Description
ANORDNING VED BULKSKIP FOR SANDTRANSPORT OG FLUIDISERT LOSSING BULK SHIP DEVICE FOR SAND TRANSPORT AND FLUIDIZED UNLOADING
Denne oppfinnelse vedrører et bulkskip for sandtransport og fluidisert lossing. Nærmere bestemt dreier det seg om et bulkskip for sandtransport og fluidisert lossing hvor et los-serør kommuniserer med minst ett av bulkskipets lasterom. This invention relates to a bulk ship for sand transport and fluidized unloading. More specifically, it concerns a bulk carrier for sand transport and fluidized unloading where an unloading pipe communicates with at least one of the bulk carrier's holds.
Med bulkskip menes her skip som på engelsk betegnes som "Dry Bulk Carriers". By bulk ship is meant here ships which in English are referred to as "Dry Bulk Carriers".
Ved utfylling av sjøområder for å vinne land er det ofte be-hov for store mengder masse. Ifølge kjent teknikk anvendes gjerne såkalte selvtømmende mudringsfartøy TSHD (Trailing Suction Hopper Dredges) hvor massen under transporten fra lastestedet og til lossestedet befinner seg i silolignende rom i fartøyet. Massen kan losses ved å åpne bunnen 1 fartøy-et for eksempel ved at skroget er utformet i to deler som er innrettet til å kunne forskyves i forhold til hverandre. When filling in sea areas to gain land, there is often a need for large amounts of mass. According to known technology, so-called self-emptying dredging vessels TSHD (Trailing Suction Hopper Dredges) are often used, where the mass during transport from the loading site to the unloading site is located in a silo-like space in the vessel. The mass can be unloaded by opening the bottom 1 of the vessel, for example by the hull being designed in two parts which are arranged to be able to be displaced in relation to each other.
Fartøy av den omtalte art er imidlertid ikke særlig egnet for frakt av masse i større kvantum over lengre avstander, og særlig ikke når det er tale om transport over åpne havområ-der. Årsaken er økonomisk ved at disse fartøy er relativt kostbare å bygge og å drive, samt at de har relativt begren-set lasteevne. However, vessels of the type mentioned are not particularly suitable for the transport of mass in large quantities over long distances, and especially not when it comes to transport over open sea areas. The reason is economic in that these vessels are relatively expensive to build and operate, and that they have relatively limited loading capacity.
Det er kjent å fluidisere massen før og under lossing. US- patent 3445008 beskriver således en fremgangsmåte og anordning hvor det nedre parti av fartøyets lasterom fylles med vann før vann og masse pumpes ut. It is known to fluidize the mass before and during unloading. US patent 3445008 thus describes a method and device where the lower part of the vessel's hold is filled with water before water and mass are pumped out.
Fra US-paltent 4033470 er det kjent å anvende dyser og vann under trykk for å fluidisere lasten. From US patent 4033470 it is known to use nozzles and water under pressure to fluidize the load.
For massetransport i lasterom gjelder generelt at lasterommet må være lukket og at lasten må kunne klassifiseres som tørr ved transport i åpent hav. For bulk transport in holds, it generally applies that the hold must be closed and that the cargo must be classifiable as dry when transported in the open sea.
Anvendelse av bulkskip til frakt av mudringsmasse har vært foreslått og NO-patentsøknad 19986101 beskriver en lossean-ordning som anbringes på lastens overflate og som er innrettet til å kunne fluidisere og pumpe ut lasten. Det har imidlertid vist seg at lossekapasiteten ved en slik løsning er utilstrekkelig. The use of bulk carriers for the transport of dredging material has been proposed and NO patent application 19986101 describes a lossean arrangement which is placed on the surface of the cargo and which is designed to be able to fluidize and pump out the cargo. However, it has been shown that the unloading capacity of such a solution is insufficient.
Oppfinnelsen har til formål å avhjelpe eller redusere i det minste én av ulempene ved kjent teknikk. The purpose of the invention is to remedy or reduce at least one of the disadvantages of known technology.
