Description
Anordning for lasting og lossing av tankskip for flytende gass.Device for loading and unloading liquefied gas tankers.
På grunn av den okende energiknapphet og de store prisstignin-ger på energisektoren, gjoresi dag store anstrengelser for å Due to the increasing scarcity of energy and the large price increases in the energy sector, great efforts are currently being made to
ta i bruk også slike energikilder som hittil ikke har vært oko-nomisk eller teknisk drivbare. Dette gjelder også utnyttelsen av olje- og gasskilder og transport og raffinering av olje og gass i havområder med systemer som enten er flytende eller forankret i havbunnen. Hvis.slike produksjonssteder ikke kan koples til forbruks- eller omlastingssentra, må produktene som er also use energy sources that have not been economically or technically feasible up to now. This also applies to the utilization of oil and gas sources and the transport and refining of oil and gas in sea areas with systems that are either floating or anchored to the seabed. If.such production sites cannot be connected to consumption or transshipment centres, the products that are
behandlet for transport, lastes ombord i tankskip og fraktes videre med disse. Lasting og lossing av tankskip i havner og i rolig sjo er riktignok teknisk sett upåklagelig lost, men den praktiske gjennomforing krever stor dyktighet, hvis store tankskip som skal lasses eller losses må manovreres. processed for transport, loaded on board tankers and transported on with these. Loading and unloading of tankers in harbors and in calm seas is technically impeccable, but the practical implementation requires great skill, if large tankers to be loaded or unloaded have to be manoeuvred.
Vanskelighetene oker betydelig når lastingen skal foregå i åpen sjo, især i grov sjo. De problemer som oppstår i denne forbindelse, især ved lasting av tankere for flytendegjort gass, er hittil ikke eller i det minste utilfredsstillende lost. I videre forstand gjelder dette også lasting av oljetankskip. I over-ensstemmelse med teknikkens stilling, må tankskipet enten seiles svært nær inntil produksjons- og lagringsplattformen med tilsvarende kollisjonsrisiko eller seiles inntil en separat boye med overforingsinnretninger som bærer tilkoplingspunktet for tilfor-selsledningen. I begge tilfelle oppstår det betydelige problemer, idet det ved grov sjo oppstår tilsvarende store relativbevegel-ser mellom de to ledningssystemer som skal koples sammen. Det vil uten videre forstås at de nodvendige tilkoplinger bare kan The difficulties increase significantly when loading is to take place in open seas, especially in rough seas. The problems that arise in this connection, especially when loading tankers for liquefied gas, have so far not been resolved, or at least not satisfactorily resolved. In a broader sense, this also applies to the loading of oil tankers. In accordance with the state of the art, the tanker must either be sailed very close to the production and storage platform with a corresponding risk of collision or be sailed to a separate buoy with transfer devices that carry the connection point for the supply line. In both cases, significant problems arise, as in the case of rough seas correspondingly large relative movements occur between the two wiring systems that are to be connected together. It will be understood without further ado that the necessary connections can only
opprettes pålitelig med stor dyktighet og at uhell ofte ikke lar seg unngå. is created reliably with great skill and that accidents are often unavoidable.

i Det tekniske problem ligger således i tilveiebringelse av en i i ' anordning- med hvilken store tankskip, især tankskip for flyten-' degjort gass, kan lastes uavhengig av sjogangen i åpen sjo. En slik anordning kan selvsagt også benyttes omvendt, dvs. til lossing. The technical problem thus lies in the provision of a device with which large tankers, especially tankers for liquefied gas, can be loaded independently of the seaway in open seas. Such a device can of course also be used in reverse, i.e. for unloading.
For å lose denne oppgave går oppfinnelsen ut fra en anordning for lasting og lossing, især av tankskip for flytendegjort gass i åpen sjo, ved bruk av en ledning som er lagt i vannet og et flytende legeme som er anbrakt på den ledningsende som vender mot skipet og som er forsynt med organer for tilkopling til skipets ledninger. Oppgaven loses ved at anordningen, er utfort slik at ballastorganer holder ledningen i en bestemt dybde og at ledningen i den ende som vender mot skipet er tilsluttet et ror som holdes i det vesentlige vertikalt av flytelegemet. Ifolge oppfinnelsen er roret videre begrenset fleksibelt og flytelegemet er utstyrt med rullefendere. To solve this task, the invention is based on a device for loading and unloading, in particular of tankers for liquefied gas in open sea, using a line that is laid in the water and a floating body that is placed on the end of the line that faces the ship and which are provided with means for connection to the ship's cables. The task is solved by the device being laid out so that ballast elements hold the cable at a certain depth and that the cable at the end facing the ship is connected to a rudder which is held essentially vertically by the floating body. According to the invention, the rudder is further limited in flexibility and the floating body is equipped with roller fenders.
