People have an extended historical past of dwelling on water. Our water properties span the fishing villages in Southeast Asia, Peru and Bolivia to fashionable floating properties in Vancouver and Amsterdam. As our cities grapple with overcrowding and undesirable dwelling conditions, the ocean stays a possible frontier for classy water-based communities.
The United Nations has expressed assist for additional analysis into floating cities in response to rising sea ranges and to deal with local weather refugees. A speculative proposal, Oceanix Metropolis, was unveiled in April on the first Spherical Desk on Sustainable Floating Cities at U.N. headquarters in New York.
Whereas this newest proposal has gained U.N. consideration, it’s an outdated thought now we have repeatedly returned to over the previous 70 years with little success. In truth, the Oceanix Metropolis proposal has not reached the identical stage of technical sophistication as earlier fashions.
A short historical past of floating cities
The structure neighborhood was fascinated with marine utopias between the 1950s and ’70s. The technological optimism of this era led architects to think about whether or not we might construct settlements in inhospitable locations just like the polar areas, the deserts and on the ocean.
Within the West, Buckminster Fuller proposed Triton Metropolis, which might be related to the mainland through bridges. Archigram, a neofuturistic architectural group, proposed underwater sea farms.
These proposals had been directed at fixing the approaching city crises of overpopulation and pressures on land-based sources. Many had been even subtle sufficient to be patented.
The arc of this international architectural dialogue was captured through the first U.N. Habitat convention (“Habitat I”) in Vancouver in 1976. In some ways, the U.N. has returned to the Vancouver Declaration from Habitat I to “[adopt] daring, significant and efficient human settlement insurance policies and spatial planning methods” and to deal with “human settlements as an instrument and object of improvement.”
We’re seeing a pivoting that started in 2008 with Vincent Callebaut’s “Lilypad” — a “floating ecopolis for ecological refugees.”
The place floating cities had been as soon as dismissed as too far-fetched, the idea has been repackaged and is re-emerging into public consciousness. This time in a extra politically viable state — as a way of addressing the local weather emergency.
The expertise and forms of floating metropolis buildings
No floating settlements have been created on the excessive seas. Present offshore engineering is worried with how cities can find infrastructure, similar to airports, nuclear energy stations, bridges, oil storage amenities and stadiums, in shallow coastal environments reasonably than in deep worldwide waters.
Two important forms of very massive floating buildings (VLFS) expertise can be utilized to hold the load of a floating settlement.
The primary, pontoon buildings, are flat slabs appropriate for floating in sheltered waters near shore.
The second, semi-submersible buildings (similar to oil rigs), comprise platforms which can be elevated on columns off the water floor. These will be situated in deep waters. Probably, oil rigs could possibly be repurposed for such floating cities in worldwide waters.
Oceanix Metropolis relies on the pontoon construction. This is able to limit it to shallower waters with breakwaters to restrict the impacts of waves. This form of construction might function an extension of a coastal metropolis, as a life raft for island communities inundated by rising waters, or to offer cell important companies to residents of flood-prone slums.
Sovereign floating cities and micronations
Whereas some early marine utopian proposals had been responses to rising city points, many proposals conceptualized “seaborne leisure colonies.” These communities could be unbiased city-states permitting inhabitants to bypass tax legal guidelines or restrictions on medical analysis in their very own nations.
This form of floating metropolis was conceived of as a micronation with sovereignty and skill to offer citizenship to its occupants. The instance was set by the Principality of Sealand, off the coast of Britain.

None of those proposals has succeeded. Even fashionable makes an attempt such because the Freedom Ship and the Seasteading Institute’s plans for an autonomous floating settlement underneath French Polynesian jurisdiction have stalled. A current try at making a sovereign micronation (seastead) off Thailand led to its proponents changing into fugitives, doubtlessly going through the demise penalty.
A viable venture?
Expertise shouldn’t be a barrier to floating cities in worldwide waters. Advances in expertise allow us to create buildings for habitation in deep sea waters. These schemes have by no means actually taken off due to political and business limitations.
Whereas this time spherical proponents are packaging floating cities in a extra politically viable idea as a life raft for local weather refugees, business limitations stay. Other than the U.N., few organizations have the financial and political affect or motive to ship a satellite tv for pc floating metropolis within the ocean.
Given the numerous danger of a neighborhood in excessive isolation in worldwide waters, the answer to bringing individuals collectively in mid-ocean requires us to consider what connects us.
For my part, the way forward for ocean cities is in expertise campuses and in tourism. Given the numerous danger of a neighborhood in excessive isolation in worldwide waters, the answer to bringing individuals collectively in mid-ocean requires us to consider what connects us: expertise; work; and play. In these three components we see, maybe, the 2 lowest-hanging fruits (or essentially the most buoyant of potentialities) for ocean cities.
The primary is in floating tech campuses the place massive expertise firms arrange floating knowledge facilities and campuses in worldwide waters. Located outdoors nationwide jurisdictions, these campuses might circumvent more and more onerous privateness regimes or supply progressive technological companies with out having to barter regulatory limitations.
The second prospect is a return to the seaborne leisure colonies of the previous. Firms similar to Disney might broaden on their cruise choices to construct floating theme parks. These resorts could possibly be sited in worldwide waters or hosted by coastal cities.
Given our fascination with dwelling on water, even when Oceanix Metropolis doesn’t suceed, it received’t be lengthy earlier than we see one other floating metropolis proposal. And if we get the combo of social, political and business drivers proper, we would simply discover ourselves dwelling on one.