Formålet oppnås i henhold til oppfinnelsen ved de trekk som er angitt i nedenstående beskrivelse og i de etterfølgende patentkrav. The purpose is achieved according to the invention by the features indicated in the description below and in the subsequent patent claims.
Det er tilveiebrakt et bulkskip for sandtransport og fluidisert lossing hvor et losserør kommuniserer med minst ett av bulkskipets lasterom, og som kjennetegnes ved at losserøret er koplet til en dykket rørkopling. A bulk ship has been provided for sand transport and fluidized unloading where an unloading pipe communicates with at least one of the bulk ship's holds, and which is characterized by the unloading pipe being connected to a submerged pipe connection.
Bulkskip av denne art er relativt dyptgående, noe som resul-terer i at høyden fra lasterommets gulv, ofte betegnet tank-topp, og opp til dekket er relativt stor. Ved å anordne en kopling under vann kan losserøret tilkoples en ekstern slurrypumpe uten å måtte lede losserøret over skipets dekk. Rørkoplingen kan, avhengig av praktiske forhold, befinne seg i bulkskipets side, bunn eller annet hensiktsmessig sted for tilkopling til en sandmottaker som fortrinnsvis er forsynt med en dykket slurrypumpe. Bulk carriers of this type are relatively deep-drafting, which results in the height from the floor of the hold, often referred to as tank top, up to the deck being relatively large. By arranging a connection underwater, the discharge pipe can be connected to an external slurry pump without having to lead the discharge pipe over the ship's deck. The pipe connection can, depending on practical conditions, be in the side, bottom or other suitable place of the bulk carrier for connection to a sand receiver which is preferably equipped with a submerged slurry pump.
Rørkoplingen kan omfatte en første koplingsdel som er koplet til bulkskipet og en løsbar andre koplingsdel som er koplet til sandmottakeren. The pipe connection may comprise a first connection part which is connected to the bulk ship and a detachable second connection part which is connected to the sand receiver.
Den løsbare andre koplingsdel kan være forsynt med ledetau i form av et tau, wire, kjetting eller lignende som koples til koplingsdelen og som typisk anvendes til å trekke den andre koplingsdel inn på den første koplingsdel. The detachable second coupling part can be provided with a guide rope in the form of a rope, wire, chain or the like which is connected to the coupling part and which is typically used to pull the second coupling part onto the first coupling part.
Den løsbare andre koplingsdel kan også forskyves inn på eller i den første koplingsdel ved hjelp av en manipulatorarm som befinner seg på bulkskipets utside. The detachable second coupling part can also be moved onto or in the first coupling part by means of a manipulator arm located on the outside of the bulk carrier.
Den løsbare andre kopling kan være utformet til komplementært å passe i et innstyringsparti på bulkskipet. Innstyringspartiet kan for eksempel være traktformet eller utgjøres av en føring. The releasable second coupling may be designed to complementarily fit into a steering portion of the bulk carrier. The guide part can, for example, be funnel-shaped or consist of a guide.
Losserøret kan valgbart være koplet til sjøvannsinntak. Sjø-vannsinntaket kan for eksempel anvendes til innfylling av sjøvann i et lasterom før lossing skal igangsettes og til gjennomspyling av losserøret ved oppstart av slurrypumpen. The discharge pipe can optionally be connected to a seawater intake. The seawater intake can, for example, be used to fill a hold with seawater before unloading is to begin and to flush the discharge pipe when the slurry pump is started.
Losserøret kan valgbart være koplet til dreneringsrør i minst ett lasterom. Losserøret kan derved anvendes til drenering av overskuddsvann fra lasterommet under lasting av fluidisert sand. Losserøret kan være valgbart koplet til en dreneringspumpe for transport av overskuddsvann fra lasterommet og ut av bulkskipet. Dreneringspumpen kan med fordel befinne seg om bord i bulkskipet. The discharge pipe can optionally be connected to a drainage pipe in at least one hold. The discharge pipe can thereby be used to drain excess water from the hold during loading of fluidized sand. The discharge pipe can optionally be connected to a drainage pump for the transport of excess water from the hold and out of the bulk carrier. The drainage pump can advantageously be located on board the bulk carrier.
