Den foreliggende oppfinnelse vedrører en anordning og en fremgangsmåte for sikker håndtering av fortøyninger egnet for et flytende eller nedsenkbart fartøy eller farkost i sjøen eller havet, som f.eks. egnet for oppdrettsanlegg, osv. Videre omhandler oppfinnelsen en anordning og en fremgangsmåte for dannelse og/eller betjening og/eller håndtering og/eller justering av en slakke eller lengde på et tau, slik som f.eks. et anker- eller fortøyningstau. The present invention relates to a device and a method for the safe handling of moorings suitable for a floating or submersible vessel or craft in the sea or ocean, such as e.g. suitable for breeding facilities, etc. Furthermore, the invention relates to a device and a method for forming and/or operating and/or handling and/or adjusting a slack or length of a rope, such as e.g. an anchor or mooring rope.

Hovedtrekkene ved oppfinnelsen fremgår av de selvstendige patentkrav. Ytterligere trekk ved oppfinnelsen er angitt i de uselvstendige krav. The main features of the invention appear from the independent patent claims. Further features of the invention are indicated in the independent claims.

Oppfinnelsen omhandler en tauhaler- eller twister-innretning som er egnet for bruk i en anordning for sikker håndtering av fortøyninger. Nevnte tauhaler- eller twister-innretning omfatter: et fundament som er egnet for festing til et dekk for et fartøy eller utgjør en del av dekket til fartøyet, The invention relates to a rope tailer or twister device which is suitable for use in a device for safe handling of moorings. Said rope tail or twister device includes: a foundation which is suitable for attachment to a deck of a vessel or forms part of the deck of the vessel,

en dreie- eller svingskive som er roterbart montert på fundamentet, og minst to frittløpende tauskiver eller sporskiver som er opplagret og roterbart montert på svingskiven. a turning or turning sheave that is rotatably mounted on the foundation, and at least two free-running rope sheaves or track sheaves that are stored and rotatably mounted on the turning sheave.

De frittløpende tauskiver eller sporskiver har respektive langsgående akser som kan være perpendikulære eller skråstilte til svingskivens plan. De langsgående akser kan være parallelle med svingskivens langsgående akse eller kan alternativt danne minst én vinkel med svingskivens langsgående akse, hvilken vinkel er forskjelling fra 0 grader. De langsgående akser kan ligge i svingskivens plan i en linje med svingskivens langsgående akse eller kan alternativt være i en konfigurasjon i svingskivens plan hvor linjen(e) som går gjennom sentrene for aksene i dette planet danner en annen plan-vinkel som er forskjellig fra en rett linje (dvs. forskjellig fra 180 grader). The free-running pulleys or track pulleys have respective longitudinal axes which can be perpendicular or inclined to the plane of the pulley. The longitudinal axes can be parallel to the longitudinal axis of the turntable or can alternatively form at least one angle with the longitudinal axis of the turntable, which angle is different from 0 degrees. The longitudinal axes may lie in the plane of the turntable in a line with the longitudinal axis of the turntable or alternatively may be in a configuration in the plane of the turntable where the line(s) passing through the centers of the axes in this plane form another plane angle which is different from a straight line (ie different from 180 degrees).

De frittløpende tauskiver eller sporskiver kan være anordnet i svingskivens periferiområde. Hver langsgående akse for den respektive frittløpende tauskive eller sporskive kan være anordnet i svingskivens plan med en forutbestemt avstand til svingskivens langsgående akse. De minst to avstandene for de minst to frittløpende tauskiver eller sporskiver kan være like eller ulike. The free-running rope pulleys or track pulleys can be arranged in the peripheral area of the turntable. Each longitudinal axis of the respective free-running pulley or track pulley can be arranged in the plane of the turntable with a predetermined distance to the longitudinal axis of the turntable. The at least two distances for the at least two free-running rope sheaves or track sheaves can be the same or different.

