Description

Entry method and departure method of ship

The present invention relates to a method for entering and departing a port for a ship.

Ships can be raised above water for construction, launching, repair, remodeling, and painting using dry docks, floating docks, slipways, and shiplifts. A dry dock is a rectangular pool of water dug deep into the land, with a lock at the front to block seawater. A dry dock closes the lock, drains the seawater inside the dock using a drainage pump, and places a stern within the dock, draining the seawater outside using a drainage pump, allowing the ship to be moored on the stern.

A floating dock is a structure that floats on the sea surface and consists of a bottom wall and side walls. After the dock is lowered into the water, a vessel is anchored on top of the dock. The dock can float together with the vessel. The floating dock includes a tank that can inflow and outflow water, allowing the inflow and outflow of water to be controlled, thereby adjusting the submersion depth of the dock.

Slipway refers to a method of pulling a ship up an inclined plane using a hoist such as a winch.

A shiplift is a device that mechanically lifts a vessel from underwater to the surface. It includes a platform, a structure that supports the vessel's weight and moves up and down. The platform is lowered into the water, and after the vessel enters the platform, it is raised to the surface by a hoist, such as a winch.

As ships can grow in size depending on their intended use, expansion of the platforms used for dry docks, floating docks, and shiplifts is necessary. However, dry docks and other facilities are difficult to expand in size.

The present invention was created to solve the problems of the prior art as described above, and the purpose of the present invention is to provide a method for allowing a large vessel to enter or depart from a dock without expanding the dock size.

A method for entering a port of a vessel according to one aspect of the present invention comprises: a first step in which a vessel moves along an extension of at least one of the left and right quay walls of the dock by a tugboat connected to the vessel at a distance of 60 m or less from the entrance of the dock; a second step in which the vessel is turned by the tugboat at a distance of 40 m or less from the entrance of the dock and is positioned along an extension of a center line of a receiving space of the dock; a third step in which the vessel is connected to a towing device arranged on the quay wall and the connection between the vessel and the tugboat is released; a fourth step in which the vessel is connected to a pulling device arranged on the quay wall at a distance of 20 m or less from the entrance of the dock; and a fifth step in which the vessel enters the receiving space by the towing device and the pulling device.

Specifically, the tugboats may be connected to the front and rear of the vessel, respectively.

Specifically, in the third step, the tugboat connected to the front of the vessel can be disconnected.

Specifically, the towing equipment may be connected to a forward fixing part formed in the bow direction of the vessel, and the pulling equipment may be connected to a rear fixing part formed in the stern direction of the vessel.

Specifically, the tugboat connected to the rear of the vessel can be disconnected after the vessel enters the receiving space.

Specifically, the entrance to the dock may be closed after the vessel enters the receiving space.

Specifically, the vessel may be an underwater vessel of 3,000 tons or more.

Specifically, the tugboat may include a first tugboat; and a second tugboat having a lower directional force than the first tugboat.

Specifically, the connecting means connecting the first tugboat and the vessel can be connected to the vessel through a shackle.

A method for launching a vessel according to one aspect of the present invention comprises: a first step in which a vessel is connected to a towing device arranged on a quay wall of a dock and a pulling device arranged on the quay wall; a second step in which the vessel is positioned at the entrance of the dock by the towing device and the pulling device; a third step in which the vessel is positioned on a centerline of a receiving space of the dock; a fourth step in which the vessel and a tugboat arranged at a position spaced apart from the entrance of the dock are connected and the vessel and the pulling device are disconnected; and a fifth step in which the vessel and the towing device are disconnected.

Specifically, the fifth step may be such that the connection between the vessel and the towing equipment is released when the vessel is separated by more than 5 m from the berth.

Specifically, the towing equipment may be connected to a forward fixing part formed in the bow direction of the vessel, and the pulling equipment may be connected to a rear fixing part formed in the stern direction of the vessel.

Specifically, the vessel may be an underwater vessel of 3,000 tons or more.

Specifically, the third step may include a step in which the vessel is connected to a guide unit installed on the quay wall after the vessel is placed on the centerline of the receiving space of the dock.

Specifically, the third step may include a step in which, after the vessel is connected to the guide section, the pulling device is disconnected from a rear fixing section formed in the stern direction of the vessel and connected to a central fixing section formed in the center of the vessel.

Specifically, the third step may include a step in which the vessel moves toward the entrance of the dock by the towing equipment and the pulling equipment after the pulling equipment is connected to the central fixing part.

The ship entry and departure methods of the present invention have the following effects.

The method of entering and departing a ship according to the present invention can reduce the risk of accidents to the ship by controlling the movement of the ship within a narrow dock.

Figures 10 to 20 sequentially illustrate a method of entering a port of a ship according to the second embodiment of the present invention.

Referring to Fig. 10, a vessel (1) according to a second embodiment of the present invention may be an underwater vessel of 3,000 tons or more. The vessel (1) according to the second embodiment of the present invention may be connected to a first tugboat (T1) and a second tugboat (T2) before entering a dock (2). Specifically, the first tugboat (T1) and the second tugboat (T2) may be connected to a front fixing part (11) and a rear fixing part (13) of the vessel (1). Specifically, the first tugboat (T1) may be arranged forward and rearward in the longitudinal direction of the vessel (1). The first tugboat (T1) may be arranged parallel to the longitudinal direction of the vessel (1). The first tugboat (T1) may pull the vessel (1) in the longitudinal direction of the vessel (1). Two or more first tugboats (T1) can be arranged, and each can be connected to the front fixing part (11) and the rear fixing part (13).

The second tugboat (T2) may be arranged in the lateral direction of the vessel (1). The second tugboat (T2) may be arranged in the lateral direction of the vessel (1). The second tugboat (T2) may pull the vessel (1) in the lateral direction of the vessel (1).

In addition, the second tugboat (T2) can pull the vessel (1) in the left and right directions. The above second tugboat (T2) can maintain force so that the ship (1) is positioned on an extension of the center line in the width direction of the accommodation space (22).

Referring to Fig. 14, the vessel (1) can maintain a distance of 40 m or less from the entrance of the dock (2). The connecting device (4) can transmit a connecting means (L) connected to the pulling device (5) to the vessel (1). For example, the connecting means (L) connecting the pulling device (5) and the vessel (1) can pass through a shackle (14) and be connected to the rear fixing part (13). At this time, the shackle (14) can be arranged to face the front of the vessel (1). The vessel (1) can be connected to the pulling device (5) arranged on at least one of the left and right quay walls (23). The pulling device (5) can pull the vessel (1) in the opposite direction to the second tugboat (T2). For example, the second tugboat (T2) can pull the vessel (1) from the right side, and the left pulling device (52) can pull the vessel (1) from the left side of the vessel (1). The first tugboat (T1) connected to the rear fixing member (13) can pull the vessel (1) to prevent the vessel (1) from approaching the dock (2).
