Description
Den foreliggende oppfinnelse vedrører respektive fremgangsmåter for låring og heving av en last til eller fra havbunnen, fra et fartøy som flyter på havoverflaten. The present invention relates to respective methods for lowering and raising a load to or from the seabed, from a vessel floating on the sea surface.
Denne beskrivelsen har til hensikt å beskrive en oppfinnelse vedrørende et installasjons- og løftekonsept som omfatter utstyr til ankerhåndteringsoperasjoner, samt en kran eller posisjoneringsvinsj for subsea operasjoner. This description is intended to describe an invention regarding an installation and lifting concept that includes equipment for anchor handling operations, as well as a crane or positioning winch for subsea operations.
Systemet er i utgangspunktet beskrevet installert på et ankerhåndteringsfartøy, men kan også tilpasses andre fartøyer, så som lektere, fraktefartøy, osv. Kjernen i oppfinnelsen er at en får mulighet til å håndtere en last med kran eller lignende som er mye større enn kranens løftekapasitet ved å benytte eksempelvis en ankerhåndteringsvinsj (lastholdevinsj) i konstant strekk modus, mens kranen kan operere i aktiv hiv modus. The system is basically described installed on an anchor handling vessel, but can also be adapted to other vessels, such as barges, cargo vessels, etc. The core of the invention is that you get the opportunity to handle a load with a crane or similar that is much larger than the crane's lifting capacity by to use, for example, an anchor handling winch (load holding winch) in constant tension mode, while the crane can operate in active heave mode.
Formålet med oppfinnelsen omfatter å benytte en av tromlene tilhørende anker-håndteringsvinsjen som lastholdevinsj, mens subseakranen/ posisjoneringsvinsjen posisjonerer lasten. The purpose of the invention includes using one of the drums belonging to the anchor handling winch as a load holding winch, while the subsea crane/positioning winch positions the load.
Dette oppnås ved at lasten henger i lastholdervinsjen enten over hekkrull eller gjennom overbord skivearrangement andre steder på fartøyet, for eksempel gjennom moon pool. Kranen/posisjoneringsvinsjen kan koples til hovedline ved hjelp av for eksempel en triangelplate. This is achieved by the load hanging in the load holder winch either over the stern roller or through an overboard sheave arrangement elsewhere on the vessel, for example through the moon pool. The crane/positioning winch can be connected to the main line using, for example, a triangular plate.
I følge oppfinnelsen frembringes en fremgangsmåte for låring av en last til havbunnen, fra et fartøy som flyter på havoverflaten, omfattende trekkene: According to the invention, a method is provided for lowering a load to the seabed, from a vessel floating on the sea surface, comprising the features:
- å koble en første løfteline fra en lastholdervinsj til lasten, - to connect a first lifting line from a load holder winch to the load,
- å koble en andre løfteline fra en posisjoneringsvinsj til lasten, og å justere posisjoneringsvinsjen slik at en vektandel av lasten opptas, - å sette lastholdervinsjen i konstant strekk modus og å justere lastholdervinsjen slik at en vektandel av lasten kompenseres, og - under låring av lasten slipper posisjoneringsvinsjen ut den andre løftelinen for senking av lasten, mens lastholdervinsjen følger etter med utslipp av den første løftelinen. - to connect a second lifting line from a positioning winch to the load, and to adjust the positioning winch so that a weight proportion of the load is taken up, - to set the load holding winch in constant tension mode and to adjust the load holding winch so that a weight proportion of the load is compensated, and - during loading of the load the positioning winch releases the second lifting line to lower the load, while the load holding winch follows by releasing the first lifting line.
