    I would think, that the 3×3 modules could be sub-scale prototypes.
    30×30 sounds better for the real thing.

    The ‘honeycomb’ modules could be 30×30, I would think.

    I am not sure, but I try to think about these structures as three dimensional structures.
    What ever is above the water could be just the ‘tip of the iceberg’ .

    By the way, there might be more data about icebergs, how they float, and stand up to
    storms and waves.

    It is late here, and I am just writing down random thoughts.

    Hello All. I’m here because of the Seastead projects. The combination of political and ocean living caught my interest. My goal here is to use this in a short fiction story.

    Looking at a platform 160×160 feet, maybe 10 feet tall.
    honeycomb interior with 12 interior rooms (11 walls).
    The divided compartments would be square.
    The material to be reinforced concrete.
    The platform is to be used like large house boat.
    Surface structures to be 32 unit “apartment”.
    Each honeycomb wall section would be 13 foot span.

    For this span, with concrete, is a 6″ wall thickness sufficient for outer walls (sides and top)?
    Can we get any thinner for inner walls (honeycomb)?
    Can the bottom surface be thinner?
    I’m working on a rough calc for weight and displacement.

    Good luck to you with your short fiction.

    It is probably a concept error to think in Bulkheads, modules, platform sizes etc…We need to get familiar with the idea that a oceanic city will be a city after all – with all kind of “designs” and “structures” and functions coming together as a “cluster of human activity”. It is neither a “design contest” nor a quest for a “fit for all solution”.
    There is no need for a discussion “either this or that” – because the simple answer is “all of it”. No “designer” will make the decisions on what to build – the real estate buyer and finance market will. The starting point will be just there where we are now in floating structure building – applying concrete honeycomb and shell building just more of it just scaling it up.
    A good fiction novel that will be taken a “visionary prediction” in a couple of decades makes a precise investigation what is “out there already” and then does a “not very far fetched” projection where this will lead to – check the Novels of Jules Verne…Functional Submarines, underwater Salvage (Simon Lake) the Siebe dive helmet – all this was already a reality when Captain Nemo was projected as a “Sify vision”. Jules Verne was aware of that – the average public of his time was not – they considered it “phantastic”.

    Floating concrete honeycomb and shell structures in City Block size with shopping malls inside are already floating as we speak (Nkossa, Monaco, etc…) VENICE has already 1500 years of successful history of a “waterbased society” brokering power politics of surrounding land nations and dominating sea trade. Offshoring of money, assets, business headquarters and lifes to get out of jurisdiction is going on on large scale in the Megayacht Industry.

    Nothing of what the future brings will come “invented out of thin air” it will be a logical evolutionary step of what is here today already – on a oceanic waterplanet with a population growth of 1 billion per decade ocean colonization will not come as a “exotic idea of a couple of dreamers” it will come as a development need for shore cities running out of real estate space. As a quest for “interference free space” to develop business ventures.

    Agreed. That’s why I’m asking for some specifics.

    Ellmer your photos depict monolithic projects (one vision, unified construction). My fiction forsees a city that starts out with a plan, but as it comes into being, changes in management, political structure, corporate ownership and citizen input forces changes to the plan, which are reflected in various floating structure designs and design compromises. This is just how a real city grows.

    But for a given level of realism, I need to come up with an accurate “visionary prediction” of what is possible in the near future. Ellmer, I see that you have predicted somewhere online a cost of $800 per square meter for concrete floating dock, but that the Monaco Breakwater ran nearly $14,000 per square meter of surface area. That’s a big discrepancy. I’d like to come up to a probable cost, size and physical characteristics (displacement) that i can use as a base in my fiction.

    LOL, talking about levels of realism,…with a “corporate ownership and citizen input forces changes to the plan”? Corporations don’t have citizens but employees. Their “input” is work, and that’s about it, they don’t force no “change of plan”.

    You’d be better of with a bunch of idealists trying to set up an utopia on the high seas after they all won the biggest power ball jackpot ever while pitching a dollar each and, of course, not knowing what to spend their money on :)

    True, corporations don’t have citizens. But they have customers as well as employees. The employees input work and receive money. The customer input money and receive goods and/or services.
     
    While the corporate management is not required to pay any attention to what either wants, it is in their own best interest to at least listen, and to make changes where is financially and operationally practical to do so.
     
    Otherwise, if there are other better options available, they may lose their employees and/or customers.