Anordningen ifolge oppfinnelsen gjor det mulig at et skip kan fortoyes til plattformen som danner produksjons- eller omlastingspunktet med baugtrosser i en avstand på minst en halv skipslengde, hvorved trossene ved innhaling lett kan holdes stramme mot plattformen. Det kan videre uten vanskelighet oppnås at hele systemet som omfatter plattformen og skipet, under lasting retter seg opp med vinden i avhengighet av vind- og bolgebeve-gelser om et festepunkt som ligger eksentrisk i forhold til nevnte system. Overleverings- hhv. overtagningsledningene som må anordnes mellom plattformen og skipet ligger i det vesentlige utenfor sjogangens påvirkning, slik at slitasje og brudd og den dermed forbundne fare for uhell unngås. Ledningen forblir i det vesentlige på samme dybde under hele manovreringen, også under til- og fråkopling av skipsledningen, og bare flytelegemet, som fores frem til skipet med egen fremdrift eller av en slepebåt, blir loftet opp av vannet ved skipet, hvorved roret, som folge av sin begrensede fleksibilitet og på grunn av strekket, som virker i nedre ende som folge av ledningstilkoplingen, boyes noe bort fra skipsveggen. Når flytelegemet er loftet opp av vannet, kan The device according to the invention makes it possible for a ship to be moored to the platform that forms the production or transshipment point with bow lines at a distance of at least half the ship's length, whereby the lines can easily be kept tight against the platform when hauling in. It can also be achieved without difficulty that the entire system, which includes the platform and the ship, aligns with the wind during loading in dependence on wind and wave movements about an attachment point that is eccentric in relation to said system. Delivery or the take-over cables that must be arranged between the platform and the ship are essentially outside the influence of the seaway, so that wear and tear and the associated risk of accidents are avoided. The cable remains essentially at the same depth during the entire manoeuvring, also during connection and disconnection of the ship's cable, and only the floating body, which is guided to the ship under its own propulsion or by a tugboat, is lifted out of the water by the ship, whereby the rudder, which as a result of its limited flexibility and due to the stretch, which acts at the lower end as a result of the cable connection, it is bowed somewhat away from the ship's wall. When the floating body is lifted out of the water, can
koplingsstykket på flytelegemet koples.til en skipsledning, upå-virket av sjogangen, hvorpå overleveringen kan settes i gang. the connecting piece on the floating body is connected to a ship's cable, unaffected by the seaway, after which the handover can be started.

For dette formål er ledningen utformet som slangeledning. Når anordningen : The device according to the invention can be designed so that the line in and the floating body which is located at its delivery end are only driven out for a loading operation at any time. For this purpose, the cable is designed as a hose cable. When the device

Ytterligere fordeler og trékk ved oppfinnelsen vil fremgå av kravene og av nedenstående beskrivelse og tegningen, hvor oppfinnelsen er beskrevet hhv. vist ved utforelseseksempler. Fig. 1 viser en anordning ifolge oppfinnelsen skjematisk og i perspektiv, idet anordningen forbinder en produksjons- eller lagringsplattform som er forankret i åpen sjo med et skip som skal lastes. Fig. 2 og 3 viser den ende av anordningen som befinner seg i retning av skipet ved innledningen av lasting. Fig. 1 viser en plattform 20, som flyter avlands og bærer et anlegg for flytendegjoring av jordgass og en lagringsbeholder for den flytendegjorte gass. Plattformen kan f.eks. via en ledning 12 være tilknyttet et borehullhode 10, som er markert med en boye 14. Punkt 10 er samtidig forankringssentret med stag 18, som overtar strekket som utoves på punkt 11 ovenfor anordningen 10 av trossene 16. Skipet 22 er fortoyd til plattformen med. Further advantages and features of the invention will be apparent from the claims and from the following description and drawing, where the invention is described or shown by embodiment examples. Fig. 1 shows a device according to the invention schematically and in perspective, the device connecting a production or storage platform which is anchored in open sea with a ship to be loaded. Fig. 2 and 3 show the end of the device which is in the direction of the ship at the beginning of loading. Fig. 1 shows a platform 20, which floats offshore and carries a plant for liquefaction of natural gas and a storage container for the liquefied gas. The platform can e.g. via a wire 12 be connected to a borehole head 10, which is marked with a buoy 14. Point 10 is at the same time the anchoring center with stay 18, which takes over the stretch as extended at point 11 above the device 10 of the cables 16. The ship 22 is moored to the platform with.
