The invention relates to a controlling system and method for controlling a floating arrangement, such as a pontoon platform comprising at least one container or advantageously a plurality of interconnected containers. In particularly the invention relates to a controlling system and method for controlling a state of said arrangement.
There is a need for building new constructions e.g. for substituting constructions lost or destroyed for example by earthquakes, natural catastrophe or the like. For example the earthquakes may destroy roads, bridges, buildings, harbours, airfields or other infrastructure completely. In addition after the natural catastrophe there is a great need for building new constructions, which might be a very demanding task, because often even boats are not able to docking and transport building material due to destroyed harbours. Anyway additionally there is also need for new construction for example to wet or swamp like or similar areas, where the new construction should be built very rapidly (often only for few years (meaning semi permanent)).
The invention relates to developing of constructions especially into the areas, where the infrastructure is destroyed by the natural catastrophe or the like, but also to areas for developing new buildings and constructions very rapid way, such as for temporary semi-permanent or permanent constructions, such as permanent or semi-permanent residential and commercial structures and buildings. Especially the invention relates to developing the constructions over the water area by using a pontoon platform and controlling a state of said platform, because for example tidewater or the like the state, such as positioning or draught of the pontoon platform arrangements are easily changed.
An object of the invention is to alleviate and eliminate the problems relating to the known prior art. Especially the object of the invention is to provide a control system for controlling a state of the floating arrangement, such as a pontoon platform comprising a plurality of interconnected containers so that it may remain its state e.g. due to wind, waves, tidewater or so that its state, such as location, position, alignment, tilt, angle of bank or displacement as an example, may be changed as desired.
The object of the invention can be achieved by the features of independent claims.
The invention relates to a controlling system according to claim 1. In addition the invention relates to controlling method according to claim 17.
According to an embodiment of the invention a controlling system is applied for controlling a state of a floating arrangement, such as pontoon platform, comprising at least one container, advantageously a plurality of floating modules or containers coupled or connected with each other. The containers are advantageously shipping or standard freight containers, especially consistent with ISO standard, such as ISO 668 (40 ft or 20 ft or the like) containers or RACE, ACTS, PODS, SECU or EILU containers, at least some of which are adapted to float on water, such that at least lo some of said containers are waterproof containers (floating as such) and/or at least some of the containers comprise a float arrangement. It is to be noted that also other types of containers or modules can also be utilized even if the containers are described in the embodiments. According to an example the containers are modified into a form of floating containers for example by sealing joints and gaps of the container in order to obstruct possible water flow into the container. As an example, also the doors of the container can be replaced by a fixed plate or the like so that a waterproof container is provided, which can float as such.
In addition according to an example the containers may be provided with an intra-container, such as an air inflatable bag, which water-displacing volume can be changed for displacing water from the container when the inflatable bag is filled or for letting more water entering into the container when the inflatable bag is emptied, and thereby manipulating the buoyancy or draft (draught) of the container and thus also the same of the pontoon platform comprising said container(s).
According to an embodiment of the invention the controlling system comprises controllable means for changing the state of at least one container of the floating arrangement and thereby also the state of the floating arrangement comprising said container. The controllable means are for example a controllable valve or vent, pump, a motor with a propeller or turbine, an anchoring system or other controllable means described in this document. The controlling system is advantageously configured to receive current state information related to at least one container, of the float arrangement or environmental state, such as wind, tidewater phase or the like as an example. In addition the controlling system is configured to compare said received state information to desired state information and based on the comparison provide control signal for at least to one controllable means to change the state of the container or arrangement towards said desired state, and again to operate the controllable means of the float arrangement based on said provided control information in order to achieve said desired state. According to an embodiment the controlling system may also receive controlling information (which is then used by the controlling system as said control signal) from a user interface means operated e.g. manually by a user, such as from joystick or the like, or from external systems, whereupon the state of at least one container of the floating arrangement and thereby also the state of the floating arrangement comprising said container can be controlled remotely.
According to an embodiment the floating arrangement comprises at least one intra-container water-displacing volume located in at least one container of the arrangement, and controllable means for changing capacity of at least one of the intra-container water-displacing volume. The intra-container water-displacing volume may be for example a gas- or foam-inflatable gas bag, such as an airbag. Alternatively or in additionally the float arrangement may also comprise a foaming means for at least partially filling an intra-container volume or container with water-displacing foam, for example a chemical agent reacting with water or other water-displacing medium, such as ping-pong balls or other particles or medium with density less than density of water.
According to an embodiment the controlling system is configured to operate the controllable means of the float arrangement based on the provided control information to change the capacity of at least one intra-container water-displacing volume and/or fill an inner volume of the container with water-displacing medium in order to achieve said desired state.
