Buque catamaran OBJETO DE LA INVENCIONCatamaran vessel OBJECT OF THE INVENTION
La presente invencion pertenece al sector nautico, y mas concretamente a buques o embarcaciones especialmente adaptadas o disenadas para fines particulares.The present invention belongs to the nautical sector, and more specifically to ships or vessels specially adapted or designed for particular purposes.
El objeto de la presente invencion es un buque catamaran que permite una mejora sustancial de la estabilidad y el comportamiento de la embarcacion ante condiciones adversas de navegacion de fuerte oleaje, consiguiendo absorber los impactos del mar, reduciendo y amortiguando los movimientos de cabeceo, y en consecuencia evitando danos en la estructura de la embarcacion.The object of the present invention is a catamaran vessel that allows a substantial improvement in the stability and behavior of the vessel in the face of adverse conditions of strong waves, managing to absorb the impacts of the sea, reducing and damping the pitching movements, and in consequence avoiding damage to the structure of the boat.
ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
En la actualidad son ampliamente conocidas las embarcaciones o buques del tipo catamaran, los cuales estan constituidos basicamente por dos cascos o patines laterales, entre las cuales existe un puente o cuerpo central, situado a una altura elevada respecto de los cascos laterales, y por el cual circula el agua del mar. Estos dos cascos laterales permiten cortar el mar en dos lmeas paralelas, lo cual ha permitido catalogar a los buques catamaran como una de las embarcaciones que mejor comportamiento y estabilidad presentan durante su navegacion, y donde ademas, a diferencia de las embarcaciones monocasco, a igualdad de condiciones de eslora, se ha comprobado que los buques catamaran obtienen mayores velocidades medias.At present, boats or ships of the catamaran type are widely known, which are basically constituted by two hulls or side skates, among which there is a bridge or central body, located at a high height with respect to the side hulls, and by the which circulates the sea water. These two side hulls allow the sea to be cut into two parallel lines, which has allowed catamaran ships to be cataloged as one of the vessels that have the best performance and stability during their navigation, and where also, unlike monohull vessels, equally In terms of length, it has been proven that catamaran vessels obtain higher average speeds.
Este tipo de buques catamaran se emplean, ademas de para su disfrute en rutas turisticas de ocio, para navegar por mares de gran oleaje, siendo incluso empleado para realizar tareas de mantenimiento en alta mar, por ejemplo en parques eolicos, donde los aerogeneradores se encuentran instalados varias millas alejadas de la costa, y donde lo que se busca es obtener una maxima estabilidad de la embarcacion para evitar cualquier posible accidente o caida de los operarios al mar.This type of catamaran ships are used, in addition to its enjoyment in tourist leisure routes, to navigate high seas, being even used to perform maintenance tasks on the high seas, for example in wind farms, where wind turbines are located installed several miles away from the coast, and where what is sought is to obtain maximum stability of the boat to avoid any possible accident or fall of the operators to the sea.

Cabe citar por ejemplo la patente espanola ES2234360 B2, en la cual se describe un buque tipo catamaran, provisto de dos cascos laterales adelantados con respecto a un cuerpo central, contando ademas con un par de ventanas laterales para la evacuation del agua del mar.It is worth mentioning, for example, the Spanish patent ES2234360 B2, in which a catamaran ship is described, provided with two forward hulls with respect to a central body, also having a pair of side windows for the evacuation of sea water.
Mas concretamente, en dicha patente ES2234360 B2 la proa del cuerpo central se encuentra en una position retrasada o “retranqueada” con respecto a las proas de los cascos laterales, tal y como refleja claramente su figura 2. Si bien esta embarcacion cumple con los requisitos basicos de navegacion, se ha comprobado que su particular disposition de la proa central situada en posicion retranqueada hacia atras continua teniendo varios problemas e inconvenientes en cuanto a la estabilidad y el comportamiento del barco en condiciones extremas de navegacion, como por ejemplo oleajes de fuerza 8 (mar muy gruesa), por lo que dicha embarcacion no es homologable para tareas de exigencia maxima en cuanto a estabilidad, tales como tareas de mantenimiento, reparation y/o instalacion de torres eolicas en alta mar.More specifically, in said patent ES2234360 B2 the bow of the central body is in a delayed or "retracted" position with respect to the bows of the side hulls, as clearly shown in its figure 2. Although this vessel meets the requirements Basic navigation, it has been proven that its particular disposition of the central bow located in the backward position continues to have several problems and disadvantages in terms of the stability and behavior of the ship in extreme navigation conditions, such as force waves 8 (very thick sea), so that vessel is not homologated for tasks of maximum requirement in terms of stability, such as maintenance, repair and / or installation of wind towers on the high seas.
