Description

Technical Field

[0001] This invention relates to a marine slide for evacuating from ships to floating devices, the slide being constructed to descend substantially vertically. The invention also relates to a marine evacuation system and a method for assembling the marine slide. Background Technology

[0002] Various solutions have been proposed in the past for evacuating personnel from ships and oil drilling platforms using essentially vertical descent slipways. The applicant has brought to market marine evacuation systems configured for evacuation, where the descent is largely vertical. Such systems include slipways with a series of interconnected, rigid, and spaced steel rings connected by elastic ropes attached to the rings. The elastic ropes and rings are arranged to allow longitudinal extension and contraction. The slipway also has a stocking-like elastic device arranged and held within the series of rings. The stocking-like device is adapted to slow the descent speed of falling personnel being evacuated through the stocking-like device. When using the slipway, each elastic rope extends vertically from the top to the bottom of the slipway, is launched from a high evacuation position, and can extend freely downwards. The long elastic ropes are attached to each ring using brackets and extend in parallel vertical directions, each parallel to the longitudinal axis of the slipway. Typically, the lower end of the slipway is anchored to a floating platform or life raft. Thanks to the elastic ropes, the slide can extend and retract to compensate for changes in height caused by waves. This allows people to escape via the slide even if its length changes.

[0003] Because existing slipway systems for maritime evacuation involve complex designs to meet requirements such as varying heights and safety, they are difficult to manufacture and subsequently repair and maintain. Therefore, there is a need to design simpler maritime slipways without compromising safety requirements. Summary of the Invention

[0004] One object of the present invention is to overcome, in whole or in part, the aforementioned disadvantages and defects of the prior art. More specifically, one object is to provide an improved marine slipway with a design that facilitates assembly, disassembly, repair, and maintenance.

[0005] The foregoing objectives, together with many other objectives, advantages and features that will become apparent from the following description, are achieved by means of a solution according to the invention utilizing a sea slide for maritime evacuation from a vessel to a floating device, the sea slide being configured for a substantially vertical descent, comprising:

[0006] Entrance section,

[0007] Multiple first segments AB, each first segment AB including a first upper AB end and a second lower AB end.

[0008] Multiple second-segment BAs, each second-segment BA including a first upper BA end and a second lower BA end.

[0009] Each of the first upper AB ends includes a first connecting device, and each of the second lower AB ends includes a second connecting device.

[0010] Each first upper BA terminal includes a third connecting device and each second lower BA terminal includes a fourth connecting device.

[0011] The first connecting device is configured to be opposite to and interact with the fourth connecting device to provide a first releasable connection, and the second connecting device is configured to be opposite to the third connecting device to and interact with the third connecting device to provide a second releasable connection.

[0012] These sections define evacuation routes when connected to guide personnel down the sea slide during descent.

[0013] Furthermore, multiple first segments AB can be different from multiple second segments BA.

[0014] Furthermore, the first connecting device may be different from the second connecting device, so that the first segment AB cannot be connected to another first segment AB.

[0015] Moreover, the third connecting device can be different from the fourth connecting device, so that the second segment BA cannot be connected to another second segment BA.

[0016] In addition, the first connecting device may be different from the third connecting device, and the second connecting device may be different from the fourth connecting device, such that the first connecting device interacts only with the fourth connecting device, and the second connecting device interacts only with the third connecting device.

[0017] Furthermore, each first upper AB end may include a first mark and each second lower AB end may include a second mark.

[0018] Each first upper BA end can include a third marker, and each second lower BA end can include a fourth marker.

[0019] The first mark can be configured to be arranged opposite to the fourth mark to ensure that the first upper AB end is correctly positioned relative to the second lower BA end before the first connecting device is connected to the fourth connecting device, and

[0020] The second mark can be configured to be positioned opposite the third mark to ensure that the first lower AB end is correctly positioned relative to the second upper BA end before the second connecting device is connected to the third connecting device.

[0021] The first and second markers can be different to avoid unintentionally attempting to connect the two first segments AB.

[0022] The third and fourth markers can be different to avoid unintentionally attempting to connect the two second-segment BAs.

[0023] Furthermore, the first segment AB and the second segment BA can be approximately circular.

[0024] Furthermore, the first segment AB can have a first perimeter and the second segment BA can have a second perimeter. The first perimeter and the second perimeter are approximately the same.

[0025] In addition, each connecting device can extend around the outer periphery of the first segment AB and the second segment BA, respectively.

[0026] According to the present invention, two adjacent connecting devices can be configured to interact with each other after being positioned relative to each other.

