Underwater City

This project is an investigation for an underwater skyscraper and an artificial island. It is the combination of a Mega Float and a Tension Leg Platform (TLP). Mega Float is a large artificial island and TLP is a buoyant platform held in place by a mooring system.

The submerged main hull of this “Underwater Wonderland” is stabilized by the platform that uses moorings in tension to keep its position.  The main body is an inverse cone with a concrete core that handles the load with radial steel beams at every 30 meters and Tuned Massed Damper to control vibration caused by lateral forces.

The structure contains a spherical observatory, a waterfront with theatres, opera house, pools, aquarium, sports complex and a scientific laboratory.