The controllable means may comprise for example a controlled valve or pump for pumping a fluid, such as gas into or out of the container and/or an inflatable bag provided inside the container, and/or for pumping water into or out of the interior of a container and/or said inflatable bag provided inside said container, and thereby manipulating the buoyancy, location, position, alignment, tilt, angle of bank or displacement of the container and thereby also the state of the floating arrangement comprising said container. According to an embodiment the container may comprise also a valve as a controllable means in connection with the inflatable bag, whereupon the controlling system may control the state of the container (e.g. buoyancy) and thereby the floating arrangement state by changing the bag capacity or water via operating said controllable means. When deflating the bag and thereby allowing water flow into the container, the buoyancy is decreased and the container is sink more; and conversely, when inflating the bag and thereby displacing water out of the container the buoyancy is increased and draft decreases (lifting the container higher in the water). The valve may also locate at the container's wall, whereupon the water flow via said valve can be manipulated by said controlling system by opening or closing said valve.
The container of the arrangement may comprise a plurality of the intra-container volumes, such as inflatable bags, which can be operated separately and independently of each other so that the bags located at the first end of the container can be filled differently than the bags located at the second end of the container, whereupon the buoyancy or draft of the container at the first end differs from the same at the second end thereby allowing a tilting or inclination function of the container. The controlling system then advantageously comprises in addition to plurality of the bags also a pump or the like and/or a controlled valve for supplying gas at least into one of the bags or for delivering water into/out of the container and thereby configured for adjusting the tilt, alignment, angle of bank or displacement of the container by means of different buoyancies in different parts of the container.
The containers, controllable means and measuring means for measuring the state information as an example may comprise a ID-means, preferably a wirelessly or remotely readable ID-means. In addition the system advantageously comprises database, where information is coupled with said IDs, such as location and type of the corresponding means. Thus the system may be provided with information related to said ID and location, where the container or the like with said ID locates, as well as information related to type of said container or the like, such as floating container with inflatable bag(s), valve, pump, actuating means, anchoring container, container with motor+propeller or the like as an example. The controlling system is then advantageously configured to determine based on said ID e.g. the location and type of said container in the database arrangement and thereby configured to provide appropriate control signal to particular containers in order to change or remain the state of the particular container and/or the arrangement.
In addition the containers or the arrangement may comprise measuring means for measuring the state of the container or the arrangement, such as a pressure gauge, load gauge, torque force meter, angle meter and/or positioning means, as an example, wherein the measurement of the measuring means is configured to be transferred to the controlling system advantageously with said container ID or location information of the location of said measuring means representing the state information related to said container or the arrangement so that the controlling system is able to receive said state information, compare it to desired state information and based on the comparison to provide control signal for at least to one controllable means to change the state of the container or arrangement, as is described elsewhere in this document.
One of the controllable means of the floating arrangement is the active anchoring system via which the controlling system is also configured to manage the state of the container(s) or the arrangement. The active anchoring system comprises controllable means, such as a piece of support equipment adapted to be variable in length and fitted between at least one floating container and the anchoring means, such as anchoring container or concrete body at the bottom. In this embodiment the controlling system is adapted to tilt the pontoon platform and thereby the floating arrangement e.g. by changing the length of the supporting means, such as winding the rope between the anchoring means and the container by a motor or hydraulically operating the supporting equipment when said supporting equipment is e.g. hydraulically operable supporting means. This is especially important in tidewater areas, whereupon the controlling system may compensate at least partially the tilting effects due to tidewaters by operating the active anchoring system as described above.
In addition the floating arrangement may comprise a) weight measuring equipment for determining a weight arriving on or departing from the floating arrangement, b) measuring equipment for draft or a distance to surface, c) measuring equipment for floating arrangement distortion and/or measuring equipment for wind direction/speed; and wherein said measurement data are configured to be transferred to the controlling system as said current state information related to at least one container, arrangement or the environment so that said controlling system is configured to provide said control information for at least to one controllable means to change the state of the arrangement towards said desired state, so as to achieve a desired draft, direction, displacement, distance to and/or inclination of the container or arrangement from the surface.
Furthermore the controlling system may be configured to control the state via a container comprising moving equipment (e.g. motor+propeller or turbine), by means of which the container or several containers or the floating arrangement is or are adapted to be balanced and/or moved in vertical and/or horizontal direction by the controlling system.
The floating arrangement may also comprise positioning devices, whereby, in response to a signal produced by said positioning devices, the controlling system is configured to control e.g. said moving equipment for enabling the floating arrangement either to remain stationary or to shift over a desired distance in a desired direction, e.g. in order to compensate for shifting caused for example by tidal currents or consistent wind. Alternatively, or in addition, the controlling system may be configured to receive said position information for example from an external system. The position information can be based on video, radar, satellite, laser beaming, depth/draft, radio signal information and/r combination of those, as an example.
