The Ekofisk Concrete storage Tank a model for a seastead.

 

. . .  . .

The Ekofisk Tank model gives also a good idea how you would cluster seasteads in close proximity and use gangway type connections to cross over in severe weather conditions like the north sea is presenting.

The breakwater ring of the Ekofisk Tank is an early example how you would use concrete in honeycomb structure configuration to get something that is strong, light, can take wave impacts. Instead of massive concrete walls that are expensive, heavy, and do not let pass light, a combination of truss and holes give you the freedom to design "strenght" where needed and "openess and light" where wanted.

 

The oceanic concrete sphere would be the endpoint of this development. A maxumum of space enclosed with a minimum of material in the strongest possible way. The plate seastead could  be understood as a minimalistic part segment of a sphere sparing the upper 2 thirds of the enclosure that becomes innecessary when the seastead is big enough that "no ocean wave" including the Draupner Wave can reach this upper 2 thirds of the structure.

Small versions of a seastead will need this upper 2 thirds of the enclosure in the same way as bulk freighters need the Mc Gregor hatches over the cargo holds when a "wave overwash" comes in.

In short floating platforms are ok in a protected bay where wave impact and overwash will not happen. But when you really go oceanic and Draupner impacts need to be a integrated part of the concept, concrete shells are required as building method of choice.

 

 

Big plate seasteads which have more or less the size of a football stadion will be oriented to the inside (like a football stadion is oriented to the playfield) the seaview on the high seas is boring this is why cruiseships already follow that principe.

This allows the application of a windowless outer seawall that is the principal defense of the plate against the ocean.

A wall height (freeboard) of some 15 m should be acceptable. It would be a similar concept to a container ship. Like the containership the plate seastead would NOT feature a deck to protect against flooding in the case of a wave overwash. The only defense against flooding is the (enourmous) height of the freeboard (15m). We can consider "putting a deckless plate structure on open ocean" a proved engineering concept that has been tested out already by container ships.

With a population growth of 1 billion per decade and landspace in short supply - coastal cities have no other option than "look out to the ocean" and start floating developments.

Futuristic honeycomb / plate structure / the combination of hollow honeycomb light shell and glass / acrylics surfaces allow for lightweight, daylight friendly structures that can still take the impact of  a oceanic "tail event" like the Draupner wave.

In this "artist phantasy model" the woven hollow concrete beam honeycomb truss structure shell allows for a extrem high structural strenght that outranks any ship as it is in service today. There are big window areas but those big windows are reinforced with additional truss structure from the inside so in case of a wave impact the damage is moderate and stays localized.

.  .

London flooding, a big concrete tank was ripped out of its foundations by the buoyancy forces and started a life as "floating concrete cell" involuntaryly. Floating honeycomb and shell structures take the principle and convert it to a "base technology" for floating oceanic cities.

A extreme form of the plate or stadion seastead is the depth scraper seastead - which is a kind of inverse skyscraper.

The idea is present quite a while - but why build a tubular tower structure when a shallow stadion like plate would have much more light and would be probably much more economic to build.

 

Anyhow the technology is there - 350 m deep tubular concret structures are in use as we speak (Troll A). So can be considerd "of the shelf engineering" - a variation of the depth scraper is the "Sea Orbiter".

The key question how much freeboard you need for a structure that features no deck is pretty much answered by container ships that don't feature decks either.
