Abstract: Ultra-large marine submersible transport boats and arrangements for aqueous bulk liquids transportation, including fresh water and irrigation drainage, from specifically configured supply stations to specifically configured delivery stations. Boats present rigid hydrodynamic shaped double-walled submersible hulls incorporating a plurality of inside-reinforced impervious ballast chambers and also present radial reinforcing elements and hollow interior cavities that enclose collapsible bulk liquid bladders for transporting bulk liquids. Hulls can be made of reinforced concrete. Hull openings permit seawater circulation, avoiding transportation of bulk ballast seawater. Submersible cruising reduces structural loads and drag. An on-board hydro-pneumatic ballasting system adds to and removes reusable hull ballast water from, the ballast chambers controlling the hull's depth, pitch, and roll.

Abstract: A building over the water, maneuvering methods for the building and hosting sites of the building. The buildings including a superstructure (A) provided a floor structure (1) that is placed over a water surface (2) on which an inhabitable subassembly (3) is positioned, a support (B) sitting on ground (4) positioned under the floor structures (1), and mobile floating docks (C) with variable and controllable buoyancy that includes a load carrying platform (5) positioned under the floor structure (1). The superstructure (A) is held above the water surface (2) by the supports (B), that sit on the ground (4), and respectively carried by the floating docks (C), the superstructure being detachable from the ground (4), and transportable on water on the mobile floating docks (C), thus being possible to reposition the superstructure (A) on ground (4), at a destination of choice.