Bulkskipet kan være forsynt med stengbare dreneringsåpninger i skipssiden hvor vann renner ut når det når et bestemt nivå i lasterommet. The bulk carrier can be fitted with closable drainage openings in the side of the ship where water flows out when it reaches a certain level in the hold.
Et lasterør som forløper langs bulkskipet er valgbart koplet til lasterommene. Den fluidiserte sand tilføres via en lastekopling fra et mudringsfartøy og ledes til ønsket lasterom hvor den fluidiserte sand spredes ved hjelp av en spredea-nordning. A cargo pipe that runs alongside the bulk carrier is optionally connected to the holds. The fluidized sand is supplied via a loading connection from a dredging vessel and is directed to the desired hold where the fluidized sand is spread using a spreading device.
Lasterøret kan være valgbart tilkoplet fluidiseringsrør som befinner seg i lasterommets nedre parti. Vann for fluidisering av sanden under lossing kan derved tilføres via lastekoplingen og lasterøret til det lasterom som skal losses. The cargo pipe can optionally be connected to a fluidization pipe located in the lower part of the cargo space. Water for fluidizing the sand during unloading can thereby be supplied via the loading connection and the loading pipe to the hold to be unloaded.
Anordningen ifølge oppfinnelsen muliggjør anvendelse av en ekstern slurrypumpe under lossing av fluidisert sand fra bulkskip. Oppfinnelsen bidrar derved til å gjøre transport av sand over lenger distanser økonomisk gjennomførbar, idet kon-vensjonelle bulkskip for en relativt beskjeden kostnad kan klargjøres for slik transport. The device according to the invention enables the use of an external slurry pump during unloading of fluidized sand from bulk carriers. The invention thereby contributes to making the transport of sand over longer distances economically feasible, as conventional bulk carriers can be prepared for such transport for a relatively modest cost.

Et losserør 24 er anordnet på tanktoppen 22 og forløper gjennom skottene 6 langs bulkskipet 1, se fig. 3 og 4. Losserøret 24 kommuniserer med de lasterom 2 som anvendes for sandlast via respektive losseventiler 26. Losserøret 24 er ved sitt midtparti via koplingsventiler 28 koplet til en rørkopling 30. Ved sine endepartier er losserøret 24 via inntaksventiler An unloading pipe 24 is arranged on the tank top 22 and extends through the bulkheads 6 along the bulk carrier 1, see fig. 3 and 4. The unloading pipe 24 communicates with the cargo spaces 2 used for sand cargo via respective unloading valves 26. The unloading pipe 24 is connected at its middle part via coupling valves 28 to a pipe coupling 30. At its end parts, the unloading pipe 24 is via intake valves
32 koplet til sjøvannsinntak 34. 32 connected to seawater intake 34.
Losserøret 24 er via dreneringsventiler 36 koplet til drene-ringsrør 3 8 i form av dreneringstårn av i og for seg kjent utførelse. The discharge pipe 24 is via drainage valves 36 connected to drainage pipe 38 in the form of a drainage tower of known design per se.
En dreneringspumpe 4 0 er via en treveis pumpeventil 42 koplet til losserøret 24 og til et pumpeinntak 43 for sjøvann. Dre-neringspumpens 40 utløp 44 munner ut utenfor bulkskipet 1 over eller under vann. Utløpet 44 er via en treveisventil 45 og et mellomrør 47 koplet til lasterøret 8 for å kunne levere fluidiseringsvann til lasterommene 2, se fig. 3 og 5. A drainage pump 40 is via a three-way pump valve 42 connected to the unloading pipe 24 and to a pump inlet 43 for seawater. The outlet 44 of the drainage pump 40 opens outside the bulk carrier 1 above or below water. The outlet 44 is via a three-way valve 45 and an intermediate pipe 47 connected to the cargo pipe 8 in order to be able to supply fluidizing water to the cargo spaces 2, see fig. 3 and 5.