[0027] In addition, each connecting device may include multiple channel segments, each channel segment being arranged at a distance from adjacent channel segments to provide space between them, wherein a channel segment of another connecting device is configured to be inserted into the space such that all channel segments of two adjacent connecting devices together define a continuously extending channel in which locking members for locking the two adjacent connecting devices to each other are arranged.

[0028] Furthermore, the channel segments of two adjacent connecting devices can be arranged such that they can be inserted relative to each other only when the two adjacent segments are aligned with each other.

[0029] In addition, the distance between the passage sections can vary along the perimeter of each section.

[0030] The passage section may have a section extension that extends along the periphery of each section, and the section extension may vary along the periphery of each section.

[0031] Alternatively, the locking member may be circular, with the size of the circle being approximately the same as the outer perimeter.

[0032] Furthermore, the locking member may include two or more ring components, each end of which includes a locking mechanism, such that two ring components can be locked to each other, thereby providing a continuously extending ring.

[0033] Alternatively, the locking mechanism can be an opening and a bolt arranged in the opening.

[0034] Advantageously, the locking member can be made of metal, composite material, reinforced glass fiber or carbon fiber, or a combination thereof.

[0035] When viewed in a cross-sectional view, the locking member or ring component can be flat.

[0036] In addition, the connecting device can be a ring extending along the outer periphery of the first segment AB and the second segment BA, respectively.

[0037] Furthermore, each annular connecting device may have one or more openings.

[0038] Furthermore, two adjacent annular connecting devices can be positioned such that one or more openings are arranged opposite each other, thereby allowing one or more locking mechanisms to extend through the openings and lock the two adjacent annular connecting devices together.

[0039] In one embodiment of the invention, the evacuation path may be a spiral chute that extends continuously downward through these sections.

[0040] In addition, each first segment AB may have a first spiral groove component and each second segment BA may have a second spiral groove component.

[0041] In addition, the first spiral groove component may have a first spiral component end and a second spiral component end, and the second spiral groove component may have a third spiral component end and a fourth spiral component end.

[0042] Furthermore, the end of the first helical component can be configured to connect to the end of the fourth helical component and the end of the second helical component can be configured to connect to the end of the third helical component, or vice versa, to provide a continuously extending helical groove extending downward through each segment.

[0043] The spiral groove component can be connected by a zipper.

[0044] In one embodiment, the first spiral groove component may overlap with the second spiral groove component, or vice versa, to obtain a smooth sliding path.

[0045] Each slide component can be a double-layer configuration.

[0046] In addition, the slide may have a central axis, with a first center line arranged to extend downward through the slide along the central axis.

[0047] Furthermore, the second centerline can be arranged along the first centerline for redundancy.

[0048] Advantageously, each section can have an outer liner. The outer liner may include a closable opening extending along the section. The closable opening can be closed by means of a zipper.

[0049] The spiral component can be connected to the inside of the outer liner.

[0050] In addition, the diameter of the slide can be between 1 and 2 meters, and the height of each section can be between 1 and 1.75 meters.

[0051] In addition, multiple outer lines can be arranged around the circumference / periphery of these sections on the outside of the outer liner, the outer lines extending along the extension direction of the slide on the outside of the slide, and each outer line is connected to the locking member.

[0052] In addition, multiple elastic lines can be arranged around the circumference / periphery of these sections on the outside of the outer liner, the elastic lines extending along the extension length of the slide on the outside of the slide, and each elastic line is connected to the locking member.

[0053] The present invention also relates to a marine evacuation system comprising vessels or marine facilities, marine slides as described above, and inflatable life rafts or inflatable lifeboats or lifeboats.

[0054] In addition, the marine evacuation system may include a slide distributor arranged on a vessel or marine facility, the slide distributor being configured to store slides during storage and distribute slides during evacuation.

[0055] The present invention also relates to a method for assembling a marine slipway as described above, comprising:

[0056] -Provide an entry section,

[0058] Connect the first upper AB end to the entry section.

[0059] - Provides a second segment BA including a first upper BA end and a second lower BA end.

[0078] Figure 1 A sea slide 1 for evacuating people from a vessel to a floating device is shown. The sea slide 1 is constructed to descend substantially vertically and includes an entrance section 2. The entrance section 2 ensures that people to be evacuated are properly guided into the sea slide 1.

[0079] The sea slide 1 includes: multiple first sections AB, each first section AB including a first upper AB end 3 and a second lower AB end 4; and multiple second sections BA, each second section BA including a first upper BA end 5 and a second lower BA end 6.