The invention offers remarkable advantages over the known prior art solutions, namely at first, when using shipping or standard freight containers, there are essentially no need for transportation of the containers e.g. into the disaster area from outside or abroad, because there are always lots of shipping or standard freight containers all over the world in harbours and transportation, and in addition they are extended quite equally to coastal areas worldwide. For example in 2009 there were over 15 million ISO 668 (40 ft) containers in the transportation worldwide.
In addition the pontoon platform is very quick and easy to build of the standard containers because due to the standard they are very compatible with each other for example with dimensions and strength. Thus the inventive concept of the current invention makes possible to offer and give aid to the disaster area extremely quick, as well as to build essential constructions very easy, such as residential areas, apartments, hospitals, harbours, bridges, a logistics arrangements or airfields.
Furthermore, according to the invention it is also possible to construct a flight support arrangements or military or social infrastructural arrangements, a jetty, a utility work machine platform, a drilling derrick, a bridge building site, temporary structures, a pontoon bridge or a bridge support structures over the pontoon platform constructed from the containers, as is described in this document. Also there is no need for prefabricate containers or store them beforehand, whereupon significant savings can be achieved. The invention enables to achieve a standard construction method of how globally temporary and permanent floating platforms can be made and thereby helps to organize international aid work, for example. In addition permanent and semi permanent residential and commercial structures and buildings can easily be constructed according to the embodiments of the invention. One possible destination is also to construct a floating farming or plant grooving platforms. Especially many advantages can be achieved when the platforms are constructed over the water since the free land area is very expensive especially in the vicinity of big cities.
Especially according to the invention the state of the on container or even the overall system comprising plurality of containers can be controlled and thereby preventing for example distortions or misalignments due to unbalanced loadings, winding or rough sea or weather conditions.
Next the invention will be described in greater detail with reference to exemplary embodiments in accordance with the accompanying drawings, in which:
The valve or vent 103, 103a, 103b may be controllable so that it can be opened or closed for example to deflate the airbag 101a-101f. Also the pump or the like can be used for providing filling medium into the intra-container water-displacing volume 101a-101f, such as air into the airbag via said valve or vent 103, 103a, 103b and thereby providing the floating container. When deflating the bag and thereby allowing water flow into the container, the buoyancy is decreased and the container is sink more; and conversely, when inflating the bag and thereby displacing water out of the container the buoyancy is increased and draft decreases (lifting the container higher in the water).
By controlling the water-displacing volume of the intra-container, the buoyancy and draft of the container and thereby also the same of the pontoon platform arrangement can be controlled. The float arrangements 101a-101f, like the bags, as well as also the containers and the valves, vents and pumps may have own IDs, whereupon the controlling system can provide controlling signal to an appropriate means, such as a pump or valve connected with a certain container in order to manipulate the state of that particular container. Advantageously the controlling system can determine location and type of the particular means based on said ID for example via help of database system, where the ID can be coupled with said other more detailed information, such as type and location of the means.
According to an embodiment the container 100 may also comprise the vent 103a via which the water can freely flow into/out of the container, whereupon the stabilizing container 202 can be achieved. The container 100 may also comprise the valve 103b for controlling the flow of the water into/out of the container 100. Still according to an embodiment the pump 104 may be configured to pump water into the container e.g. in order to decrease buoyancy or to pump water out of the container 100 (or at least portion of the container) in order to increase buoyancy. Still according to an embodiment the operation of the vent 103a, valve 103b and the pump 104 of the each container can be controlled advantageously independently of each other by the controlling system.
According to an embodiment the connecting means 204 is as an elongated member, the first point of which is supported at the bottom 203 of the water by anchoring means, such as the external anchor or a concrete spacer block, or anchoring container 201. In addition the second point of the elongated member is coupled with the platform structure, such as a container 100. The anchoring system is according to an embodiment of the invention the active anchoring system additionally comprising actuating means 302, 307 configured to change the distance of at least one end of the container 100 of the platform from the bottom 203 or the water surface 205 by actuating said elongated member 204. The elongated member 204 may be a wire, chain or rope (as in
It is to be noted that the pontoon platform 200 may rest to the bottom 203 directly and fixedly via its one end (for example using anchoring containers) whereupon the other end of the container is supported to the bottom via the controllable supporting means 204 (as is described in
The stabilizing container 202 may be provided with at least one vent at a specific height of the container wall, which may be a vent the opening of which can be controllable by the controlling system. As an example the container 202 space above said vent may be made airtight in such a way that, when water is let in through said vent and the container space above the vent is left with an air lock preventing the container from being completely filled with water, which allows an exemplary passive stabilization. The stabilizing container 202 may also be filled completely with water and coupled in a fixed manner with the floating containers 100 in order to increase the mass and thereby inertia of the floating system 200 and thereby more effectively suppressing any possible motions or oscillation for example due to waves of the water 205. In addition water flowing freely into and from the container via the vent damps and thereby stabilizes the motions of the container 202.