Tauhaler- eller twister-innretningen kan videre omfattende en høymoment driv-eller rotasjonsenhet som er montert mellom fundamentet og svingskiven. Denne rotasjonsenhet er anordnet for rotering av svingskiven. Videre kan rotasjonsenheten være en svingkrans med innebygget snekkedrift eller ett eller flere gir/ planetgir enten arrangert med direktekobling til svingskiven eller med moment-overføring via tannhjul. Rotasjonsenheten kan være egnet til å drives hydraulisk og/eller elektrisk. The rope tail or twister device can further comprise a high-torque drive or rotation unit which is mounted between the foundation and the turntable. This rotation unit is arranged for rotation of the turntable. Furthermore, the rotation unit can be a flywheel with built-in worm drive or one or more gears/planetary gears either arranged with direct connection to the flywheel or with torque transmission via gears. The rotation unit may be suitable to be driven hydraulically and/or electrically.

Denne tauhaler- eller twister-innretning kan være egnet for bruk i et oppdrettsanlegg. This rope tailer or twister device may be suitable for use in a fish farm.

Oppfinnelsen vedrører også en anordning for sikker håndtering av fortøyninger. Denne anordningen omfatter: The invention also relates to a device for safe handling of moorings. This device includes:

en taulås-innretning, og a rope lock device, and

en tauhaler- eller twister-innretning (6) ifølge oppfinnelsen. a rope tailer or twister device (6) according to the invention.

Taulås-innretningen omfatter to klem- eller spennbakker. Disse klem- eller spennbakkene er egnet til å presses mot hverandre for å holde og/eller låse et tau som løper mellom disse. Den ene spennbakken kan være fastmontert, slik som for eksempel fastmontert eller festet til en fundamentramme festet f.eks. til fartøyets dekk og/eller rekke. Den andre spennbakken kan være bevegelig og kan forskyves slik at tauet blir presset mellom spennbakkene for sikker låsing derav. Den bevegelige spennbakken kan betjenes av hydrauliske sylindere for oppnåelse av taulåsingen. Videre kan minst én av spennbakkene ha en bølge-formet kontaktflate mot tauet. I tillegg eller alternativt kan minst én av spennbakkene være leddet for bedre å tilpasse seg tauet sin struktur og derved øke kontaktflaten og gripeevnen mellom tauet og den respektive spennbakken. The rope lock device comprises two clamping or clamping jaws. These clamping or clamping jaws are suitable to be pressed against each other to hold and/or lock a rope running between them. The one clamping tray can be permanently mounted, such as, for example, permanently mounted or attached to a foundation frame attached, e.g. to the vessel's deck and/or row. The second clamping jaw can be movable and can be displaced so that the rope is pressed between the clamping jaws for secure locking thereof. The movable tension tray can be operated by hydraulic cylinders to achieve the rope locking. Furthermore, at least one of the clamping jaws can have a wave-shaped contact surface against the rope. In addition or alternatively, at least one of the clamping lugs can be articulated to better adapt to the rope's structure and thereby increase the contact surface and grip between the rope and the respective clamping lug.

Spennbakkenes kontaktflate mot tauet påføres et egnet eller passende friksjons-materiale/-belegg for derved å øke taulåsen sin holdekraft. A suitable or suitable friction material/coating is applied to the contact surface of the clamping jaws against the rope in order to thereby increase the holding power of the rope lock.

Anordningen kan videre omfatte tauholder-innretning. Tauholder-innretningen kan være egnet til å presse et tau ned i taulås-innretningen og til å sikre at tauet har riktig høyde inn på tauhaler- eller twister-innretningen (med de tilhørende frittløpende tauskiver). The device can also include a rope holder device. The rope holder device may be suitable for pressing a rope down into the rope lock device and to ensure that the rope is at the correct height onto the rope tail or twister device (with the associated free-running rope sheaves).

Anordningen kan være egnet for bruk i et oppdrettsanlegg. The device may be suitable for use in a breeding facility.

Oppfinnelsen angir til slutt en fremgangsmåte for sikker håndtering av fortøyninger. Fremgangsmåten omfatter: å føre et tau gjennom en taulås-innretning og en tauhaler- eller twister-innretning ifølge oppfinnelsen, The invention finally provides a method for the safe handling of moorings. The method comprises: passing a rope through a rope lock device and a rope tailer or twister device according to the invention,

å opparbeide en tau-slakke eller -lengde ved hjelp av rotasjon av en dreie-eller svingskive og minst to frittløpende tauskiver eller sporskiver opplagret og roterbart montert på svingskiven, to work up a rope slack or length by means of the rotation of a turning or turning sheave and at least two free-running rope sheaves or track sheaves supported and rotatably mounted on the turning sheave,

å låse tauet ved hjelp av taulås-innretningen. to lock the rope using the rope lock device.