I følge oppfinnelsen frembringes også en fremgangsmåte for heving av en last fra havbunnen, fra et fartøy som flyter på havoverflaten, omfattende trekkene: According to the invention, a method for raising a load from the seabed, from a vessel floating on the sea surface, is also produced, comprising the features:
- å koble en første løfteline fra en lastholdervinsj til lasten, - to connect a first lifting line from a load holder winch to the load,
- å koble en andre løfteline fra en posisjoneringsvinsj til lasten, - to connect a second lifting line from a positioning winch to the load,
- å sette posisjoneringsvinsjen i konstant strekk modus, og å justere posisjoneringsvinsjen slik at en vektandel av lasten opptas, - å sette lastholdervinsjen i konstant strekk modus, samt å justere lastholdervinsjen slik at en vektandel av lasten kompenseres, og - under heving av lasten løfter lastholdervinsjen lasten i konstant strekk modus og posisjoneringsvinsjen løfter lasten i konstant strekk modus. - to set the positioning winch in constant tension mode, and to adjust the positioning winch so that a proportion of the weight of the load is taken up, - to set the load holder winch in constant tension mode, and to adjust the load holder winch so that a proportion of the weight of the load is compensated, and - during lifting of the load, the load holder winch lifts the load in constant tension mode and the positioning winch lifts the load in constant tension mode.
Alternative utførelser er angitt i de uselvstendige kravene. Alternative designs are specified in the independent requirements.
Under både låring og heving kan vektandelen som lastholdervinsjen opptar være større enn vektandelen som posisjoneringsvinsjen opptar. During both lowering and lifting, the proportion of weight taken up by the load holding winch can be greater than the proportion of weight taken up by the positioning winch.
Under både låring og heving kan vektandelen som lastholdervinsjen opptar være over 80 % av lastens vekt, og vektandelen som posisjoneringsvinsjen opptar kan være under 20 % av lastens vekt. During both lowering and lifting, the proportion of weight taken up by the load holding winch can be over 80% of the load's weight, and the proportion of weight taken up by the positioning winch can be less than 20% of the load's weight.
Under både låring og heving kan vektandelen som lastholdervinsjen opptar være tilnærmet 90 % av lastens vekt, og vektandelen som posisjoneringsvinsjen opptar kan være tilnærmet 10 % av lastens vekt. During both lowering and lifting, the weight share that the load holder winch takes up can be approximately 90% of the load's weight, and the weight share that the positioning winch takes up can be approximately 10% of the load's weight.
Posisjoneringsvinsjen monteres fortrinnsvis til en dekkskran på fartøyet. The positioning winch is preferably mounted to a deck crane on the vessel.
Under landing av lasten på havbunnen kan dekkskranen settes i aktiv hiv kompenseringsmodus. During landing of the cargo on the seabed, the deck crane can be set in active heave compensation mode.
Under tilkobling av den andre løftelinen til lasten på havbunnen kan dekkskranen settes i aktiv hiv kompenseringsmodus. During connection of the second lifting line to the load on the seabed, the deck crane can be put into active heave compensation mode.
Oppfinnelsen skal nå beskrives nærmere ved hjelp av den vedlagte figuren, og som viser en skisse av et fartøy utstyrt med en kran og en vinsj. The invention will now be described in more detail with the help of the attached figure, which shows a sketch of a vessel equipped with a crane and a winch.
Som det fremgår fra figuren vises et fartøy 10, så som et ankerhåndteringsfartøy, og som er utstyrt med en lasthåndteringsvinsj 12, så som en ankerhåndteringsvinsj. Fartøyet 10 er videre utstyrt med en dekkskran 14 utstyrt med hivkompensering, og hvorpå, eller til, det er montert en posisjoneringsvinsj, indikert ved henvisningstall 14a, så som en vinsj for subsea operasjoner. As can be seen from the figure, a vessel 10 is shown, such as an anchor handling vessel, and which is equipped with a cargo handling winch 12, such as an anchor handling winch. The vessel 10 is further equipped with a deck crane 14 equipped with heave compensation, and on which, or to, a positioning winch, indicated by reference number 14a, such as a winch for subsea operations, is mounted.
