Description

DESCRIPTION

WOBBLE REDUCING SYSTEM IN MARITIME VESSELS The Related art

The invention relates to a system that is applicable to floating bodies like yatches, boats by earning controlled motion feature via a servo system to the secondary hulls found in trimaran vessel structure, in order to prevent floating bodies like yatches, maritime vessels from affected by the waves and to reach a much higher cruising speed with lower fuel consumption.

The Prior Art

In existing systems, even in cases where a vessel is not under way (moored to a piece of land or is at anchor) wobble is continuous and shortens the lifetime of the vessel, causing it to become worn, destroying the comfort therein and may lead to health problems. In the production process, hardships emerge in design, living quarters, engineering works of vessel aimed to reduce wobble to minimum.

Again, another method used in the prior art for the stabilisation of a vessel is gyroscope. Gyroscope on the other hand is an instrument used for measurement or adjustment of direction, used for the purpose of angular stabilisation, working with the principle of preservation of angular stabilisation. Although this method harnesses wave effect at 55%, a vessel is still exposed to wave effect at the rate of 45%. A further method on the other hand is stabiliser wings. They are oriented outward by the side of a vessel like the wings of a plane, reducing the effect of waves, however, wave effect still continues. In addition, including catamaran, not any other method can reduce bow and stern wave effect. In conclusion, existence of the requirement for the systems created to prevent floating bodies like yatches, maritime vessels, ships, etc. from being affected by the waves, minimising wobble and wave absorption applied via adding secondary bodies to trimarans, and inadequacy of the existing solutions have made it necessary to make a development in the respective related art. Purpose of the Invention

The present invention relates to a system meeting the above disclosed requirements, eliminating all the disadvantages and introducing some additional advantages, reducing wave-induced wobble, lowering the cost of fuel and increasing the speed.

A purpose of the invention is to get into use a wobble reducer system used in floating crafts and providing reduction of wobble induced by the waves. Another purpose of the invention is development of system having low-cost and eliminating living quarters losses, in stead of costly applications made in order to reduce a vessel from being affected by the waves.

Another purpose of the invention is elimination of wobble problem of existing maritime vessels and clearing the roadblocks for design, production, engineering works of a vessel that will be newly built. To achieve this, the system will be applied to the secondary bodies of trimarans, secondary bodies of trimarans run with a servo system so that a vessel is not affected by the waves by means of a servo system. Thus, minimisation of wobble is aimed.

Another purpose of the invention is reduction of friction effect of a vessel by lifting it up from the water line at high speeds, reducing fuel consumption in parallel with this. Since the craft will not have to use power against the waves, amount of the fuel used is decreased.

Another purpose of the invention is also successful reduction of minimising the bow and stern wave effect, including port starboard.

Another purpose of the invention on the other hand is it becomes adapted to other stabilisation methods, by choice and its usability with them.

Another purpose of the invention is that it can also be applied during the production process as well as being applicable later to a currently manufactured vessel, yatch. The system, which is the subject of the invention, reducing wobble effect induced by the waves is applied to the secondary bodies of trimaran. These secondary bodies can be attached later to all floating bodies like boats or yatches, turning them into trimarans, minimising being affected by wobble can be achieved.

To achieve the said objectives, the invention is wobble reducing system, for application to sea crafts, comprising

- at least one unit of secondary body connected to both sides of said vessel in a way that can move,

- at least one connector providing connection of said secondary body to the vessel,

A. Wobble reducing system Detailed Description of the Invention

In this detailed description, the preferred features of the wobble reducing system (A), which is the subject of the invention, are described only for a better understanding of the subject-matter and in a way not constituting any limiting effect. The wobble reducing system (A), which is the subject of the invention, has been developed to prevent a vessel (1) cruising on water or moored to a fixed piece of land, anchored at a pontoon from being affected by the waves. Said vessel (1) herein is trimaran. However, in different applications, with application of the secondary bodies (2) to different vessel (1), the system (A) can be used in different vessel (1) like yatches, boats.

