Description
Den foreliggende oppfinnelse vedrører en anordning og fremgangsmåte ved vinsj, som respektivt angitt i ingressen til de selvstendige kravene 1 og 5. The present invention relates to a device and method for a winch, as respectively stated in the preamble to the independent claims 1 and 5.
Ved tidligere kjente løsninger trekkes stigerør (risere) opp fra undervannsinnstallasjoner til innfesting på oljeplattformer ved hjelp av fast monterte vinsjer som ved hjelp av blokker og bryteskiver ledes til punktet for opptrekk av den aktuelle riser. Dette legger beslag på store arealer på dekk, og medfører risiki ved oppstramming og eventuelle brudd på ståltau. Når stigerør skal plasseres i sitt tiltenkte opphengspunkt må løfteviren styres ved hjelp av andre vinsjer (tuggervinsjer) for posisjonering før nedesenking til låsepunktet. På samme måte som for løftevinsjen vil inntrekk ved de forskjellige låsepunkter medføre fare ved bruk av blokker og bryteskiver. With previously known solutions, risers (risers) are pulled up from underwater installations to be attached to oil platforms by means of permanently mounted winches which, with the help of blocks and breaker discs, are guided to the point for pulling up the relevant riser. This seizes large areas of the deck, and entails risks during tightening and possible breaks in the steel ropes. When risers are to be placed in their intended suspension point, the lifting wire must be controlled with the help of other winches (chewing winches) for positioning before lowering to the locking point. In the same way as for the lifting winch, pulling in at the various locking points will cause danger when using blocks and breaker discs.
Ved oppkopling av stigerøret benytter tidligere kjente løsninger således en vinsj for å trekke stigerøret opp til innfestingspunktet på riggen. Når tilstekkelig høyde/posisjon er oppnådd bringes stigerøret således inn til posisjon for innfesting og oppkopling, og denne inntrekkingen blir vanligvis utført ved hjelp av vinsjer som trekker løfteviren inn til festeposisjonen. Denne operasjonen medfører således stor risiko for skader på materiell og betjening, og krever ekstra bemanning. When connecting the riser, previously known solutions thus use a winch to pull the riser up to the attachment point on the rig. When a suitable height/position has been achieved, the riser is thus brought into position for attachment and connection, and this retraction is usually carried out using winches that pull the lifting wire into the attachment position. This operation therefore carries a high risk of damage to equipment and operation, and requires additional staffing.
Av relatert tidligere kjent teknikk kan nevnes GB 798995, CH 200294, CA 988501 og, uten at noen av disse publikasjonene angir vinsjer eller anordninger med vinsjer for inntrekking av horosintal posisjonering av stigerør. Of related prior art can be mentioned GB 798995, CH 200294, CA 988501 and, without any of these publications specifying winches or devices with winches for retracting horizontal positioning of risers.
De ovenenevnte problemer eller mangler søkes i henhold til oppfinnelsen løst, og de ovenevnte risiki redusert eller eliminert, med en anordning og fremgangsmåte som respektivt angitt i karakteristikken til de selvstendige kravene 1 og 5. According to the invention, the above-mentioned problems or deficiencies are sought to be solved, and the above-mentioned risks reduced or eliminated, with a device and method as respectively stated in the characteristics of the independent claims 1 and 5.
Fordelaktige utførelsesformer av oppfinnelsen fremgår av de uselvstendige kravene. Advantageous embodiments of the invention appear from the independent claims.
Oppfinnelsen er nærmere beskrevet nedenfor, med henvisning til de medfølgende tegninger der: Figur la og lb viser en første utførelsesform av anordningen i henhold til oppfinnelsen i to ulike posisjoner, og The invention is described in more detail below, with reference to the accompanying drawings where: Figures la and lb show a first embodiment of the device according to the invention in two different positions, and
Figur 2 viser en andre utførelsesform av anordningen i henhold til oppfinnelsen. Figure 2 shows a second embodiment of the device according to the invention.