Fremgangsmåten omfatter videre trinnet med: The method further comprises the step of:

å frigjøre tauet for derved å tillate håndtering og/eller justering av dette. Figur 1 illustrerer en anordning ifølge oppfinnelsen for låsing av tau kombinert med akkumulering av tau som etter låsing kan benyttes til å oppnå en tau-slakke på et tau. Figur 2 viser anordningen på figur 1, der en slakke er blitt halet inn og akkumulert. Figurer 3A-3B viser fra forskjellige sider en anordning for haling og akkumulering av en viss lengde av tau og som senere (etter låsing) kan benyttes til å oppnå en tau-slakke ifølge oppfinnelsen. to release the rope to thereby allow handling and/or adjustment thereof. Figure 1 illustrates a device according to the invention for locking ropes combined with accumulation of ropes which, after locking, can be used to achieve rope slack on a rope. Figure 2 shows the device in Figure 1, where a slack has been drawn in and accumulated. Figures 3A-3B show from different sides a device for hauling and accumulating a certain length of rope and which can later (after locking) be used to obtain a rope slack according to the invention.

I moderne havbruk knyttet til oppdrettsanlegg, er det ofte et antall oppdrettsnøter (merder) som er internt forbundet med et sinnrikt fortøyningssystem for å sikre interne faste posisjoner mellom merdene. I krysningspunktene mellom disse fortøyningene er hvert av tauene i hvert kryss forbundet via en felles koblingsplate eller -punkt / -sted (1) ved hjelp av minst én sjakkel (2). Se figur 1. In modern aquaculture linked to breeding facilities, there are often a number of breeding nets (cages) which are internally connected with an ingenious mooring system to ensure internal fixed positions between the cages. At the crossing points between these moorings, each of the ropes at each crossing is connected via a common connection plate or point / location (1) by means of at least one shackle (2). See Figure 1.

Ut fra minst én av disse koblingsplatene (1) går det også et ankertau (3) som ender i en ankerkjetting (ikke vist) som igjen er festet til et anker (ikke vist). Av ulike årsaker er det av og til behov for å justere lengden på tauet eller tauene. Disse tauene kan under slike operasjoner ha relativt høye belastninger. Strekk på f.eks. over 5 tonn er ikke uvanlig. I dag er denne oppgaven løst på forskjellige måter, og dette er operasjoner som har høy skadefrekvens og i de senere årene har det også forekommet alvorlige ulykker. From at least one of these connection plates (1) there is also an anchor rope (3) which ends in an anchor chain (not shown) which is in turn attached to an anchor (not shown). For various reasons, it is occasionally necessary to adjust the length of the rope or ropes. During such operations, these ropes can have relatively high loads. Stretch on e.g. over 5 tonnes is not unusual. Today, this task is solved in different ways, and these are operations that have a high frequency of injuries and in recent years, serious accidents have also occurred.

Denne oppfinnelsen er tenkt å bidra til en sikker arbeidsoperasjon, hvor én av hovedideene er å, i størst mulig grad, unngå behovet for manuelt arbeide i de kritiske fasene og på denne måten å unngå utsetting eller eksponering av mannskapet for unødig risiko. This invention is intended to contribute to a safe work operation, where one of the main ideas is to, to the greatest extent possible, avoid the need for manual work in the critical phases and in this way to avoid exposure or exposure of the crew to unnecessary risk.

