    Sure mobility, make the concrete shell blimp shape and put a small engine in it – but that would already be the “Captain nemo float out” mobilis in mobili…have been there have done that. http://concretesubmarine.activeboard.com/t43942461/the-captain-nemo-float-out-seasteading/

    Only for millionairs? Absolutly not! You can start with something small like this. You can try to get a permanent anchor permit as a bouy for this and promise to run and maintain the lights of a “reefmarker” to facilitate the coast guards work. This makes you a “desireable piece of infrastructure” instead of a piece of “undesireable development”. The picture on the right is my prototype. In your case i would not apply for vessel status applying for this status has a lot of downsides, especially when you are at very low budget and resources. There are “tons of ruling code” a vessel needs to fit in and keep your project inside that “code” is expensive and unconvenient – at least as far as i know Florida regulations study the Lozman case before you rush down the wrong “authority handling road”.

    concrete shell structures
    From what you comment here i asume that you will be surprised that floating concrete shell structures of 70m diameter have already been placed in the sea and on the seafloor and are performing there for decades without problems and decay as we speak. The ocean facilitates the construction of large concrete shells.
    All plans like “urbanize the Amazon” settle Australia ect. that have been up and moving forward vigourously in the seventies are now shut down as people notice that disturbing nature that way causes mayor trouble to the planetary ecosystem. We will need to “build existing settlements back” and give nature more room instead of “using up more apearently empty land” for human activities.
    A floating concrete shell structure like the one you see in the picture above can recieve a shipment of grocery anywhere on the ocean – Coober Pedy in the middle of Australia can`t that is oceanic mobility and the reason why almost all mayor human settlements are near coasts or rivers that facilitate transport.

    This is one of the reasons that make floating headquarters like Abramovic is using so elegant – you can not do business with the center of Australia from a Yacht but you can approach all mayor business centers on earth from sea without crossing anybodies border and ask your business partners to come on board for a meeting with a 3 minute boat ride from shore.

    The first floating business wave is ocean related business, tourism, ocean food, energy. On the long run as space on land becomes expensive and more and more interference overloaded the dynamic pushes business out of population centers seeking interference freedom, space, mobility and resouces on the oceans…http://concretesubmarine.activeboard.com/t56680633/the-reasons-why-oceanic-business-is-the-next-big-thing-to-co/
    Finally fabrication sites, residential condos, all human activity that needs space will take advantage of the space available in the planets “hydrosphere” that counts for 99% of the habitable volume available on the planet. Space on land will need to be kept as a “wildlife reserve” to avoid further mass extinctions due to human activity. It is not feasible to asign more space on land to megacities. The only space that can be made available to human activity is the 99% kept untaped so far. We see floating LNG plants, floating tourism developments, floating seafood production sites, floating energy installations, floating minery, already, this is not “utopic” it is happening and it is unevitable. It is predicted that the 21 century will see more construction activity at see than on land.

    oceanic concrete sphere tension anchor . oceanic concrete sphere growth
    To envision the oceanic concrete sphere habitat two fotos: A tendon anchor, and barnacle growth on a habitat that has been several months in the ocean. No chance for “paint protection” only concrete can stand that.

    Ocean, i don’t think that there are “versus discussions” of the kind you are talking about, fact is, that when we colonize the oceans the 99% of the planet space volume of the underwater world will be part of it and all kind of technologies will be part of it, all kind of structure sizes will be part of it.

    There is no discussion that clutter the surface of the open ocean with houseboats like Aberdeen Harbor will not happen for the reasons anybody remotly knowledgable in marine affairs can name.

    Therefore to speak of a “seasteading start up” while using houseboat technology that depends on bays and repeats Aberdeen Harbor (on minor scale) is a long shot. It is a bit “solving the problem of ocean colonization by NOT solving it” and repeat what has not solved it for 1200 years (Tanka houseboat floats).

    The reason why things like this (Khalifa port) recieve attention and finance is because they have “potential”.

    The reason why tings like this do NOT recieve attention and finance is because they have no potential.

    What differentiates VENICE from a Tanka floating village is the “fleet dominating mediterranean trade”. The business model. Not the floaties. It does not matter what the initial size is, it does not matter what the wallet or share of a backer is, the only thing that matteres is, that there is a “Ongoing Dynamics of Potential and Business”.

    Definitly you can create business dynamics when doing single family floats in a protected bay. For example tourism developments like this…

    The key is to avoid the Tanka stagnation … potential for development to other things than a floating slum is important.
    If a proposal does not get attention and finance it is important to analyze why that is so – improve the proposal and try again to get attention and finance. This is what developers do.

