    <p>Establishing a ramform floating base in the high seas, concrete honeycomb structures.</p><p>The ramform is a new ship design, that implements a traditional ship bow and a extremly wide stern section, to a ship of “triangular shape”. It has been implemented for a series of oceanic research ships, and for a new yacht design, called “The Why yacht”.</p><p>The broad stern makes the hull stable, almost like a catamaran hull. The bow can handle mayor waves just like a normal ship, while in the stern section there is a calm water access, for researchers, equipment handling, diver and dinghi access, that can be almost compared with a “moonpool” feature (central pool within the ship hull ) as it is seen on oceanic drill and investigation ships. The ramform has already been suggested as a “floating base in mid ocean” in the first world war in the form of “ice island”.</p><p>Rubber dinghies have always had a shape similar to the ramform – allowing the outboard motor to work wave protected, close to the watersurface in the stern part. As everybody knows they are extremly stable and still quite mobile at the same time. Ramform Banff, Ramform Sterling (red ships below) has taken the concept, scaled it up, and are providing a “stationary floating base in mid ocean” for the oil/gas industry already. But also maintain the capability to operate as a ship with full mobility. So the “ramform floating island” is reality as we speak.</p><p> </p><p> . wally-hermes-yachts-why-58x38-project.jpg . 4388238280_1a7fbac189_o.jpg . images?q=tbn:ANd9GcQ5saH0BoSRFCK9Rc3cNmqgOdCdAtsjt5nGO2_oYmvc8QzMOGjXrQ .</p><p>The ramform with its extreme broad stern, can be a quite fast moving hull as well – check the speedboat and the sailboat with ramform hull below…</p><p> </p><p> . . . . </p><p> </p><p>What we suggest here is to take the concept a step further….</p><p> </p><p></p><p>Khalifa port – a oceanic industrial structure…not floating yet – but could be – the cost per squaremeter for a concrete honeycomb floating structure is identical to the cost of landfill – so instead of creating a “artificial sandbank” in the ocean we could create a “artificial floating island in triangular shape”.

    <p>The easiest way, to establish a permanent presence in the high seas, would be to float out a ramform base, built to ship size in a calm bay, and then develop it further, moored on a open water location.</p><p>The basic charakteristics of a ramform base the “stern harbor” allows ongoing construction activity in the high seas in a “protected environment” as all wavebreaking and wave handling would go on on the bow section of the structure while the stern harbor would remain calm like a lagoon or a moonpool and allow ongoing construction activity similar to the construction activity you see in the Khalifa Port foto above. Part of the Port is already working, another part is still in construction.</p><p>This is something that can not be done with a ship hull or a barge. It is “modular floating island building”. But it will not require the finance muscle of multimillion dollar project as the ramform base would grow just like a land based settlement over many years – even over centuries depending on the development of the business ambient that drives the settlement.</p><p>The minimum size of the triangular starting piece could be as small as 20m and it could grow over time to a floating island of kilometers of lenght.</p><p> . <small> . <br /></small></p><p>A possible starting point for a modular ramform island could look like this. Once the platform has a size that all works can be developed on the platform itself the building site becomes more and more land independent. When the bow structure grows to a size and structural toughness to deal with ocean waves the ramform island can float out and be moored in a more exposed oceanic environment as the calm waterspace needed for ongoing construction would be created by the structure itself in the protected stern area. While the “wave breaking” would go on in the bow area.</p><p>The more the triangular structure grows – the bigger becomes the “protected stern lagoon” – inviting more and more business in form of tourism boats, yacht services, etc to the floating island.</p><p> . . </p><p>Finally you would come to something that is a “floating island” with a “marina development” in the stern section something like the “artist version” of a shipstead cruiseship in the picture above, or the floating port portunus. Over time bigger versions of ramform floating islands would develop into “independent seabased cities” following the business model of 17 century VENICE. While the early versions would possibly stay connected to land and work as the “marine district” of a land based city – just like the floating tourism center and floating load terminal below.</p><p> . .</p><p> </p><p> </p><p> </p><p><br /><small> . . <br />.</small></p><p>starting with a floating baseplate – then growing in land connection mode to ship size – finally reaching city or atolon size….<br />the technology for doing it is widely tested and we know that that kind of floating concrete honeycomb structures can have a service life of at least 200 years – compared to a ship in naval steel building that has a service life (with a intense maintainence shedule) of 25 years maximum – only concrete shell and honeycomb technology can give a service life with “oceanic real estate” – quality.<br /></p><p></p><p>Nkossa Barge</p><p> </p>

    Dear ellmer;

    Thank you for posting all that, and thank you for explaining all that.
    It appears to me a good idea to build modular concrete honeycomb floating structures
    with the ramform shape and with the stern harbor.