trosser 24, slik at det opprettholdes en minsteavstand på en halv skipslengde mellom skipet 22 og plattformen 20. Av fig. 1 fremgår at systemet som består av plattformen 20 og skipet 22 kan svinge om punkt 10. Faren for kollisjon mellom skipet 22 og plattformen 20 er utelukket ved en slik avstand og anordning. tackles 24, so that a minimum distance of half a ship's length is maintained between the ship 22 and the platform 20. From fig. 1 shows that the system consisting of the platform 20 and the ship 22 can swing about point 10. The danger of collision between the ship 22 and the platform 20 is ruled out by such a distance and arrangement.
Den avstand mellom skip 22 og plattform 20 som må velges av sik-kerhetsgrunner, utelukker dog også at det benyttes en vanlig ledningsslange til lasting av skipet 22. På grunn av anordnin-gens bevegelighet kan det heller"ikke benyttes en vanlig rorled-ning av stive ror. Ifolge oppfinnelsen benyttes derfor en led-i The distance between ship 22 and platform 20, which must be chosen for safety reasons, also precludes the use of a normal cable hose for loading the ship 22. Due to the device's mobility, a normal rudder line of rigid rudders According to the invention, a led-i is therefore used

I det viste eksempel er ledningen 26 forsynt med lodd e.l. og via tau 34 forbundet med oppdriftslegemer 32, som i sin tur er innbyrdes forbundet med trosser 36, slik at delene 26,32,34,36 danner et system som flyter i en bestemt vanndybde. I den ende som vender mot skipet er ledningen 26 koplet til et ror 28, som i det vesentlige holdes vertikalt av et flytelege-me 30. Tilkoplingen er opprettet via en svivelforbindelse. For lasting blir. flytelegemet 30 loftet opp av vannet med loftean-ordninger ombord på skipet 22, slik at koplingsstykket i ovre ende av roret 28 ligger utenfor sjogangens påvirkning. Deretter kan tilkoplingen av skipsledningene til rorets 28 ovre koplingsstykke opprettes med automatisk koplende forbindelser og lasting kan settes i gang. 'water depth, where it is essentially outside the influence 1 of the viewing channel. In the example shown, the wire 26 is provided with solder etc. and via rope 34 connected to buoyancy bodies 32, which in turn are interconnected with ropes 36, so that the parts 26,32,34,36 form a system that floats in a specific water depth. At the end facing the ship, the line 26 is connected to a rudder 28, which is essentially held vertically by a floating body 30. The connection is made via a swivel connection. For loading will be. the floating body 30 lofted out of the water with loft-an arrangements on board the ship 22, so that the coupling piece at the upper end of the rudder 28 is outside the influence of the seaway. The connection of the ship's cables to the rudder's 28 upper connection piece can then be established with automatically connecting connections and loading can be started.
Fig. 2 og 3 viser en utforelsesform som er modifisert med hen-blikk på slangen. I dette tilfelle er det anordnet en slange 26', og parallelt med og nedenfor denne forloper to ballastslanger 52. Ballastslangene 52 ender i en forbindelsesboyle 54, via hvilken slangenes indre rom også står.i forbindelse med hverandre. Det er således mulig å endre fyllingen av ballastslangene 52 og dermed ballastverdien fra plattformen 20 ved pumping av væsker med annen sammensetning til ballastslangene. Ballastslangene 52 er ved hjelp av tau 53 eller steg forbundet med hverandre og med slangen 25, som derved belastes jevnt over det hele. Fig. 2 and 3 show an embodiment which has been modified with regard to the hose. In this case, a hose 26' is arranged, and two ballast hoses 52 run parallel to and below this. The ballast hoses 52 end in a connecting pipe 54, via which the inner spaces of the hoses are also connected to each other. It is thus possible to change the filling of the ballast hoses 52 and thus the ballast value from the platform 20 by pumping liquids with a different composition to the ballast hoses. The ballast hoses 52 are connected to each other and to the hose 25 by means of ropes 53 or steps, which are thereby loaded evenly over the whole.