    Ocean, I am all over it… google up : ocean colonization key player network…houseboats just lead to this…

    see: Tanka, Moken, Uru, Floating Neutrinos, Richi Sowa,…millenia of “no transcendence to a powerfull floating city” you really need to go out of protected bays and the marginized floating communities segment. A business development plan is key – not just floating out something…

    .
    This line of designs (submerged) definitly provides wave tracking free living space in open ocean and can survive any hurricane. Other than surface floats that need size to create stability in waves, this kind of “submerged living space bubble” is just fine in “family house size”.
    .
    Can be free floating and mobile or have a tension anchor, whatever is convenient for the business model.

    On the other hand a surface floating concept would start as a small Ramform in a protected bay (brokering shore side interests) and when it reaches sufficient size to go oceanic (400m) it will no longer depend on the bay and its protection and become a true global player that can move to any spot on the liquid planet surface.

    http://concretesubmarine.activeboard.com/t51926036/establishing-a-ramform-floating-base-in-the-high-seas-concre/
    In ANY case the structure will be a floating concrete shell or honeycomb structure that has a maintenance fee service life of 200 years (probably 2000 years).
    Tubular structures can be designed for a hydrostatic load of 500m with a 1:3 safety factor, spheres can be designed of a depth of 1000m with a 1:3 safety factor. This opens the possiblility to untap 99% of the planetary volume (the oceans) for human living space and activities.

    This is the key problem for all surface floating structures if they do not reach a size where they stop tracking the waves of the open ocean (400m) there is no chance to establish a suitable living space on a surface float. The only way to place something small in the open ocean that does NOT track the waves is putting it below the surface. There is a good reason why nature in 500 million years never developed a surface floating animal or plant to colonize the empty watersurface. All animals that live in open ocean do it submerged for good reasons. So if you want to combine family house size and open ocean you need to think in submerged solutions. Family house sized surface floats are ok for protected bays – the Tanka, Uru, Moken, do it for at least 1200 years now – without transcending to something more than a “marginized floating community in protected bays”. So what is the benefit in being a “modern Tanka”. This is exactly what “live aboard yachties” do in anchor bays around the world. If it becomes big, it becomes annoying, and the city running the show moves the “floating slum” away by regulating it out of existence.
    You need to do something DIFFERENT than houseboats and boats in general or ocean colonization will not happen.
    This is especially true since Neil Sims provided us with a JOB for a family in open ocean. Drift cage aquaculture.
    http://vimeo.com/44464996
    Check especially the part where Neil Sims is talking of the oceans way to break things that float on the surface (like the yacht being tossed around while following the cages for months) and proposes to run ocean drift cage ventures submerged “like a space station”.
    The choice for open ocean is – build it really big – or build it submerged – there is no other choice for putting living space on the open ocean.

    Guys this is more or less the point where we “definitly lost it” when the topic was discussed a couple of years ago. And everyboy who has a slight idea of marine engineering went away. Remember what we are looking for is a structure that can stand maintenance free for at least 200 or better 2000 years – if we can not get there, “real estate on the ocean”, “cities on the ocean”, “societies on the ocean” will just not happen because they will not have “solid enough foundations” that give them the timeframe necessary to develop. So forget any “steelcable with spring tension and that universe of solutions” …
    We need something that is simple to build, simple to handle, lasts for ever in marine ambient… no steel components in tubes, no springs, no exotic and untested materials as structural components…
    This leaves us pretty much with concrete honeycomb and shell construction as only feasible solution…
    No “boating concept” like “break up in a storm”, “run for safe harbor in a storm” can be applied to a city. You can not handle around things that have tousands of tons of mass in storm conditions…this is a concept error.
    What we need is something that can take what ever comes up and give shelter to its inhabitants in any condition that comes up it is as simple as that.
    The structures we are looking at as “role model” are floating concrete structures with a 30 year service record and cero deterioration reported.

    I don’t have the shadow of a doubth that if you can form that bow in steel plating, you also can form a sphere. Looks like you are very crafty in steel – so using that for your “personal castle on the water” makes a LOT of sense to me.

    #23289

    We are certainly off topic on the Oceanic concretes sphere habitat thread, but do i see 12mm marine steel plating in these pictures ?!! this is a thickness considered normal for the shell of 250m merchant ship of several thousands of tons of displacement – looks like “seriously overbuilt” for a floatie like that…

    #23287

    Kat, keep an eye on the required maintenance shedule, and build the structure to enable bottom sandblasting and repainting on a regular base. Steel has advantages and disadvantages like any material you use. As long as your personal castle fits into a drydock and can be taken out of the water once a year your personal version of seasteading can well be built on a steel hull. The forming of round shapes (especially Sphere Habitats) is a bit tricky in steel plating…
