| what happens to old oil rigs and ships |
• Ships and Oil Rigs have a defined service life .
• When this service life is over it is really over
• There is no second life as something else ( for example as a housing solution for seasteaders)
• The structure is gone due to Fatique Cracking and Plate Thinning
• The service life of steel structures is “surprisingly short”
• ABS demands a “Mayor inspection and repair of fatique cracks” at only 15 years
• When the point comes where it is more expensive to run these repairs than to build a new ship the ship goes to the scrapyard…
• A structue that for some reason “falls out of this constant maintenance and repair cycle” becomes unsafe and dangerous very quickly - within a few months.
contex:
This old ship or oil rig is offered for sale at a really low price - can we use it for seasteading ? -
…nope…
| ship for free what it means…
It means it is at the end of its service life , is full of fatigue cracks, and the plating has become unsafe due to corrosion.
It has fallen trough the ABS inspection so it can go nowhere and it can not stay where it is right now either.
A major leak and oil spill from the slurry still remaining in the tanks is expected by the port authority within a few months as the ship continues to deteriorate quickly.
It has become a expensive liability for the owner who is in obligation to find a place to cut it down from top to bottom and turn it into scrap metal while applying to ambiental norms. This includes cleaning out the last drop of oil from the tanks and get it to a refinery where it can be injected into the fuel production process. The manhour cost of doing so is signifficant. (actually it is horrible)
The owner is therefore looking for an enthusiastic seasteader who takes the ship and releases him from the liability.
Giving it for free makes it kind of obvious that there is something fishy in that business - so most owners go for a “smarter booby trap” by charging a ridiculous small sum for the deal to make the trap less obvious.
if old ships could be used for housing that would be widley implemented by now…
jules verne had the idea already
context:
The hull of a ship has a plating that is thinner than a beer can in propotion - this is not a base for a “solid real estate development project”
A solid real estate development project needs solid ground to build on
context:
• Venice sinking after 1500 years of prosperity (technology cedar piles in the swamp as foundation)
• The World Dubai sinking (technology sand dredging vulverable to erosion)
• Today better, far longer lasting technology is on the table
Although there have been many marine powers in human history, (Minoic, Phoenizian, Chinese, Polinesian, Arabs, Vikings, Venice, Spain, Portugal, England) none of them developed floating cities to create oceanic trade hubs, and control marine traffic.
This seems not logic in the first thought but it becomes clear when we remember that the only availble building material for floating structures in those times was wood - a fast victim to the Teredo worm (within 16 weeks) and biofouling that made permanent floating structures a dream impossible to achive. Even with this ridicoulusly short lifespan of somtimes just 16 weeks at sea marine empires where built on the value and power of wooden ships.
Steelbuilding of floating structures introduced by Isambard Brunel in 1845 made floating structures a bit longer lasting - steel ships can have a maintenance free service life of some 5 years (Prelude LNG floating industrial plant) and a total service life of some 15-30 years (includes plating renewal ) until they are “structurally gone” to the point of scrap.
But this is still a “poor service life” for a floating real estate development. Real estate development requires a service life of hundereds of years (similar to land buildings).
Modern concrete floating structures can deliver the necessary service lifespan to make oceanic real estate development feasible.

seasteading, floating real estate, bottleneck, wood hulls, steel hulls, concrete hulls, permanent dwellings at sea feasible, first time in history, marine powers, never got beyond short lifespan ships, our generation can do this, our generation can do better, get a permanent foothold in ocean colonization, go beyond transport, the potential of identifying a key bottleneck in technology development and open it … investors are the key element, not politics, evolutionary approach, develop it slow, singularity approach kick it off, investor proposal list
A new development can only happen on base of new technology - todays new technology (not available to historic marine powers) is on the table - concrete honeycomb shell building the ONLY technology allowing for “permanent dwellings at sea”.