Koblingsplaten (1) henger i en flytebøye (ikke vist) og er posisjonert flere meter under havoverflaten. En kran på båtdekket (ikke vist) løfter koblingsplaten (1) ut av sjøen og plasserer denne i en "koblingsplateholder" (4) på dekk. Denne koblingsplateholderen (4) fikserer og låser koblingsplaten (1) etter at det aktuelle tauet (3) som skal justeres, er plassert slik at det går gjennom en taulås-innretning (5) og en tauhaler- eller twister-innretning (6). Etter at koblingsplaten (1) er posisjonert og fiksert, ønsker en å frigjøre tauet som skal justeres. For å kunne gjøre dette, ønsker en å opparbeide en tau-slakke på, men ikke begrenset til, f.eks. ca. 1,0 - 5,0 meter, og spesielt f.eks. ca. 1,5 - 2,0 meter. Når denne (tau-)slakken er oppnådd, låses tauet ved babord rekke ved hjelp av en mulig eller valgfri tauholder-innretning (7) og taulås-innretningen (5). Slakken oppnås ved hjelp av en såkalt "twister" eller twister-innretning (6). Dette er en horisontal dreieskive (8) som kan være drevet eller rotert av en høymoment drivenhet (9). På denne dreieskiven (8) er det montert minst to frittløpende tauskiver eller sporskiver (10a, 10b). Tauskivene (10a, 10b) er opplagret og roterer derfor meget lett. The connecting plate (1) hangs in a floating buoy (not shown) and is positioned several meters below the sea surface. A crane on the boat deck (not shown) lifts the coupling plate (1) out of the sea and places it in a "coupling plate holder" (4) on deck. This coupling plate holder (4) fixes and locks the coupling plate (1) after the relevant rope (3) to be adjusted is positioned so that it passes through a rope lock device (5) and a rope tailer or twister device (6). After the coupling plate (1) has been positioned and fixed, one wants to release the rope to be adjusted. To be able to do this, one wants to work up a rope slack on, but not limited to, e.g. about. 1.0 - 5.0 metres, and especially e.g. about. 1.5 - 2.0 metres. When this (rope) slack has been achieved, the rope is locked on the port side using a possible or optional rope holder device (7) and the rope lock device (5). The slack is achieved using a so-called "twister" or twister device (6). This is a horizontal turntable (8) which can be driven or rotated by a high-torque drive unit (9). At least two free-running rope pulleys or track pulleys (10a, 10b) are mounted on this turntable (8). The rope pulleys (10a, 10b) are stored and therefore rotate very easily.

Før ankertauet legges inn over taulås-innretningen (5), tauholder-innretningen (7) og twister-innretningen (6), settes twister-innretningen (6) i posisjon med de to (-2-) frittløpende tauskivene (10a, 10b) på linje i langskips retning (for dette tilfellet). Se figur 1. Etter at tauet (3) er posisjonert og koblingsplaten (1) er posisjonert og fiksert, roteres twister-inretningen (6) f.eks. ca. 240 - 270 grader moturs (i dette tilfellet). Dette bevirker at ca. 1, - 2,0 meter tau hales inn og "akkumuleres" på twister-inretningen (6) i en "s"-form mellom de to (-2-) frittløpende tauskivene (10a, 10b). Se figur 2 som illustrerer dette. Den akkumulerte ekstra taulengden eller slakken kan frigjøres på dekk etter at taulås-innretningen (5) har sørget for sikker låsing av tauet (3). En brytskive (14a) hindrer slitasje (og/eller friksjon) av tauet (3) mot en fast(montert) klembakke (12b) i taulås-innretningen (5) under innhaling og akkumulering av en slakke på (det stramme) tauet (3). Taulås-innretningen (5) omfatter en fast(montert) klembakke (12b) og en bevegelig klembakke (12a). Taulås-innretningen (5) omfatter videre hydraulikksylindere (11) for betjening av den bevegelige klembakken (12a) for derved å kunne oppnå taulåsingen. Before the anchor rope is laid over the rope lock device (5), the rope holder device (7) and the twister device (6), the twister device (6) is set in position with the two (-2-) free-running rope sheaves (10a, 10b) in line in the longship direction (for this case). See figure 1. After the rope (3) has been positioned and the coupling plate (1) has been positioned and fixed, the twister device (6) is rotated, e.g. about. 240 - 270 degrees counterclockwise (in this case). This means that approx. 1 - 2.0 meters of rope are hauled in and "accumulated" on the twister device (6) in an "s" shape between the two (-2-) free-running rope sheaves (10a, 10b). See figure 2 which illustrates this. The accumulated extra rope length or slack can be released on deck after the rope lock device (5) has ensured safe locking of the rope (3). A break washer (14a) prevents wear (and/or friction) of the rope (3) against a fixed (mounted) clamping jaw (12b) in the rope lock device (5) during hauling in and accumulation of slack on the (tight) rope (3 ). The rope lock device (5) comprises a fixed (mounted) clamping jaw (12b) and a movable clamping jaw (12a). The rope lock device (5) further comprises hydraulic cylinders (11) for operating the movable clamping tray (12a) in order to thereby be able to achieve rope locking.

