Description
SPOOLING DEVICE AND VESSEL COMPRISING THE SPOOLING DEVICE
The present disclosure pertains to the field of mooring of vessels. The present disclosure relates to a spooling device for line handling on a vessel, and a vessel comprising the line handling device.
BACKGROUND
Mooring refers to an act of securing a vessel to a permanent structure, which permanent structure will hereinafter be referred to as a mooring point. A vessel may be secured to a mooring point to forestall free movement of the vessel on the water. An anchor mooring fixes the vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore.
The mooring point may be any variety of shore fixture from trees and rocks to specially constructed areas such as quays, wharfs, jetties, piers, anchor buoys, and/or mooring buoys.
Mooring is often accomplished using thick ropes called mooring lines or hawsers. The lines may be fixed to deck fittings on the vessel at one end and to fittings such as bollards, rings, and cleats at the other end.
Mooring typically requires cooperation between people on shore and on a vessel. Heavy mooring lines are often passed from larger vessels to people on shore by smaller, weighted heaving lines, which may also be referred to as messenger lines. The smaller heaving lines may be connected to an eyelet of the mooring lines, which eyelet may be used to attach the mooring line to a mooring point. The mooring line is then pulled onto shore by means of the heaving line and are then manually connected to the mooring point by the people on shore.
Typically, a plurality of mooring lines is required to secure a vessel. The heaviest cargo ships may require more than a dozen mooring lines, while small vessels can generally be moored by two to six mooring lines.
Once a mooring line is attached to a mooring point, it is pulled tight. Large ships generally tighten their mooring lines using heavy machinery, such as mooring winches or capstans.

Typically, a plurality of mooring lines is required to secure a vessel. The heaviest cargo ships may require more than a dozen mooring lines, while small vessels can generally be moored by two to six mooring lines.
Once a mooring line is attached to a mooring point, it is pulled tight. Large ships generally tighten their mooring lines using heavy machinery, such as mooring winches or capstans.
2 The high tension may cause snap-back of the mooring line. A snap-back is a sudden recoil of a mooring line as a result of its failure under tension. A failed mooring line could recoil with great velocity, possibly resulting in injury or even death to personnel handling the mooring line onboard the vessel or on shore. The risk of snap-back increases if the mooring line are worn or damaged.
Mooring lines are typically long and heavy ropes stored on board ships in coil form, such as e.g., spooled onto a drum of a winch, such as a mooring winch. When these lines are under operation, they tend to naturally form a coil or ring shape, which is also known as rope bight. If a person involved in mooring operation comes under this rope bight, such as gets stuck in a coil or ring of the line, a pull of the line may drag the person over the ship or smash the person against the vessel or equipment mounted or stored on the vessel.
The heaving lines are typically spooled onto the drum of the mooring winch on top of the mooring line. However, since the heaving lines are generally much smaller than the mooring line, the heaving line may slide between and get stuck in between two wraps, such as between two coils, of the winded mooring line. This may e.g., be the case if the heaving line is pulled hard, such as if an eyelet of the mooring line, to which the heaving line is attached, slides of the drum and pulls the heaving line with it. As a consequence, the heaving line may, during an unwinding procedure, be stuck on the drum of the mooring winch and not unwind properly. The heaving line may, instead of releasing from the drum, follow a rotation of the drum and start to wind onto the drum again.
If the messenger line suddenly starts to wind onto the drum during an unwinding procedure, a heavy pull or wrench may be caused on the heaving line which may cause a person handling the messenger line to fall over, be dragged over the ship or over an edge of a quay or may be smashed against the vessel or equipment mounted or stored on the vessel, which may in turn lead to severe injuries or even death. This presents a danger to personnel handling the spooling device and the messenger line.
Snap-back, rope bight and sudden heavy pulls on the heaving line may lead to severe injuries or even death of personnel. Hence, mooring of a vessel involves hard labor with risk for injuries for personnel handling the mooring line. Further, mooring operations are time consuming and must be planned in advance to ensure that people are available onshore to assist during mooring.

3 SUMMARY
Accordingly, there is a need for a spooling device for handling a line, such as a mooring line and/or a messenger line, which mitigate, alleviate or address the shortcomings existing and provide a safe spooling operation.
A spooling device for line handling on a vessel is disclosed. The spooling device comprises a main drum for spooling of a main line, such as a mooring line, a towing line or a hawser. The main drum is configured to rotate around a longitudinal center axis and is configured to wind and/or unwind the main line in a spooling direction. The spooling device comprises an auxiliary drum for spooling of an auxiliary line (such as a messenger line or a heaving line) connected to a distal end of the main line. The spooling device further comprises a guiding arm being movably arranged in relation to the main drum and the auxiliary drum at a distance from the longitudinal center axis in the spooling direction.
The guiding arm being configured to perform a sweeping movement in relation to the main drum, such that the guiding arm is configured to guide the auxiliary line onto the auxiliary drum during a spooling procedure.
Further, a vessel comprising the spooling device is disclosed.
It is an advantage of the present disclosure that the safety of a mooring procedure is improved, since the spooling device reduces the risk of sudden pulls on the auxiliary line during a spooling procedure. Furthermore, since the auxiliary line is not stored on top of the main line, wear on the main line may be reduced, which reduces the risk of snap-back of the main line during a mooring or spooling procedure.