    I would be interested about your opinion on an idea of mine:

    I lived in Las Vegas when the Stratosphere Tower was built. I saw some of the building operation.
    The tower was built slowly by advancing the scaffolds higher and higher as the concrete cured after
    each pouring.

    Would it be possible to built a tower that goes downward into the water?
    Each time a there is a new level, the structure could be lowered deeper into the water. The new levels can be
    placed on the structure like four dimensional printing.
    This would be a floating concrete tube or pipe like structure. The ‘pipe’ would float vertically.

    #22570

    spark, sure the same technique that is used for forming the tubular corestructure of a highrise building can be used on the water to build a tubular structure in floating status. This has been performed on large scale on the Rion-Antirion bridge pylons, so i would consider it “of the shelve concrete building technology”.

    See a video here:
    http://concretesubmarine.activeboard.com/t45825534/the-making-of-the-rion-antirion-bridge-pylon-video/

    and more info here:
    http://concretesubmarine.activeboard.com/t45732191/rion-antiron-bridge/

    A variation of this is the building of the legs of Troll A which was performed on a floating building site (condeep) rising the whole tube up – and ballasting the structure down later.

    http://concretesubmarine.activeboard.com/t45733486/troll-a-a-concrete-floating-structure-in-the-north-sea/

    The legs of Troll A have 24m diameter and 1m wall thickness – the platform is at sea in “seasteading mode” since the seventies.

    The method you describe with the advancing scaffolds is called “slipforming”.

    Another topic you might want to might want to research in vertical floating tubular seasteads is Sea Orbiter.

    Hi ellmer;

    The video is great. Yes, I guess this is not only impossible, but it is also done already. -)
    To me this will take some time to comprehend.

    I also like the idea of the honeycomb modular structure. How would the honeycomb units be connected
    and secured to each other?

    Thank you for your answers. There might be others too who like these.

    #22577

    Hello Spark, all the techniques used in land based concrete engineering to connect elements are also valid for a Seastead. Common techniques are cast joints, post tension methods, grouting, – in a nutshell you would do ecactly the same as in a highrise building let stick out the rebar and then cast another floor on it – once the concrete is cured the floors are connected – there are no “special connectors”. The whole building will move in the wind as a unit – some highrise buildings move several meters in the upper floors when the wind is strong. The cycle load that wind forces bring into a highrise building are in the same order as wave load bring into a seastead. (A million load cycles per year).

    condeep structure

    If you check those building sites you will see that the building site does not look any different to the building site of a land based construction. This is because there is nothing different going on – it is just “off the shelve concrete building” performed on the water in floating status.

    Spark, in a seastead you also can opt for “sparse connection” imagine that like a train. You have the wagons connected but with certain movement – a good example how to execute that in big scale on the water is the Monaco floating Breakwater and the “Rotula” that connects it to land. The floating breakwater is so big that it can dock 4 cruiseships and it holds a shopping mall and a parkhouse. It was built in spain and shipped over the open sea to Monaco. So it basicly contains all elements that apply to a seastead.

    ————–

    Monaco Breakwater: a 160.000 ton seastead in use as we speak – two of those elements connected in a triangular ramform seastead would create “monaco harbor” in the stern section, with all the options and business opportunities of Monaco – without the kingdom of monaco and its “real estate on a desolated rock – really necessary. – it could be a oceanic development … this is seasteading in the making…just think it a logicical step further…

    Hi ellmer;

    It looks good. I recognize that you are showing real life practical solutions.

    I like some parts of the DeltaSync report. What do you think their next move is?

