  • the towline is connected to a bollard on the assisted vessel.
  • the tasks performed by special purpose crafts may range from ice breaking to waterway maintenance, including various situations that might necessitate the attach ment of a vessel to another through a rope.
  • a similar system can also be used for mooring a vessel at a berth .
  • the usual manner to connect a vessel to a special purpose craft or to a berth is to throw a heaving line from the vessel being attached on the deck of the special purpose craft or on the berth, re spectively.
  • a crew member on the special purpose craft then picks the heaving line and ties it to an end of the towline.
  • the heaving line and the connected tow- line are then heaved to the vessel, released from each other, and the towline is secured to a bollard or oth er structures of the vessel.
  • the heaving line may already be connected to a mooring line of the ves- sel, and a member of the mooring crew, also called a linesman, picks the heaving line and heaves the moor ing line, along with the heaving line, to berth. Then, the heaving line is released form the mooring line, and the mooring line is secured to a bollard or other structures of the berth.
  • the manual arrangement has drawbacks, for ex ample that a crew member is needed to be present on the deck of the special purpose craft. In harsh weath er, the working conditions can be uncomfortable, or even hazardous. Additionally, the heaving line has a weight attached to its end to facilitate throwing, and being hit by the weight can injure a person on deck or on berth.

  • the rope-handling system may remove or reduce the need of a crew member on the deck of the special purpose craft when a vessel is being connected by an attachment rope.
  • the rope-handling system is designed to catch the heaving line thrown from the vessel by the Y fork of the guiding pole.
  • the Y fork is thus po sitioned so that it can catch the heaving line.
  • a heaving line is a line or a suitable rope thrown from a vessel to another vessel or to land in order to move a rope (such as a towline or a mooring line) between the vessels or between land and a vessel.
  • the rope is attached to the heaving line, and the heaving line is heaved to the direction in which the rope is meant to be moved. Oftentimes, and attachment rope is retrieved with the help of a heaving line.
  • the structure and po- sitioning of the line-engaging means may further allow connecting the attachment rope with the heaving line without further devices or manual steps.
  • the mooring line may first be attached to the heaving line. This attachment is done suitably far away from the end with the monkey-fist, so that the monkey-fist can be flung to the Y fork on land.

  • attachment rope is used for a tow- line, or other line used to connect a special purpose craft, for example a tug, with an assisted vessel, and for a mooring line used for connecting a vessel to land structures.
  • the guiding pole being convertible between storage configuration and an operating configuration is meant that the guiding pole can be repeatedly transferred between the storage configuration and the operating configuration.
  • the current rope-handling system may be used by first extending or pivoting the guiding pole to a sufficient height and opening the arms of the Y fork.
  • the line-engaging means is positioned at the base of the arms of the guiding pole, and is attached to the attachment rope. In this position, when the heaving line is flung from a vessel towards the Y fork, the monkey-fist of the heaving line will pass through or above the Y fork and the heaving line will land on either of the arms and slide downwards to the base of the arms. When the heaving line is tight ened, the monkey-fist at the end of the heaving line will move upwards and be guided to enter the line trap of the line-engaging means.
  • the line-engaging means is releasably attached to the Y fork so that when the heaving line is pulled further, the line-engaging means becomes disconnected from the guiding pole and follows the heaving line to the vessel.
  • the line-engaging means When the heaving line is pulled back to the vessel, the line-engaging means is released from the guiding pole and, along with the attachment rope at tached to it, is pulled to the vessel, where the at tachment rope can be attached to the vessel.
  • the rope-handling system comprises a guiding pole and line- engaging means, but additional components may be in cluded .
  • a winch may be responsible for releasing the attachment rope in order for it to be heaved to the vessel.

  • the winch may hold the attachment rope at a desired length during towing or other connection of a special purpose craft and an assisted vessel.
  • the winch may reel the attachment rope back to the special purpose craft at the end of towing.
  • the winch may be movable or stationary.
  • the attachment rope may be detachable from the winch so that a regular bollard may be used for longer-term mooring of the vessel.
  • the winch may be covered by a housing which protects the winch.
  • One winch may comprise one or two drums. If a winch comprises two drums, each of the drums may be covered by its own housing, or the two drums may share a housing.
  • a winch housing may addi tionally be formed into or comprise structures that help aligning the attachment rope suitably for the other components of the current rope-handling system.
  • An attachment rope may also be comprised in the system according to the present disclosure. Many designs for an attachment rope are known to the skilled person, who is able to select a suitably structured attachment rope for different applications.
  • An attachment rope typically has a loop or another type of attaching means at its free end to facilitate the attachment of the attachment rope to the vessel being connected to the special purpose craft or to the land structures.

  • the upper part may move vertically, while some parts of the guiding pole remain stationary.
  • the guiding pole may be telescopic. In the extended position, the upper end of the guiding pole is higher than in the retracted position. In the retracted position, the guiding pole may be entirely under the supporting surface. However, in some embodiments, the guiding pole may be designed to remain partially above the supporting surface also in the retracted position. In one embodiment of the system, the guiding pole is retractable completely under the supporting surface.
  • the supporting surface may be a deck of a special purpose craft, or a surface of a land struc ture.

  • the vessel is a large container ship, for example, the heaving line is thrown from a position that is much higher than the Y fork. In such a situation, the di rection of the heaving line when it is being pulled towards the vessel may significantly deviate from hor izontal, and even approach vertical.

For example, it may comprise a partially closed chan nel having an opening extending along the length of the channel, the opening being wider in the direction from which the monkey-fist approaches the line trap, so that the monkey-fist will enter the channel. At the end of the channel, the opening is small enough that the monkey-fist cannot exit the channel, but the heav ing line still fits through the opening.

  • the line trap for catching the monkey-fist of the heaving line comprises a recess for receiving the monkey-fist and a groove opening into the recess for guiding the heaving line .
  • the line trap comprises locking means for releasably securing the monkey-fist to the line trap. This avoids the unintended release of the monkey-fist while the attachment rope is heaved to the vessel, in case the heaving line or the attach ment rope slackens and the orientation of the line- engaging means relative to the attachment rope and/or the heaving line changes.