Furthermore, the risk of the auxiliary line getting stuck in the main line is reduced, thereby allowing the spooling device to be autonomously operated, since no manual labor is required to free a stuck auxiliary line. The spooling device according to the present disclosure may thus also be autonomously operated, such as being comprised on an autonomous vessel, which increases efficiency of the mooring or spooling procedure and reduces the need of personnel being on deck to oversee and handle the spooling procedure.
Thereby, the risk of personnel getting injured is reduced. Thus, a safe mooring operation is provided.

A spooling device for line handling on a vessel is disclosed. The spooling device comprises a main drum for spooling of a main line (such as a mooring line, a towing line or a hawser), wherein the main drum is configured to rotate around a longitudinal center axis, such as a first longitudinal center axis. The main drum is configured to wind and/or unwind the main line in a spooling direction. The spooling device comprises an auxiliary drum for spooling of an auxiliary line (such as a messenger line or a heaving line) connected to a distal end of the main line. The auxiliary drum may be a separate drum or may be a section, such as an end section, of the main drum. The spooling device further comprises a guiding arm being movably arranged in relation to the main drum and the auxiliary drum at a distance from the longitudinal center axis in the spooling direction. The guiding arm is configured to perform a sweeping movement in relation to the main drum, such that the guiding arm is configured to guide the auxiliary line onto the auxiliary drum during a spooling procedure. The part of the spooling procedure during which the main line is winded onto the main drum may herein be referred to as a main spooling procedure and the part of the spooling procedure during which the auxiliary line is winded onto the auxiliary drum may herein be referred to as an auxiliary spooling procedure.
The spooling direction shall herein be interpreted as the direction in which a line, such as the main line and/or auxiliary line leaves a drum, such as the main drum and/or the auxiliary drum. The spooling direction may be substantially perpendicular to the longitudinal center axis of the drum. Substantially perpendicular shall herein be understood as the spooling direction being directed at an angle in the range of 85-900 to the longitudinal center axis of the drum.
The auxiliary drum may be arranged side-by-side with the main drum. The auxiliary drum may rotate around a second longitudinal center axis. The second longitudinal center axis may be arranged in parallel with the longitudinal center axis of the main drum, such as the
6 first longitudinal center axis. In one or more embodiments of the spooling device the auxiliary drum may be arranged coaxially with the main drum. In other words, the second longitudinal center axis of the auxiliary drum may be coaxially arranged with the rotation axis of the main drum.
The main drum may comprise a first and a second flange arranged on the longitudinal ends of the main drum, wherein the auxiliary drum is arranged on the first flange of the main drum. The first and second flanges of the main drum, which may also be referred to as a first and second main flange, may define side walls providing lateral support to the main line when the main line is stored on the main drum. The main drum may further comprise a barrel, which may be referred to as a main barrel for receiving the main line.
The main barrel may be coaxially arranged with the first and the second flange and may be located between the first and the second main flange. A diameter of the main barrel may be smaller than a diameter of the first and second main flanges.
In some exemplary spooling devices, the auxiliary drum may be comprised in the main drum, such that a section of the main drum, such as an end section close to a flange of the main drum (such as the second main flange) forms the auxiliary drum.
In some exemplary spooling devices, the auxiliary drum may also comprise a first and a second flange, which may be referred to as a first and a second auxiliary flange, and a barrel, which may be referred to as an auxiliary barrel. The auxiliary barrel may be arranged between the first and second auxiliary flange. A diameter of the auxiliary barrel may be smaller than a diameter of the first and second auxiliary flanges. The diameter of the auxiliary barrel may be different to the diameter of the main barrel. The main barrel and the auxiliary barrel may be configured to rotate independently of each other, such as e.g., by being arranged on separate drive shafts, or by being releasably connected to the same drive shaft by respective clutches.
In one or more exemplary spooling device(s), the auxiliary drum may be arranged on the first and/or the second flange of the main drum. The main drum and the auxiliary drum may share a flange, such that the second main flange is equal to the first auxiliary flange.
In other words, the main barrel may be connected to a first side of the shared flange and the auxiliary barrel may be connected to a second side of the shared flange, which second side is opposite the first side. The main drum and the auxiliary drum may thus be
The main drum may comprise a first and a second flange arranged on the longitudinal ends of the main drum, wherein the auxiliary drum is arranged on the first flange of the main drum. The first and second flanges of the main drum, which may also be referred to as a first and second main flange, may define side walls providing lateral support to the main line when the main line is stored on the main drum. The main drum may further comprise a barrel, which may be referred to as a main barrel for receiving the main line.
The main barrel may be coaxially arranged with the first and the second flange and may be located between the first and the second main flange. A diameter of the main barrel may be smaller than a diameter of the first and second main flanges.
In some exemplary spooling devices, the auxiliary drum may be comprised in the main drum, such that a section of the main drum, such as an end section close to a flange of the main drum (such as the second main flange) forms the auxiliary drum.
In some exemplary spooling devices, the auxiliary drum may also comprise a first and a second flange, which may be referred to as a first and a second auxiliary flange, and a barrel, which may be referred to as an auxiliary barrel. The auxiliary barrel may be arranged between the first and second auxiliary flange. A diameter of the auxiliary barrel may be smaller than a diameter of the first and second auxiliary flanges. The diameter of the auxiliary barrel may be different to the diameter of the main barrel. The main barrel and the auxiliary barrel may be configured to rotate independently of each other, such as e.g., by being arranged on separate drive shafts, or by being releasably connected to the same drive shaft by respective clutches.
