ABSTRACT

Due to the two unique active and passive stabilization features of the preferred embodiment of Spinning Stabilized Ship, of which the first feature is a marine vessel, spherical monohull, surface ship and it is combined with the second feature of spinning the entire ship for stabilization, act together for extraordinary stability. The preferred embodiment of a spherical Spinning Stabilized Ship utilizes the entire spherical Spinning Stabilized Ship as a giant, slow spinning, gyroscope to achieve unparalleled stabilization. The preferred embodiment is a spherical Spinning Stabilized Ship which eliminates bows, sterns, starboard sides, port sides, external decks, superstructures, keels; and eliminates orientation along a horizontal central longitudinal axis between bows and sterns and also nearly eliminates all motions such as yaw, pitch, roll, heave, sway and surge caused by waves throughout the Beaufort Extended Scale numbers 0-17. The preferred embodiment is a spherical Spinning Stabilized Ship, which creates great stabilization when Beaufort Extended Scale numbers 0-17 increase in magnitude, these motions are nearly eliminated and prevent catastrophic capsizing, sinking, hull fracture, hull separation, broaching, pitchpoling, swamping, etc.  

BACKGROUND

Most marine vessel surface ships, whether they are monohulls, multihulls, displacement hulls, planing hulls or semi displacement hulls, have bows, sterns, starboard sides,  port sides, external decks, superstructures, and keels; and these features are oriented along their horizontal central longitudinal axis between their bows and their sterns. Most marine vessel surface ships are sensitive in how they orient themselves to waves that may occur in Beaufort Extended Scale numbers 0-17 and this sensitivity increases dangerously as Beaufort Extended Scale numbers increase and wave size increases. Most marine vessel surface ships have motions such as yaw, pitch, roll, heave, sway and surge caused by waves throughout the Beaufort Extended Scale numbers 0-17. As Beaufort Extended Scale 0-17 numbers increase in magnitude, these motions also increase in magnitude and can cause catastrophic capsizing, sinking, hull fracture, hull separation, broaching, pitchpoling, swamping, etc. A spherical Spinning Stabilized Ship is not sensitive to how it orients itself to waves that occur in Beaufort Extended Scale numbers 0-17. A spherical Spinning Stabilized Ship is insensitive to how it orients itself to waves. A spherical Spinning Stabilized spherical Spinning Stabilized Ship with its infinite continuous rotational symmetry; eliminates bows, sterns, starboard sides, port sides, external decks, superstructures, keels; and eliminates orientation along a horizontal central longitudinal axis between bows and sterns; and also nearly eliminates all motions such as yaw, pitch, roll, heave, sway and surge caused by waves throughout the Beaufort Extended Scale numbers 0-17. The two unique stabilization features of a spherical Spinning Stabilized Ship; which are that the entire ship is a sphere with infinite continuous rotational symmetry and that the entire ship is spinning to create gyroscopic stabilization for the entire ship; and they can act, at will, simultaneously together and when Beaufort Extended Scale numbers increase in magnitude, these motions are nearly eliminated and prevent catastrophic capsizing, sinking, hull fracture, hull separation, broaching, pitchpoling, swamping, etc. A third unique stabilization feature is when the entire ship is spinning for stabilization the entire ship can simultaneously navigate a course in all sea conditions.

        SUMMARY

Spinning Stabilized Ship, which is a spinning marine vessel, spherical monohull and a surface ship, and is not oriented along a horizontal central longitudinal axis. The preferred embodiment of this invention which is named, Spinning Stabilized Ship, and is a spinning marine vessel, spherical monohull, surface ship and; has the feature of spinning the entire spherical monohull, marine vessel, and surface ship for gyroscopic stabilization. Spinning Stabilized Ships must be able to navigate with their spinning marine vessel, spherical monohull and surface ship when activated or deactivated, at will. Spinning Stabilized Ship's loaded displacement tonnage weight must be evenly distributed and be well balanced around its central vertical axis. Spinning Stabilized Ship serves in its entirety as its single buoyant structure. The fact that a spherical Spinning Stabilized Ship is insensitive to how it orients itself to waves that occur in Beaufort Extended Scale numbers 0-17 is because its spherical geometric shape is exactly why the ship is insensitive to how it orients to all waves. Therefore a spherical Spinning Stabilized Ship with its infinite continuous rotational symmetry, eliminates bows, sterns, starboard sides, port sides, external decks, superstructures, keels; and eliminates orientation along a horizontal central longitudinal axis between bows and sterns and also nearly eliminates all motions such as yaw, pitch, roll, heave, sway and surge caused by waves found throughout the Beaufort Extended Scale numbers 0-17. The stabilizing features of spherical Spinning Stabilized Ship act together; when Beaufort Extended Scale numbers increase in magnitude; and then these motions are nearly eliminated and prevent catastrophic capsizing, sinking, hull fracture, hull separation, broaching, pitchpoling, swamping, etc. 

