Definitions

  • the present disclosure pertains to the field of mooring of vessels.
  • the present disclosure relates to a line handling device grabbing and handling a line, such as a mooring line, during a mooring operation, and a vessel comprising the line handling device.
  • 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.
  • 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 four to six mooring lines.
  • 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. 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.
  • GB 2568535 A discloses a line handling system for a tugboat.
  • the line handling system comprises an actuatable coupling mechanism for coupling together a line of the tugboat and a line of a marine vessel by applying a connector to the lines when actuated.
  • the connector comprises a length of wire cut from a supply and wrapped about the lines and twisted together to connect the lines.
  • the line handling system may be equipped with a pair of prongs which act as a line engager to engage the line of the marine vessel.
  • a line handling device for a vessel comprises a main body comprising a first main body section and a second main body section.

  • the second set of catching arms is configured to position the second line such that the second line comes in contact with the eye of the first line in the first position.

  • the method comprises catching, using the first set of catching arms, a first line from the second vessel:
  • the method comprises receiving an eye of the first line in the receptacle.
  • the method comprises catching, using the second set of catching arms, the second line.
  • the risk of personnel getting injured is reduced, since the line can be handled without personnel directly handling the line.
  • the personnel may be located at a safe distance from the line during the mooring procedure, thereby reducing the risk of injuries for example in case of a snap-back of a mooring line.
  • a safe mooring operation can be provided.
