Abstract

A marine escape system has a passage (13; 30, 31, 32) extending between an evacuation point on a vessel and an inflatable life raft. The passage (13; 30, 31, 32) is arranged vertically and is connected to a succession of hoops (15). The connection between at least one of the hoops (15) and the life raft is by means of flexible elongate members (24) of differing flexibility. These are held in tension so that, as the life rafts move on swell, the passage extends and retracts from the lower end first. This allows the passage (13; 30, 31, 32) to have only one exit which can be within a life raft (12) so that persons can evacuate from the ship without ever being exposed to the elements. The passage may include a helical tube (13) or a tube (30, 31, 32) with angled panels (40).

Description

Marine escape system

The present invention relates to marine escape system.

Marine escape system is used for withdrawing personnel from offshore structures when meeting accident accident.This structure can be oil derrick or ship.

A kind of form of marine escape system comprises life raft, and people can enter in it and be withdrawn.But owing to lifeboat uses on the water, and sizable diff-H (freeboard depth) is arranged usually between the place that will withdraw the crowd on the structure and lifeboat, therefore the passage of certain form need be arranged between the two.

The known available chute of being made by inflatable article makes it extend to lifeboat from extraction point.Chute can directly extend on the lifeboat or extend on the gas filed raft tectonics thing and be that lifeboat is arranged thereon.The freeboard depth of some ship can reach 14-15 rice, so chute is quite long.

Nearest shipwreck accident causes the concern that public opinion is bigger, and people emphasize need withdraw the crowd rapidly from offshore structures when meeting accident accident.Similarly be that such requirement is arranged, any ship that rides the sea must be withdrawn 400 people in 17 minutes and 40 seconds.In addition, similarly be that such requirement is arranged, any marine escape system must have under the high climatic conditions of three meters waves in strong breeze to be operated, and marine escape system must can both use in following considerable time hanging over the condition that the ship next door ride the sea.

The bevelled chute can not meet this requirement.Because need stablize so that stop sizable sideway movement under rough weather from the chute that the ship side stretches out.In addition, in order to adapt to this weather, the necessary comparatively robust of chute, the remarkable volume that increases chute of this meeting.

Marine escape system was also once proposed like this, connected with a pipe that contains spiral slide between extraction point and life raft.For example can consult WO-A-84/D2658, WO-A-94/01324 and US-A-3994366.Just in passage, slide and come out the personnel of extraction point access passage from the outlet of pipe low side along spiral path.

Tackle sideway movement under rough weather, pipe is easy to be more stable than chute.But pipe has the high problem of adaptation wave, and as mentioned above, unrestrained high energy with six meters or the freeboard depth that changes ship more.

Once be suggested in the past, in order to adapt to this situation, the pipe of being made by flexible material is had is enough to adapt to the high extreme length of wave.The extraction point of pipe from the structure hung down and with unnecessary length and is deposited on the platform, and unrestrained higher primary school during in maxim people evacuated on the platform.Because the distance between platform and extraction point can change, what can stretch out or be deposited on the platform from platform pipe.This once was disclosed in WO-A-94/01324.

The problem of An Paiing is that the mono-outlet can not be set like this.In order to address this problem, once on such pipe, be provided with a plurality ofly in the past along the isolated outlet of length, make the personnel that withdrawn can be when arriving platform from exporting out near flat-bed.But this can not be satisfactory, because personnel can come out too early or the flat-bed position can change and causes selected outlet to become suddenly to be not suitable for.

Have a passage that supplies personnel to use according to marine escape system provided by the present invention, the one end has an import and at the other end relative with said end one outlet is arranged; Between import and outlet, be provided with at least one supporting for passage, this supporting is being hung by at least one the first long and narrow elastic components, have at least one second long and narrow elastic component to extend to outlet from this supporting, this at least one the second long and narrow elastic component has bigger elasticity than at least one the first long and narrow elastic components, therefore will be than extending and shrink with the part passage between the supporting is more Zao at the part passage between outlet and the supporting in import, the extending and contraction of whole passage adapt to import and export between the change of distance.

Variation by pipe length between import and outlet just can adapt to the wave height, keeps the mono-outlet simultaneously.

According to alternative plan of the present invention, be provided with an escape chute, this chute has a general long and narrow pipe that launches in vertical direction and a series of isolated part in pipe, and these parts and pipe form a path that can supply personnel to pass through.