DESCRIPCION DE LA INVENCIONDESCRIPTION OF THE INVENTION
Mediante la presente invention se solucionan los inconvenientes anteriormente citados proporcionando un buque catamaran que permite una mejora sustancial de la estabilidad y el comportamiento de la embarcacion ante condiciones adversas de navegacion de fuerte oleaje, consiguiendo reducir y amortiguar los movimientos de cabeceo de la embarcacion derivados de las fuertes batidas e impactos del mar, soportando incluso situaciones de oleaje con mar muy gruesa de hasta fuerza 8, y en consecuencia evitando danos en la estructura inferior de la embarcacion.By means of the present invention, the aforementioned drawbacks are solved by providing a catamaran vessel that allows a substantial improvement in the stability and behavior of the vessel in the face of adverse conditions of strong swell navigation, managing to reduce and dampen the pitching movements of the vessel derived from the strong beats and impacts of the sea, withstanding even swell situations with very thick sea of up to force 8, and consequently avoiding damage to the lower structure of the boat.
El buque catamaran de la invencion comprende un par de cascos laterales dispuestos en posicion paralela entre si, un cuerpo central situado entre dichos cascos laterales, donde la superficie inferior del cuerpo central se encuentra a una altura superior respecto de la superficie inferior de los cascos laterales, con la particularidad de que los cascos laterales y el cuerpo central tienen sus extremos superiores de proa alineados con respecto a una misma lmea horizontal imaginaria situada en el extremo superior delantero del buque catamaran.The catamaran ship of the invention comprises a pair of side hulls arranged in parallel position with each other, a central body located between said side hulls, where the lower surface of the central body is at a higher height with respect to the lower surface of the side hulls , with the particularity that the side hulls and the central body have their upper bow ends aligned with respect to the same imaginary horizontal line located at the upper front end of the catamaran ship.

Esta especial disposition de forma paralela y alineada de los extremos superiores de los cascos laterales y el cuerpo central permite "atacar” o romper la ola en hasta tres puntos diferentes, consiguiendo de esta manera reducir la intensidad y virulencia del oleaje, y en consecuencia, no afectando a la estabilidad de la embarcacion, perfeccionando asi su navegabilidad.This special arrangement in parallel and aligned with the upper ends of the side hulls and the central body allows to "attack" or break the wave at up to three different points, thus reducing the intensity and virulence of the waves, and consequently, not affecting the stability of the boat, thus improving its navigability.
Preferentemente, se ha previsto que los cascos laterales puedan comprender unas protuberancias de ataque de oleaje, situadas en sus extremos inferiores de proa, y que proporcionan al buque catamaran un empuje adicional que amortigua los movimientos de cabeceo y por tanto, reduce la intensidad de los golpes de mar en la estructura de proa del barco.Preferably, it is provided that the side hulls may comprise swell attack protuberances, located at their lower bow ends, and that provide the catamaran with an additional thrust that dampens pitching movements and therefore reduces the intensity of the sea blows on the ship's bow structure.
Ademas, se contempla la posibilidad de que tanto los cascos laterales como el cuerpo central puedan disponer adicionalmente de unos nervios salientes perimetrales, que se extienden de proa a popa a lo largo de toda su longitud, y que sobresalen levemente hacia fuera respecto de la superficie externa de dichos cascos laterales y cuerpo central. Estos nervios salientes, o "codillos”, favorecen la amortiguacion de los molestos movimientos de cabeceo de la embarcacion, ayudando a contener la subida del "spray” o masa de agua espumosa producida por el impacto de las olas contra la quilla de la embarcacion, permitiendo mejorar mas aun si cabe la estabilidad del buque.In addition, the possibility is contemplated that both the lateral helmets and the central body may additionally have perimeter projection ribs, which extend from bow to stern along their entire length, and that slightly protrude outward from the surface external of said lateral helmets and central body. These protruding nerves, or "knuckles", favor the cushioning of the annoying movements of pitching of the boat, helping to contain the rise of the "spray" or mass of foamy water produced by the impact of the waves against the keel of the boat, allowing to improve even more if the stability of the ship fits.