    The Bay of Fonseca could be a good choice. The Bay of Fonseca is on the Pacific side
    of the American continent. I would be more interested about an Atlantic seastead.
    From an Atlantic seasted it would be easier to sail to Europe.

    I would like to ask more questions. I will post separate shorter questions too.

    #22586

    Hello Spark, the Bay of Fonseca… i don’t know how this came up. Looks like a good forgotten part (pacific lowlands of Honduras) of a quite forgotten country, basicly a mangrove swamp, with San Lorenzo and Choluteca as “driving settlements” that would work as “host city” for a seastead. We should keep in mind that the spanish empire developed from the Atlantic Coast – so everything that matters in central and South America happens on the Atlantic/Caribbean. The Pacific side is the “forgotten jungle and mangrove part behind the Andes…” – i am quite active in marine business development in Cartagena which is the centerpiece of the spanish overseas empire – i can well imagine how business development in the “pacific lowlands of honduras” would work (don’t sign me up for that).

    spanish overseas empire

    Check the most important pice of industrial infrastructure at choluteca connecting the city center…

    choluteca bridge

    So it may make sense from a computer checking google maps in the Netherlands or in Silicon Vally … but not really if you scout the area for economic opportunities that can drive a floating city…

    Check spanish overseas empire
    http://concretesubmarine.activeboard.com/t56026816/the-spanish-oceanic-empire/

    Also compare a developed City like Cartagena that could well act as a host City of a Baystead…
    With economic opportuities in industry, tourism, trade, and all kind of marine developments.
    cartagena

    What is definitly a plus for Fonseca Bay is that a Seastead could anchor in front of 3 different countries without having to leave the bay and go for the open ocean to relocate. So this in theory gives a Seastead “negociation power”.

    There is also a plus in the fact that the seasteads economic activity would very soon “outpower” the economic activity of the land settlements – so on a long run Fonseca could be a really good option for a city sized seastead to float in and “reinvent and dominate” the whole bay and its economy.

    The problem would be the start up when the seastead needs to source from land.

    Hello Elmer;

    Now I know a bit more about the Pacific side of the South-American continent.
    The Bay of Fonseca was mentioned in the DeltaSync analysis.

    I live in Southern California. I am planning to relocate to possibly Florida, or South Carolina.

    Kind of a strange thing happened in my life. I came to live in the USA 30 years ago.
    I am originally from Hungary. I left Hungary during turbulent political times.
    There were some hard feelings between me and some communist political leaders.
    That made it difficult for me to think about a return to Hungary.
    I am a low profile person.
    During my 30 years in the USA I got to be an average East-European immigrant.

    Times changed, and the Soviet Army went home. Hungary joined the NATO, and the EU.
    After 28 years in the USA, I went to visit my family in Europe.
    My family came to visit me, in my home, in the USA.

    It is nice and good to this point. Most of my family members are allowed to enter the USA
    with and ESTA visa weaver for 90 days. So my family members came to visit me, and stayed
    for a while, and before the 90 days would be over, they left and went back to the EU.

    Right now I have a US citizen passport. I can do the same 90 days in the EU.
    Under these immigration laws there are not much chance for me to be with my family for extended
    period of time.

    I learned to sail. I think I need a bigger sailboat.
    With a sailboat, seasteading seems to be a logical choice. With the EU connection the Atlantic
    side is more logical. A seastead can be placed outside of visa requirements.

    The reason I wrote this down here, is, that there may be others with the same difficulties of visa
    requirements. I think seasteading can be a solution for me.

    Hello Spark, Yes i read the Delta Sync report, i am familiar with the whole dutch floating housing network, and the designers and engineers around the university of Delft are also part of my network.

    I find it interesting that your origin is in Hungary – i was born in Austria so we both share a experience to have seen first hand how quickly political inmoval sistems can collaps within a few weeks.

    We probably also share the experience that “personal mobility” – can be a factor of freedom and how states, legal sistems and travel restrictions tend to tear families apart. I suppose that this brought us to boating, yachting and oceanic freedom as “ultimate freedom resource on the planet” where overpopulation and third party interference is becomming more and more severe. My postulation (and part realization) of the Captain Nemo Float Out is a outcome of that kind of experiences.
