Definitions
- the invention concerns a method and a device for securing closed decks with cargo on ships respectively, e.g. decks for vehicles or cargo in holds by which in the ceiling of the deck or the cargo hold, preferably in the ship's longitudinal direction, there are suspended extendable, gas-fillable elastic bags.
- a load stabilizing system for loads in containers with a defined volume.
- the load is stabilized by positioning one or more bags between a wall of the container and a load and/or between two load items.
- the inflated bags will exert a pressure to the load and thus provide a fixing or securing thereof.
- JP-A-52 135 187 it is described a system for locking cars on a lower deck of a carry ship, by which a bag provided under the deck ceiling is inflated and thereby will urge the cars downward and thereby holding them firmly.
- a cargo hold or deck which is open during loading and unloading can, after the cargo has been placed in position, be divided up in a very simple fashion into smaller units, while at the same time the cargo is secured in a simple and reliable manner.
- the open space on the deck or in the hold is also filled, a minimum of space thereby being available for penetration of water in the event of an accident and in addition to the fact that the amount is reduced, this water will have only limited capability of movement, thereby substantially improving the security of the ship.
- the inflated bags according to the invention will give the ship an extra buoyancy in the event of an accident, thus enabling the ship to be kept afloat longer than normal in an emergency situation and even possibly preventing it from sinking.
- the opportunities for summoning help will therefore be much greater.
- the filled gas bags can also be filled with a fire-retardant gas, thus automatically extinguishing any small fires which may break out.
- a further advantage which is obtained by means of the invention is that the cargo is automatically secured without the necessity of employing traditional securing equipment such as chains and straps. This means a substantial rationalization in connection with loading and unloading, while at the same time the cargo is carefully secured with an evenly distributed securing effect over the entire surface of the cargo.
- the cargo can be automatically tightened up during transport by adjusting the securing pressure.
- the cargo securing can also be constantly monitored by means of sensors.
- a further advantage which is obtained by means of the invention is that in cases where the hold or deck is not full, the vehicles or the cargo can be located in the most favourable positions on the ship, since by inflating the bags the cargo can be secured and kept in the desired position on the cargo surface.
- the device according to the invention can be built into existing ships and car ferries without the need for comprehensive mechanical conversions which alter the vessel's mechanical characteristics.
- the device is very easy to use. and will it not lead to a reduction in the capacity on board the ship.
- By placing the bags in a grid pattern the space can be divided and securing can be obtained against the outer edges of the ship, e.g. against the vehicle doors at the ends of the ship, which provides an additional security.
- the attachment means in the deck's driving plate can be advantageously located in such a manner that they establish driving lanes for the vehicles on a car deck and thereby also facilitate the correct positioning of the vehicles.
- Fig. 1 of the drawing illustrates a car deck on a ship or ferry 1, where the deck is denoted by 2.
- vehicles or cars which are denoted by 3 are lined up behind one another in the conventional manner.
- extendable, gas-filled, highly elastic bags which are suspended in the areas which are denoted by 4.
- corresponding elastic bags can also be provided athwartships, e.g. in the locations denoted by 5.
- Fig. 2 illustrates a section through such a car deck with the device according to the invention in a secured state.
- Figs. 3 and 4 illustrate purely schematically the positioning of the elastic bags between the vehicles on the deck.
- the bags 4 are illustrated here in an extended position, where they are fastened by means of attachment means 7 to the floor of the deck between the vehicles. In this position a longitudinal sectional division of the car deck has been achieved, which will prevent any water which has penetrated into the ship from washing back and forward between the ship's transverse sides.
- Fig. 4 illustrates the device according to the invention in the securing position, the elastic bags being inflated and thereby securing the cargo, i.e. the vehicles and also filling the space between the vehicles above and at the side.
- This fil- ling operation is performed in the lateral direction of the vehicles, thus hold- ing them securely against one another, but as the expansion of the bags proceeds the vehicle will also be secured from the top and thereby be held secure in a cushioned fashion. Only the space 8 under the vehicles will be free.
- Figs. 5 and 6 illustrate the suspension and the attachment of the bags 4.
- the bags act as a kind of curtain.
- Their lower edge is designed with a weight load or beam arrangement 9 which holds the bag taut like a curtain in the longitudinal direction, in the example shown pulled down in such a manner that the beam 9 is located in a recess 13 in the floor of the deck.
- This is not an absolute requirement, since the beam can also be made to abut against the actual deck floor 6.
- On each side of this area 13 there are provided rotatable plate elements with rounded ends which can be rotated towards each other by means of suitable drive means and thereby grip the curtains or the top of the beam 9 and hold it in place.
- a curtain or wall secured above and below between each row of cars, which will prevent movement, e.g. of water in the ship's transverse direction.
- the mechanism for rolling up the bag or the curtain 4 is illustrated in fig. 6.
- a bracket 10 In the ceiling of the deck or the cargo hold, e.g., there is attached with a bracket 10 a rotatable roller 11, which is motor-driven, thus enabling the curtain 4 to be rolled up or pulled down according to the direction of rotation.
- the beam 9 When it is rolled down the beam 9 will ensure additional traction in a downward direction.
- the roller 11 can be designed with one or more rows of holes or slots 12, as illustrated in the lower part of fig. 6 and also in fig. 5.
- the ends of the roller are thereby sealed and it is in communication with an air intake from a compressor or another air source which can blow in air which fills the bags through holes 12, causing the bags to expand and envelop the vehicles as illustrated in fig. 4.
- air intake from a compressor or another air source which can blow in air which fills the bags through holes 12, causing the bags to expand and envelop the vehicles as illustrated in fig. 4.
- air is extracted through the same system, causing the bags to contract into the form of curtains, whereupon they can be rolled up.
- the mode of operation of the invention can be said to be as follows:
- the invention provides a very flexible solution, since the system can be built into existing ferries without comprehensive mechanical conversion which could result in a change in the vessel's mechanical characteristics.
- the securing method is also extremely flexible and can also be employed in the case of only partially filled decks, since, at any rate in rough weather, the remaining empty spaces can be completely filled by means of the air bags.
- Many modifications will be possible within the scope of the invention.
- it will be possible to monitor the system by means of sensors, and pressure regulators which will ensure that the situation on the vehicle deck remains constant.
Description
