Abstract
Ettpunkts fortøynings- og lastesystem.One-point mooring and loading system.
Description
Foreliggende oppfinnelse angår et ettpunkts for-tøynings- og lastesystem for et tankfartøy, omfattende et for-tøynings fundament som er forankret til eller på annen måte ligger i stilling på sjøbunnen, mens en fortøyningsbøye er forbundet med fundamentet ved hjelp av en enkel forankring, hvis akse faller sammen med aksen for fortøyningsfundamentet. Forankringen har en slik lengde at bøyen holdes nede mot sin oppdrift ved eller nær overflaten av sjøen og bøyen har anord-ninger for dreibar opptagelse av en fortøyningsbelastning fra et fartøy som er fortøyet direkte i bøyen. Forankringen opptar hele fortøyningsbelastningen når fartøyet er fortøyet, og omfatter en lastførende stiv aksel som er festet ikke-dreibart The present invention relates to a one-point mooring and loading system for a tanker, comprising a mooring foundation which is anchored to or otherwise lies in position on the seabed, while a mooring buoy is connected to the foundation by means of a simple anchoring, if axis coincides with the axis of the mooring foundation. The anchoring has such a length that the buoy is held down against its buoyancy at or near the surface of the sea and the buoy has devices for rotatably receiving a mooring load from a vessel that is moored directly in the buoy. The mooring takes up the entire mooring load when the vessel is moored, and comprises a load-carrying rigid shaft which is attached non-rotatably
til fortøyningsfundamentet og er tilknyttet en lastsvivel som er koaksial med og anbragt i tettende forhold til den stive aksel. Fra svivelen løper det ut en lastledning for overføring av to the mooring foundation and is connected to a load swivel which is coaxial with and arranged in sealing relation to the rigid axle. A load line runs out from the swivel for transfer
last direkte fra svivelen til tankfartøyet. load directly from the swivel to the tanker.
Det er for eksempel fra britisk patent nr.1.097.258 tidligere kjent et system der lastoverføringsarmen 22 omfatter en leddet del som normalt ligger under havflaten og hviler på havbunnen. Armen har oppdriftsmidler, f.eks. i form av tanker, for å muliggjøre hevning av armen til havflaten når systemet er There is, for example, previously known from British patent no. 1,097,258 a system in which the load transfer arm 22 comprises an articulated part which normally lies below the sea surface and rests on the sea bed. The arm has buoyancy means, e.g. in the form of tanks, to enable the raising of the arm to the sea level when the system is
i virksomhet ved lasting eller lossing av et tankfartøy. Opp-drif tsmidlene sørger for en oppdriftskraft som er tilstrekkelig til at en del av armen heves til vannflaten. Oppdriftsmidlene i form av f.eks. oppdriftstanker eller lignende i tilknytning til lastoverføringsarmen, er en komplisert og kostbar konstruksjon og formålet med foreliggende oppfinnelse er i første rekke å komme frem til en enkel og hensiktsmessig utførelse sammenlignet med teknikkens stand. Med foreliggende oppfinnelse unngår man in business when loading or unloading a tanker. The buoyancy means provide a buoyancy force which is sufficient for a part of the arm to be raised to the surface of the water. The buoyancy funds in the form of e.g. buoyancy tanks or the like in connection with the load transfer arm, is a complicated and expensive construction and the purpose of the present invention is primarily to arrive at a simple and appropriate design compared to the state of the art. With the present invention, one avoids
faren for sammenvasing av slanger som er koblet mellom bøyen og lastsvivelen eller forankringen, og dette er oppnådd ved at det kobles en flytende del av lastledningen og den flytende del vil ligge i eller nær havflaten. Forøvrig er lastledningen forbundet direkte med lastsvivelen, hvorved undervanns-slangen og dennes forbindelse med lastsvivelen under tank-fartøyets kjøl reduserer muligheten for skader på de beskrevne komponenter. Oppfinnelsen er kjennetegnet ved de i kravene gjengitte trekk, og vil i det følgende bli forklart nærmere under henvisning til tegningen, som sett fra siden viser en ut-førelsesform for fortøynings- og lastesystemet i henhold til oppfinnelsen. the danger of entanglement of hoses connected between the buoy and the cargo swivel or the anchorage, and this is achieved by connecting a floating part of the cargo line and the floating part will lie in or near the sea surface. Otherwise, the cargo line is connected directly to the cargo swivel, whereby the underwater hose and its connection to the cargo swivel under the tank vessel's keel reduces the possibility of damage to the described components. The invention is characterized by the features reproduced in the claims, and will be explained in more detail below with reference to the drawing, which, viewed from the side, shows an embodiment of the mooring and loading system according to the invention.