In one or more exemplary spooling device(s), the auxiliary drum may be arranged on the first and/or the second flange of the main drum. The main drum and the auxiliary drum may share a flange, such that the second main flange is equal to the first auxiliary flange.
In other words, the main barrel may be connected to a first side of the shared flange and the auxiliary barrel may be connected to a second side of the shared flange, which second side is opposite the first side. The main drum and the auxiliary drum may thus be
7 configured to perform a simultaneous rotation. In one or more exemplary spooling devices, the auxiliary drum may be made from angle bar that is rolled to a suitable diameter.
The main drum may have a larger line capacity than the auxiliary drum. The main drum may e.g., have a smaller barrel diameter and a larger traverse (width of the barrel which is the same as the distance between the flanges of the drum) than the auxiliary drum.
In one or more exemplary spooling device(s), the spooling device may comprise a rotational drive system for rotating the drums around the longitudinal center axes of the drums. The rotational drive system may herein be referred to as a first drive system. The main drum and the auxiliary drum may be driven by respective first drive systems, such that the main drum and the auxiliary drum may be driven independently of each other. In one or more exemplary spooling device(s), the main drum and the auxiliary drum may be driven by one single first drive system. The first drive system may comprise one or more clutches being configured such that the main drum and the auxiliary drum may be driven independently of each other or to perform a joint rotation. In one or more exemplary spooling device(s), the main drum and the auxiliary drum may be rigidly connected such that one single rotational drive system drives both drums jointly.
When the main line is to be winded onto the spooling device, the guiding arm may be in the main position. The main drum, at least, may be rotated (the auxiliary drum may be stationary or rotating), such that the main line is winded onto the main drum.
Once the main line has been fully winded onto the main drum and the end of the auxiliary line connected to the main line passes the guiding arm (such as when the guiding arm is aligned with the end of the auxiliary line connected to the main line), the guiding arm may start the sweeping movement towards the auxiliary position. The guiding arm starting the sweeping movement may trigger the rotation of the main drum to be halted. When the guiding arm has reached the auxiliary position the rotation of the auxiliary drum (and the main drum) may be started or restarted. By stopping the rotation of the main drum while the guiding arm performs the sweeping movement, and restating the rotation once the guiding arm reaches the auxiliary position, it can be ensured that the winding of the auxiliary line is only commenced once the auxiliary line has been guided to the auxiliary drum. This prevents the auxiliary line from being winded onto the mooring rope on the main drum, which reduces the risk of the auxiliary line being caught in the mooring rope,
The main drum may have a larger line capacity than the auxiliary drum. The main drum may e.g., have a smaller barrel diameter and a larger traverse (width of the barrel which is the same as the distance between the flanges of the drum) than the auxiliary drum.
In one or more exemplary spooling device(s), the spooling device may comprise a rotational drive system for rotating the drums around the longitudinal center axes of the drums. The rotational drive system may herein be referred to as a first drive system. The main drum and the auxiliary drum may be driven by respective first drive systems, such that the main drum and the auxiliary drum may be driven independently of each other. In one or more exemplary spooling device(s), the main drum and the auxiliary drum may be driven by one single first drive system. The first drive system may comprise one or more clutches being configured such that the main drum and the auxiliary drum may be driven independently of each other or to perform a joint rotation. In one or more exemplary spooling device(s), the main drum and the auxiliary drum may be rigidly connected such that one single rotational drive system drives both drums jointly.
When the main line is to be winded onto the spooling device, the guiding arm may be in the main position. The main drum, at least, may be rotated (the auxiliary drum may be stationary or rotating), such that the main line is winded onto the main drum.
Once the main line has been fully winded onto the main drum and the end of the auxiliary line connected to the main line passes the guiding arm (such as when the guiding arm is aligned with the end of the auxiliary line connected to the main line), the guiding arm may start the sweeping movement towards the auxiliary position. The guiding arm starting the sweeping movement may trigger the rotation of the main drum to be halted. When the guiding arm has reached the auxiliary position the rotation of the auxiliary drum (and the main drum) may be started or restarted. By stopping the rotation of the main drum while the guiding arm performs the sweeping movement, and restating the rotation once the guiding arm reaches the auxiliary position, it can be ensured that the winding of the auxiliary line is only commenced once the auxiliary line has been guided to the auxiliary drum. This prevents the auxiliary line from being winded onto the mooring rope on the main drum, which reduces the risk of the auxiliary line being caught in the mooring rope,
8 which in turn reduces the risk of sudden pulls in the auxiliary line which could injure or kill personnel handling the spooling device. Thus, a safer spooling device and spooling operation is provided.
In some exemplary spooling device(s), the spooling device may comprise a detector for detecting/or determining that the end of the auxiliary line connected to the main line passes or is aligned with the guiding arm. The detector may e.g., be revolution counter on the main drum or a line length measurement machine, wherein the revolutions of the main drum and/or the line length measurement machine may be used to calculate the length of winded/un-winded mooring rope on the main drum. When the same amount of main line has been winded onto the main drum as has previously been un-winded from the main drum, the auxiliary line may be determined to be aligned with the guiding arm.
