BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a mooring apparatus which automates mooring of vessel to vessel, or vessel to quay by mechanical operation.
BACKGROUND OF THE INVENTION
The prior art has conventionally carried out mooring operations of vessel-to-vessel, or vessel-to-quay using the following procedures; vessel respectively, and a chief manager positions himself at a steering house of the vessel, quay) as seen in FIG. 2, a rope is thrown to an opposite side from the stern, and the opposite party hauls it (the rope is combined at its end with a mooring bridle 100), is combined (such as by a knot) with a bitt 101 (or a bollard), end and mounted on a winch 102 of the vessel A at its other end, and it is coiled by a required amount, and the work at the stem is finished, of a big vessel, the bridle 100 is also provided at its center besides the stem and stern).
As is seen, the mooring work requires much labor and time. The wire rope is, in general, used for the bridle. The wire rope is easily handled, but it is often broken several times in a year per vessel. The mooring work is very dangerous. Therefore, automation of the mooring operation has been desirous from the view of improving the work and safety of the workmen.
The present invention is to provide a mooring apparatus which automates the above mentioned mooring work by means of mechanical operation.
DISCLOSURE OF THE INVENTION
For accomplishing such an object, the invention is, as shown in FIG. 1, constructed by providing a rotatable crane 5, equipping a bitting part 2 to a mooring bridle 1 at its end portion which is coiled by a winch 3, and connecting a cable 4 suspending the bitting part 2 to the crane 5 so that the bitting part 2 is moved vertically by rotation of the coiling mechanism 53 of crane 5. The bitting part 2 is caught by the bitt or bollard at the opposite vessel or quay.
When carrying out the mooring work, the bridle 1 is loosened by releasing the winch 3, and the crane 5 is rotated with respect to the object bitt and the suspending cable 4 is allowed to go down to a desired position from the crane 5. In this way the bitting part 2 is mounted on the bitt. Subsequently the suspending cable 4 is loosened, while the mooring bridle 1 is coiled up by the winch 3 to effect a tension thereto. Thus the mooring work is accomplished.
When the vessel leaves from the opposite vessel or quay, the bridle 1 is loosened by releasing the winch 3, and the cable 4 is pulled up by the crane 5 to draw back the bitting part 2 from the bitt.
Further, in the invention, the mooring winch 3 is rotated in association with the rotatable crane 5 in order to prevent breaking of the bridle 1 by excessive twisting caused when coiling the bridle 1, thereby to enable coiling efficiency.
