Definitions

  • the present invention relates to a stabilizer system for damping the movement, primarily the rolling, of vessels that are stationary or that are travelling at low speed and, in particular, to a system of this type that, when inactive, does not interrupt the continuity of the vessel hull surface.
  • this type of dynamic stabilizer is effective only when the vessel is moving, and its configuration and arrangement on the hull are usually calculated to have maximum efficiency at cruising speed with small wavelets.
  • retractable dynamic stabilizers have been developed that are housed in the vessel's hull when not in use, but said housing obviously takes space away from inside the hull, their operation, for the rest, being identical to that of the fixed dynamic stabilizers mentioned above.
  • Antirolling tanks known also as “water chambers”, they are usually placed on both sides of the vessel and intercommunicate via a system of tubes and valves. Their function is to damp rolling under all conditions by means of the transfer of fluid from one side of the vessel to the other, thereby creating a righting torque that opposes the rolling movement of the vessel. This is an effective system, although limited in its application, but its installation involves a high level of complexity, takes volume away from inside the hull and also results in a loss of stability torque in certain circumstances.
  • Finned cones this system consists in suspending, from one or both sides of the vessel, a body of substantially conical or frustoconical shape that is closed via its smaller base, that is usually made of metal and provided with hinged fins on its surface and a weight suspended from its lower part.
  • the fins open such that, through the action of weight, the body remains submerged.
  • the drag of the water over the surface of the cone opposes the movement.
  • the object of the present invention is to provide a stabilizer system that is simple and reliable in operation, capable of efficiently reducing the rolling of a vessel that is stationary or that is travelling at low speed without its incorporation adding resistance to forward movement, i.e. without its affecting the speed of the vessel when the system is inactive, in accordance with the characterizing part of Claim 1.
  • the object of this invention is achieved by incorporating, on both sides of the boat, an element substantially like a fin that can adopt a first, active or deployed, position, in which it has a surface sufficient to damp, to the appropriate extent, the rolling of the vessel when the latter is stationary or travelling at low speed, and a second, inactive or non-deployed, position, in which it may be placed by virtue of being hinged by means of a hinge integral with the hull and in which it forms with the latter a surface with no interruption of continuity.
  • each stabilizer element consists essentially of at least one fin E located on each side of the hull C, below the water line, whose configuration is such that, in its inactive, non-deployed (cf. Fig. 1a), condition, in which it is housed in a recess provided in the aforesaid hull C of the vessel, its outer surface is flush with the outer surface of the hull and forms with it a surface without interruption of continuity and with the same profile as said hull C.
  • said stabilizer fins E offer no resistance to the travel of the vessel.
  • Each of said fins E is hinged on an axis XX' (which, in the view in Figs 1a and 1b, would be perpendicular to the plane of the drawing) such that it may be rotated about said axis XX' from the non-deployed position illustrated in Fig. 1a into at least one active, deployed, position as illustrated in Fig. 1b.
  • Said axis XX' is substantially parallel to or forms a slight angle with the horizontal plane of flotation.
  • the hinge articulation whose geometric axis XX' is arranged essentially longitudinally with respect to the hull C comprises a shaft (not shown) supported in rotation at its ends in supports provided on the outside of the housing A and with which said fin E is integral, the leaktightness of said housing A being guaranteed by means of the relevant, customary sealing devices.
  • the travel of said fins E from their first, non-deployed or inactive, position to their second, deployed or active position, and vice versa may be achieved by different means such as electric motors, whose rotation is transmitted to the shaft integral with each fin E via corresponding gears or by means, at least, of a hydraulic cylinder whose shaft is connected to one at least of the ends of said shaft in order to make it rotate.
  • the number of hydraulic cylinders and their arrangement along said shaft will be dictated by the dimensions of the stabilizer fin E.
  • clamping means (not shown) of known type, for the start and finish of travel, enabling each stabilizer fin E to be immobilized securely in its non-deployed and deployed positions, respectively, are provided.
  • the means for actuating each fin E may be provided in order to rotate each fin from, for example, its non-deployed position to at least one deployed position that is intermediate between the non-deployed position and the totally deployed position of each fin E if desired.
  • the aforesaid clamping means must be able to immobilize said fin E in each of said at least one intermediate deployed position.
  • each assembly of the fin E with its rotary shaft and the corresponding actuating and immobilizing means may constitute a stabilizer unit that can be fitted entirely outside the hull, inside said housing for receiving the fin E which, in such a case, will have such dimensions as to receive all the aforesaid stabilizer unit.
  • the fins E In the operating condition of the stabilizer fins E shown in Fig. 1b, said deployed fins being at a specific angle depending on sea conditions and vessel condition, the fins E will generate hydrodynamic resistance forces F, F' that will give rise to a righting moment that will oppose the rolling movement.
  • each of said fins E consists of at least two fin sections hinged such that they can be folded on themselves in order that said fin sections, in the inactive condition, are non-deployed and received in said housing A, said non-deployed sections of the fin E being deployed when the fin is moved from said first, inactive condition to said second, active condition, projecting from said hull C.
  • each stabilizer element has an increased length in its active condition for a housing A of specific dimensions provided in said hull C.
  • the invention covers the possibility of increasing the damping effectiveness of the aforesaid stabilizer elements by means of the induced movement thereof about their axis, opposing the rolling movement, such that the speed of the hydrodynamic flow on the stabilizers is increased and consequently the force opposing rolling thereon.
