Description

Apparatus for Transporting a Mooring Rope and Floating Structure Including the Same The present invention relates to an automatic rope conveying device and a floating structure including the same. Ships or offshore structures are typically moored to quays or similar structures using mooring ropes. In this case, the mooring rope extends from the ship or offshore structure to the quay or similar structure and can be secured by being hooked onto a mooring post. Conventionally, mooring operations, which involve securing mooring ropes to mooring posts, are performed by workers directly grasping the ropes extending from vessels or offshore structures and moving them toward the posts. Since mooring ropes carry considerable weight, it is very difficult for workers to move them, and the risk of injury from safety accidents caused by the ropes increases for those performing the mooring process. Typical safety accidents occurring during mooring operations include ropes snapping due to high tension, resulting in worker fatalities or injuries, or snapback accidents where severed ropes destroy surrounding structures such as vessels. Recently, new regulations are being established to restrict workers from directly moving or handling mooring ropes and to prohibit the use of equipment to operate them. Therefore, there is a growing need for an automatic rope transfer device and a floating structure incorporating it to comply with newly changed regulations while preventing safety accidents during mooring operations. FIG. 1 is a conceptual drawing illustrating a floating structure according to one embodiment of the present invention. Figure 2 is a drawing illustrating an automatic rope conveying device. Figure 3 is a drawing showing a rope wound on the coiling unit of a storage winch. Figure 4 is a diagram showing the rotation of the roller section when the rope is in the unwinding state, being transported toward the support structure. Figure 5 is a diagram showing the rotation of the roller section when the rope is in a wound state being transported to the opposite side of the support structure. Hereinafter, specific embodiments for implementing the technical concept of the present invention will be described in detail with reference to the drawings. In addition, in describing the present invention, if it is determined that a detailed description of related known components or functions may obscure the essence of the invention, such detailed description is omitted. Furthermore, when it is mentioned that one component is 'connected,' 'transferred,' or 'placed' on another component, it should be understood that while it may be directly connected, transferred, or placed on that other component, there may also be other components present in between. The terms used in this specification are used merely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. Furthermore, it should be noted in advance that expressions such as "upper side," "lower side," and "side" in this specification are described based on the drawings, and may be expressed differently if the orientation of the object changes. For the same reason, some components in the attached drawings may be exaggerated, omitted, or schematically depicted, and the size of each component does not entirely reflect its actual size. Additionally, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but such components are not limited by such terms. These terms are used solely for the purpose of distinguishing one component from another. The meaning of "comprising" as used in the specification is to specify certain characteristics, regions, integers, steps, actions, elements, and/or components, and does not exclude the existence or addition of other specific characteristics, regions, integers, steps, actions, elements, components, and/or groups. Hereinafter, the specific configuration of a floating structure (1) according to one embodiment of the present invention will be described with reference to FIGS. 1 to 5. Referring to FIG. 1, the floating structure (1) is installed to float at a designated location on the sea, for example, a location with frequent ship traffic, and can provide a space for an electric vessel in operation to moor. The floating structure (1) may be configured to have propulsion capable of navigation. For example, the floating structure (1) may be a ship or a floating body. Additionally, the floating structure (1) may include an automatic rope transfer device (10), a hull (20), and a rope (30). A support structure (2) can be connected to and supported by the floating structure (1) so that the floating structure (1) can be moored.