I denne foretrukne utførelsesform er rørkoplingen 30 anordnet i bulksipets 1 skipsside 46, idet en første koplingsdel 48 er koplet til skipssiden 46 ved hjelp av et traktformet innstyringsparti 50. In this preferred embodiment, the pipe coupling 30 is arranged in the ship side 46 of the bulk siphon 1, a first coupling part 48 being connected to the ship side 46 by means of a funnel-shaped guide part 50.
En andre koplingsdel 52 er via et fleksibelt rør 54, for eksempel i form av en slange, koplet til en ikke vist sandmottaker. Den andre koplingsdel 52 er innrettet til å kunne trekkes inn i den første koplingsdel 48 ved hjelp av et ledetau 56. A second connecting part 52 is via a flexible pipe 54, for example in the form of a hose, connected to a sand receiver, not shown. The second coupling part 52 is designed to be pulled into the first coupling part 48 by means of a guide rope 56.
Losserøret 24 er koplet til den første koplingsdel 48 via koplingsventilene 28. Den første koplingsdel 48 omfatter et hovedrør 58 som har større innvendig diameter enn losserørets 24 utvendige diameter, idet hovedrøret 58 forløper fra en overgangshylse 60 hvor det er koplet til losserøret 24, og til innstyringspartiet 50. Hovedrøret 58 utgjør en tettende forbindelse mellom losserøret 24 og skipssiden 46. The unloading pipe 24 is connected to the first connecting part 48 via the connecting valves 28. The first connecting part 48 comprises a main pipe 58 which has a larger internal diameter than the external diameter of the unloading pipe 24, the main pipe 58 extending from a transition sleeve 60 where it is connected to the unloading pipe 24, and to the steering part 50. The main pipe 58 forms a sealing connection between the unloading pipe 24 and the ship's side 46.
Ledetauet 56 forløper forskyvbart gjennom overgangshylsen 60 via fortrinnsvis to pakkbokser 62, se fig. 10. Det kan med fordel monteres en ikke vist lekkasjedetektor mellom pakkbok-sene. The guide rope 56 extends displaceably through the transition sleeve 60 via preferably two packing boxes 62, see fig. 10. A leak detector (not shown) can advantageously be fitted between the packing boxes.
Losserøret 24 er ved sitt inn i den første koplingsdel 48 vendende endeparti utformet med en konisk tetningsflate 64. The unloading pipe 24 is designed with a conical sealing surface 64 at its end facing into the first connecting part 48.
Hovedrøret 58 er innvendig forsynt med to pakningsringholdere 6 6 med fortrinnsvis oppblåsbare ringpakninger 68. Mellom pak-ningsringholderne 66 er det anordnet en styrehylse 70. The main pipe 58 is internally provided with two packing ring holders 6 6 with preferably inflatable ring packings 68. Between the packing ring holders 66 a guide sleeve 70 is arranged.
I utsparinger 72 i styrehylsen 70 er det anordnet aktuatorer 74 i form av hydraulikksylindre som er koplet til hver sin inntrekkingskrok 76. Inntrekkingskroken 76, som ligger an mot et skråstilt anslag 78, er innrettet til å kunne forskyves radalt innover relativt hovedrøret 58 når den forskyves mot losserøret 24 i hovedrøret 58. Actuators 74 in the form of hydraulic cylinders are arranged in recesses 72 in the control sleeve 70, which are each connected to a retracting hook 76. The retracting hook 76, which rests against an inclined stop 78, is arranged to be able to be displaced radially inward relative to the main pipe 58 when it is displaced towards the unloading pipe 24 in the main pipe 58.
Den andre koplingsdel 52 omfatter et utvendig lederør 80 samt et innvendig rør 82 som er koplet til det fleksible rør 54. Ved sitt ledende endeparti er den andre koplingsdel 52 utformet med et innvendig konisk endering 84 som komplementært passer på losserørets 24 koniske tetningsflate 64. Enderingen 84 som tettende forbinder det utvendige lederører 80 med det innvendige rør 82, er forsynt med et feste 86 for ledetauet 56.