Slangen 26' er via et koplingsstykke 38' forbundet med nedre ende av roret 28. Koplingsstykket 38' inneholder minst en svivel-, kopling som sorger for at slangen med sitt koplingsstykke forblir bevegelig overfor roret 28. Fortrinnsvis, se fig. 3, omfatter meilomstykket 38' et stag 39, via hvilket boylen 54 er fast og stivt forbundet med slangekoplingen. The hose 26' is via a coupling piece 38' connected to the lower end of the rudder 28. The coupling piece 38' contains at least one swivel coupling which ensures that the hose with its coupling piece remains movable relative to the rudder 28. Preferably, see fig. 3, the intermediate piece 38' comprises a stay 39, via which the boylen 54 is firmly and rigidly connected to the hose coupling.
Roret 28 er omgitt av et beskyttelsesror 29, som er festet på nedsiden av flytelegemet 30. Rorene 29 og 28 har begrenset fleksibilitet, slik at det ved utovelse av strekk mot nedre tilknytningsende kan oppstå en lett boyning. Roret 28 er fast anordnet The rudder 28 is surrounded by a protective rudder 29, which is attached to the underside of the floating body 30. The rudders 29 and 28 have limited flexibility, so that a slight boying can occur when stretching towards the lower connection end. The rudder 28 is fixed
i flytelegemet 30 og rager opp fra flytelegemet med sin ovre tilknytningsende 50 som er omgitt av en beskyttende krage 48. in the floating body 30 and protrudes from the floating body with its upper connecting end 50 which is surrounded by a protective collar 48.

Usually it will be sufficient to have a floating body that is towed with a boat up to the ship 22, as a boat is also necessary for cable transfer.
Flytelegemet 30 er fortrinnsvis utfort i likhet med et skips-skrog og har storre utstrekning i lengderetningen, som i fig. 2 forloper horisontalt fra venstre mot hoyre, enn på tvers, se også fig. 3.

On the opposite ends, a cushion 46 is placed for attaching ropes 44 from the ship 22. With the help of the ropes 44 and one or two winches 45, the floating body 30 can be lifted as high as
opp av vannet at det forblir utenfor bolgetoppendes rekkevidde og ligger i ro i anlegg mot skipets yttervegg. Flytelegemet 30 out of the water so that it remains out of reach of the top of the hull and rests in contact with the ship's outer wall. The floating body 30
er for dette formål forsynt med rullefendere 40,41, som er av-stottet på flytelegemet via et trekantfeste 42 og i sin tur mu-liggjor avstottingen mot skipets 22 yttervegg uten at det opp-trer skader. is for this purpose provided with roller fenders 40,41, which are supported on the floating body via a triangular attachment 42 and in turn enable the support against the outer wall of the ship 22 without damage occurring.
Etter at flytelegemet 30 er loftet opp, se også fig. 1, vil skipet og flytelegemet befinne seg i en statisk definert stil-, ling i forhold til hverandre. I denne stilling kan skipets ledningsnett uten vanskeligheter koples til koplingsstykket på flytelegemet ved kjente anordninger og uten vanskeligheter. Når lasten er fort ombord gjennom ledningen 26 og roret 28, koples skipets ledningsnett igjen fra- roret 28, flytelegemet slippes ned langs skipsveggen og trossene 44 lbsnes. Flytelegemet 30 og dermed også ledningen 26 hhv. 26' kan deretter fores tilbake til plattformen 20, hvor den fleksible slange- hhv. ledningsfor-bindelse mellom flytelegemet og plattformen og selve flytelegemet tas opp av vannet og plasseres ovenfor vannlinjen. I stedet for en slange for ledningen 26 hhv. 26' kan det også benyttes en ledning som består av et tilsvarende fleksibelt ror eller fleksibelt sammenkoplede rbrlengder. After the floating body 30 has been lifted up, see also fig. 1, the ship and the floating body will be in a statically defined position in relation to each other. In this position, the ship's wiring harness can be connected to the connector on the floating body using known devices and without difficulty. When the cargo is quickly on board through the cable 26 and the rudder 28, the ship's wiring harness is again disconnected from the rudder 28, the floating body is lowered along the ship's wall and the ropes 44 are lifted. The floating body 30 and thus also the line 26 or 26' can then be fed back to the platform 20, where the flexible hose or cable connection between the floating body and the platform and the floating body itself is taken out of the water and placed above the waterline. Instead of a hose for the wire 26 or 26', a line consisting of a corresponding flexible tube or flexibly connected tube lengths can also be used.