At first consult Fig. 1, marine escape system has lead respectively separately escape chute 11 of two Emergency Exits 10.Each escape chute terminates on separately the lifeboat 12, also has two other lifeboats 12.Should be understood that marine escape system is maintained at the interior and expansion when urgent of container of ship one side usually, its mode will illustrate below.

Consult Fig. 2,3 and 4 now, each escape chute 11 all has a spiral sealed tube 13 of being made by Foldable material (as fabric).Pipe 13 can be provided with reinforce belt 14 by spacing along its length, so that keep pipe 13 unimpeded.

Pipe 13 can be by a plurality of hoop 15 supportings that separate along its length.As shown in Figure 2, have 11 hoops 15, but also can increase and decrease with the need.Each hoop 15 is made by the alloy or the carbon fibre material of a rigidity.Representative type hoop diameter can be 2.3 meters.

Can see best that from Fig. 3 and 4 each hoop is provided with six attachment points 16, on hoop 15 periphery with the angular separation that equates apart from one another by opening.Its purpose will illustrate below.

As seen from Fig. 2,3 and 4, each hoop 15 all be positioned on pipe 13 length certain a bit on, reach maximum in both spacings of axis 18 of the axis 17 of this pipe 13 and hoop.Five flexibilities of pipe 13 usefulness but stiff long and narrow 19 and seven flexibilities and elastomeric long and narrow 20 remain on this position.Can be rope for non-resilient 19, and flexible piece 20 is made by elastomeric tartan preferably.

Non-resilient 19 is that the point of opening with equi-angularly space 21 from the peripheral part of pipe 13 extends, this part position is between two parallel planes, tube axis 17 is passed through and the axis 18 of another plane by binding round in one of them plane, all perpendicular to the hoop radius that extends between hoop axis 18 and tube's axis 17, therefore said part is pipe part to hoop axis 18 above 13 on these two planes.Like this, non-resilient 19 just is fixed up the maximum spacing between tube's axis 17 and the hoop axis 18, stops pipe 13 further close to hoop 15 thus.

Elastic component 20 also connects at pipe 13 with between binding round 15.Wherein two elastic components 20 are outward extending from last two points 22 relative on diameter of pipe 13 peripheries, and the position comprises in tube's axis 17 and the plane perpendicular to the radius that extends by tube's axis from the hoop axis at one.20 of all the other some elastic components are being opened with equi-angularly space between these two points 22 on pipe 13 peripheries.

Elastic component 20 just can allow pipe 13 to move to make the interval of tube's axis 17 and hoop axis 18 to dwindle like this.But at any time elastic component 20 all is slack-free, so they can provide power trend to make pipe 13 turn back to position shown in Figure 3, and this position can make spiral tube 13 have 30 ° helical angle.

Hoop with bind round 15 between also by two kinds of flexible materials, promptly stiff flexible piece 23 and elastomeric flexible piece 24 are interconnected.

Non-resilient 23 top-supported 25 from escape chute 11 extends downwardly into the 6th hoop 15, as shown in Figure 2.Have six flexible pieces 23 and be spaced apart from each other with isogonism, and each hoop is connected on the attachment point 16 around these hoops 14.Like this, stiff flexible piece 23 just is fixed up the maximum spacing between the first and the 6th hoop.

The 6th hoop 15 usefulness resilient flexibility parts 24 are connected on the relevant lifeboat 12.Have the resilient flexibility part 24 of three kinds of different types, they have elasticity in various degree.The first elastic component 24a is the elasticity minimum, and they extend between the 6th hoop and the 8th hoop.Have six flexible piece 24a, they are attached on the attachment point 16 of the 6th, the 7th and the 8th hoop.

The second resilient flexibility part 24b has more elasticity than the first resilient flexibility part 24a.Have six such parts, they extend between the 6th hoop the 15 and the tenth hoop 15, and are linked on the attachment point 16 of these hoops.

The 3rd resilient flexibility part is attached between the tenth hoop and the relevant lifeboat 12, and they have more elasticity than the second resilient flexibility part 24b.Have six such part 24c, they are linked on the tenth and the 11 hoop 15 the attachment point 16 and on the attachment point (not shown) on the lifeboat 12.

