A new Generation of Hydrodynamic Mobility
One ultra-fast ship crosses the Pacific and Atlantic in a couple of days, and transports the same load as five classic slow-steaming ships.
The Marine Wheel-Revolution is the scientific turning point of more productive shipping in 95 % of global transportation that break speed limits once for all and sends the industry into a new Age of Innovation.
Cavitator-Stabilized Supercavitating SWATH
InSvivia Technologies’ patented cavitator body makes a gyroscopic- and radial-interaction-stabilized supercavitating SWATH for maximized gas isolation and minimized waterplane area.
The drag-escaping hull surfaces reduce the fuel consumption to a fraction of conventionally possible, and send large ships up to supercavitating speeds of 80 knots.
WHAT IS A SWATH?
A SWATH (Small Waterplane Area Twin Hull), minimizes the waterplane area and cut the water surface unaffected of waves and wave resistance. It works like two submarines driving beneath the waves that carrying a platform above the waves, with a constantly horizontal position.
InSvivia's combination of gyroscopic momentum, lowering hull and large scale enable further waterplane area reduction, approximately eliminates wave resistance and pitching. It's like a submarine-borne platform.
SWATH's maintains a horizontal position in wave heights up to the distance between the hulls and the platform. InSvivia's ship is designed for more than 10 meters waves, and cross the Pacific in 2,5 days with great weather overview.
The disadvantage for SWATH ships is increased hull surface and friction. InSvivia's patented technology is the solution of this disadvantage.
The air has an 800 times lower density than water, and reduce the friction equivalent.
Air lubrication in too low velocity goes in uncontrolled directions and the air fraction becomes too low.
In a velocity that is high enough, the air follows the implosion power of the cavitation for a clean fraction.
20 mm cavitator steps in 10 meters intervals injects an air cover to cancel all friction.
The angular momentum of InSvivia's rotating hull stabilizes the ship like a spinning projectile, and makes a high tolerance for all vertical and sideway impacts. The stabilization maintains an ultra-high efficiency of supercavitation with maximized air fraction.
AIR FROM START TO END
Two compressors obtain air from the air resistance and supplies the hull with a moderate pressure. Cavitator steps open nozzles to a ventilated cavitation, and eliminates water friction. The angled hull surfaces make a rotary regulative stable pressure distribution.
INSVIVIA SCREW DESIGN
Screw design is known back to the 20’s as propulsion, where a blade goes in a spiral around an inner cylindrical hull. All cylindrical parts represents friction in the rotation direction and affects the flow pattern. InSvivia's patented star-shaped cross section avoid all rotation friction.
Two waterjets operates the ship with high propulsion efficiency.
THE HULL ROTATION
Thrust of 10 % of total propulsion force operates the hull to a positive torque, and makes a controlled pressure distribution with minimized pressures.
The air compressors in the front of the ship uses electric power obtained from the propulsion engines.
CFD-Analysis shows fuel reductions of 74 %. The fuel reduction consists four parts:
The friction represents more than 90 % of total resistance for slow-steaming ships. InSvivia cancel the friction by supercavitation.
2. WAVE RESISTANCE
The wave resistance increases exceptionally in high speed. The SWATH design makes it insignificantly.
3. VERTICAL MOVEMENTS
Mono-hulls have up to 50 % additional resistance in rough sea because of pitching & vertical movements. The SWATH is stable.
Mono hulls makes huge volume differences in waves where the construction has to resist the lack of buoyancy in decreasing waves. Vertical movements and vibrations make a large degree of steel fatigue.
The more bending moments, the more steel is required to resist the moments, and the construction becomes equally heavier.
Large mono hulls has up to hundred thousand cubic of volume differences in high waves, tensioned over hundred of meters.
A SWATH with minimal waterplane area avoids potentially more than 90 % of the bending moments in large ship scale.
InSvivia is the decidely most eco-friendly shipping project ever. Not only in 74 % directly emission savings, but also outperforming of the 100 times more polluting air transport.
REDUCED AIR TRANSPORT
SHIP PRODUCTION EMISSION
STEEL CONSUMPTION PER SHIP
By cruising five times faster and transporting four times more load amount than current ships, InSvivia reduce the ship production demand with 75 %. Additionally, the reduced bending moments reduces the steel consumption with more than 45 % per ship.
WHAT IS CAVITATION?
Supercavitation is the use of cavitation effects to create a bubble of gas inside a liquid large enough to encompass an object travelling through the liquid, greatly reducing the skin friction drag on the object and enabling achievement of very high speeds.
SWATH & TORPEDO USE
Supercavitation is extensive used on the submarine projectiles Shkval Torpedo. The supercavitating SWATH GHOST, verify the functionality. InSvivia's speed-provoked supercavitation increase the efficiency to a stabilized ship construction with minimal adverse of pressures.
CAVITATING CARGO SHIP
Project called Resonance-Free SWATH, leaded by universities and professors, want to use supercavitation on a 230 metres long containership. InSvivia is the solution for a stabilized construction with permanently and controlled efficiency of supercavitation.