[0080] According to the concept of the invention, each first upper AB terminal 3 includes a first connecting device 7 and each second lower AB terminal 4 includes a second connecting device 8, each first upper BA terminal 5 includes a third connecting device 9 and each second lower BA terminal 6 includes a fourth connecting device 10. The first connecting device 7 is configured to be arranged opposite to the fourth connecting device 10 and to interact with it to provide a first releasable connection 11, and the second connecting device 8 is configured to be arranged opposite to the third connecting device 9 and to interact with it to provide a second releasable connection 12.

[0081] The marine slipway 1 according to the present invention comprises three distinct sections: an entrance section 2, a first section AB, and a second section BA. Only one entrance section 2 is provided, and multiple first sections AB and multiple second sections BA are provided according to the intended height of the marine slipway. According to the present invention, the first sections AB and the second sections BA are arranged alternately. Furthermore, the first sections AB and the second sections BA are different.

[0082] Furthermore, the first connecting device differs from the second connecting device in that the first segment AB cannot be connected to another first segment AB without losing its function. The same applies to the third and fourth connecting devices, ensuring that the two second segments BA cannot be connected.

[0083] Furthermore, the first connecting device may be different from the third connecting device, and the second connecting device may be different from the fourth connecting device, such that the first connecting device can only interact with the fourth connecting device, and the second connecting device can only interact with the third connecting device.

[0084] This resulted in a fault-proof design for the sea slipway, ensuring that no errors occur during its assembly. Furthermore, it resulted in a sea slipway that is easy to assemble and disassemble, facilitating maintenance and allowing for section replacement without disrupting the rest of the slipway.

[0085] The entrance section 2 also includes a connecting device in an entrance end (not shown). The connecting device is configured to be arranged opposite to the first connecting device 7 of the first section AB in the same manner as described above and can interact with the first connecting device 7.

[0086] Sections 2, AB, and BA define an evacuation path 13 when connected to guide personnel downward through the sea slide 1 during descent. The evacuation path 13 can have various designs; however, in this embodiment, the evacuation path 13 is a spiral chute 13 that extends continuously downward through sections 2, AB, and BA.

[0087] In this embodiment, each first segment AB has a first helical groove component 14 and each second segment BA has a second helical groove component 15. The first helical groove component 14 has a first helical component end and a second helical component end, and the second helical groove component has a third helical component end and a fourth helical component end. The first helical component end is configured to connect to the fourth helical component end and the second helical component end is configured to connect to the third helical component end, or vice versa, to provide, for example Figure 1 The spiral groove 13 extends downward through sections 2, AB, and BA.

[0088] In one embodiment, the spiral groove components 14, 15 are connected by means of a zipper or similar device, thereby ensuring easy assembly and disassembly.

[0089] Furthermore, the first spiral chute component 14 overlaps with the second spiral chute component 15, or vice versa, thereby obtaining a smooth slide path and ensuring that a person sliding on the spiral chute will not be stuck by any protruding parts or elements during descent.

[0090] In addition, each slide component 14, 15 can have a double-layer configuration.

[0091] The sea slipway 1 has a central axis 16, and a first centerline 17 extends downward along the central axis 16 through the sea slipway 1. Additionally, a second centerline may be arranged along the first centerline for redundancy. The first and second centerlines may be webbing, ropes, or the like.

[0092] The first section AB and the second section BA can be approximately circular. Furthermore, the sea slide can have a diameter d between 1 and 2 meters, and each section can have a section height h between 1 and 1.75 meters.

[0093] exist Figure 2 The image partially shows the double sea slide 1 as seen from the outside. "Double" refers to the two sea slides arranged adjacent to each other. In other embodiments, multiple sea slides may be arranged adjacent to each other depending on the capacity of the evacuation system.

[0094] In the same manner as described above, the marine slipway 1 includes a plurality of first sections AB and a plurality of second sections BA that are connected to each other by releasable connectors 11 and 12.

[0095] Connectors 11 and 12 will be joined below. Figures 3 to 6 Further description. For example... Figure 2As shown, the marine slipway 1 has multiple annular members 19 arranged along the extension direction of the marine slipway 1 and spaced at predetermined intervals. Some of these annular members 19 serve as locking members between two adjacent connecting devices, as will be further described below; however, other annular members may be arranged between the ends of the first or second section to provide stability and stiffness to the marine slipway 1. The annular members 19 ensure that the marine slipway does not collapse inward when a load is applied along the slipway path.