The diameter of the representative type first resilient flexibility part 24a can be 19mm, the extensible 4000mm that surpasses under the load of about 7.5N.The diameter of the representative type second resilient flexibility part 24b can be 16mm, the extensible 4000mm that surpasses under the load of about 5.5N.The diameter of representative type the 3rd resilient flexibility part 24c can be 12.5mm, the extensible 4000mm that surpasses under the load of 3.5N.

The available diameter in the outside of this structure general with bind round 15 identical fabric pipe (not shown) and surround.

Each outlet 10 all is connected in the supporting 25 of escape chute 11 upper ends.So just with the import of export orientation lifesaving chute 11 upper ends on the ship.

Lifeboat 12 is made of appendix 25, and is covered by fabric 27.Lifeboat is generally oblong on birds-eye view, as shown in Figure 1 and to be held together into be a rectangular matrix.The lower end of each escape chute 11 is provided with an outlet in its relevant lifeboat.

Before the use, lifeboat 12 is deflated and in lifesaving chute 11 is stored in a container that is contained in ship upper outlet 10 places.Will be appreciated that escape chute 11 few spaces of need,, can easily be crushed and manage 13 fabric because each hoop 15 can stack together when flattening.Part 23,24 also can crimp onto in the less space.

When emergency situation took place, lifeboat 12 and escape chute 11 were penetrated in container, and outlet 10 is opened.When they launch, with a pressure gas source (not shown) lifeboat 12 is inflated in a conventional manner.Lifeboat 12 is provided with the water bag (not shown), and when lifeboat 12 was run on the sea, this water bag promptly was full of by water.The length of the weight of lifeboat 12 and non-resilient 23 and elastic component 42 is selected like this, makes under the situation of the sea of calmness and the normal stand under load of ship, fully extends for non-resilient 23 and elastic component 24 is subjected to tension force.As mentioned above, representative type elastic component 24 can provide an elongation that surpasses 12000mm between them.Can arrange so in this case, the elongation that makes elastic component 24 on ash breeze is 6000mm.

The elongation of elastic component 24 can increase the 6th the hoop 15 with relevant lifeboat between distance.This can make the helical angle of pipe increase as shown in Figure 2.This can make pipe stretch again, like this pipe 13 is connected to the flexible resilient part 20 of hoop on 15 and will extends pipe 13 is moved to the axis 18 of hoop 15.

When such expansion, personnel just can enter the import of pipe 13 1 ends, slide through pipe along spiral path and appear in the lifeboat.Therefore, they outwards do not expose in the whole stroke from the ship to the lifeboat.

Wave will make lifeboat 12 with respect to outlet 11 and thereby up-and-down movement increases and reduce the freeboard depth of ship.This can be by the elongation and the shrinkage-compensating of the elongation of elastic component 24 and contraction and pipe 13.The 3rd elastic component 24c will at first extend, and next the second elastic component 24b stretches out, more next first elastic component 24a elongation.The weight that is provided by lifeboat 12 in the termination of pipe 13 enough causes this elongation and lifeboat 12 can not risen on the sea.The position of the axis 17 of pipe 13 also can change, and this change is compensated by elastic component 20.When such situation took place, the helical angle of pipe 13 also can change.

Should be understood that as above illustrated in conjunction with the accompanying drawings life saving system peculiar to vessel can have multiple variation.

Not necessarily need two escape chutes 11, can be with one or three or more escape chute.Each escape chute not necessarily needs to terminate in the lifeboat 12, and also can terminate in a system has on the showy platform of lifeboat.

A kind of as the scheme of selecting in, pipe 13 can on its length certain a bit be separated into be two parallel pipes make the personnel that withdraw from ship can be successively earlier from a pipe then under another root pipe.

Hoop with bind round between be connected and not necessarily need to finish with flexible piece 24, finish for also available any suitable extensible.

Though top illustrated scheme just can flexibly be extended and shrink at one section from the 6th hoop 15 to lifeboat 12, also can from lifeboat to not being flexibly to stretch on the whole length of other hoops 15 of the 6th hoop.

It is also understood that, make chute remain on plumbness in the weight trend of the lifeboat 12 of escape chute 11 ends.Requirement with respect to any stability of the position of ship just can reduce about escape chute 11 like this.