Asimismo, de acuerdo con otra realization preferente, el buque catamaran aqu descrito puede comprender adicionalmente un par de alerones, cada uno de ellos dispuestos entre uno de los cascos laterales y el cuerpo central, y que preferentemente tienen una forma de "T” invertida. Estos alerones permiten absorber la mayor parte del impacto del mar, evitando asi danos en la estructura inferior de la embarcacion en la zona de proa.Also, according to another preferred embodiment, the catamaran ship described herein may additionally comprise a pair of ailerons, each arranged between one of the side hulls and the central body, and preferably having an inverted "T" shape. These ailerons allow to absorb most of the impact of the sea, thus avoiding damage to the lower structure of the boat in the bow area.

REALIZACION PREFERENTE DE LA INVENCIONPREFERRED EMBODIMENT OF THE INVENTION
Se describe a continuation un ejemplo de realization preferente haciendo mention a las figuras arriba citadas, sin que ello limite o reduzca el ambito de protection de la presente invencion.An example of preferred realization is described below, mentioning the above-mentioned figures, without limiting or reducing the scope of protection of the present invention.
En la figura 1 se puede apreciar el buque catamaran (1) de la invencion, el cual comprende:In figure 1 you can see the catamaran ship (1) of the invention, which comprises:
- un par de cascos laterales (10) en disposition paralela, y que disponen de unas protuberancias (13) de ataque de oleaje, situadas en sus extremos inferiores de proa, y que en el presente ejemplo tienen una configuration puntiaguda, con su vertice (13A) orientado en el sentido de avance de navegacion, tal y como se representa en las figuras 1, 2 y 3;- a pair of side helmets (10) in parallel arrangement, and having swell attack protuberances (13), located at their lower bow ends, and which in the present example have a pointed configuration, with its vertex ( 13A) oriented in the direction of navigation progress, as shown in Figures 1, 2 and 3;
- un cuerpo central (20), mostrado en las figuras 1 y 2, situado entre los cascos laterales (10), donde la superficie inferior del cuerpo central (20) se encuentra a una altura superior respecto de la superficie inferior de los cascos laterales (10);- a central body (20), shown in figures 1 and 2, located between the side helmets (10), where the lower surface of the central body (20) is at a higher height than the lower surface of the side helmets (10);

- un par de alerones (30), estando cada uno de dichos alerones (30) situado entre uno de los cascos laterales (10) y el cuerpo central (20), y que en esta realization preferente tienen una forma de "T” invertida, tal y como se observa en las figuras 1 y 2; y- a pair of ailerons (30), each of said ailerons (30) being located between one of the side helmets (10) and the central body (20), and which in this preferred embodiment have an inverted "T" shape , as seen in Figures 1 and 2; and
- unas ventanas laterales (40), mostradas en las figuras 1 y 3, para la evacuation y salida del agua de mar circulante entre dichos cascos laterales (10).- side windows (40), shown in figures 1 and 3, for the evacuation and exit of circulating sea water between said side hulls (10).
Asi, en las figuras 1, 2 y 4 se puede observar que los cascos laterales (10) y el cuerpo central (20) tienen sus extremos superiores de proa (11, 21) alineados con respecto a una misma lmea horizontal (H) imaginaria situada en el extremo superior delantero del buque catamaran (1). Esta particular disposition permite que, ante condiciones de navegacion extremas de fuerte oleaje, la ola sea atacada al mismo tiempo por tres zonas distintas, esto es, tanto por los cascos laterales (10) como por el cuerpo central (20), lo cual tiene importantes consecuencias beneficiosas, como son: una reduction sustancial de la fuerza e intensidad con que impactan las olas contra la embarcacion, y por tanto, una notable mejora de la estabilidad de la misma.Thus, in Figures 1, 2 and 4 it can be seen that the lateral hulls (10) and the central body (20) have their upper bow ends (11, 21) aligned with respect to the same imaginary horizontal line (H) located at the upper front end of the catamaran ship (1). This particular provision allows that, under extreme surfing conditions, the wave is attacked at the same time by three different zones, that is, both by the side hulls (10) and by the central body (20), which has important beneficial consequences, such as: a substantial reduction in the force and intensity with which the waves impact the vessel, and therefore, a marked improvement in its stability.
