Survey) of ships, its main field of application or utility being that of the
inspeccion/control de cargas y descargas de buques para la determinacion de la carga que transporta mediante la tecnica denominada "Peso por Calados” o "Draft Survey”.inspection / control of cargoes and unloadings of ships for the determination of the cargo transported by the technique called "Weight per Draft" or "Draft Survey".
5 ANTECEDENTES DE LA INVENCION5 BACKGROUND OF THE INVENTION
Como es sabido, el calado de un buque es la profundidad que alcanza en el agua la parte sumergida del mismo, y mas concretamente, la distancia vertical entre la lfnea de flotacion y quilla.As is known, the draft of a ship is the depth that the submerged part of it reaches in the water, and more specifically, the vertical distance between the floating line and keel.
1010
Los calados se miden en escalas situadas a proa, Popa y Centro de las embarcaciones, en ambos costados babor y estribos, los calados de un buque varfan en funcion de la cantidad/peso de material almacenado en sus bodegas, cantidad de Lastres, deducibles como aceites, combustible, agua dulce, y por la 15 densidad del agua en que el buque este flotando.Drafts are measured on scales located at the bow, stern and center of the vessels, on both sides of the port and stirrups, the draft of a ship varies depending on the amount / weight of material stored in its warehouses, quantity of ballasts, deductible as oils, fuel, fresh water, and the density of water in which the ship is floating.
Sin embargo, la observacion de las citadas escalas para poder realizar las mediciones de calado no siempre es posible ni se realiza en buenas condiciones, ya sea porque las marcas en el casco estan muy deterioradas y no se aprecian, 20 porque la posicion del observador no es la adecuada o porque las condiciones de visibilidad no lo permiten, bien por falta de luz o bien a causa de espesas nieblas.However, the observation of the aforementioned scales to be able to carry out the draft measurements is not always possible nor is it carried out in good conditions, either because the marks on the helmet are very deteriorated and are not appreciated, 20 because the position of the observer does not It is adequate or because visibility conditions do not allow it, either due to lack of light or because of thick fog.
No obstante, el factor que mas dificulta la medicion del calado de los buques es el oleaje, ya que el movimiento del mar, especialmente en condiciones de marejada, 25 impide determinar un punto concreto de flotacion en las escalas para poder efectuar una lectura precisa y, por tanto, obtener un desplazamiento real dandonos errores de magnitud en la determinacion del peso de la carga final transportada.However, the factor that most difficult the measurement of the draft of the ships is the swell, since the movement of the sea, especially in conditions of swell, 25 prevents determining a specific point of floating on the scales to be able to make an accurate reading and , therefore, to obtain a real displacement giving us errors of magnitude in the determination of the weight of the final transported load.
30 El objetivo de la presente invencion es, pues, dotar al mercado de un dispositivo que facilite la medicion de los calados sin que sea necesario visualizar las escalas del buque y que, independientemente de las condiciones atmosfericas, de luz y30 The objective of the present invention is, therefore, to provide the market with a device that facilitates the measurement of drafts without it being necessary to visualize the scales of the ship and which, regardless of the atmospheric conditions, of light and
del estado de la mar, permita medir con precision los calados del buque y por tanto el calado medio del mismo.of the state of the sea, allow to accurately measure the draft of the ship and therefore the average draft of the same.