Den hivkompensert kranen 14 kan i en utførelse eksempelvis omfatte en nedre vertikal bom og en øvre horisontal bom, som er innbyrdes forbundet via et ledd-stykke, og der den vertikale bommen nederst er forbundet med en sokkel som igjen omfatter en svingkrans for rotasjon av kranen om en vertikal akse. Et strekkstag kan være anordnet mellom sokkelen og leddstykket i en avstand fra den vertikale bommen og stort sett parallelt med denne i en normalposisjon for kranen. Den vertikale bommen kan drives av minst en sylinder og den øvre kranbommen sin bevegelse i forhold til den nedre bommen kan bli drevet av et mellomliggende sylinderarrangement, der sylinderarrangementet kan omfatte minst en enkelt-virkende sylinder og minst en dobbeltvirkende sylinder. Andre hivkompenserbare kraner kan selvfølgelig benyttes. The heave-compensated crane 14 can, in one embodiment, for example comprise a lower vertical boom and an upper horizontal boom, which are mutually connected via a joint piece, and where the vertical boom at the bottom is connected to a base which in turn comprises a slewing ring for rotation of the crane about a vertical axis. A tie rod can be arranged between the plinth and the joint piece at a distance from the vertical boom and largely parallel to this in a normal position for the crane. The vertical boom can be driven by at least one cylinder and the upper crane boom's movement in relation to the lower boom can be driven by an intermediate cylinder arrangement, where the cylinder arrangement can comprise at least one single-acting cylinder and at least one double-acting cylinder. Other heave-compensated cranes can of course be used.
Under heving og låring av en last 18 kan lasten være tilkoblet første og andre løfteliner 20, 22, der løftelinene for eksempel løper over fartøyets hekkrull, indikert ved henvisningstall 26, eller gjennom fartøyets moon pool 16. I sistnevnte tilfelle kan da løftelinen 20 løpe over en eller flere trinser 28 eller lignende montert på dekk, eller i moon poolen. During lifting and lowering of a load 18, the load can be connected to first and second lifting lines 20, 22, where the lifting lines for example run over the vessel's stern roller, indicated by reference number 26, or through the vessel's moon pool 16. In the latter case, the lifting line 20 can then run over one or more pulleys 28 or similar mounted on deck, or in the moon pool.
Den første løftelinen 20 løper fra lasthåndteringsvinsjen 12 og til lasten 18, og den andre løftelinen 22 løper fra posisjoneringsvinsjen 14a. Den første og den andre løftelinen kan være koblet til lasten 18 ved hjelp av for eksempel en triangelplate 24 eller lignende. The first lifting line 20 runs from the load handling winch 12 to the load 18, and the second lifting line 22 runs from the positioning winch 14a. The first and second lifting lines can be connected to the load 18 by means of, for example, a triangular plate 24 or the like.
Når kranen/posisjoneringsvinsjen er tilkoplet kan den løfte med ca. 10 % av objektets vekt. Deretter settes lastholdevinsjen i konstant strekk modus og justeres slik at ca. 90 % av vekten kompenseres. Kranen/posisjoneringsvinsjen kan nå benyttes til å styre lasten ned til havbunnen, mens lastholdevinsjen følger med. Ved landing på havbunnen kan kranen/posisjoneringsvinsjen settes til aktiv hiv kompenseringsmodus og lasten kan landes uten påvirkning av skipets bevegelser. When the crane/positioning winch is connected, it can lift by approx. 10% of the object's weight. The load holding winch is then set in constant tension mode and adjusted so that approx. 90% of the weight is compensated. The crane/positioning winch can now be used to guide the load down to the seabed, while the load holding winch is included. When landing on the seabed, the crane/positioning winch can be set to active heave compensation mode and the cargo can be landed without being affected by the ship's movements.
Ved løfting av objekt fra havbunnen benyttes kranen/posisjoneringsvinsjen til å holde løfteinnretning ved tilkopling, og om nødvendig i aktiv hiv kompenseringsmodus. Etter tilkopling kan kranen settes i konstant strekk, og lastholdevinsjen kan løfte lasten i konstant strekk modus fri av havbunnen. When lifting an object from the seabed, the crane/positioning winch is used to hold the lifting device when connected, and if necessary in active heave compensation mode. After connection, the crane can be set in constant tension, and the load holding winch can lift the load in constant tension mode free of the seabed.
