound was muted by YouTube). Germany - 2015

The following footage shows two trips of the private submarine "Euronaut" to the wreck of "Sandtrans" and to the unnamed wreck field off the German island Darss in Baltic Sea. The trips took place in july and august 2015 with a purpose to train the crew.
"Sandtrans" was a Danish suction excavator, which sank on september 15th 1978. Overall length 60 m (197 ft) and lays keel up with the max depth of 12 m (39 ft). Min. depth at the highest point 5 m (16 ft). The typical visibility is below 5 m. The day we visited the wreck it was even much worse.
"Euronaut" is a private project of a research and diver support submarine around Carsten Standfuss - a German naval architect. It has been designed between 1988 and 2000. Then it took another 12 years to build it on holidays, weekends and after work. Most systems on board are second hand and homebuilt.
The sub has overall length of 16 m (52 ft), surface displacement of 57 tons and is capable of diving up to 250 m (820 ft).
Transit speed is up to 6 knots with a 190 hp diesel engine. Electric drive measures 40 kW.
The life support system provides air for the crew of six persons for a week. The diving chamber allows saturation dives to the depths similar to the operational depth of the submarine.

[@Wrackzeichner]

It was designed for 1 week submerged operation

[@SuperMrminecraftdude]

+Deep Blue Sea 1week?! Thats not bad! Was expecting something like 1 day or so, i dont know a whole lot about submarines...

[@SuperMrminecraftdude]

+Deep Blue Sea when that week had passed can you then just resurface and refill the tanks and then go back down or do you need to go to a harbour to refill the tanks and all that necessary stuff? :D

[@Wrackzeichner]

The underwater endurance depends rather on amount of CO2 absorber in scrubbers, of O2 in the cylinders and of food. All these problems can be solved with additional storage of oxygen on deck and soda lime in the bilge canisters or microwave food in the storage boxes. For the rest there is an electric generator, air compressor and a freshwater plant.

[@puffinus_puffinus5685]

I hope I'm not repeating a comment here, but how does the oxygen system work? Is there a CO2 scrubber & O2 tanks? Sorry I'm new to submarine technology and was wondering if it was a whole computerized system. Keep up the inspirational work!

[@Wrackzeichner]

This is a simple and "stupid" system with CO2 Scrubbers all over the boat (2 large ones in the galley, another 2 in the diving chamber plus two small in the Control Center) and with some O2 tanks with the constant flow of oxygen into the main compartment (typically 0,25 l/minute per person). In the diving chamber you have to set your O2 constant flow according to the diving tables in the corresponding depth and you have to keep an eye on the O2-Sensor, so you don't pass the border, where Oxygen becomes toxic. Everything is manual. There is no computerized system in response of any vital function of the boat.

[@puffinus_puffinus5685]

Is this the same system as on your smaller boats, and what sort of scrubbers are you using? Sorry for all the questions, but i'm becoming rather interested!

[@Wrackzeichner]

Keep asking! It's always fun to answer to someone, who knows, what he's talking about. :-) The smaller boats like Eurosub and NordicSub use the same principle of CO2 scrubbers with axial fans. The fans of Euronaut are originally designed for use in PCs and servers. No idea about other ones. The main scrubber of the Sgt. peppers submersible and Control Center scrubbers of Euronaut are originally from the German FGT-I military SCR Rebreathers. Some with additional fan, some without. Got to ask for further details.

[@Wrackzeichner]

The NordicSub and EuroSub, anyway, use their own scrubber design with same axial fans, but with an acryllic housing and are made by our dutch crew member, who builds them for sale. One of those scrubbers is used in the current Triton 3300MD/1 single-person submersible from USA.

[@puffinus_puffinus5685]

Thanks a lot!

[@wksjunior95]

I loved the idea and the machine, congratulations to the whole team. But I'm curious, is It possible to pressurize the sub's main compartment turning the whole vessel in a decompresion chamber?

[@Wrackzeichner]

+Waggoner Kranmer, jes, it's possible, but where are the benefits. Making such a large compartment wit all the electric equipment oxygen clean is a pain in the ass of the lifetime.

[@wksjunior95]

+Deep Blue Sea I was worried with the possibility of the increase of pressure, damage lcd screens (have fluorescent lamps), little gauge or another thing who can be sealed in a environment pressure. The reason for asking that is because I read the description of the sub telling the great autonomy!! So I was thinking... Euronaut can be a excellent habitat for aquanauts do some research or exploration. Divers will be able to live several days underwater, But with mobility, something who a normal habitat can't provide. It will work just like a trailer for underwater vacations. (Bad analogy) PS.: Thanks for answer. I really loved your work!!! Good day from Brazil!!!