Før hydraulikksylindrene (11) i taulås-innretningen (5) kjører fram den bevegelige klembakken (12a), roterer en sylinder-innretning (13) tauholder-innretningen (7) og presser tauet (3) ved hjelp av en arm (20) ned i taulås-innretningen (5) og blir stående som sikkerhet mot at tauet (3) dras ut av klembakkene (12a, 12b). Before the hydraulic cylinders (11) in the rope lock device (5) advance the movable clamp tray (12a), a cylinder device (13) rotates the rope holder device (7) and presses the rope (3) down with the help of an arm (20) in the rope lock device (5) and remains as security against the rope (3) being pulled out of the clamping jaws (12a, 12b).

Den bevegelige klembakken (12a) kjøres fram, klemmer tauet (3) mot den faste klembakken (12b) og sikrer således tauet (3) fra å gli i taulås-innretningen (5). The movable clamp tray (12a) is driven forward, clamps the rope (3) against the fixed clamp tray (12b) and thus secures the rope (3) from slipping in the rope lock device (5).

Etter at taulås-innretningen (5) har låst tauet (3), roteres twister-innretningen (6) i retur (medurs i dette tilfellet) til utgangspunktet. Nå har (anker)tauet (3) en slakke tilsvarende, men ikke begrenset til, f.eks. ca. 1,5 - 2,0 meter og kan enkelt kobles fra koblingsplaten (1) ved å løsne sjakkelen (2). After the rope lock device (5) has locked the rope (3), the twister device (6) is rotated back (clockwise in this case) to the starting point. Now the (anchor) rope (3) has a slack corresponding to, but not limited to, e.g. about. 1.5 - 2.0 meters and can be easily disconnected from the connection plate (1) by loosening the shackle (2).

Den frie tauenden (3) fra koblingsplaten (1) kan nå kobles via egen brytskive (14b) til vinsjen (ikke vist) plassert framme på arbeidsdekket. Med vinsjen strammes så ankertauet (3) opp. Tauholder-innretningen (7) og taulås-innretningen (5) åpnes deretter. Ankertauet (3) justeres deretter til riktig stramming / lengde ved hjelp av vinsjen. Tauholder-innretningen (7) og taulås-innretningen (5) kjøres i lås-posisjon igjen. Vinsjen slakkes opp og tauet (3) kappes og spleises med en ny kause (15). Lengden på tauet (3) må beregnes slik at slakken etter ny montering i koblingsplaten (1) blir mindre enn twister-innretningen (6) sin "akkumuleringsevne". The free rope end (3) from the coupling plate (1) can now be connected via its own breaker disc (14b) to the winch (not shown) located at the front of the working deck. The anchor rope (3) is then tightened with the winch. The rope holder device (7) and the rope lock device (5) are then opened. The anchor rope (3) is then adjusted to the correct tension / length using the winch. The rope holder device (7) and the rope lock device (5) are driven into the locked position again. The winch is loosened and the rope (3) is cut and spliced with a new cable (15). The length of the rope (3) must be calculated so that the slack after reassembly in the coupling plate (1) is less than the "accumulation capacity" of the twister device (6).

Etter at tauet (3) på nytt er montert i koblingsplaten (1), roteres twister-innretningen (6) moturs (i dette tilfellet), akkumulerer slakken i tauet (3) og gjenskaper tilnærmet normalt strekk i ankertauet (3) mellom koblingsplaten (1) og taulås-innretningen (5). Tauholder-innretningen (7) og taulås-innretninen (5) åpnes. Twister-innretningen (6) roterer deretter medurs (i dette tilfellet) tilbake til sin opprinnelige posisjon med de to (-2-) frittløpende tauskivene (10a, 10b) på linje i båtens lengderetning (i dette tilfellet). Koblingsplaten (1) tar nå alle tau krefter og er nå klar for utløfting. Dekkskran (ikke vist) løfter koblingsplaten (1) ut av koblingsplateholderen (4) og så høyt at ankertauet (3) kommer ut av twister-innretningen (6) og taulås-innretningen (5) og kan således frigjøres fra båten. After the rope (3) is reassembled in the connecting plate (1), the twister device (6) is rotated counterclockwise (in this case), accumulating the slack in the rope (3) and recreating approximately normal tension in the anchor rope (3) between the connecting plate ( 1) and the rope lock device (5). The rope holder device (7) and the rope lock device (5) are opened. The twister device (6) then rotates clockwise (in this case) back to its original position with the two (-2-) free-running rope sheaves (10a, 10b) aligned in the longitudinal direction of the boat (in this case). The coupling plate (1) now takes all the rope forces and is now ready for lifting. The deck crane (not shown) lifts the coupling plate (1) out of the coupling plate holder (4) and so high that the anchor rope (3) comes out of the twister device (6) and the rope lock device (5) and can thus be released from the boat.