Fortøynings- og lastesystemet omfatter et fortøy-ningsf undament 22, som er forankret på havbunnen og en svivel 24 som kan overføre aksiale krefter til en lastbærende sentral aksel 25. Fortøyningsbøyen 18 som på kjent måte kan ha van-lige fendere 41, er ved hjelp av en enkel fortøyning 20 forbundet med et øye 42 på toppen av svivelen. Når fortøynings-og lastesystemet settes på plass strammes fortøyningen 20 ved hjelp av en regulerbar spennanordning 4 3 som er festet til bøyen 18, slik at bøyen vil trekkes ned og ha et ganske lite fribord i stillestående vann. Fortøyningen 20 kan være en kabel, wire, kjetting eller lignende. Tankfartøyet fortøyes til bøyen ved hjelp av ikke viste trosser, fortrinnsvis i et fortøyningsøye 34 som befinner seg på bøyen. Undervannsrørled-ningen eller lastledningen 16 fører lasten frem til bøyen og er koblet til svivelhuset 24 i fortøyningsfundamentet 22, som vist med stiplede linjer på figuren. Væskesvivelhuset 24 er dreibart på sviveldelen 15 slik at bøyen 18 kan dreie seg i forhold til forankringsfundamentet 22. En lastledning 44 er i henhold.til oppfinnelsen svingbart tilknyttet svivelhuset ved hjelp av svivelskjøter 27. I henhold til oppfinnelsen er det til lasteledningen tilsluttet ytterligere ledninger, f.eks. slanger 45 tilkoblet enden av lastledningen 44 og de ledningsdeler som er koblet til lastledningen 44 strekker seg på skrå oppad og skal i henhold til oppfinnelsen flyte i eller nær ved havflaten. Ved en fordelaktig utførelsesform er de tilkoblede ledningsdeler slanger som strekker seg til havflaten med en The mooring and loading system comprises a mooring foundation 22, which is anchored to the seabed and a swivel 24 that can transfer axial forces to a load-carrying central axle 25. The mooring buoy 18, which in a known manner can have ordinary fenders 41, is by of a simple mooring 20 connected to an eye 42 at the top of the swivel. When the mooring and loading system is put in place, the mooring 20 is tightened by means of an adjustable tensioning device 4 3 which is attached to the buoy 18, so that the buoy will be pulled down and have a rather small freeboard in still water. The mooring 20 can be a cable, wire, chain or the like. The tanker is moored to the buoy using ropes not shown, preferably in a mooring eye 34 located on the buoy. The underwater pipeline or cargo line 16 carries the cargo to the buoy and is connected to the swivel housing 24 in the mooring foundation 22, as shown by dashed lines in the figure. The liquid swivel housing 24 is rotatable on the swivel part 15 so that the buoy 18 can rotate in relation to the anchoring foundation 22. According to the invention, a load line 44 is pivotably connected to the swivel housing by means of swivel joints 27. According to the invention, further lines are connected to the load line, e.g. hoses 45 connected to the end of the load line 44 and the line parts which are connected to the load line 44 extend at an angle upwards and according to the invention should float in or close to the sea surface. In an advantageous embodiment, the connected cable parts are hoses that extend to the sea surface with a
gradvis økende stigning. gradually increasing rise.
Ytterligere stabiliserende kabler, kjettinger eller wirer 31 med holdéanordriinger 46, er svingbart tilsluttet svivelhuset 24 på fortøyningsfundamentet. Dette sikrer at svivelhuset 24 og lastledningen 44 vil rotere sammen med bøyen 18 når vind og vær endrer beliggenheten av tankfartøyet. Om det er behov for det kan det anordnes ytterligere holdeanordninger 47 som holder kjettingene 31 i riktig stilling, d.v.s. i god avstand fra den sentrale forankring 20. Et anslag 48 er montert på undersiden av lastledningen 44 for å hindre denne i å svinge for langt ned. En ringformet anslagsskinne 49 som er festet til forankringsfundamentet 22, er anbragt slik at den vil hindre lastledningen i å svinge nedad, og dermed hindre led-ningen i å komme helt ned på fundamentet, slik at det kan opp-stå brudd. Additional stabilizing cables, chains or wires 31 with holding devices 46 are pivotably connected to the swivel housing 24 on the mooring foundation. This ensures that the swivel housing 24 and cargo line 44 will rotate together with the buoy 18 when wind and weather change the location of the tanker. If there is a need for it, additional holding devices 47 can be arranged which hold the chains 31 in the correct position, i.e. at a good distance from the central anchorage 20. A stop 48 is mounted on the underside of the load line 44 to prevent it from swinging too far down. An annular stop rail 49, which is attached to the anchoring foundation 22, is arranged so that it will prevent the load line from swinging downwards, and thus prevent the line from coming all the way down onto the foundation, so that breakage can occur.