In one or more exemplary embodiments herein, the detector may be an optical or a magnetic sensor. The magnetic sensor may detect a magnet located at the end of the auxiliary line or a e.g., a steel material of the auxiliary line. The magnetic sensor may e.g., be a hall sensor. In one or more exemplary embodiments herein, the detector may be a wireless device, such as a Near Field Communication (NFC) device, such as e.g., a Radio-Frequency Identification (RFID) reader detecting an RFID-chip arranged at the end of the auxiliary line.
The guiding arm being arranged at a distance from the longitudinal center axis in the spooling direction, shall be understood as the guiding arm being arranged between the main drum and a free end of the auxiliary line, when the auxiliary line and/or the main line is in an un-winded state. This may also be referred to as the guiding arm being arranged in front of the main drum, a forward direction being the direction in which the main line leaves the main drum when the main line is un-winded. In other words, the guiding arm is arranged such that, when the main line and/or the auxiliary line is winded onto the main drum and/or the auxiliary drum from an un-winded state, the main line and/or the auxiliary line passes the location of the guiding arm. The guiding arm may be arranged at a distance larger than a radius of the largest flange of the main drum and/or the auxiliary drum, such that the guiding arm clears the flanges of the main drum and/or the auxiliary drum during the sweeping movement from the main position to the auxiliary position. The guiding arm may be arranged between the main drum and a fairlead or towing staple
In some exemplary spooling device(s), the spooling device may comprise a detector for detecting/or determining that the end of the auxiliary line connected to the main line passes or is aligned with the guiding arm. The detector may e.g., be revolution counter on the main drum or a line length measurement machine, wherein the revolutions of the main drum and/or the line length measurement machine may be used to calculate the length of winded/un-winded mooring rope on the main drum. When the same amount of main line has been winded onto the main drum as has previously been un-winded from the main drum, the auxiliary line may be determined to be aligned with the guiding arm.
In one or more exemplary embodiments herein, the detector may be an optical or a magnetic sensor. The magnetic sensor may detect a magnet located at the end of the auxiliary line or a e.g., a steel material of the auxiliary line. The magnetic sensor may e.g., be a hall sensor. In one or more exemplary embodiments herein, the detector may be a wireless device, such as a Near Field Communication (NFC) device, such as e.g., a Radio-Frequency Identification (RFID) reader detecting an RFID-chip arranged at the end of the auxiliary line.
The guiding arm being arranged at a distance from the longitudinal center axis in the spooling direction, shall be understood as the guiding arm being arranged between the main drum and a free end of the auxiliary line, when the auxiliary line and/or the main line is in an un-winded state. This may also be referred to as the guiding arm being arranged in front of the main drum, a forward direction being the direction in which the main line leaves the main drum when the main line is un-winded. In other words, the guiding arm is arranged such that, when the main line and/or the auxiliary line is winded onto the main drum and/or the auxiliary drum from an un-winded state, the main line and/or the auxiliary line passes the location of the guiding arm. The guiding arm may be arranged at a distance larger than a radius of the largest flange of the main drum and/or the auxiliary drum, such that the guiding arm clears the flanges of the main drum and/or the auxiliary drum during the sweeping movement from the main position to the auxiliary position. The guiding arm may be arranged between the main drum and a fairlead or towing staple
9 guiding the line in an un-winded state, such as between the main drum and the first fairlead or towing staple for guiding the line, seen from the main drum.
The guiding arm may be configured to be positioned in a main position in which the guiding arm allows the main line to be spooled onto the main drum and to be positioned in an auxiliary position in which the guiding arm guides the auxiliary line onto the auxiliary drum. The main position may e.g., be a position in which the guiding arm does not guide a line, such as the auxiliary line and/or the main line. When the guiding arm performs the sweeping movement from the main position to the auxiliary position, the guiding arm may be configured to intersect the auxiliary line and to force, such as pull or push, the auxiliary line towards the auxiliary drum. The guiding arm may be configured to perform the sweeping movement between the main position and the auxiliary position when an end of the auxiliary line connected to the main line passes the position of the guiding arm during a spooling procedure. In other words, when the guiding arm is in the main position the guiding arm may not be in contact with the line, such as the auxiliary line and/or the main line. During the movement from the main position to the auxiliary position the guiding arm may intersect the auxiliary line, such that the guiding arm contacts the auxiliary line and forces the auxiliary line onto the auxiliary drum. The guiding arm may thus only be in contact with the line when the auxiliary line is to be guided onto the auxiliary drum. By the guiding arm not being in constant contact with the line during spooling the wear on the line, caused e.g., by friction between the guiding arm and the line, can be reduced.
The guiding arm may further comprise a guiding element for contacting the auxiliary line.
In other words, the guiding element is configured to contact the auxiliary line, such as when the guiding arm is in the auxiliary position. In one or more exemplary spooling device(s), the guiding element may comprise a line contacting surface for contacting the auxiliary line, wherein the line contacting surface may be configured to reduce friction on the auxiliary line. The guiding element may e.g., be coated with a material having a lower friction coefficient than the uncoated surface.
In one or more exemplary spooling device(s), the guiding element may be a guide roller rotatably arranged in relation to a main element of the guiding arm. The guide roller may be configured to rotate around a longitudinal axis of the guiding arm. A
surface of the guide roller may be configured to increase friction between the auxiliary line and the guide roller, such that a moment acting on the guide roller from the auxiliary line overcomes a breakaway moment of the guide roller. This ensures that the guide roller is rolling and not sliding along the auxiliary line. If the auxiliary line would be sliding along the guide rollers, the wear of the auxiliary line may increase, which is undesired. The guide rollers may e.g., be coated with a material having a higher friction coefficient than the uncoated guide 5 rollers.