Taulås-innretningen (5) kan være bygd på en egen ramme (16) som er festet til båtdekket og/eller båtrekka (17). Låsen består av en fastmontert klembakke (12b) og en hydraulisk drevet klembakke (12a). Disse to (-2-) klembakkene (12a, 12b) kan ha en bølgeprofil og en overflatestruktur som gir god gripeevne. En eller begge klembakkene (12a, 12b) kan gjøres leddet (18) (for eksempel 3-delt) for lettere å tilpasse klembakkene (12a, 12b) til tauet (3) sin struktur. The rope lock device (5) can be built on a separate frame (16) which is attached to the boat deck and/or boat rack (17). The lock consists of a fixed clamping jaw (12b) and a hydraulically driven clamping jaw (12a). These two (-2-) clamping jaws (12a, 12b) can have a wave profile and a surface structure that provides good grip. One or both clamping jaws (12a, 12b) can be made articulated (18) (for example 3-part) to more easily adapt the clamping jaws (12a, 12b) to the structure of the rope (3).

Tauholder-innretningen (7) består av et lagret boss (19) hvor det kan være sveiset en buet stålaksel eller arm (20). Tauholder-innretningen (7) kan ved hjelp av en egen hydraulikksylinder (13) svinge bosset (19) med stålakselen / armen (20) slik at tauholder-innretningen (7) kan gå fra åpen til lukket posisjon. Tauholder-innretningen (7) kan være montert på rammen (16) for taulås-innretningen (5). The rope holder device (7) consists of a stored boss (19) to which a curved steel shaft or arm (20) may be welded. The rope holder device (7) can, with the help of a separate hydraulic cylinder (13), swing the boss (19) with the steel shaft / arm (20) so that the rope holder device (7) can go from open to closed position. The rope holder device (7) can be mounted on the frame (16) for the rope lock device (5).

Både taulås-innretningen (5) og tauholder-innretningen (7) kan fjernstyres elektrohydraulisk og kan betjenes fra operatørpanel i styrhus / kontrollrom eller fra annen fjernstyring / radiostyring. Both the rope lock device (5) and the rope holder device (7) can be remotely controlled electro-hydraulic and can be operated from the operator's panel in the wheelhouse / control room or from other remote control / radio control.

Twister-innretningen (6) består av et kraftig fundament (21) festet i båtdekket. På toppen av dette fundamentet (21) monteres en høymoment rotasjonsenhet (9). Dette kan være en svingkrans (9) med innebygget snekkedrift (22) (som vist på figur 3A og/eller 3B) eller f.eks. et veldimensjonert planetgir- / gir-arrangement. Drift kan være hydraulisk (23) eller elektrisk. The Twister device (6) consists of a strong foundation (21) fixed in the boat deck. A high-torque rotation unit (9) is mounted on top of this foundation (21). This can be a slewing ring (9) with built-in worm drive (22) (as shown in figure 3A and/or 3B) or e.g. a well-sized planetary gear / gear arrangement. Operation can be hydraulic (23) or electric.

