Definitions

• the present invention relates to a watercraft, such as. B. a passenger ship, a ferry, a dangerous cargo ship or the like. , with a deck and with a buoyancy space in the deck, the buoyancy space containing air in a first operating state.
• buoyancy spaces In normal operation, a first operating state of such ships, the buoyancy spaces have been calculated in accordance with a necessary buoyancy volume and filled with ambient air.
• the buoyancy rooms do not have to be limited to their buoyancy function, but generally have very diverse functions. Any cavity defined on the ship can serve as the buoyancy space, be it a cabin, a bunker, a load or a type of chamber.
• buoyancy rooms with other functions also contain features that serve to fulfill these other functions.
• the object of the present invention is therefore to create a watercraft of the type mentioned at the outset, in which the buoyancy can be stabilized immediately when loss of buoyancy occurs.
• the object is achieved in that the buoyancy space is filled with a foam in a second operating state is that has a high cell volume with closed cells and a dimensionally stable aggregate state.
• buoyancy space is used in the following and in the claims in the sense that it refers to the spaces of a watercraft that serve as a stable buoyancy space in a second operating state.
• cell volume is used in the following and in the claims in the sense that a large
• Aerial absorbency is meant either by very many small cells or by very few large cells.
• buoyancy rooms By filling one or more buoyancy rooms with a dimensionally stable foam with a high cell volume, if in an emergency situation water can enter the buoyancy rooms, the corresponding buoyancy rooms cannot be flooded with water and retain the buoyancy function of the due to the buoyancy volume retained by the foam respective buoyancy space.
• buoyancy rooms are multi-functional rooms, such as. B. a cabin, is also ensured that the objects in the room are enclosed by the foam and thus protected from damage or loss.
• the buoyancy space comprises a delivery device which delivers the foam in an unstable physical state during a transition from the first operating state to the second operating state.
• a delivery device which delivers the foam in an unstable physical state during a transition from the first operating state to the second operating state.
• foams are sprayed or sprayed in a liquid state of aggregation into the buoyancy space, which solidify in ambient air and reach the stable state of aggregation in a short time.
• a control device is provided which controls the dispensing device. Controlling the dispensing device of each buoyancy space leads to the possibility of specifically selecting dispensing devices for dispensing foam per se and for dispensing a metered amount of foam in particular. This allows the buoyancy to be stabilized at various points on a ship.
• control device can be triggered manually depending on the detection of a loss of lift.
• passenger cabins can also be put into a second operating state as a buoyancy space.
• the manual release enables the passenger cabin to be inspected before the release and to ensure that there are no more people in the cabin.
• control device selects the deck with the buoyancy space depending on the location of the loss of buoyancy. This means that the buoyancy can be stabilized in a targeted, deck-specific and loss-dependent manner.
• control device selects the buoyancy space on the deck depending on the location of the loss of buoyancy. As a result, the buoyancy can also be stabilized in a targeted, space-specific and loss-dependent manner.
• each buoyancy room is selected from a group consisting of exposed cabins, common rooms, bunkers, foredeck chambers, Aft ship chambers, loads, as well as forepeak and rowing machine.
• the use of all functional rooms as buoyancy rooms enables optimal buoyancy protection in an emergency.
• Another advantage according to claim 9 is that the foam is pressure-resistant in its dimensionally stable state. As a result, the buoyancy chamber remains secured as such even when the external pressure is increased.
• the foam is a plastic foam that contains a foam stabilizer.
• Numerous plastic foams are known from the prior art which, due to the foam stabilizers, have the required characteristics, high cell volume, compressive strength and dimensional stability, so that a suitable selection is easy.
• Figure 1 is a schematic view of a passenger ship, which is designed according to the invention.

• FIG. 3 shows a schematic front view of the passenger ship with rooms
• FIG. 4 shows a schematic front view of the passenger ship from FIG. 2 with buoyancy spaces foamed according to the invention
• FIG. 5 shows a schematic illustration of a control device for the foaming of the buoyancy spaces of the passenger ship.
• a passenger ship is shown schematically as watercraft 1.
• the passenger ship is said to be in the ing embodiment have approximately 4000 NRT (net register tons) and 6000 BRT (gross register tons).
• the maximum mass to be caught is approximately 4100 GRT.
• the buoyancy volume from just two decks (passenger decks) 3 with a total of approx. 200 buoyancy rooms (cabins) 5, each with 20t buoyancy, is at least 4000t.
• the buoyancy volume from the buoyancy areas of the fore and aft ship adds up to at least 1000t. This results in a total buoyancy volume of approx. 5000t, i.e. a reserve buoyancy of at least 900t.
• decks 7 are provided above decks 3.
• the water line is designated 9 and lies on a lower region of a hull 11.
• the watercraft 1 is in a rescue position, i.e. H. in an emergency.
• the water line 9 lies in an upper area of the hull 11.
• buoyancy spaces 5 of the passenger decks are filled with a foam (shown here in black color) 13. But there are also buoyancy spaces in the foredeck 15 and aft ship 17 filled with foam.
• buoyancy spaces 5 inside the ship are shown schematically. Theoretically, all buoyancy spaces 5 shown can be filled with a foam in an emergency. In practice, however, some buoyancy spaces 5 will be selected for this purpose. These buoyancy spaces 5 are shown in FIG. 4.
• the outer cabins of all (passenger) decks 3, the foredeck 15 and, also shown here, the rowing machine in the aft ship 17 each serve as a buoyancy space 5.
• the upper decks 7 serve as escape decks.
• a control device 19 is shown schematically in FIG. 5.
• the control device 19 controls a delivery device 21 which is arranged in each of the drive rooms 5 selected for the emergency.
• the dispensing device 21 is preferably a tank mounted on the ceiling in the respective buoyancy space 5, in which the foam is stored in a form-unstable, that is to say liquid or gaseous, aggregate state.
• the ceiling installation ensures that the buoyancy space is filled cheaply and evenly.
• an emergency switch 23 is arranged, which is connected via a line 25 to a gas pressure generator 27, such as. B. a pressure conditioner is operatively connected.
• the gas pressure generator 27 is connected via a line system 29, 30 with a valve device 31, e.g. B. a solenoid valve, operatively connected to each dispensing device 21 in each buoyancy chamber 5.
• the valve device 31 is also operatively connected to a safety switch 35 via a further line 33.
• the emergency switch 23 is actuated.
• the gas pressure generator 27 generates a gas pressure in the line system 29, 30. If the selected lift rooms 5 are passenger cabins or rooms in which people can stay, the lift rooms 5 are inspected by the personnel. If the personnel determines that a buoyancy chamber 5 is empty, the safety switch 35 is actuated, as a result of which the valve device 31 opens and the gas pressure on the line 30 is transmitted to the output device 21. As a result, the foam, which is in an unstable physical state, is expelled from the dispenser 21 and sprayed or sprayed into the buoyancy chamber 5. The foam solidifies in ambient air with the properties already mentioned and ensures the buoyancy function of the corresponding buoyancy space 5.
• the control device 19 can be designed in such a way that depending on the location of a loss of buoyancy, specific decks 3 and buoyancy rooms 5 are addressed via the line system 29, 30.
• the foam can be a mineral or organic natural foam or plastic foam with or without a foam stabilizer. Foams with the properties mentioned are generally known from the prior art, so that they will not be described further here.
• the safety switch 35 When actuated, the safety switch 35 closes a circuit for triggering the valve device and at the same time opens a mains circuit for the corresponding buoyancy space.