When the guiding arm is in the auxiliary position the guiding arm, or the guiding element of the guiding arm, may be aligned with an inner surface of the first flange of the auxiliary drum, such that the auxiliary line being guided by the guiding arm or the guiding element is winded onto the auxiliary drum.
The guiding arm may be configured to be positioned in a main position in which the guiding arm allows the main line to be spooled onto the main drum and to be positioned in an auxiliary position in which the guiding arm guides the auxiliary line onto the auxiliary drum. The main position may e.g., be a position in which the guiding arm does not guide a line, such as the auxiliary line and/or the main line. When the guiding arm performs the sweeping movement from the main position to the auxiliary position, the guiding arm may be configured to intersect the auxiliary line and to force, such as pull or push, the auxiliary line towards the auxiliary drum. The guiding arm may be configured to perform the sweeping movement between the main position and the auxiliary position when an end of the auxiliary line connected to the main line passes the position of the guiding arm during a spooling procedure. In other words, when the guiding arm is in the main position the guiding arm may not be in contact with the line, such as the auxiliary line and/or the main line. During the movement from the main position to the auxiliary position the guiding arm may intersect the auxiliary line, such that the guiding arm contacts the auxiliary line and forces the auxiliary line onto the auxiliary drum. The guiding arm may thus only be in contact with the line when the auxiliary line is to be guided onto the auxiliary drum. By the guiding arm not being in constant contact with the line during spooling the wear on the line, caused e.g., by friction between the guiding arm and the line, can be reduced.
The guiding arm may further comprise a guiding element for contacting the auxiliary line.
In other words, the guiding element is configured to contact the auxiliary line, such as when the guiding arm is in the auxiliary position. In one or more exemplary spooling device(s), the guiding element may comprise a line contacting surface for contacting the auxiliary line, wherein the line contacting surface may be configured to reduce friction on the auxiliary line. The guiding element may e.g., be coated with a material having a lower friction coefficient than the uncoated surface.
In one or more exemplary spooling device(s), the guiding element may be a guide roller rotatably arranged in relation to a main element of the guiding arm. The guide roller may be configured to rotate around a longitudinal axis of the guiding arm. A
surface of the guide roller may be configured to increase friction between the auxiliary line and the guide roller, such that a moment acting on the guide roller from the auxiliary line overcomes a breakaway moment of the guide roller. This ensures that the guide roller is rolling and not sliding along the auxiliary line. If the auxiliary line would be sliding along the guide rollers, the wear of the auxiliary line may increase, which is undesired. The guide rollers may e.g., be coated with a material having a higher friction coefficient than the uncoated guide 5 rollers.
When the guiding arm is in the auxiliary position the guiding arm, or the guiding element of the guiding arm, may be aligned with an inner surface of the first flange of the auxiliary drum, such that the auxiliary line being guided by the guiding arm or the guiding element is winded onto the auxiliary drum.
10 In one or more exemplary spooling devices, the guiding arm may be pivotably arranged in relation to the main drum, such that the guiding arm is configured to pivot between the main position and the auxiliary position. The spooling device may comprise a pivot point around which the guiding arm is configured to pivot. The pivot point may be configured such that a longitudinal axis of the guiding arm, in the main position, is arranged in parallel (at least substantially) with the longitudinal center axis of the main drum, which may also be referred to as being in a horizontal position. The pivot point may further be configured such that, when the guiding arm is in the auxiliary position, the longitudinal axis of the guiding arm is arranged perpendicularly (at least substantially) with the longitudinal center axis of the main drum, which may also be referred to as being in a vertical position. The sweeping movement of the guiding arm may thus, in one or more exemplary spooling device(s) cover a span of 90 , at least substantially, from the main position to the auxiliary position. The span of the sweeping movement of the guiding arm 30 may be in a plane parallel to the longitudinal center axis 15.
In one or more exemplary spooling device(s), the guiding arm may be slidably arranged in relation to the main drum, such that the guiding arm is configured to perform a translational movement from the main position to the auxiliary position. The guiding arm may e.g., be arranged in a longitudinal guideway, such as a groove or a rail, in which guideway the guiding arm can be slid between the main position and the auxiliary position. The guiding arm may e.g., perform the translational movement parallel with the longitudinal center axis of the main drum. In the main position, the guiding arm, or the guiding element of the guiding arm, may be positioned perpendicularly to the longitudinal center axis of the main drum in the vicinity of the first main flange. The guiding arm, or the
In one or more exemplary spooling device(s), the guiding arm may be slidably arranged in relation to the main drum, such that the guiding arm is configured to perform a translational movement from the main position to the auxiliary position. The guiding arm may e.g., be arranged in a longitudinal guideway, such as a groove or a rail, in which guideway the guiding arm can be slid between the main position and the auxiliary position. The guiding arm may e.g., perform the translational movement parallel with the longitudinal center axis of the main drum. In the main position, the guiding arm, or the guiding element of the guiding arm, may be positioned perpendicularly to the longitudinal center axis of the main drum in the vicinity of the first main flange. The guiding arm, or the
11 guiding element of the guiding arm, may e.g., be aligned with an outer surface of the first main flange, in the main position. The guiding arm may perform the sweeping translational movement to the auxiliary position, e.g., along the guideway, in which the guiding arm or the guide element of the guiding arm may be aligned with the inner surface of the first auxiliary flange. During the translational movement, the guiding arm is configured to intersect the auxiliary line and to force, such as pull or push, the auxiliary line towards the auxiliary drum.