[0096] These annular components are arranged on the outside of the outer liner 18 of each section AB and BA.

[0097] In this embodiment, the evacuation path is a spiral chute 13. As described above, the spiral chute includes multiple spiral components. Each spiral component is connected to the inner surface of the outer liner 18 on one side. The spiral component can be sewn to the inner surface along its entire length, or it can be attached to the inner surface at a predetermined location.

[0098] On opposite sides of the helical components, these components are not directly connected along the central axis, allowing them to suspend vertically. The helical components are connected at the top. The vertical extension of the helical components is then stretched through the connection between the opposite sides of the helical components and the inner surface of the outer liner. As the helical components rotate, the vertical extension is held in place at the central axis, thus creating a slide path on which evacuees can slide during descent via the sea slide.

[0099] Therefore, if the height between the vessel and the life raft or lifeboat is less than the length of the sea slide, some sections will overlap at the life raft location. The distance between the side of the helical component connected to the inner surface of the liner and the side of the helical component at the central axis will be smaller, thus preventing stretching of the vertical extension length. Consequently, the side of the helical component at the central axis will hang down as a curtain along the inner surface of the liner, allowing personnel descending the sea slide to exit at that location via the sea slide's exit. Thus, with this configuration, the sea slide's exit can be located anywhere on the sea slide, regardless of the varying extension length during evacuation.

[0100] Furthermore, multiple outer lines 20 are arranged around the circumference / periphery of the section outside the outer liner 18. The outer lines 20 extend along the extension direction of the sea slide 1 outside the slide 1, and each outer line is connected to the annular member 19. The outer lines 20 ensure that the load applied to the sea slide 1 is transferred from the annular member 19 to the outer lines 20, rather than being absorbed by the outer liner 18.

[0101] Furthermore, multiple elastic lines 21 are arranged around the circumference / outer periphery of the section on the outside of the outer liner 18. The elastic lines 21 extend along the extension direction of the sea slide 1 on the outside of the sea slide 1, and each elastic line 21 is connected to an annular member. The elastic lines 21 provide flexibility in the height of the sea slide 1.

[0102] As described above, the sea slide 1 is approximately circular. Each connecting device can extend around the outer periphery of the first segment AB and the second segment BA, respectively.

[0103] In such Figure 3 and Figure 4 In one embodiment of the invention shown, two adjacent connecting devices 8, 9 are configured to interact with each other after being positioned relative to each other.

[0104] In this embodiment, each connecting device 8, 9 includes a plurality of channel segments 22, each channel segment 22 being arranged at a distance from adjacent channel segments to provide space between them, wherein a channel segment of another connecting device is configured to be inserted into said space such that all channel segments of the two adjacent connecting devices together define a continuously extending pipe 23, wherein locking member 24 is arranged for locking the two adjacent connecting devices 8, 9 to each other.

[0105] According to the invention, the channel segments 22 of two adjacent connecting devices are arranged such that they can only be inserted relative to each other when the two adjacent segments are aligned relative to each other.

[0106] Moreover, the distance between the channel sections can vary along the circumference of each section.

[0107] The passage section may have a section extension that extends circumferentially along each section, and the section extension may vary along the circumference of each section.

[0108] The locking member 24 is circular, and the size of the circle is approximately the same as the outer perimeter. The locking member 24 may have a coupling... Figure 2 The ring-shaped part 19 described has the same configuration.

[0109] The locking member 24 may include two or more ring members, each end of which includes a locking mechanism, allowing two ring members to lock into each other, thereby providing a continuously extending ring. In a preferred embodiment, the locking member includes three ring members, which facilitates the conveying of the ring members through the channel section.

[0110] exist Figure 5 In this configuration, the locking mechanism 25 consists of an opening and a bolt arranged within it. Furthermore, the locking member 24 and the annular member 19 can be made of metal, composite materials, reinforced glass fiber, or carbon fiber, or a combination thereof. When in situations such as... Figure 5When viewed in the cross-sectional view shown, the locking member and the ring member can be flat.

[0111] Furthermore, each first upper AB end may include a first mark and each second lower AB end may include a second mark.

[0112] Each first upper BA end can include a third marker, and each second lower BA end can include a fourth marker.

[0113] The first mark is configured to be arranged opposite to the fourth mark to ensure that the first upper AB end is correctly positioned relative to the second lower BA end before the first connecting device is connected to the fourth connecting device, and

[0114] The second mark is configured to be arranged opposite to the third mark to ensure that the first lower AB end is correctly positioned relative to the second upper BA end before the second connecting device is connected to the third connecting device.

