The Japanese Technological Research Association of MegaFloat has been using its investigation of MegaFloat Technology to float 'very large structures' to deal with the potential problems of a lack of habitable land, frequent earthquakes or the need for more space for buildings. Using MegaFloat Technology, it has built an experimental runway for an airport in Yokohama bay, which has been successfully tested, for prototyping in the near future.

The main function of this mooring system is to keep the movement under the safety limit. The MegaFloat structures can resist a small amount of water activity, but, depending on the nature of the bay, caisson or cellular breakwaters may be needed. To reduce the transfer of wave shocks, a rubber plate is inserted to absorb the force and transfer it gently to the floating structure.

The MegaFloat 'rolls and pitches' due to the waves hitting it, but - as in a ship - due to its size and the fact that this is impacted by a large number of waves, is generally imperceptible: the upward thrust and downward pull cancel each other out.