Evacuee's evacuation path not necessarily needs to be spiral tube, the spiral chute of an also available opened upper end, or with a pipe along its length within it the compartment of terrain arranging a series of alternately do opposing face to the plane, each plane all tilts at angle with pipe range.The personnel that enter pipe can be slided next inclined-plane earlier, and it is sliding next towards opposite inclined-plane to forward the opposite then to, hockets like this until arrive at till the tube end.In this case, the inclined-plane can be made so that adapt to the elongation and the contraction of pipe by flexible material.

Next consult Fig. 5 to 22, other alternative form of escape chute shown in Figure 1 is described now.

In the present embodiment, the escape chute is made up of three kinds of different intervals, the left hand interval shown in Fig. 5 to 13, and between the right hand region shown in Figure 14 to 18 31, and between the base area shown in Figure 19 to 23 32.The right hand and left hand interval 30, thus 31 alternately linked end-to-end and formed chute, the explanation in more detail below of its mode, and 32 be attached at end between the base area, its mode is also with explanation in more detail below.

At first consult Fig. 5 to 13, left hand interval 30 is made up of an interval wall 33 (preferably seeing Fig. 9) and a sliding path 34 (preferably seeing Figure 10).Interval wall 33 is generally cylindrical shape and is made by high-intensity waterproof fabric as shown in Figure 9.As from Fig. 5 to 8 as seen, interval wall 33 has a top 35, which is provided with isolated a series of covers 36 on circumference.Interval wall 33 also has a bottom 31, which is provided with similar isolated cover 38.And on top 35 and following 37 adapter ring around interval wall 33 extend also have a series of pipe boxes 39 in case form one around interval wall with the passage that gets clogged.

The effect of

cover

36,38 and pipe box 39 will illustrate below.

Interval wall 33 contains a sliding path 34, can see best from Figure 10, and sliding path 34 is also made by the waterproof fabric of brute force.

Sliding path 34 has a back side 40, and there are a round and mellow limit, upper end 41 and the curvilinear 42 of an evagination in this back side.With the limit of these side 42 opposing backside surface 40 opposite sides be straight, and the back side 40 and limit, upper end 41 relative bottoms 44 also are straight.Steering surface 45 has a limit to be connected on the straight flange 43 at the back side 40, and plane, steering surface 45 place becomes an obtuse angle to the plane at the back side 40.Peripheral surface 46 is being gone along with sb. to guard him between the bottom of the side 42 at the bottom of the outside 47 of steering surface 45 and the back side with becoming curved surface.So overleaf 40, between steering surface 45 and the peripheral surface 46 with regard to forming a convergence osed top path or bag.This path terminates in the opening 48.

Sliding path 34 usefulness following manner are connected to the inboard of interval wall 33.

The limit, upper end 41 of sliding path 34 on being connected to interval inside face the time when the top 35 of the summit that make limit 41, upper end near interval wall 33.Proceed to be connected around the outside 47 of limit, upper end 41, side 42 and steering surface 45 then, until near having on the horizontal surface of cover.In addition, to have a top 50 also to be connected on interval inner face or the outside also be roughly to have on the horizontal surface of cover to peripheral surface 46.

Like this, from Fig. 5 to 8 as seen, interval wall 33 is on top crossed with the stretching, extension of oblique angle direction between 35 and following 37 in the back side 40.As shown in Figure 7,40 one-tenth obtuse angles, the 45 pairs of back side of steering surface.Hopper outlet 49 extends downwardly into outside the bottom 37 of interval wall 33.Like this, as shown in figure 13, the bottom of interval wall 33 can be pressed downward flat and can not influence the state of sliding path.This purpose will illustrate below.

Now in conjunction with between Figure 14 to 18 explanation right hand region 31.Shown in these figure, identical with left hand interval 30 to a great extent between right hand region, therefore common part will not describe in detail, just with same numeral together.Between right hand region 31 and interval 30 differences of left hand be that compare with the sliding path 34 in left hand interval 30,31 sliding path is rotated one 90 ° with respect to cover 36,38 between right hand region.Can make

cover

36,38 form a passage like this, its mode will illustrate below.

