  • Device and a method for tying and untying a tug line at a ship
    Patent number: 5732647
    Abstract: A device and a method for engaging and disengaging of a towing line from a tow boat to and from a ship. At the ship there is a hawse hole (5), a bollard head (1) and a working for inhauling of a messenger rope (4), attached to the lop of the towing line (3). The device is especially characterized in that a guide means, like a hook (2), is attached to the ship in such a way, between the bollard head (1) and the working (7), so that the messenger rope (4) guided by the second guide means (2) can pull the loop of the towing line (3) near and above the bollard head (1) so that this easily can be engaged around the bollard head (1), whilst the messenger rope (4), free from the second guide means (2), by the working (7) can lift the loop inwardly, up above the bollard head (1) so that the towing line can be taken on board by the tow boat.