Ved først å henvise til figurene la og lb er det på en innstallasjon 1, for eksempel en oljeplattform eller et riggfartøy, tilveiebrakt en vinsj 2 for forflytning sideveis til et aktuelt punkt for inntrekking av et (ikke vist) stigerør hengende i en vaier 3 med påmontert låsekile 4. Når vaieren 3 med stigerøret er løftet til nødvendig høyde (posisjonen vist i figur la), finjusteres det over et aktuelt låsepunkt 5 med et låsesete ved ny sideveis forflyttning til eksakt posisjon. Deretter trekkes vaieren 3 med stigerøret inn til låsepunktet 5 (posisjonen vist i figur lb), før det senkes ned til låsende anlegg i låsepunktet 5 med kilen 4 beliggende i låsesetet. Inntrekkingen besørges av en manipulatorarm 6 med tilstrekkelig kraft til å posisjonere stigerøret til låsepunktet 5 før nedsenking i låsesetet. By first referring to figures la and lb, on an installation 1, for example an oil platform or a rig vessel, a winch 2 is provided for movement laterally to a relevant point for retracting a riser pipe (not shown) hanging in a cable 3 with mounted locking wedge 4. When the wire 3 with the riser has been raised to the required height (the position shown in figure la), it is fine-tuned over a relevant locking point 5 with a locking seat by new lateral movement to the exact position. Then the wire 3 with the riser is pulled in to the locking point 5 (the position shown in figure 1b), before it is lowered to the locking device in the locking point 5 with the wedge 4 situated in the locking seat. The retraction is provided by a manipulator arm 6 with sufficient force to position the riser to the locking point 5 before immersion in the locking seat.
Manipulatorarmen 6 kontrollerer vinsjvaierens 3 posisjon, og hindrer utilsiktet bevegelse. Armen 6 er festet til vinsjen 2, og dimensjonert for å trekke vaieren 3 inn til riktig innfestingsposisjon etter at tilstrekkelig høyde er oppnådd, som nevnt ovenfor. The manipulator arm 6 controls the position of the winch cable 3, and prevents unintentional movement. The arm 6 is attached to the winch 2, and dimensioned to pull the wire 3 in to the correct attachment position after sufficient height has been achieved, as mentioned above.
Vinsjvaieren 3 kjøres først til riktig høyde for innfesting/låsing. Manipulatorarmen 6 flyttes så sidelengs i horisontalplanet og bringer stigerøret til riktig posisjon for innfesting/låsing. Deretter trekker armen 6 stigerøret inn til låsepunktet 5, som antydet med pil i figur lb. The winch cable 3 is first run to the correct height for fixing/locking. The manipulator arm 6 is then moved sideways in the horizontal plane and brings the riser to the correct position for fixing/locking. The arm 6 then pulls the riser in to the locking point 5, as indicated by the arrow in figure 1b.
Manipulatorarmen 6 styrer fordelaktig også spolingen av vaieren 3 på trommelen til vinsjen under inn- og utkjøring av vinsjvaier 3. Armens 6 bevegelser foretas fortrinnsvis ved at en eller flere hydrauliske sylindre 7 kjøres til ønsket kraft og posisjon. I stedet for hydrauliske sylindre 7 kan andre aktuatorer, som for eksempel elektriske eller pneumatiske, tenkes benyttet. The manipulator arm 6 advantageously also controls the winding of the wire 3 on the drum of the winch during the entry and exit of the winch wire 3. The movements of the arm 6 are preferably made by driving one or more hydraulic cylinders 7 to the desired force and position. Instead of hydraulic cylinders 7, other actuators, such as electric or pneumatic ones, can be used.
Manipulatorarmen 6 vist i figurene la og lb innbefatter et parallellogramledd 8 hvor det mellom to diagonale leddpunkter er anordnet en hydraulisk sylinder 7. Til en ende av manipulatorarmen 6 er det tilordnet to løpehjul 9 for leding av vaieren 3. The manipulator arm 6 shown in figures la and lb includes a parallelogram joint 8 where a hydraulic cylinder 7 is arranged between two diagonal joint points. To one end of the manipulator arm 6 two idler wheels 9 are assigned for guiding the wire 3.
I figur 2 er det vist en alternativ utforming av manipulatorarmen 6 idet denne er i det vesentlige U-formet og opplagret i vinsjen 2 i begge ender av U'en. Mellom to festepunkter på vinsjen 2 og to festeører 10 i en avstand fra hver ende av U'en er det anordnet to hydrauliske sylindere 7. Sentralt i U'en er det anordnet et løpehjul 9 for leding av vinsjvaieren 3. Figure 2 shows an alternative design of the manipulator arm 6 in that it is essentially U-shaped and stored in the winch 2 at both ends of the U. Between two attachment points on the winch 2 and two attachment ears 10 at a distance from each end of the U, two hydraulic cylinders 7 are arranged. In the center of the U, an idler wheel 9 is arranged for guiding the winch cable 3.
Manipulatorarmen 6 kan i tillegg utstyres med en mindre (ikke vist) vinsj for riggehjelp og inntrekking av ståltau fra hjelpefartøyer. Ved å benytte manipulatorarmen 6 til dette formålet oppnås en effektiv håndtering av hjelpeutrustning ved montasje av stigerør. The manipulator arm 6 can also be equipped with a smaller (not shown) winch for rigging assistance and pulling in steel ropes from auxiliary vessels. By using the manipulator arm 6 for this purpose, efficient handling of auxiliary equipment is achieved when mounting risers.