The spooling device may comprise a drive system for moving the guiding arm, such as between the main position and the auxiliary position. The drive system may e.g., be a hydraulic drive system, an electrical drive system, a pneumatic drive system or a combination thereof. The drive system for moving the guiding arm may herein also be referred to as a second drive system. The hydraulic drive system and/or the pneumatic drive system may comprise a cylinder, such as a hydraulic or pneumatic cylinder, creating a linear displacement which may be translated into a rotational or translational movement of the guiding arm.
The spooling device may further comprise a line tensioning device configured to create a tension on the auxiliary line when the auxiliary line, such as when the auxiliary line has been guided onto the auxiliary drum. The line tensioning device may be configured to abut the auxiliary line when the guiding arm is in the auxiliary position. The line tensioning device may be configured to abut the auxiliary line from an opposite side as the guiding arm, such that the auxiliary line may be squeezed between the line tensioning device and the guiding arm. By creating a tension force on the auxiliary line, a holding force may be created which counteracts a weight of an eyelet of the main line, such that if the eyelet of the main line slides of the drum it does not pull the auxiliary line with it.
The line tensioning device may thus reduce any sudden pulls that may cause a person handling the auxiliary line to fall over, drag the person over the ship or over an edge of a quay or may smash the person against the vessel or equipment mounted or stored on the vessel, and thus provides a safer spooling device. In one or more exemplary spooling device(s), the line tensioning device may comprise a guiding surface configured to be in contact with the auxiliary line. The guiding surface may comprise protrusions or may be coated with a friction increasing material, such as e.g., a rubber material, for increasing a friction between the line tensioning device and the auxiliary line.
The spooling device may comprise a drive system for moving the guiding arm, such as between the main position and the auxiliary position. The drive system may e.g., be a hydraulic drive system, an electrical drive system, a pneumatic drive system or a combination thereof. The drive system for moving the guiding arm may herein also be referred to as a second drive system. The hydraulic drive system and/or the pneumatic drive system may comprise a cylinder, such as a hydraulic or pneumatic cylinder, creating a linear displacement which may be translated into a rotational or translational movement of the guiding arm.

In one or more exemplary spooling device(s), the line tensioning device may comprise a guiding surface configured to be in contact with the auxiliary line. The guiding surface may comprise protrusions or may be coated with a friction increasing material, such as e.g., a rubber material, for increasing a friction between the line tensioning device and the auxiliary line.
12 In one or more exemplary spooling device(s), the line tensioning device comprises a tensioning roller configured to abut the auxiliary line and to rotate around an axis extending perpendicularly to the spooling direction of the auxiliary line. The tensioning roller may comprise a drive system, such as a third drive for rotating the tensioning roller.
In order to tension the auxiliary line during the spooling procedure (such as when winding the auxiliary line onto the auxiliary drum), a rotational force may be applied to the tensioning roller, by means of the drive system, which rotational force acts in the opposite direction to the force applied to the tensioning roller by the auxiliary line.
The rotational force applied by the drive system may be smaller than the rotational force applied to the tensioning roller by the auxiliary line, such that the tensioning roller follows the rotation of the auxiliary line but creates a resistance which tensions the auxiliary line.
In other words, the rotational force applied by the drive system is not high enough to overcome the rotational force applied to the tensioning roller by the auxiliary line. When no force is applied by the spooling device, such as when the drums, such as the main drum and/or the auxiliary drum, are freespooling, the rotational force applied to the tensioning roller by the drive system may be high enough to unwind the auxiliary line from the auxiliary drum.
In one or more exemplary spooling devices and/or spooling systems, the tensioning roller may thus be used for unwinding the auxiliary line from the auxiliary drum.
Thus, the unwinding of the auxiliary line may be autonomously handled.
In one or more exemplary spooling devices, the auxiliary drum may form part of the main drum, such as be a section of the main drum. The auxiliary drum may e.g., be a section, such as an end section of the main drum. In these one or more exemplary spooling devices the auxiliary line may be spooled on top of or beside the main line.
The guiding arm may be used to move the auxiliary line to the section of the main drum constituting the auxiliary drum. The auxiliary drum may be open to one side, such as only comprising one flange, such as only one auxiliary flange. In this case, the second main flange and the second auxiliary flange may be the same. The auxiliary line may be guided by the auxiliary flange, such as the second auxiliary flange, and the guiding arm.
The guiding arm may thus be configured act as a flange, such as a first flange, of the auxiliary drum, when the guiding arm is in the auxiliary position. The width of the auxiliary drum may thus be defined by the distance between the guide surface of the guiding arm and the second auxiliary flange, such as the second main flange.
In order to tension the auxiliary line during the spooling procedure (such as when winding the auxiliary line onto the auxiliary drum), a rotational force may be applied to the tensioning roller, by means of the drive system, which rotational force acts in the opposite direction to the force applied to the tensioning roller by the auxiliary line.
The rotational force applied by the drive system may be smaller than the rotational force applied to the tensioning roller by the auxiliary line, such that the tensioning roller follows the rotation of the auxiliary line but creates a resistance which tensions the auxiliary line.