[@Wrackzeichner]

+Waggoner Kranmer, This would be certainly a possibility, but advantages of being a mobile habitat would be eaten with the problems of making the whole compartment hyperbaric. This is not only about making internal equipment pressure-proof. It is about to get it Oxygen-clean. Otherwise every drop of oil or fat somewhere inside could lead to spontaneous self-ignition. This is much easier to control in a pressure chamber, but impossible in a fully-functional submarine. Other problem. if the whole sub were hyperbaric, the whole crew is an object to decompression, when the mission is over and it would take days, just like in case of saturation divers. Noone can just open the hatch and go out in case of emergency, no outlook on the bridge, not even someone to throw a rope on the peer, when back in port. :-)

[@luke5196]

can you close that diving hatch, and what is the weight for (as I was typing the hatch was closed) Beautiful video

[@Wrackzeichner]

Luke Furtek, the weight is a back-up anchor. It allows to move the bow of the submarine up and down to give enough space for the divers to quit.

[@luke5196]

[@GJones462-2W1]

How often does the exterior of the sub need to be cleaned of all the usual clinging sea life? Annually, sooner than that, or a much longer time?

[@Wrackzeichner]

For enviromental reasons the boat didn't receive an antifouling. Scratching the barnacles was necessary every couple of months. Currently she gets a new paint job, but no idea which one is it going to be.

[@Dilidjent]

How water didn't come in at 2:30 and do you use GoPro?

[@Wrackzeichner]

+Dilidjent, the pressure in the chamber is equalized with the ambient pressure in the water. Therefore the water level doesn't rise, when one opens the hatch. The camera was a cheap chinese GoPro clone.

[@engineer0239]

does the sub feature drop weights in case of an emergency?

@@Wrackzeichner let me ask you this: she does navigate while submerged, yes?

[@Wrackzeichner]

She has a gyrocompass for true heading, when underwater, but no dead reconing and no own speed /drift measurement. So we don't really navigating, when submerged. But it's not really a problem because she is not going long distances submerged like military subs do. We are speaking about maximum couple hundreds meters around the wreck site maybe. The rest of the time she is either surfaced cruising to the wreck site or bottomed near the wreck.

[@EldeNova]

You can do this at home. Fill a sink/bucket/bath with water, take a drinking glass/cup and put it upside down in the water. make sure it's upside down before you put it in the water though! Don't tip it in. Same thing happening in the video. Put a dry sponge at the bottom of the glass and try it, it will come back out dry!

[@titisaknirattisai4843]

I think he are just a kid who's don't study science and now he grow up with no common knowledge

[@BMXNEWSCHANNEL]

It's all about buoyancy. Air is lighter than water. Air will never travel down through water & water will never climb over air. It's weird to grasp but the hole in the bottom while submerged in water creates a sealed pocket that air can not escape. Since air is trapped inside the submarine there is no way for water to take up that same area. If you tilted the submarine 90deg the air trapped will then be able to escape out of the hole giving room for water replace the space.. If that ever happened, the equalizing force of water replacing the area of air will create a massive suction. This is why people warn you about your car doors being too hard to open if you crashed and started submerging in water.. The whole idea behind needing a window pick in the event of submerging your car. Sorry I went on a rant.. My apologies.

[@Scitch87]

You forgot to mention, that there can still come water into the hole in the bottom of a submarine if the pressure of the water is higher than the air pressure. The deeper you dive, the higher the air pressure inside the submarine chamber needs to be to keep the water out.

Yes, Nautilus is a bit longer, but she has 20 tonnes less displacement (gross or net tonnage is used for cargo or other commercial ships). Still it is a thing of definition. In most cases displacement is the more important parameter.

Astronaut Gordon Cooper documented a bunch of shipwrecks that I'd love to go explore!

[@pieterveenders9793]

What I wonder about is how they prevent the dive chamber from filling up with water once they open the bottom hatch that gives them acces to the water outside of the sub. I assume the air pressure inside the sub is at 1 bar, and depending on the depth the sub is at the water pressure is several bar, so wouldn't the water rush in and completely flood the dive chamber unless the pressure inside is increased above 1 bar to match the water pressure outside?

[@Wrackzeichner]

The diving chamber is a separate compartment with the internal pressure adjusted to the ambient while the hatch is open. The rest of the sub has 1 bar internal pressure. Both compartments are separated by a pressure-proof bulkhead.

Sadly the project leader ended up luring a young Swedish journalist into the sub, and while at sea he raped and murdered her. The Danish autorities arrested and prosecuted him, for which he's now rightfully serving a life sentence, but sadly if I'm not mistaken the sub was seized as evidence in the case and eventually scrapped by the government :-(