The second connecting part 52 comprises an external guide pipe 80 and an internal pipe 82 which is connected to the flexible pipe 54. At its leading end part, the second connecting part 52 is designed with an internal conical end ring 84 which complementarily fits on the conical sealing surface 64 of the unloading pipe 24. The end ring 84, which sealingly connects the outer guide lugs 80 with the inner tube 82, is provided with a fastener 86 for the guide rope 56. A hook 88, which is designed to be gripped by the retracting hooks 76, encircles the guide tube 80.
Når bulkskipet 1 skal lastes, koples det ikke viste mudrings-fartøy til lastkoplingen 10. Lastventilen 12, som korresponderer med det lasterom 2 som skal lastes, åpnes, hvoretter fluidisert sand pumpes via lastkoplingen 10, lasterøret 8 og den aktuelle lastventil 12 og inn i lasterommet 2. Den fluidiserte sand faller ned på fordelingsplaten 14 og spredes i lasterommet 2. Samtidig strømmer overskytende vann fra laste rommet 2 via dreneringsrøret 38, dreneringsventilen 36, los-serøret 24, pumpeventilen 42, dreneringspumpen 40 og utløpet 44 ut i sjøen. Når lastingen er ferdig, stenges drene-ringsventilene 36 og pumpeventilen 42, idet dreneringspumpen When the bulk carrier 1 is to be loaded, the dredging vessel, not shown, is connected to the cargo coupling 10. The cargo valve 12, which corresponds to the cargo compartment 2 to be loaded, is opened, after which fluidized sand is pumped via the cargo coupling 10, the cargo pipe 8 and the relevant cargo valve 12 and into hold 2. The fluidized sand falls onto the distribution plate 14 and is spread in hold 2. At the same time, excess water flows from hold 2 via the drainage pipe 38, the drainage valve 36, the discharge pipe 24, the pump valve 42, the drainage pump 40 and the outlet 44 into the sea. When the loading is finished, the drain valves 36 and pump valve 42 are closed, as the drain pump
40 stanses. 40 is stopped.
Før lossing kan ett eller flere lasterom 2 tilføres vann via sjøvannsinntakene 34, inntaksventilene 32, losserøret 24 og losseventilene 26. Når ønsket vannmengde er innfylt i lasterommene, stenges losseventilene 26. Before unloading, one or more holds 2 can be supplied with water via the seawater intakes 34, the intake valves 32, the discharge pipe 24 and the discharge valves 26. When the desired amount of water has been filled in the holds, the discharge valves 26 are closed.
Ledetauet 56, som når de ikke er i bruk forløper gjennom den første koplingsdel 48 og opp langs skipssiden 46, koples ved hjelp av festet 86 til den andre koplingsdels 52 endering 84. The guide rope 56, which when not in use runs through the first connecting part 48 and up along the ship's side 46, is connected by means of the attachment 86 to the end ring 84 of the second connecting part 52.
Den andre koplingsdel 52 trekkes deretter ved hjelp av ledetauet 56 inn gjennom innstyringspartiet 50 og den første koplingsdel 48 slik det er vist i fig. 8 hvor den andre koplingsdel 52 trekkes inn i styrehylsen 70. I fig. 9 befinner den andre koplingsdel 52 seg i sin tilkoplede posisjon i den første koplingsdel 48, idet aktuatorene 74 har forskjøvet sine respektive inntrekningskroker 76 til anslag mot hake-ringen 88 og forskjøvet den koniske endering 84 til tettende anslag mot den koniske tetningsflate 64. Ringpakningene 6 8 er aktivert og tetter mot lederøret 80. En ikke vist lekkasjedetektor kan anordnes mellom ringpakningene 68. The second connecting part 52 is then pulled in with the help of the guide rope 56 through the guide part 50 and the first connecting part 48 as shown in fig. 8 where the second coupling part 52 is pulled into the control sleeve 70. In fig. 9, the second coupling part 52 is in its connected position in the first coupling part 48, the actuators 74 having moved their respective retracting hooks 76 to abut against the hook ring 88 and moved the conical end ring 84 to a sealing abutment against the conical sealing surface 64. The ring seals 6 8 is activated and seals against the guide pipe 80. A leak detector, not shown, can be arranged between the ring seals 68.