In other words, the rotational force applied by the drive system is not high enough to overcome the rotational force applied to the tensioning roller by the auxiliary line. When no force is applied by the spooling device, such as when the drums, such as the main drum and/or the auxiliary drum, are freespooling, the rotational force applied to the tensioning roller by the drive system may be high enough to unwind the auxiliary line from the auxiliary drum.

The auxiliary drum may be open to one side, such as only comprising one flange, such as only one auxiliary flange. In this case, the second main flange and the second auxiliary flange may be the same. The auxiliary line may be guided by the auxiliary flange, such as the second auxiliary flange, and the guiding arm.
The guiding arm may thus be configured act as a flange, such as a first flange, of the auxiliary drum, when the guiding arm is in the auxiliary position. The width of the auxiliary drum may thus be defined by the distance between the guide surface of the guiding arm and the second auxiliary flange, such as the second main flange.
13 In one or more exemplary spooling devices, the auxiliary drum is separate from the main drum. The auxiliary drum may e.g., be separated from the main drum by means of a flange, such that the main line and the auxiliary line are separate from each other when the main line and the auxiliary line are winded onto the main and auxiliary drums.
A spooling system is disclosed, comprising the spooling device, a main line (such as a mooring line, a towing line or a hawser) and an auxiliary line (such as a messenger line or a heaving line), wherein the auxiliary line is connected to a distal end of the main line, such as to an eyelet of the main line.
Further, a vessel comprising the spooling system, such as e.g., one or more spooling system(s), is disclosed. The vessel may e.g., be a ship or a mooring support vessel, such as a tugboat.
Fig. 1 illustrates a front view of a known spooling device 1 for winding and/or unwinding a main line 13 and an auxiliary line 14. In the know solution the main line 13 and the auxiliary line 14 are spooled on the same drum 10. The auxiliary line 14 is connected to a distal end of the main line, such that when the main line 13 and the auxiliary line 14 are winded onto the drum 10 by rotation of the drum in a first direction around the center axis 15, the main line 13 is winded onto the drum first and once the main line has been completely winded onto the drum the auxiliary line 14 is winded onto the drum 10 on top of the main line 13. Similarly, when the lines 13 and 14 are un-winded, the drum is rotated in a second direction opposite the first direction around the center axis 15, such that the auxiliary line 14 is un-winded first and once the auxiliary line 14 has been completely un-winded the main line 13 starts to unwind from the drum 10. However, since the auxiliary line 14 is much thinner than the main line 13, the auxiliary line 14 may slide between and get stuck in between two wraps, such as between two coils, of the winded main line 13. A
stuck auxiliary line is indicated in Fig. 1 as 14A. This may e.g., be the case if the auxiliary line 14 is pulled hard, such as if an eyelet of the main line, to which the auxiliary line 14 may be connected and which may be very heavy, slides of the drum 10 and pulls the auxiliary line 14 with it. As a consequence, the auxiliary line 14 may, during an unwinding procedure, not unwind properly. Instead, the auxiliary line 14 may follow the rotation of the drum 10 in the second direction and may start to wind onto the drum again in the second direction. This presents a danger to personnel handling the spooling device and the auxiliary line. If the auxiliary line 14 suddenly starts to wind onto the drum during an

This presents a danger to personnel handling the spooling device and the auxiliary line. If the auxiliary line 14 suddenly starts to wind onto the drum during an
14 unwinding procedure, the auxiliary line 14 will instead of being released from the drum 10 be pulled back onto the drum 10. Such a pull of the auxiliary line 14 may cause a person handling the auxiliary line to fall over, drag the person over the ship or over an edge of a quay or may smash the person against the vessel or equipment mounted or stored on the vessel, which may in turn lead to severe injuries or even death.
Fig. 2 shows a front view of an exemplary spooling device 1 for line handling on a vessel according to this disclosure. The front view shall herein (such as throughout this disclosure) be understood as seen from a free end of an un-winded line, such as an auxiliary line or a main line, towards the spooling device 1.

The main drum 10 is configured to wind and/or unwind the main line in a spooling direction. The spooling direction is perpendicular (at least substantially perpendicular) to the longitudinal centre axis of the main drum 10. The spooling device 1 further comprises an auxiliary drum 20 for spooling of an auxiliary line (not shown in Fig. 2), such as a messenger line or a heaving line, connected to a distal end of the main line. In the exemplary spooling device shown in Fig. 2, the auxiliary drum 20 is arranged side-by-side and coaxially with the main drum 10 along the longitudinal center axis 15, such that the main drum 10 and the auxiliary drum 20 share the same rotation axis. The spooling device 1 further comprises a guiding arm 30 movably arranged in relation to the main drum 10 and the auxiliary drum 20 at a distance from the longitudinal center axis 15 in the spooling direction. The guiding arm 30 is configured to perform a sweeping movement in relation to the main drum 10, such that the guiding arm 30 is configured to guide the auxiliary line onto the auxiliary drum 20 during a spooling procedure.
The main drum 10 may comprise a first flange 11A and a second flange 11B, which may also be referred to as main flanges 11A and 11B, arranged on longitudinal ends of the main drum 10. In the exemplary spooling device shown in Fig. 2, the auxiliary drum 20 is arranged on the second flange 11B of the main drum 10. The main drum 10 further comprises a barrel 12, which may be referred to as a main barrel for receiving the main line. The main barrel 12 may be coaxially arranged with the first and the second flange and may be located between the first and the second main flange 12A, 12B. A
diameter of the main barrel may be smaller than a diameter of the first and second main flanges.