32 are made of an annulus partition 55 between the base area, have a top 5b to be provided with the identical cover 56 of cover 36 on the top 35 with the interval wall 33 in left hand interval 30 on it.But on interval wall 55, be provided with sleeve pipe 39, in its bottom 58, also do not overlap.Interval wall 55 on top the length between 56 and following 58 than the interval wall 33 in left hand interval 30 above that the length between 35 and following 37 come longly.Interval wall 55 contains one with the interior sliding path 34 identical sliding paths 59 of left hand interval 30 and use the same way as that is connected to left hand interval 30 with sliding path 34 that sliding path 59 is connected on the interval wall 55.Like this, as from Figure 18 to 22 as seen, hopper outlet 49 just has a short range to reach on the bottom 58 of interval wall 55.But can bore a hole water can be discharged by the back side 40 in the back side 40.

Chute is by 30,31 alternately linking together and form between left hand and right hand region, till reaching Len req.Interval arranged like this, the back side 40 that makes each sliding path 34 with respect to the preceding and after the back side 40 all tilt one 90 °.Inclination (cw or inhour) on same direction continues and carries out.

Interval 30,31 usefulness hoop (not shown) is interconnected.The interval 30 of the left hand or the right hand, cover 38 in the bottom 37 of a sliding path 34 of 31 can be fitted in the space between the cover 36 on the top 35 of next sliding path 34 in interval 31,30 of the right hand or left hand, and so just can form a continuous tubular conduit can be for hoop 52 within it by coupling together two kinds of intervals.These hoops for example can be made of metal.

32 also use with quadrat method and put in place between minimum left hand or right hand region on 30,31 by being connected in 36,38 passages that form by cover with hoop 52 between the base area.

Pipe box 39 between the upper and

lower limit

35,37 of each interval wall 33 also passes with hoop 53.The effect of these

hoops

52,53 is to make interval wall 33,55 keep opening allowing them to be crushed simultaneously.

Hoop 52 on the upper and

lower limit

35,37 of interval wall (rather than middle hoop 53) is connected to each other together with elastic component, and it is identical to bind round 15 elastic bodys that link together among the arrangement mode of elastic component and the top embodiment that illustrates in conjunction with Fig. 2 to 4.The escape chute of Zu Chenging also is connected between ship and the lifeboat 12 like this, and its mode is also identical with the top escape chute that illustrated in conjunction with Fig. 2 to 4.

This embodiment of escape chute mainly be uppermost interval 30,31 and the base area between form a spiral path between 32.Enter when topmost interval 30,31 personnel begin and be sitting on the back side 40 of first sliding path 34.When he slides the back side 40, just engage with steering surface 45, by steering surface 45 make it by inhour to reversing, then by hopper outlet 49, the back side 40 in the interval 30,31 of continuing with the next one engages 90 ° of the back side 40 inclinations that this back side and he left just now.The inclination arrangement at the effect of hopper outlet and the back side 40 all is personnel are utilized with the frictional engagement of the material of sliding path and the restriction that hopper outlet is provided slowly descend.Like this personnel enter behind the escape chute just can safety speed along spiral path by the sliding path that continues 34 until arrive between the base area.He just can enter in the lifeboat 12 as top illustrated in conjunction with Fig. 1 to 4 when personnel leave between the base area 32 by hopper outlet 49.

When the variable in distance between lifeboat 12 and the ship, these variations can be adapted to by the flattening and the elongation of the chute under flexible piece 24 control, and these flexible pieces can be from 32 upwards progressively chute being pressed bolt for fastening a door from outside between the base area, as top illustrated in conjunction with Fig. 1 to 4.

Because sliding path 34 is connected to the mode on the interval wall 33,55, this flattening of wall 33,55 can not make sliding path 34 press bolt for fastening a door from outside.When the escape chute contraction in length the time, they just fold mutually, therefore when personnel leave the hopper outlet in an interval 30,31, the back side 40 in the interval 30,31 that he just can continue with the next one engages, and the position that different is engages reduces downwards when extending fully than interval 30,31.

This second kind of form that should be understood that the escape chute also can have many variations.Sliding path not necessarily needs as explanation, and it can have Any shape, as long as can guide and the control personnel pass through the path of chute.Interval 30,31,32 not necessarily connect with

cover

36,38 as mentioned above, and also available other appropriate method connect.Interval wall 33,55 is not necessarily continuous, also can be jagged.
