Definitions
- the present disclosure pertains to the field of mooring of vessels.
- the present disclosure relates to a mooring device for securing a vessel to a mooring point, a mooring system for securing a vessel to a mooring point, and a vessel comprising the mooring system.
- 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. 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. 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 so called mooring winches or capstans.
- 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.
- mooring of a vessel involves hard labor with risk for injuries for the people on shore.
- mooring operations are time consuming and must be planned in advance to ensure that people are available onshore to assist during mooring.
- a mooring device for securing a vessel to a mooring point comprises a main body having a guide section and a receiving section for receiving the mooring point.
- the guide section is arranged along a perimeter of the receiving section, the guide section being arc shaped and having a center axis.
- the mooring device further comprises a guiding arc being arranged in the guide section of the main body, wherein the guiding arc is arranged concentrically with and rotatably around the center axis of the guide section.
- the mooring device further comprises a catching device arranged at the circumference of the guiding arc for catching and holding a line, the guiding arc comprising an open section allowing the mooring point to enter the receiving section.
- the guiding arc is configured to rotate in a first direction around the receiving section of the main body such that, when the mooring point is located in the receiving section, the catching device forms a trajectory encircling the mooring point, such that, when the line is caught and held by the catching device, the line encircles the mooring point located in the receiving section.
- One or more edges of the receiving section may be smoothened, such as being rounded, to reduce wear on a line sliding along the edge of the receiving section.
- a mooring system for securing a vessel to a mooring point.
- the mooring system comprising the mooring device and a line.
- the catching device catches the line and pulls a section of the line that is caught in the catching device along a trajectory encircling the receiving section, such that the line encircles a mooring point located in the receiving section.
- a vessel comprising the mooring system. It is an advantage of the present disclosure that the time and effort for performing a mooring procedure may be reduced, since the mooring device can grab the line and place the line around a mooring point in one single rotational movement, without requiring manual handling of the line.
- the mooring device of the present disclosure thus enables remotely operated vessels to moor to offshore mooring points, such as pylons, or in remote locations without assistance from shore personnel.
- the personnel may be located at a safe distance from the line in turn providing a safe mooring operation.

- the guide section being arc shaped and having a center axis.
- the mooring device further comprises the guiding arc being arranged in the guide section of the main body.
- the guiding arc is arranged concentrically with and rotatably around the center axis of the guide section.
- the mooring device further comprises a catching device arranged at the circumference of the guiding arc for catching and holding a line, such as a mooring line.
- the guiding arc comprises an open section allowing the mooring point to enter the receiving section.
- the guiding arc is configured to rotate in a first direction around the receiving section of the main body, such that, when the mooring point is located in the receiving section, the catching device forms a trajectory encircling the mooring point, such that, when the line is caught and held by the catching device, the line encircles (at least partly) the mooring point located in the receiving section.
- the receiving section may be an open section in the main body, such as a through-going cut out in the main body.
- the receiving section may be defined by one or more side walls of the main body.
- An opening may be provided in the side of the main body for allowing an object, such as a mooring point, to be inserted into the receiving section.
- the opening in the side of the main body may be an opening providing access to the receiving section in a direction perpendicular to the center axis of the guide section.
- the receiving section is arranged within the perimeter of the guide section and the guiding arc, such that the guide section and guiding arc surrounds the receiving section.
- the periphery of the receiving section may have one of the following shapes, U-shaped, arc shaped, V-shaped, or trapez-shaped.
- the dimensions of the receiving section are selected such that the receiving section and the opening in the side wall can accommodate a mooring point.
- a diameter or a width of the receiving section may be in the range of 0,5-3 meters, such as in the range of 1-2 meters, such as in the range of 1 ,2-1 ,5 meters.
- the receiving section may be a through hole arranged in the main body, such as in a main plane of the main body and being surrounded by the guide section.
- the guide section may be a groove, such as a milled groove, or a rail, mounted on the surface of the main body, surrounding the through hole.

