Open_Sailing_Data

Hiromi Ozaki >

For the Danube River journey after Ars Electronica we're designing a 'box' which sends information of the vessel (GPS, pressure, temperature, humidity) to Pachube so people could observe our conditions online.  Data logging is also very beneficial for our research in Nomadic_Ecosystem and Energy_Animal!

The source code of hi-ve is now made public and open on source forge.
the address is here:
http://sourceforge.net/projects/hi-ve/
its development svn can be accessed with the following commands.
svn co https://hi-ve.svn.sourceforge.net/svnroot/hi-ve hi-ve

We will put up the hi-ve executables for download very shortly.


Here are some notes of the current design direction of the 'data log box'

Open_Sailing_01 skeleton model, scale 1/3

Building and playing with this 1/3 scale model informed a couple of necessary changes :
- the floor must be thicker and "articulated" to resist the most violent waves.
- large surfaces need to be strongly triangulated, in addition to the steel mesh.
- hey, wood is such a nice material, we might use more of it.





So, yes, we are actively looking for a construction site, if possible in London to build this :
- 9.6 meters in diameter
- 4.5 meters high
- about 2 tons in total, BUT every single piece is lightweight and human maniputable : which means, we can easily move individual parts around and assemble them on a slipway, or on the shore when the tide is low.

We don't need to have such an immense space in one piece : we can build bits by bits and take parts by parts to the water.
We have currently visited 4 sites, many are almost OK, we still believe we should search more, for now all solutions we have are very complicated... If you know a large workshop, a derelict factory, a pier, a boat construction yard, a nice backyard, a big parking lot ... Whatever you have as land, we are interested, let us know : coordination@opensailing.net.

Really cool website with mad materials !

construction-details

A bit of extra information of the structure construction process.

We are going to coat the trimrans -the downside of the vassel - with insulation sprayfoam, then coat it with fiberglass to make it resistant and finally a resins coat to get ready to sail!

Open_Sailing prototype 2 Paris

Learning from the first experiment, we wanted to optimize the design of the Open_Sailing_01, this is prototype Paris nº 2.

So according to the prototype Paris nº 1 and its defects, we have changed :
- enhance capability of self-righting (more floatation on top on every side)
- reinforce overall structure with metal mesh rebar
- Addition of the flexible ballast (inspired by Givens invention)
- make the 3 hulls deeper and slightly curved to dive in the waves more smoothly.
- have 2 anchoring points for 2 kites attached to the main frame front
- have 2 lateral openings on each side for fishing and rowing (alternative emergency propulsion)
- main openings to have an doorstep higher to avoid too much water entering in at all times.

Self-righting, insubmersible boats

The design of the Open_Sailing_01 has been influenced by the Givens Inflatable liferaft.

You can download here the .pdf of the Givens US-Patent of James A. Givens 1988.



Download the pdf the self-righting boat, Patent of Derek Wright 1991



And lastly, the large inflatable life raft with a central pilar to hold the roof, pdf patent of Baughman 1989.



So this is our design, Open_Sailing_01, inspired by these inflatable liferaft technologies. We try to combine these technologies in something simple and efficient.

Open_Sailing_01 skin proposal

These are the walls on Open_Sailing_01, 20 cm thick of floatability, under pressure for rigity with ø10 steel staples.

The thickness should ensure structural fonction, no need for huge metal beams -> exo-skeleton!

This is a very cheap construction material, all materials are remaining separate which means, it is easy to recycle each component separately, or recycle the materials in the next iteration.

Imagine the inner skin to a bit like this (in white):


Hehehe! Old english! So now, it is comfortable, you want to join? He!

How to build a yurt

This is fantastic! So simple, so adaptable. Note that the interior is the first thing to be put in – the whole structure is built around people, not people having to fit round constraints of the structure. Lovely!

Cheap vs Reliable?

Peter;

Can we name a couple of demands that should apply to our ocean going vessels?

I like the idea of working with recycled materials; not only is it cheap, it also is a great way to battle pollution. So I definitely think we should try to use old PET bottles, tires and so on.

But since it's ocean going It should be reliable, too. The waves will not be 100t per square meter since the vessel will not be very heavy, but still it's going to have to be strong. If you want to take it out there were it can get so ugly, I want something that can take a beating for sure.

Is it possible to combine all the factors? I worked on earlier drawings to see if I could combine cost efficiency, product efficiency, reliability of the structure, use of recycled materials and user friendliness on open sea.


It needs to float. By using PET bottles you're using not only a very strong container, you use a lot of them. When a couple of them loose their buoyancy it will hardly have any effect. that's a good thing. Using recycled materials will keep the costs down and the environment happy.

It needs to be strong and stable. Seas get rough. Waves are beating the structure up, salt water is very aggressive, it has no shelter from the high winds. By using a cylinder shaped box for the plants it will be able to withstand the impacts of waves. Using plastic or glass fibre the box will remain light which will make it easier to keep the structure up straight and out of the water. The sand in which the plants grow will make the top heavy. For stability, a weight under the buoy will have to make sure the point of gravity stays low. I needs a lid that will increase the strength of the structure during bad weather.

It needs work efficiently. A massive construction for just three plants seems like a waste of... well, just about everything. So less is more when it comes to the use of materials. I can imagine big, flat dishes that float on pallets of PET bottles.

It needs to be user friendly. Gardening is a lot of work so you will have to be able to reach the plants as well. By surrounding every cylinder by a little ridge you can stand on, you'll be able to work in the gardens. When multiple cylinders are hooked together in a flexible way, the stability and accessibility will increase.

It needs to be plant friendly. Plants will not grow in any situation. Making them happy is actually more important then anything else. A super strong construction in which the plants all die, is no use. So the plants need to be above sea level so they will not drown, they need to be protected against high winds, high waves, burning sun, parasites etc. I see this as the biggest challenge actually.

Boat with wheels and tyres!

We love tyres ! And there is a lot of them!



BUT! Is it too pollutive? What if it covered with bio-fouling?

Recycling gas tank

The more I look at our open sailing main shelter, the more I think it would be so easy to recycle a gaz tanker...

Bernd and Hilla Becher
The industry exists, it is actually quite common, people have to renew them and they even sometimes pay to get rid of them! ... Today I (Cesar) got a ticket for Morocco to visit the main potential construction site, in Jedida... I'll be there between the 14th and 18th of march 2009, I will take many pictures and videos and make fist solid contact with local authorities, industries and people...

Tensegrity

Tensegrity is an interesting principle that we are looking at utilising for the Open Sailing boat and equipment. Put simply, it is a method of ensuring a beautiful harmony of compression and tension between elements in a structure. Unlike in normal structures, beams don't need to touch each other, but are held in place by tensile wires.



This is one of the simplest structures possible, and takes the form of a prism. Note that the beams don't touch each other, but the structure is supported nonetheless. Tensegrity structures are currently mainly used for ornamentation, but increasig research is looking at their possibility as architectural elements.