Deretter kan koplingsventilene 28 åpnes og den ikke viste slurrypumpe startes. Vann sirkuleres derved fra sjøvannsinn-takene 34, via losserøret 24, koplingsventilene 26, rør-koplingen 30 og det fleksible rør 54. Når inntaksventilene 32 stenges og de aktuelle losseventiler 26 åpnes, strømmer fluidisert sand fra lasterommet 2 via losseventilene 26, losserø-ret 24, koplingsventiler 26 og rørkoplingen 30 ut av bulkskipet 1. The coupling valves 28 can then be opened and the slurry pump, not shown, started. Water is thereby circulated from the seawater intakes 34, via the unloading pipe 24, the coupling valves 26, the pipe coupling 30 and the flexible pipe 54. When the intake valves 32 are closed and the relevant unloading valves 26 are opened, fluidized sand flows from the hold 2 via the unloading valves 26, the unloading pipe 24, connecting valves 26 and the pipe connection 30 out of the bulk carrier 1.
Sjøvann for fluidisering av sanden i lasterommene 2 pumpes inn via lastekoplingen 10, lasterøret 8, den aktuelle fluidi-seringsventil 16, fallrøret 18 og fluidiseringsrørene 20. Al-ternativt kan sjøvann for fluidisering pumpes inn i lasterø-ret 8 via pumpeinntaket 43, pumpeventilen 42, dreneringspumpen 40, treveisventilen 45 og mellomrøret 47. Seawater for fluidizing the sand in the hold spaces 2 is pumped in via the cargo coupling 10, the cargo pipe 8, the relevant fluidization valve 16, the drop pipe 18 and the fluidization pipes 20. Alternatively, seawater for fluidization can be pumped into the cargo pipe 8 via the pump inlet 43, the pump valve 42 , the drainage pump 40, the three-way valve 45 and the intermediate pipe 47.
Når lossingen er utført, koples den andre koplingsdel 52 fra den første koplingsdel 4 8 som beskrevet over, men i motsatt rekkefølge. When the unloading has been carried out, the second coupling part 52 is connected from the first coupling part 4 8 as described above, but in the opposite order.
I en alternativ utførelsesform, se fig. 11, er rørkoplingen 3 0 utformet med en andre koplingsdel 52 som er forsynt med en rørflens 90. Rørflensen 90 er forskyvbar i et føringsformet innstyringsparti 92 som er festet til skipssiden 46. Rørflen-sen 90 korresponderer med en tetningsdel 94 på den første koplingsdel 48 hvor tetningsdelen 94 omfatter en ekspanderbar pakning 96. Det føringsformede innstyringsparti 92 ved tetningsdelen 94 kan være forspennbart i retning mot skipssiden 46 . In an alternative embodiment, see fig. 11, the pipe coupling 30 is designed with a second coupling part 52 which is provided with a pipe flange 90. The pipe flange 90 is displaceable in a guide-shaped guide part 92 which is attached to the ship's side 46. The pipe flange 90 corresponds to a sealing part 94 on the first coupling part 48 where the sealing part 94 comprises an expandable gasket 96. The guide-shaped guide part 92 at the sealing part 94 can be biased in the direction towards the ship's side 46.
Når den andre koplingsdel 52 ifølge denne alternative utfø-relsesf orm skal koples til den første koplingsdel 48, føres rørflensen 90 til inngrep i det føringsformede innstyringsparti 92, hvoretter den andre koplingsdel 52 forskyves langs det føringsformede innstyringsparti inntil rørflensen 90 korresponderer med tetningsdelen 94, hvoretter pakningen When, according to this alternative embodiment, the second coupling part 52 is to be connected to the first coupling part 48, the pipe flange 90 is brought into engagement with the guide-shaped guide part 92, after which the second coupling part 52 is displaced along the guide-shaped guide part until the pipe flange 90 corresponds with the sealing part 94, after which the gasket
96 aktiveres. Fråkopling fortas i motsatt rekkefølge. 96 is activated. Disconnection is carried out in the opposite order.