DETAILED DESCRIPTION

The preferred embodiment of Spinning Stabilized Ship is a spinning marine vessel, spherical monohull and surface ship which has infinite continuous rotational symmetry and has interior multiple decks that would generally have spaces for propulsion, navigation, shelter wet decks for work, shelter wet decks for recreation, machine shop, hatch covered or uncovered helipad, helm, fuel tanks, passenger and crew quarters, galley, heads, pools, hot tubs, saunas, gyms, libraries, theaters, desalination freshwater system, sewage treatment system, auxiliary craft launch and haul out wet deck, etc. Customized versions  of Spinning Stabilized Ship, could be built as marine vessels such as a customized explorer super yacht, a research vessel, naval vessel, cruise ship, coastguard vessel, commercial fishing vessel, other types of commercial vessels; and they all would act as a giant spinning gyroscope for stabilization which is a unique approach to ship design compared to other traditional surface ships. There are a number of non-preferred embodiments as non-spherical Spinning Stabilized Ship variations which do not have infinite continuous rotationally symmetry. One can build, within the scope of this invention, a non-spherical  Spinning Stabilized Ship only if its geometric shape has continuous rotational single axial symmetry to allow for the spinning of the entire spinning marine vessel, non-spherical monohull, surface ship. The single preferred embodiment as well as non-preferred embodiments of Spinning Stabilized Ship have azimuthing omnidirectional thrusters which are marine propulsion units; housed in exterior or interior mounted steerable pods; that can rotate a full 360 degrees. By directing thrust in any horizontal direction, they eliminate the need for traditional rudders, providing vessels with unprecedented pinpoint maneuverability. Multiple azimuthing omnidirectional thrusters are capable of generating and directing horizontal thrust in a full 360 degree range of direction and are mounted on the bottom of Spinning Stabilized Ship's spherical or non-spherical variations. Azimuthing omnidirectional thrusters are programmed to synchronously generate horizontal thrust for spinning the Spinning Stabilized Ship's entirety around its central vertical axis which generates gyroscopic stabilization and also generate directional horizontal propulsion with a 360 degree range of propulsive horizontal thrust to propel, at will, Spinning Stabilized Ship in any direction. Spinning Stabilized Ship can generate a 360 degree range of directional horizontal propulsive thrust when it isn't spinning, at will. Spinning Stabilized Ship  can generate horizontal propulsion for spinning its entirety for stabilization when the Spinning Stabilized Ship is not making way, at will, and it is holding a fixed position or just drifting. Spinning Stabilized Ship's loaded total displacement tonnage weight must have balanced weight distribution around its central vertical axis. Spinning Stabilized Ship's loaded displacement tonnage weight must also be distributed so the entire ship is counterbalanced with more weight concentrated towards the bottom of the ship and less weight towards the top of the ship; therefore creating a sufficiently strong self-righting moment which makes the entire ship self-righting. Spinning Stabilized Ship's size should be large enough to spin its entire mass at a gyroscopic spinning rate of speed which is tolerable and safe for humans onboard without generating dangerous excessive centrifugal force inside the interior of the spinning marine vessel, spherical monohull, surface ship. An example of just one preferred embodiment would be a 100 foot in diameter spherical Spinning Stabilized Ship according to Froude's law, the hull speed would be approximately 12.83 knots or (14.77 mph). It would spin at one full rotation per minute at approximately (3.6 mph) along the circumference at the equator of the interior. All the following Interior space measurements are approximate measurements. All interior space for passengers and crew, would have six decks of interior space with 37,364 square feet of deck space. These six decks individually are deck five 7536 square feet, deck six 7850 square feet, deck seven 7536 square feet, deck eight 6592 square feet, deck nine 5024 square feet and deck ten 2826 square feet. The seven upper decks are above the waterline. Interior lower four decks  house fuel tanks and entire propulsion system. The three lowest decks of the lower four decks are below the waterline. The number of azimuthing omnidirectional thrusters that are mounted on the bottom of Spinning Stabilized Ship depends on the size and weight of the fully loaded spinning marine vessel, spherical monohull and surface ship and the amount of thrust  required to be generated by the azimuthing omnidirectional thrusters. A Spinning Stabilized Ship in its entirety serves as the vessel's single buoyant structure. The preferred embodiment is a spherical Spinning Stabilized Ship which has infinite continuous rotational symmetry around an infinite number of axes. No matter how you tilt or spin a spherical Spinning Stabilized Ship, it presents the same profile from every angle. A three dimensional spherical Spinning Stabilized Ship has infinite rotational symmetry because every single point on its surface is exactly the same distance from its center. Because it lacks edges, corners, or flat faces, you can spin a spherical Spinning Stabilized Ship around any axis and by any angle and it will look completely identical to its starting position. spherical Spinning Stabilized Ship is defined as the set of all points in three dimensional space that are a fixed distance, the radius, from a single central point. Because there is no "preferred" direction or side, changing its orientation does not change the shape. You can draw an infinite number of imaginary axis lines straight through the center of spherical Spinning Stabilized Ship. No matter which of these axes you choose to spin spherical Spinning Stabilized Ship around, its appearance remains unchanged. Therefore since a spherical Spinning Stabilized Ship only spins on one engineered specific central vertical axis its appearance remains unchanged. The core difference between infinite continuous rotational symmetry and continuous rotational symmetry is the scope of the rotational freedom. Three dimensional infinite continuous rotational symmetry refers to full spherical symmetry where an object is invariant under rotation about any arbitrary axis, whereas three dimensional continuous rotational symmetry generally describes axial symmetry restricted to rotation around a single specific axis. Therefore a spherical Spinning Stabilized Ship, with its infinite continuous rotational symmetry; eliminates bows, sterns, starboard sides, port sides, external decks, superstructures, keels; and eliminates orientation along a horizontal central longitudinal axis between bows and sterns; and also nearly eliminates all motions such as yaw, pitch, roll, heave, sway and surge caused by waves throughout the Beaufort Extended Scale numbers 0-17. The stabilization features of a spherical Spinning Stabilized Ship which is a spinning marine vessel, spherical monohull and surface ship; act together when Beaufort Extended Scale numbers increase in magnitude, these motions are nearly eliminated and prevent catastrophic capsizing, sinking, hull fracture, hull separation, broaching, pitchpoling, swamping, etc. The non-preferred embodiments of non-spherical  Spinning Stabilized Ships will be sensitive to their orientation to waves and will have less elimination of all motions such as yaw, pitch, roll, heave, sway and surge caused by waves throughout the Beaufort Extended Scale numbers but will to a lesser degree perform as a Spinning Stabilized Ship.