Said wobble reducing system (A) comprises

- At least a secondary body (2) connected to the sides of vessel (1) via articulations, that is connectors (5) in a way that is movable,

- At least one actuator (3) that provides closing of the second bodies (2) by turning over the connector (5) in order to prevent said vessel from taking up space and to increase its balance control elasticity,

- At least two vertical actuators (4) that provide up and down movement of bow and stern parts of the said secondary body (2), in order for the second bodies (2) to maintain the balance of the vessel (1) by means of the orders of the servo system controlling the system (A) according to the wave effect coming from bow and stern, port and starboard, and lift the vessel (1) above the water line when desired. Said connector (5) is the articulation that provides movement of the secondary bodies (2) in order to provide movement of the vertical and horizontal actuators (3,4) connected to the secondary body (2) used for maintaining the balance of the vessel (1), according to the coming direction of the wave. The horizontal and vertical actuators (3,4) that are used to prevent the vessel (1 ) from being affected during the wobble induced by the wave move according to the coming direction of the wave on orders they receive from the servo system, on condition that they are applied to the secondary bodies (2) of the vessel (1). These actuators (3,4) may be hydraulic and/or electrically driven pistons. In stead of said pistons, threaded rod or toothed rack drive system can also be used. Thus, while the vertical actuator (4) in one of the secondary bodies (2) wherein the system (A) has been applied gets contracted in cases where the vessel (1) is exposed to wave, the other vertical actuator (4) connected to the same secondary body (2) gets elongated in the same extent. A separate secondary body (2) connected to the other side of the vessel (1) on the other hand prevents wobbling of the vessel (1) due to the wave, acting in a way to create a reaction. In Figure 4 and Figure 5, this situation is exemplified. As seen in Figure 4 and Figure 5, said vertical actuators (4) mounted in at least two units to the secondary body (2) provide that the vessel (1 ) is affected minimum from the wave by making a movement of elongation contraction during a wave coming from the bow and stern and port and starboard. When said vessel (1) needs to be taken to a narrow area, the horizontal actuators (3) in secondary bodies (2) get contracted as seen in Figure 3. By means of the connectors (5), the secondary bodies (2) will approach the body of the vessel (1). Thus, through reduction of the total width of the vessel (1), passing through the narrow areas or location in such areas can be achieved (Figures 10a-10b).

As seen in Figure 6 and Figure 9 wherein a rear, perspective view of the vessel (1 ) is given, when there is not wave thanks to the wobble reducing system (A), the actuators (4) in the secondary bodies (2) ensure the vessel (1 ) to go above the water in high speeds. Thus, friction force of water is reduced and the vessel (1) travels faster. In this way, by reducing the friction, speed of the vessel (1) is increased without requiring excessive power use and fuel consumption economy is achieved.

The wobble reducing system (A), which is the subject of the invention can be applied with the horizontal actuator (3) and the connector (5) (Figures 11a-1 1 b). Thus, during the wave, by means of the connector (5) and the vertical actuators (4) in the secondary body (2), wobbling induced by the waves coming from bow and stern and port and starboard is minimised. By selecting the vertical actuator (4) used at high speed, friction can be reduced by ensuring the vessel (1 ) goes above the water line. And thus, speed increase and fuel economy is made.

Figure, an alternative embodiment of the invention is given. In alternative embodiments of the invention, the system (A) can be materialised via use of multiple secondary bodies to both sides of the vessel.

In a different alternative embodiment of the invention, the number of actuator (3,4) can be in multiple. Or the system (A) can also be created by using one single actuator (3,4) (Figure 8). In a different alternative embodiment of the invention, for location of the vessel (1 ) in narrow areas, the secondary bodies (2) can also be created in a way opening upwards. Thus, spatial economy will be greater. (Figure 12)

In another different embodiment of the invention, the system (A) can also be positioned at front, lower section of the vessel (1 ) body. It can also be applied by adding an additional body (2) positioned via centring the vessel (1 ) by the starboard- port side. Apart from this, while the body (2) in the middle is in the rear section of the vessel (1 ), the side bodies (2) can be located in the front part of the vessel (1) (Figures 13a and 13b).

With the application above, the vessel (1 ) rests on three bodies (2). Thus,, the vessel (2) has a much more balanced structure. In addition, it is less affected by the waves coming from the bow -stern, compared to the crafts (1 ) having two side bodies.

In another alternative embodiment of the invention, it can be materialised via a mechanism that provides opening of the secondary bodies (2) outward from the body of the vessel (1 ) (Figure 14). Connection ways of the actuators (3,4) used in different applications of the invention may show varieties. Connection means can be utilised in a suitable manner like vertical, horizontal, diagonal, etc..