The auxiliary drum 20 also comprises a first and a second flange 21A, 21B, which may be referred to as a first and a second auxiliary flange, and a barrel 22, which may be referred to as an auxiliary barrel. The auxiliary barrel 22 may be arranged between the first and second auxiliary flange 21A, 21B. A diameter of the auxiliary barrel 22 is smaller than a 5 diameter of the first and second auxiliary flanges 21A, 21B. The diameter of the auxiliary barrel may be different to the diameter of the main barrel. In the exemplary spooling device shown in Fig, 2, the auxiliary drum 20 is arranged on the second flange 11B of the main drum 10. The main drum 10 and the auxiliary drum 20 thus share a flange, such that the second main flange 11B is equal to the first auxiliary flange 21A. In other words, the 10 main barrel may be connected to a first side of the shared flange 11B, 21A and the auxiliary barrel may be connected to a second side of the shared flange, which second side is opposite the first side. The main drum 10 and the auxiliary drum 20 may thus be configured to perform a simultaneous rotation. The guiding arm 30 is configured to be positioned in a main position Pm in which the guiding arm 30 allows, or is configured to
Fig. 2 shows a front view of an exemplary spooling device 1 for line handling on a vessel according to this disclosure. The front view shall herein (such as throughout this disclosure) be understood as seen from a free end of an un-winded line, such as an auxiliary line or a main line, towards the spooling device 1. The spooling device 1 comprises a main drum 10 for spooling of the main line (not shown in Fig. 2), wherein the main drum 10 is configured to rotate around the longitudinal center axis 15.
The main drum 10 is configured to wind and/or unwind the main line in a spooling direction. The spooling direction is perpendicular (at least substantially perpendicular) to the longitudinal centre axis of the main drum 10. The spooling device 1 further comprises an auxiliary drum 20 for spooling of an auxiliary line (not shown in Fig. 2), such as a messenger line or a heaving line, connected to a distal end of the main line. In the exemplary spooling device shown in Fig. 2, the auxiliary drum 20 is arranged side-by-side and coaxially with the main drum 10 along the longitudinal center axis 15, such that the main drum 10 and the auxiliary drum 20 share the same rotation axis. The spooling device 1 further comprises a guiding arm 30 movably arranged in relation to the main drum 10 and the auxiliary drum 20 at a distance from the longitudinal center axis 15 in the spooling direction. The guiding arm 30 is configured to perform a sweeping movement in relation to the main drum 10, such that the guiding arm 30 is configured to guide the auxiliary line onto the auxiliary drum 20 during a spooling procedure.
The main drum 10 may comprise a first flange 11A and a second flange 11B, which may also be referred to as main flanges 11A and 11B, arranged on longitudinal ends of the main drum 10. In the exemplary spooling device shown in Fig. 2, the auxiliary drum 20 is arranged on the second flange 11B of the main drum 10. The main drum 10 further comprises a barrel 12, which may be referred to as a main barrel for receiving the main line. The main barrel 12 may be coaxially arranged with the first and the second flange and may be located between the first and the second main flange 12A, 12B. A
diameter of the main barrel may be smaller than a diameter of the first and second main flanges.
The auxiliary drum 20 also comprises a first and a second flange 21A, 21B, which may be referred to as a first and a second auxiliary flange, and a barrel 22, which may be referred to as an auxiliary barrel. The auxiliary barrel 22 may be arranged between the first and second auxiliary flange 21A, 21B. A diameter of the auxiliary barrel 22 is smaller than a 5 diameter of the first and second auxiliary flanges 21A, 21B. The diameter of the auxiliary barrel may be different to the diameter of the main barrel. In the exemplary spooling device shown in Fig, 2, the auxiliary drum 20 is arranged on the second flange 11B of the main drum 10.

During its sweeping movement towards the auxiliary position PA the guiding arm 30 has intersected the auxiliary line 14 and has guided the auxiliary line 14 onto the auxiliary drum 20. The spooling direction of the spooling device 1 is to the right in the Fig. 5, as indicated by the un-winded auxiliary line 14. As can be seen in Fig. 5, the guiding arm 30 is arranged at a distance DArm from the longitudinal center axis 15 in the spooling direction SD of the spooling device 1. The distance DArm is larger than a radius rIVIAX of the largest flange 11A, 11B of the main drum and/or the largest flange 21A, 21B of the auxiliary drum 20, such that the guiding arm 30 clears the flanges of the main drum 10 and/or the auxiliary drum 20 during the sweeping movement from the main position Pm to the auxiliary position PA.

During its sweeping movement towards the auxiliary position PA the guiding arm 30 has intersected the auxiliary line 14 and has guided the auxiliary line 14 onto the auxiliary drum 20. The spooling direction of the spooling device 1 is to the right in the Fig. 5, as indicated by the un-winded auxiliary line 14. As can be seen in Fig. 5, the guiding arm 30 is arranged at a distance DArm from the longitudinal center axis 15 in the spooling direction SD of the spooling device 1. The distance DArm is larger than a radius rIVIAX of the largest flange 11A, 11B of the main drum and/or the largest flange 21A, 21B of the auxiliary drum 20, such that the guiding arm 30 clears the flanges of the main drum 10 and/or the auxiliary drum 20 during the sweeping movement from the main position Pm to the auxiliary position PA.