På toppen av rotasjonsenheten (9) er det montert en svingskive (8) som igjen har minst to frittløpende tauskiver (10a, 10b) på toppen. Disse skivene er opplagret slik at de løper lett. Som en kan se fra figur 3B, ligger de langsgående akser (10La, 10Lb) (dvs. sentrene for tauskivene (10a, 10b) i nevnte plan) i svingskivens (8) plan i en linje (L) med svingskivens (8) langsgående akse (8L) On the top of the rotation unit (9) a turntable (8) is mounted, which in turn has at least two free-running pulleys (10a, 10b) on top. These discs are stored so that they run easily. As can be seen from Figure 3B, the longitudinal axes (10La, 10Lb) (i.e. the centers of the pulleys (10a, 10b) in said plane) lie in the plane of the turntable (8) in a line (L) with the longitudinal of the turntable (8) axle (8L)

(dvs. senteret for svingskiven (8) i nevnte plan). Alternativt kan de langsgående akser (10La, 10Lb) ligge i en konfigurasjon i svingskivens (8) plan, hvor linjen (L; dvs. de to linjer 10La-8L og 8L-10Lb) som går gjennom aksene (10La, 8L, (i.e. the center of the swash plate (8) in the aforementioned plan). Alternatively, the longitudinal axes (10La, 10Lb) can lie in a configuration in the plane of the turntable (8), where the line (L; i.e. the two lines 10La-8L and 8L-10Lb) passing through the axes (10La, 8L,

lOLb) eller sentrene for tauskivene (10a, 10b) i planet, danner en plan-vinkel som er forskjellig fra en rett linje (dvs. 180 grader) (se linje (L) på figur 3B). lOLb) or the centers of the sheaves (10a, 10b) in the plane, form a plane angle different from a straight line (ie 180 degrees) (see line (L) in Figure 3B).

Som vist på figur 3A har de frittløpende tauskiver eller sporskiver (10a, 10b) respektive langsgående akser (lOLa, lOLb) som er perpendikulære til svingskivens (8) plan. Alternativt kan de langsgående akser (lOLa, lOLb) være skråstilte til svingskivens (8) plan. Figur 3A viser også at de langsgående akser (lOLa, lOLb) er parallelle med svingskivens (8) langsgående akse (8L). Alternativt kan de langsgående akser (lOLa, lOLb) danne minst én vinkel (V; VI, V2) med svingskivens (8) langsgående akse (8L). Denne vinkelen (V; VI, V2) vil i dette tilfellet være forskjelling fra 0 grader. As shown in Figure 3A, the free-running pulleys or track pulleys (10a, 10b) have respective longitudinal axes (1OLa, 1OLb) which are perpendicular to the plane of the turntable (8). Alternatively, the longitudinal axes (lOLa, lOLb) can be inclined to the plane of the turntable (8). Figure 3A also shows that the longitudinal axes (1OLa, 1OLb) are parallel to the longitudinal axis (8L) of the turntable (8). Alternatively, the longitudinal axes (1OLa, 1OLb) can form at least one angle (V; VI, V2) with the longitudinal axis (8L) of the turntable (8). This angle (V; VI, V2) will in this case be different from 0 degrees.

The twister device (6) can be operated electro-hydraulically or purely electrically and can be controlled remotely from the control panel in the wheelhouse or from/with the help of (via) other remote control/radio control.

Tauhaler- eller twister-innretningen (6) kan, etter modifisering av lengden på tauet (3), akkumulere den eksisterende slakke og forspenne tauet (3) på en slik måte at frigjøring av taulås-innretningen (5) og tauholder-innretningen (7) kan skje på en sikker og kontrollert måte. The rope tailer or twister device (6) can, after modifying the length of the rope (3), accumulate the existing slack and pretension the rope (3) in such a way that the release of the rope lock device (5) and the rope holder device (7) ) can happen in a safe and controlled way.

Taulås-innretningen (5), tauholder-innretningen (7) og tauhaler- eller twister-innretningen (6) er alle egnet for sikker løsing og festing av tauet (3) mot koblingsplaten eller -punktet (1). The rope lock device (5), the rope holder device (7) and the rope tail or twister device (6) are all suitable for safely releasing and securing the rope (3) against the connection plate or point (1).

De andre komponentene i dekksutrustningen slik som koblingsplateholderen (4), brytskiven (14b) mot vinsjen, vinsjen og dekkskranen er nødvendig utrustning for totalfunksjonen, men er ikke de aller viktigste elementene her. The other components of the deck equipment, such as the coupling plate holder (4), the breaker disc (14b) against the winch, the winch and the deck crane are necessary equipment for the overall function, but are not the most important elements here.
