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.
World economic and political center is shifting to Pacific. Seasteads in Pacific seem like a wise decision. It has more perspective, in my opinion. Spanish Empire is in the past, frontier has moved.January 7, 2014 at 1:26 am #22615
We do have a lot in common. Austria was nice, when I was there. I think Austria is still nice.
I think, Oceanic is the way to go. I am willing to bet on that.
Nice to hear from you. I like the pictures and the blog. The concrete submarine is amazing.
My blog is not so spectacular, but here is a link to anyways:

Ancient, exctly this is the point to make a fully mobile seastead type shipstead – to have mobility when a position shift for economic, political, or whatever reason is indicated. The ramform allows to deal with big waves over the bow. It is the smartest way to get a relative small floating island seaworthy. The minimum size (for open sea comfort) is along the lines of Ramform Banff, smaller sizes like Kon Tiki can make it over wide extensions of ocean – but survival in Draupner events is doubthful. Anything that is smaller than Ramform Banff should drop the “surface floating platform” concept and go for a “wave overwash capable bubble” concept instead.
Ramform Banff oceanic floating base.
A merger between ramform and bubble concept could look something like this:
As Jules Verne predicted mobility is a quality that opens a window to many things – Captain Nemo’s motto was Mobilis in Mobili … so i think seasteads – especially smaller ones that have not reached city size yet should keep mobility as far as possible.
The key technology to get something like that on the water is concrete shell and honeycomb building. Naval steel and yacht resin methods are ruled out by the cost factor.
This technique produces living space on land successfully – it is also suitable for ocean colonization. The point is if housing is the purpose it can not even remotly be based on oil platform or ship technology (cost factor out of orbit), it must be a development that projects land based housing (with its established squaremeter cost) to the oceanic environment. Concrete shell and honeycomb structures can do that – and still be mobile like a ship.
The heart of ocean colonization is to develop the core technolgies of the new frontier, this is where the money and the business is.Investors should consider to get a foothold in ocean colonization infrastructure development :

Ramform Banff to Remain in North Sea After Upgrade to Reduce Roll
05 Sep 2000
HOUSTON & OSLO, Norway–(BUSINESS WIRE)–Sept. 5, 2000–Petroleum Geo-Services ASA (NYSE:PGO)(OSE:PGS) announced today that after several weeks of discussions with the U.K. Health and Safety Executive (“HSE”) and the Banff oil field partners, the Company has now received approval from both parties to proceed with a vessel improvement plan which will significantly reduce the roll motions of the “Ramform Banff” Floating Production Storage and Offloading Vessel and allow it to continue operations in the North Sea for the foreseeable future.
The planned modifications will reduce the vessel roll motion, both in storm and in more moderate sea states, by around 50%, improving the vessel’s production and availability record. This upgrade, which is expected to cost less than $20 million, will require a short shipyard stay in the fourth quarter of 2000. The “Ramform Banff” is expected to be back in operation before year-end.
“This vessel modification will bring the motion characteristics of the ‘Ramform Banff’ to the original design specifications and exceed all the necessary safety standards, which is our first priority,” said Reidar Michaelsen, PGS’ chairman and chief executive officer. “While the brief shipyard stay will have a slight negative impact on near term earnings, this is largely offset by a marginally improved earnings potential elsewhere in our production services business for the remainder of 2000. More importantly, this upgrade will protect the long-term value and earnings potential of this asset.”January 10, 2014 at 9:46 am #22621
However in practice, Atack says, “it took us a long while to determine that the roll motion of the Ramform was too much in heavy seas. The media were very keen on reports that it was making our crew seasick, but that was really not the problem. Once the vessel moved beyond a certain range – 7.5 degrees of roll – operations had to be closed down. In fact, there were not many days when 7.5 degrees roll was exceeded.
“However, we determined that the behavior of the vessel still didn’t fit our expectations. This was unacceptable, in considering the effects of severe weather on the structural integrity of the vessel’s equipment. This called into question the original model testing, so we conducted more model tests, which proved that the roll motion wasn’t good enough.
“We performed three series of model tank tests and found that through the simple addition of bilge keels, we could suppress roll by 40% – a huge degree of damping. This would apply not only to extreme weather, which occurs less than 1% of the time in our location, but would also calm the vessel in a regular seastate.
New bilge keels
“It looked simple on the model – but in practice, we were talking about fitting 1.4-meter wide bilge keels along about half the 120-meter-long FPSO. So this would clearly be a significant construction project. We did look at doing the work at sea, to avoid a shutdown, but this would have required a sustained period of calm weather. Then we would have to have put the keels on in sections, so it would never have been as good a job as if performed in a drydock. And it would also have taken longer to complete.January 10, 2014 at 9:51 am #22622
For the floating production system, Conoco has commissioned a larger version of PGS’ Ramform concept, hitherto employed purely for seismic vessels. The new double-hulled ship, under construction at Hyundai’s Ulsan yard in South Korea, will measure 395 ft long by 175 ft wide. Other ship-shaped floaters in the North Sea are almost twice as long, at 700 ft.January 10, 2014 at 10:17 am #22624
The double hull design has a storage capacity of 120,000 (onboard) plus 500,000 barrels to be provided by a distant moored Floating Storage Unit (FSU) and later a shuttle tanker. The hull is 395ft long by 175ft wide. The vessel weighs around 10,000t, excluding topsides module and helideck. The load bearing capacity is 16,000t. The octagonal steel helicopter deck measures 22.2m by 22.2m and is suitable for EH101 type helicopters.January 10, 2014 at 3:56 pm #22625
Spark, I didn’t know you are from Hungary,…I am Romanian. Kinda of the same thing w/ me too, I’ve been here for 25 years. Anyway, I have some pics of a ramform floating island I designed some time ago and I would like to show it but don’t know how to insert them. Anybody?January 10, 2014 at 9:30 pm #22626
exctly this is the point to make a fully mobile seastead type shipstead – to have mobility when a position shift for economic, political, or whatever reason is indicated.
What I wanted to say is that if a seastead starts in Atlantic, then it may be too late to sail to Pacific some time in the future. Because some other seastead may form there, that gets all the business connections needed and steals all the business opportunities, and forms trustworthy relationships with the neighbors. Mobility doesn’t mean one doesn’t have to stay on the frontier anymore, it only means that it’s possible to relocate to the frontier. And right now Pacific seems more profitable in the long run, in my opinion, so for me the decision to create a seastead there seems weighed.
As Jules Verne predicted mobility is a quality that opens a window to many things
I wouldn’t say he predicted it, nomads like Mongols were exploiting mobility hundreds of years before his birth.
Worldwide the cities are running out of land based development space
What makes you say that? Megapolises occupy a tiny fraction of available land.January 10, 2014 at 11:56 pm #22627
I am glad to be in the same group with you.
I would like to see the pictures.
One good way to show them, is to put them up in an Internet storage area, like http://www.flickr.com/
and post the web address of your pictures here in the blog.January 11, 2014 at 12:07 am #22628
This honeycomb structure would be interesting.
May be new kind of building units can be developed. Like the building units for
houses can be a cinder block. May be a new kind of cinder block, unique shape and size,
could be produced on land, and a structure can be assembled in the water.January 11, 2014 at 9:00 am #22629
Ty Spark. Forgot about that option. Here they are.

The best visualizations how a ramform floating island could look like.I like the built in land connection. Foto above and the marina harbor feature in the picture below.
According to the non linear wave model (Draupner Event) it needs to be capable to take a 30m wave over the bow…Non of those is clearly a vessel, a island, a barge, or a marina development, so you could place it conveniently as ANY of those concepts in a business environment.