- the main body, the guiding arc and/or the catching device of the mooring device may be made out of metal, such as stainless steel or aluminum.
- the mooring point may be any variety of shore fixtures, from trees and rocks to specially constructed fixed structures or areas such as quays, wharfs, jetties, piers, anchor buoys, mooring buoys, and/or wire or rope loops connected to any of the previous structures.
- the catching device may catch the line at a first end of the line.
- a surface of the catching device being configured to be in contact with the line may comprise a plurality of protrusions or a coating, such as a rubber material, for increasing friction between the surface and the line.
- the mooring line may comprise a sleeve arranged at the first end of the line, the sleeve may comprise a friction enhancing material or coating, such as a rubber material, for increasing friction between the catching device and the line. This may reduce the risk of the line unintentionally releasing from the catching device.
- the mooring device may further comprise a locking device for preventing the guiding arc from rotating in a second direction opposite the first direction.
- the locking device may be a ratchet, such as a ratchet element, arranged on the main body and being configured to engage the guiding arc, such that the ratchet allows a rotation of the guiding arc in one direction and prevents a rotation in the opposite direction.
- the locking device may be a pin arranged on the main body and being configured to engage the guiding arc when the guiding arc is in a fixed position, thereby preventing the guiding arc from rotating.
- the end section of the line caught by the catching device will be restricted in movement, instead the other end of the line may be un-winded from the other end.
- the first end of the line may be secured by the catching device and the guiding arc may be prevented from rotating by the locking device, such that when the mooring device moves away from the mooring point the line is un-winded from a storage to which a second end of the line is attached, such as from a winch, such as from a tension winch, such as from a drum of the winch.
- the size of the loop of the line can thereby be increased to allow the mooring device (and a vessel comprising the mooring device) to move away from the mooring point while the line still encircles (at least partly) the mooring point.
- the tension in the line may be adjusted by means of for example the winch, such as the tension winch, to provide less or more slack in the line.
- the mooring device may comprise a releasing device for releasing the line from the catching device.
- the releasing device allows the line to be removed from the mooring point by pulling a second end of the line to unloop the line from the mooring point.
- the releasing device may be configured to decrease the force by which the catching device holds the line, for example by increasing a gap between two surfaces between which the line is clamped, wedged or gripped.
- people on shore would have to manually remove the line from the mooring point, or the vessel would have to be brought close to the mooring point, such that people onboard of the vessel could remove the line from the mooring point which is time consuming.
- the mooring device of the present disclosure further reduces the time and effort for releasing the vessel from the mooring point.
- the releasing device may be an actuating member, such as an actuator, pushing the line out of the catching device.
- the catching device may comprise one or more jaws being configured to grasp the line in a closed position of the jaws.
- the jaws may be pivotably arranged to each other around a pivot point, such that the jaws can pivot between a closed and an open position. In the closed position the catching device is configured to catch and hold the line and in the open position the catching device may be configured to release the line.
- the catching device may further comprise a spring, which spring presses the jaws together in the closed position.
- the releasing device may comprise an actuating member configured to move at least one of the one or more jaws into an open position in which the jaws are configured to release the line.
- the releasing device may be located at a perimeter of the guiding section, such that the releasing device contacts the catching device when the catching device passes the location of the releasing device during rotation and forces the one or more jaws into the open position.
- the actuating member may contact one or more of the jaws of the catching device and may exert a force on the one or more jaws.
- the force exerted on the one or more jaws by the actuating member overcomes the spring force from the spring, which allows the one or more jaws to pivot from the closed position into the open position which releases the line.
- the actuating member may be fixedly arranged to the main body at a perimeter of the guiding section.
- the releasing device may further comprise a following member arranged on one of the one or more jaws and protruding outwards in a radial direction of the guiding arc, such that the following member is configured to contact and follow the actuating member mounted at the perimeter of the guiding section.
- the mooring device may further comprise a cover plate arranged over the guide section at the working position, which cover plate is configured to contact, such as abut, at least one of the one or more jaws of the catching device, to ensure that the jaws cannot open when the line is held by the one or more jaws of the catching device.
- the catching device In the working position the catching device may be positioned under the cover plate, such that the cover plate contacts the one or more jaws and forces them into the closed position.
- the guiding arc may be configured to be arranged in a working position, which may also be referred to as an initial position or an open position, in which the open section is arranged to allow the mooring point to be inserted into and/or removed from the receiving section of the main body.
- a working position which may also be referred to as an initial position or an open position, in which the open section is arranged to allow the mooring point to be inserted into and/or removed from the receiving section of the main body.
- the openings in the guiding arc, the guide section and the receiving section are aligned such that the mooring point can be inserted into the receiving section.
- the guiding arc In the initial position the guiding arc may be fully arranged within the main body, such as within the guide section of the main body. In addition to allowing an object to be inserted into the receiving section through the aligned openings and, this position also protects the guiding arc during a mooring procedure.
- the guiding arc would be in a protruding position, such as when the leading free end or the trailing free end has left the guide section, the guiding arc might be damaged or deformed if it would come in contact with the mooring point or any other fixed structure during the mooring procedure, such as when the mooring device is brought in vicinity of the mooring point to position the mooring point in the receiving section. Damage or deformation of the guiding arc may lead to malfunction of the mooring device since the guiding arc may no longer align with the guide section and thus prevent rotation of the guiding arc. Thus, positioning the guiding arc in the initial position protects the guiding arc from being damaged or deformed during a mooring procedure.
- the main body may further comprise a line guiding device, such as a fairlead, for releasably holding the line in a position where the catching device can catch the line during rotation of the guiding arc, which position may also be referred to as a catching position.

- the line is arranged such that it intersects a path of travel of the catching device during rotation of the guiding arc, thereby allowing the catching device to catch the line during rotation of the guiding arc.
- the line guiding device may further comprise one or more guiding rollers being rotatable arranged to the main body, such that, when the line is abutting the rollers and is being pulled, the rollers roll along the line, thereby reducing friction between the line and the line guiding device. This reduces the wear on the line and consequently reduces a risk of failure of the line, thereby increasing safety during the mooring operation.
- the guiding arc may be configured to be arranged in the catching position in which the catching device is arranged to catch the line. In the catching position the catching device is positioned to grab the line held by the guiding device.