Por otro lado, en las figuras 1 y 2 se aprecia que tanto los cascos laterales (10) como el cuerpo central (20) tienen unos nervios salientes (12, 22) perimetrales, que se extienden de proa a popa a lo largo de toda su longitud, y que sobresalen levemente hacia fuera respecto de la superficie externa de dichos cascos laterales (10) y cuerpo central (20). Estos nervios salientes (12, 22) o "codillos”, permiten amortiguar los movimientos de cabeceo de la embarcacion y taponar la subida del "spray” o masa de agua procedente de la ola, por lo que la intensidad de los golpes del mar sobre la estructura de proa se ve reducida.On the other hand, in Figures 1 and 2 it can be seen that both the lateral helmets (10) and the central body (20) have perimeter ribs (12, 22), which extend from bow to stern throughout the entire their length, and slightly protruding outward from the outer surface of said lateral helmets (10) and central body (20). These outgoing ribs (12, 22) or "knuckles", allow to dampen the movements of pitching of the boat and plug the rise of the "spray" or mass of water from the wave, so that the intensity of the blows of the sea on the bow structure is reduced.
Mas en particular, en las figuras 1, 2 y 3 se observa que los nervios salientes (12) perimetrales de los cascos laterales (10) se encuentran situados a una altura que coincide con el vertice (13A) de las protuberancias (13) de ataque de oleaje. Esta particularidad permite maximizar la absorcion y amortiguacion de los movimientos de cabeceo de la embarcacion, teniendo asi un maximo perimetro de actuation sobre el mar.More particularly, in Figures 1, 2 and 3 it can be seen that the perimeter ribs (12) perimetral of the lateral hulls (10) are located at a height that coincides with the vertex (13A) of the protuberances (13) of swell attack. This particularity allows maximizing the absorption and damping of the movements of pitching of the boat, thus having a maximum perimeter of actuation over the sea.
Respecto a los alerones (30) con forma de "T” invertida, estos permiten obtener dos ventajas significativas: por un lado permiten absorber los fuertes impactos del mar, actuando como elementos de contention, por lo que la estabilidad de la embarcacion no se ve afectada al mismo tiempo que se evitan danos en la estructura del barco en su parte de 5 proa; y por otro lado permiten una optima distribution y canalization de la ola atacada, quedando esta ultima dividida y en consecuencia reduciendo su fuerza e intensidad.Regarding the ailerons (30) with an inverted "T" shape, these allow two significant advantages to be obtained: on the one hand they allow the strong impacts of the sea to be absorbed, acting as contention elements, so that the stability of the boat is not visible affected at the same time that damage to the structure of the ship in its part of 5 bow is avoided; and on the other hand they allow an optimal distribution and canalization of the attacked wave, the latter being divided and consequently reducing its strength and intensity.
No obstante lo anterior, de acuerdo con otra realization preferente no representada, se ha previsto que dichos alerones (30) puedan presentar otra forma, tal como una configuration 10 en "U”, con sus dos ramas laterales unidas a la superficie inferior del casco superior delantero del buque catamaran (1). Con esta disposition de los alerones (30) se conseguiria una triple difusion o separation de la portion de agua entrante entre cada casco lateral (10) y el cuerpo central (10).Notwithstanding the foregoing, in accordance with another preferred embodiment not shown, it is provided that said spoilers (30) may have another shape, such as a "U" configuration 10, with their two lateral branches attached to the lower surface of the hull upper front of the catamaran vessel (1) With this arrangement of the ailerons (30) a triple diffusion or separation of the incoming water portion between each side hull (10) and the central body (10) would be achieved.
15 Por tanto, mediante el buque catamaran aqu descrito, se proporciona una embarcacion especialmente adaptada para una optima navegabilidad incluso en situaciones de "mar arbolada” o "mar gruesa”, donde la fuerza del viento es muy elevada (igual o superior a 8), permitiendo mantener en todo momento la estabilidad de la embarcacion, haciendolo particularmente apto e interesante para tareas y trabajos en alta mar, por ejemplo labores 20 de mantenimiento de torres eolicas, donde cualquier mmimo escorado, inclination o desequilibrio del buque podria tener fatales consecuencias, como la caida de un hombre al mar.15 Therefore, by means of the catamaran vessel described here, a boat specially adapted for optimum navigability is provided even in situations of "wooded sea" or "coarse sea", where the wind force is very high (equal to or greater than 8) , allowing to maintain the stability of the boat at all times, making it particularly suitable and interesting for tasks and works on the high seas, for example, work 20 of maintenance of wind towers, where any minimum chosen, inclination or imbalance of the ship could have fatal consequences, Like a man's fall to the sea.
