Seabreaks for dampening colossal ocean waves?

admin · Guru

I agree completly - if people ask me how a "seastead" will look like i would say that whatever the owner wants it to look. Current commercial models are known as yachts, houseboats, but unconvential models like totora islands in lake titicaca and richi sowas bottle island also can be seen as early seastead models. No need to come up with a "fit for all concept".

I agree with you that if you take out the wave hazard in a sea area by enclosing it in a floating breakwater you enable basicly anything that floats for seasteading.

But still building a floating breakwater of "village size" is a enormous building volume... two pieces like the monaco breakwater hinged together in triangular form, pointing the tip against the waves like a ship bow would do the job ... but still not easy to achieve - one piece is 160.000 tons of building volume....

This floating piece actually protects the harbor of Monaco (which has the size of a village) from ocean waves ... it contains a parkhouse and a shopping mall. And it offers along side docking for 4 cruiseships (two on the outer side, two on the inner side.)

The key question is how small can a breakwater be to be still effective and the general answer is not below hundred meters... because it would just start to move with the waves instead of breaking them...

Fantastic photos, thank you for posting those.

To continue with my main thought, I think the focus on the size/shape of the living areas is not the proper way forward. The outer sea break is the way forward.

My personal study of free-markets has convinced me that when people are allowed to own property and are able to invest in free-markets then companies come up with amazingly creative and diverse ideas. This free-market innovation is something you can basically predict occuring, although you can't tell what it will look like.

If a sea break were constructed which (1) could repel 100' wave and (2) enclosed an area the size of a small village, then I would anticipate that free-market innovation would advance very quickly. The interior surface area of the sea break circle would be filled by an amazing assortment of habitable units.

Do they need to look the same? No, of course not. Some inhabitants will want a modest sized dwelling, and some will want a floating palace. Some will want a concrete structure, some will prefer aluminum. Etc. It's not up to us to figure out what to build, let inhabitants create and hire companies to do this thinking and building for us.

In short, there isn't a real need to determine what is the 'best' living platform for living on the ocean--the free-market will do that for us. All that is needed is create an area and invite individuals from around the world to populate it.

nice concept - i would see it in the concept of a plate seastead or a stadion seastead

If making it a bit mor elongated it could even move like a big ship...

. .

I have actually done some model testing to set the bases for a family version of a plate seastead built in concrete shell...

it could be something like this one - see a video of this here

Hi admin,

'Artifiical lagoon' led me to search Google for more examples in addition to the one you mentioned.

While I was searching, I found this article for a floating city which looks gorgeous. Have you seen this?:

Hello Pie,

Welcome and thanks for starting this thread...

In fact exactly this is what the devolpers of Palm Dubai had in mind - a artificial lagoon. The underlaying problem with a floating breakwater is that it should dampen all ocean waves. As ocean waves can have wavelenght of more than 100m and you need a structure that is several times wavelenght size to get the desired complete calm lagoon even a small version of a breakwater lagoon needs hundred(s) of meter of structure.

So that is no small scale project. Basicly to get the wave breaking effect of a reef you need to build a reef - and that is a major building volume. The Monaco breakwater has done this successfully.

Another example is the breakwater of the ekofisk oil storage tank.

If you have seen the film waterworld you remember probably the lagoon set - this was actually a floating ring lagoon that was set up in 6 segments in Hawaii .

Some other designs for floating breakwater lagoon solutions...

No, not an underwater break. I mean a surface break, that can protect the interior from large waves.

pie-in-the-sky, are u talking about a barrier underwater to allow the building of a subsurface home?--an underwater breakwater would not be needed below the surface...sorry if i misunderstood-just read this one post from this particular subject...

I imagine that if wave breaks are built in a large circle on the ocean surface, then the interior concrete structures don't need to be so robust. This could save a lot of money, and create a more tranquil place to live.

a seawall, which allows inhabitants to build in safety:

I think if the seabreak was built, then quite a few sea steaders (and yachters) would come out of the woodwork to inhabit it. Similar to 'if you build it, they will come'. People would purchase their own seasteading dwelling and ship it to the location, I think. In short, a seasteading community can be jump started by a seasteading developer by making a safe and secure seabreak somewhere out in the ocean.

Are there any designs for deep sea seabreaks on this site?