[0115] exist Figure 5 In the diagram, 26 are shown arranged opposite each other.

[0116] exist Figure 6 The diagram shows a releasable connector 12. The connecting device 8 includes multiple channel segments 22, each arranged at a distance from its adjacent channel segments to provide space between them. A channel segment 22 of another connecting device 9 is configured to be inserted into this space, such that all channel segments of the two adjacent connecting devices together define a continuously extending conduit, wherein locking members (not shown) are arranged for locking the two adjacent connecting devices 8, 9 together. Figure 6 As shown, the channel segments 22 of two adjacent connecting devices 8 and 9 are arranged such that they can only be inserted relative to each other when the two adjacent segments are aligned with each other. As described above, markings are arranged to facilitate the alignment of the two opposing connecting devices relative to each other. Figure 6 In this assembly, connecting device 8 has several markings 26 described as B1, and connecting device 9 has several markings 26 described as B2. When connecting device 8 and connecting device 9 are assembled together, B1 and B2 are aligned, thereby ensuring that the channel segments 22 of each connecting device can together define a continuous pipe. (As shown in...) Figure 6 As can be seen, if B1 and B2 are not arranged opposite each other, the different channel sections will be offset relative to each other and thus no pipe will be provided.

[0117] exist Figure 3 In this embodiment, the outer liner 18 includes a closable opening 27 extending along the section. The closable opening 27 can be closed by means of a zipper 28. Each section AB, BA has a closable opening 27 arranged in the outer liner 18.

[0118] Furthermore, the slipway distributor 50 can be arranged on a vessel or offshore facility, and the slipway distributor 50 is configured to accommodate offshore slipways during storage and to distribute offshore slipways during evacuation. Figures 7 to 11 An embodiment of the slide distributor 50 is shown in the figure.

[0119] The slide distributor 50 includes a frame 51 to be mounted on a vessel or offshore facility. The frame 51 includes a first chamber 52 and a second chamber 53. The offshore slide (not shown) is positioned in the second chamber 53 during storage. The first chamber includes a plurality of pivot points 54. These pivot points are configured to guide an elastic line (not shown). The elastic line functions to hold the offshore slide in place and under appropriate tension, unaffected by changes in height between the slide distributor and the water surface due to the vessel's movement in the ocean and / or wave height. The first chamber also has an entrance 55 for use by personnel awaiting evacuation. Additionally, a guide 56 is provided at the entrance 55 to assist personnel awaiting evacuation into the offshore slide.

[0120] like Figure 8 As shown, the sea slide is connected at one end to the bottom frame 57. The bottom frame 57 is also connected to an inflatable life raft (not shown) and is configured to assist in the deployment of the inflatable life raft and the sea slide.

[0121] exist Figure 9 A portion of frame 51 is shown in the diagram. Multiple mounting members 58 are arranged to connect to frame 51. An outer line (not shown) is configured to be mounted in the mounting members 58, such that the offshore slipway is securely fastened to the frame. Additionally, a flat profile 59 is arranged at the top of frame 51. The flat profile is configured to retain the liner relative to the frame by introducing an outer liner between frame 51 and the flat profile 59, and subsequently fastening the flat profile 59 to frame 51.

[0122] Figure 10 The slide distributor 50 is shown in its storage position, while... Figure 11 In the middle, the slipway distributor 50 moves to the evacuation position where the sea slipway is ready to be deployed. Figure 10 In the middle, the slipway distributor 50 is suitable for being located within the outer perimeter of the vessel or offshore facility, while Figure 11 In the middle, the slide distributor 50 has been moved to a position outside the outer perimeter, so that the sea slide can be deployed in a generally vertical direction.

[0123] In this embodiment, a slide distributor 50 is shown. Depending on the expected capacity of the marine evacuation system, multiple slide distributors may be arranged adjacent to each other.

[0124] exist Figure 12The image shows a marine evacuation system according to the present invention. The marine evacuation system includes a vessel 101 or marine facility, a marine slide 1 as described above, and an inflatable life raft 102 or an inflatable lifeboat or rescue boat.

[0125] The present invention also relates to a method for assembling a marine slipway 1, the method comprising:

[0126] -Provide an entry section,

[0127] - Provides a first segment AB including a first upper AB end and a second lower AB end.

[0138] Repeat the steps of providing additional first sections AB and second sections BA, aligning the connecting devices of these sections, and connecting the connecting devices to each other until the predetermined height of the sea slide is reached.

[0139] Alternatively, the alignment step can be performed by arranging the markers relative to each other.