According to an embodiment the stabilizing containers 202 may also comprise the intra-container water-displacing volume 101a-101f, which volume can be controlled by the controlling system as described elsewhere in this document, and thereby the buoyancy and thereby the pontoon platform draft are adapted for being regulated by changing the gas bag capacity.
The controlling system 206 of the invention may receive for example weather forecast information from weather stations or wind direction and speed information from a windspeed meter 305 or other position information e.g. from GPS device or the like, based on which the controlling system 206 is configured to provide control signal to the controllable motor 302 for varying the length of the supporting means 204 in order to remain or change the state of the container or the platform. It is to be noted that the controllable motor 302 may be situated on the container 101 as is described, but also at the bottom or somewhere in connection with the supporting means 204 so that it is able to operate said supporting means 204.
According to an embodiment the pontoon platform 200 or a container 100 may be anchored only from one point (
According to an exemplary embodiment the pontoon platform 200 may be moved along the water e.g. by displacing water from the containers 100 (
As an example the gauges utilized may provide information representing that the most right portion tends to bend upwardly (e.g. due to waves or tidewater or whatever reason), based on which the controlling system 206 may compare the received information (e.g. stress information or high information) to state information set beforehand and based on this provide control signals to the state changing equipment, such as controllable float arrangements 101a-101f in order to remain or change the state towards the desired one. For example in the situation in question in this example, the controlling system 206 may provide control signals to the container(s) located at the first portion 200d of the pontoon platform 200 to increase buoyant force or control signals to the container(s) located at the second portion 200e of the pontoon platform 200 to decrease buoyant force. The manipulating of buoyant force can be achieved as is described elsewhere in this document.
Advantageously the controllable float arrangements 101a-101f, such as inflatable bags, can be operated separately and independently of each other so that the bags located at the first end of the container or the pontoon platform can be filled differently than the bags located at the second end of the container, whereupon the buoyancy or draft of the container at the first end differs from the same at the second end thereby allowing a tilting or inclination function of the container. The systems then advantageously comprises in addition to plurality of bags also a pump or the like and/or a controlled valve for supplying gas at least into one of the bags or for delivering water into/out of the container and for thereby adjusting the tilt, alignment, angle of bank or displacement of the container by means of different buoyancies in different parts of the container, as is described in elsewhere in this document.
As can be seen in
In addition the pontoon platform arrangement 1000 may also comprise according to an embodiment a utility work machine platform, a drilling derrick, a bridge building site, a temporary structure, a pontoon bridge and/or a bridge support structure. It is to be understood that these are only examples and the inventive concept can also be utilized in other pontoon platform arrangements 1000.
In addition it is to understood that the floating pontoon platform arrangement 1000 may comprise any of the pontoon platforms 200 with any auxiliary devices and especially the controlling system 206 for controlling the state of the floating arrangement described in this document to e.g. to provide the basis for the pontoon platform arrangement 1000 or maintain or change or otherwise control the state of the container 100, floating pontoon platform arrangement 200, 1000.
The invention has been explained above with reference to the aforementioned embodiments, and several advantages of the invention have been demonstrated. It is clear that the invention is not only restricted to these embodiments, but comprises all possible embodiments within the spirit and scope of the inventive thought and the following patent claims. For example, even if the gas bags or airbags are demonstrated in connection with many embodiments in this document as an example of the float arrangement for manipulating the state of the container and floating arrangement, it is clear that they are only examples of the float arrangement and intra-container water-displacing volumes utilized in the containers in order to provide controllable floating containers, and also other types of means utilized in the float arrangement can be used, such as controllable valves, vent, motors, propellers, turbines, supporting means or the like. In addition also other types of intra-container water-displacing volumes can be used with these embodiments, as is described in this document, such as foaming means for at least partially filling an intra-container volume or container with water-displacing foam, for example a chemical agent reacting with water or other water-displacing medium, such as ping-pong ball, or combination of these.
In addition it is to be noted that the controlling system may be operated by an operator via a user interface, such as using joystick(s) or other known UI devices. Moreover the controlling system may be operated by either on the board (floating arrangement) or externally. In addition the controlling system may function independently and based on the information gathered by it. Anyway, the controlling system may receive at least portion of the information used for providing the control signal from the gauges and meters being connected to the floating arrangement, such as from a pressure gauge located at the airbag or distance or stress gauge located at the container, but also it may also receive at least portion of that information from an external sources, such as from a control center, satellite, ships, base stations or the like, or combination of these above mentioned.
Furthermore the floating arrangement or container described above may comprise also other auxiliary or management means, such as anti-corrosion arrangement associated with the containers for preventing corrosion of the containers (electric arrangement, noble/base metal pair and/or by a special coating) even if they are not mentioned in greater details in the description.
