- hoop-and-loop fasteners or Velcro may be provided for securing the closing element at the opening of the inflatable barrier tube.
- the closing element may be made from a waterproof flexible material, such as a rubber material or an impregnated piece of cloth.
- the closing element may be detachable.
- the closing element may be adapted to be simultaneously secured to two abutting inflatable liferafts to provide a substantially planar walking path between the inflatable liferafts.
- the closing element of one inflatable liferaft may be adapted to be secured to a closing element of an abutting inflatable liferaft to provide a substantially planar walking path between the inflatable liferafts.
- the present invention further relates to an evacuation system comprising two or more inflatable liferafts according to any of the preceding claims and one or more disembarkment means for transferring persons from a vessel to at least one of the inflatable liferafts, wherein at least two of the liferafts are arranged side by side with one of their respective openings and entry zones abutting the opening and entry zones of the other inflatable liferaft.
- the present invention relates to a vessel comprising the inflatable liferaft described above.
- Fig. 1 shows an inflatable liferaft comprising four entry zones
- Fig. 2 shows a view of a section of the inflatable liferaft shown in Fig. 1,
- Figs. 3A-3C show close-ups of the construction of an entry zone
- Fig. 4 shows a vessel comprising an evacuation system in a deployed state.
- Fig. 1 shows an inflatable liferaft 1 according to an embodiment of the invention.
- the inflatable liferaft 1 is shown in an inflated conditon, and the following describtion of the structural components of the inflatable life raft will in generel adhere to the inflatable liferaft in an inflated condition.
- the inflatable liferaft also exists in a deflated condition, wherein the inflatable liferaft is packable and thus may be packed to significantly reduce its size.
- the essential structural components of an inflatable and packable liferaft are of a flexible character, allowing for the inflatable life raft to be bent and folded into a packable condition.
- the inflatable liferaft 1 comprises an inflatable floatation tube 10 defining a lower circumferential rim and an inflatable barrier tube 11 defining an upper circumferential rim.
- the inflatable barrier tube is arranged on top of the inflatable flotation tube and defines a protected area 14 for containing passengers.
- a flexible flooring element 12 is provided between the inflatable flotation tube and the inflatable barrier tube, thereby defining a bottom of the inflatable floatable unit.
- four openings 13 are provided in the upper circumferential rim at a section along a perimeter 111 of the inflatable liferaft, thereby defining four entry zones 15 providing access to the protected area, which entry zones are substantially levelled with the flooring element. It is to be understood by those skilled in the art that other numbers of openings and entry zones, both higher and lower than that specified above, are possible and are considered to be within the scope of the present invention.
- the inflatable liferaft comprises inflatable cross members 18 secured to the inflatable flotation tube, as shown in Fig. 2, and inflatable roof support members 19 in the form of inflatable arcs extending across the inflatable liferaft.
- the roof support members 19 are adapted to support a suspended roof element 20, as shown in Fig. 4.
- the opening is constituted by a bend 16 provided in the inflatable barrier tube 11.
- the bend 16 extends in a substantially vertical direction downwards towards the inflatable flotation tube.
- the bend 16 is constituted by a series of bends 162 of the inflatable barrier tube, preferably four substantially angular bends.
- a section 161 of the bend of the inflatable barrier tube is arranged in level with the inflatable floatation tube, extending along the perimeter 111 of the inflatable liferaft.
- the section 161 of the bend is thus arranged below the flooring element, and the opening provided in the upper circumferential rim hereby becomes levelled with the flooring element.
- a planar entry zone is defined, as shown in Fig. 3B.
- the entry zone thus comprises no differences in level, which greatly improves accessibility to the inflatable liferaft.
- both the inflatable flotation tube and the inflatable barrier tube may contribute to the buoyancy of the inflatable liferaft.
- a corresponding bend 17 is provided in the inflatable flotation tube.
- the bend 17 extends in a direction parallel to the extension of the flooring element, inwards towards a centre of the inflatable liferaft.
- the bend 17 thereby partly encloses the bend of the inflatable barrier tube, which may enhance the structural stability of the entry opening and entry zone.
- the bend 17 of the inflatable flotation tube is also constituted by a series of bends 172, preferably four substantially angular bends, in the inflatable flotation tube.
- the opening may be constituted by a section of the inflatable barrier tube being cut out, whereby the inflatable barrier tube comprises end sections arranged on opposite sides of the opening.
- the opposite end sections of the inflatable barrier tube may further comprise angular bends, whereby each of the end sections extends downwards into engagement with the inflatable flotation tube.
- the inflatable barrier tube may be brought into fluid communication with the inflatable flotation tube.
- the inflatable liferaft 1 may comprise four openings 13 and associated entry zones 15. The openings are provided on opposite sides of the inflatable liferaft, directly opposite each other. In another embodiment, the inflatable liferaft may alternatively comprise openings arranged differently, such as along the sides and/or in the bow and/or stern of the inflatable liferaft.
- the inflatable liferaft further comprises a closing element 21, shown in a closed position in Fig. 3C. The closing element is used for selectively opening and closing the opening 13 in the inflatable barrier tube to prevent water from entering the protected area.
- the closing element is constructed as a flap fixedly secured to the inflatable barrier tube or the inflatable flotation tube along a bottom edge 212 thereof.
- the closing element comprises zippers, hoop-and-loop fasteners or other fastening means 211 for securing sides 213 of the closing element in the closed position.
- the closing element is made from a waterproof flexible material, such as a rubber material or an impregnated piece of cloth.
- the closing element In the open position (not shown), the closing element may be adapted to secure two abutting inflatable liferafts to each other and to provide a substantially planar walking path between the entry zones of each of the inflatable liferafts.
- FIG. 4 shows a vessel 102 comprising an evacuation system in a deployed position.
- the evacuation system comprises four inflatable liferafts 1 deployed end to end and a disembarkment means 101, such as a chute or slide, for transferring persons from the vessel 102 to the inflatable liferaft next to the vessel.
- the disembarkment means may be arranged at selected positions on the vessel and be manned by trained crew to secure fast and safe evacuation of the people on board .
