Vessel with submersible hulls

Abstract

New design of vessel with submersible hulls which can transport large cargos at high speed sailing above the waves and which is made up of two parallel submerged bodies (4), clearly cylindrical in cross-section or as hydrodynamic as possible, joined by hydrodynamic profiles (5). Four hydrodynamic legs (3) are located in the confluence between the cylinders (4) and the profiles (5) capable of supporting a platform or loading zone (2) which can move (up or down) on the legs (3) which have a system of vertical displacement so as to raise itself above the level of the waves. The parallel bodies of submerged displacement (4) joined to the hydro-dynamic profiles (5) can be completely covered with a textile of permeable sheets of porosity less than the size of a molecule of water and greater than that of a molecule of air and air can be pumped into the interior. The air molecules escape via the pores breaking the outer layer and separating the water molecules from the submerged area so as to reduce viscous friction to a significant degree. The lower works can be raised to the level of the sea to load and material in their interior or to enter shallow water ports.

1 . New design of vessel with submersible hulls which sails at high speed transporting heavy cargo characterised by the fact that both lower works and upper works are displaced vertically in such a way that the lower works can move between the level of the sea and a height above the level of the waves, this avoiding friction and the creation of waves and the upper works are submerged beneath the water in normal sailing and working conditions and are raised to the surface of the sea in shallow waters or for loading and unloading operations. 
     
     
         2 . New design of vessel with submersible hulls as in  claim 1  characterised by the fact that the lower works include two parallel bodies of submerged displacement ( 4 ) joined by hydro-dynamic profiles ( 5 ) and supported by legs ( 3 ) which in their submerged area are made up of telescopic cylinders which expand or retract as desired and which submerge or raise the lower works. 
     
     
         3 . New design of vessel with submersible hulls as in  claim 2  characterised by the fact that the cylinders are joined to tangential plates external to the cylinders to support the pistons on the sea bed. 
     
     
         4 . New design of vessel with submersible hulls as in  claim 1  characterised by the fact that the system of vertical displacement is of rack and pinion type. 
     
     
         5 . New design of vessel with submersible hulls as in  claim 2  characterised by the fact that the parallel bodies of submerged displacement ( 4 ) joined to the hydro-dynamic profiles ( 5 ) are completely covered with a textile of permeable sheets of porosity less than the size of a molecule of water and greater than that of a molecule of air and air is pumped into the interior which escapes via the pores breaking the outer layer and separating the water molecules from the submerged area so as to reduce viscous friction to a significant degree. 
     
     
         6 . New design of vessel with submersible hulls as in  claim 1  characterised by the fact that the engine room, motors, the bridge and the crew area are located above the upper works ( 2 ). 
     
     
         7 . New design of vessel with submersible hulls as in  claim 2  characterised by the fact that the two parallel bodies of submerged displacement ( 4 ) serve as a deposit for bulk cargos. 
     
     
         8 . New design of vessel with submersible hulls as in  claim 1  characterised by the fact that propulsion is reverse tractor type and has elevators ( 6 ).
