Description

Floating body stabilizer and load-out method using the same {VESSEL STABILITY DEVICE AND LOAD-OUT METHOD USING THE SAME}

The present invention relates to a floating body stabilizer for stably performing loadout and a loadout method using the same.

In general, in order to build a ship, a method of preparing a dock on the shore, drying the ship inside the dock, opening the dock to introduce seawater into the dock, and launching the ship is mainly used.

However, in recent years, as the space for constructing a dock becomes insufficient and the cost of dock construction increases, a land-building method of launching a ship by transferring it to a floating dock after drying a ship on land has been developed.

In the above-described onshore drying method, after drying the ship while being placed on top of a support installed on land, using a load out facility installed on a rail, the ship is lifted and loaded out to a floating dock floating in the sea, It is to sink the floating dock and launch it.

In order to move heavy objects by sea, it is common to install load-out rails from a location where the heavy objects are stacked on land to a location of a transport ship, and transport them to a transport ship using load-out facilities installed on the load-out rail. That is, after manufacturing a large heavy object or marine structure on land, the cargo is transported using a heavy load skidway at the quay wall (QUAY). The skid way is installed on land, and the transport ship is also installed to be connected to the skid way installed on land. And, a link beam structure connecting the skidway installed on land and the skidway installed on the transport ship is installed.

On the other hand, in the past, vessel stability was lacking when heavy objects were manufactured on land and then loaded out to a transport vessel. This is because even if the transport ship is moored at the pier, the transport ship repeatedly rises or falls due to waves, and the center of gravity changes continuously due to the weight of the heavy object.

Load-out is performed to move a heavy object 31 such as a ship built by land-building method to the sea, and a skidway 22 is installed between the quay wall 24 and the floating body 10, that is, the floating dock, , A process of transporting the heavy object 31 such as a ship, which is a large offshore structure, by pushing the heavy object 31 on the skidway 22 using a large-capacity hydraulic winch (not shown).

The floating body 10 is where the ship is located when a ship built on land is launched into the sea, and a plurality of grillage beams 11 having a support on which a heavy object 32 is seated on the top are installed at equal intervals, A skid beam (not shown) connected to the skid way 22 is installed at the upper end of the grillage beam 11 . The skid beam and the grillage beam 17 are installed so that they are orthogonal to each other, that is, a plurality of grillage beams 11 are positioned in the transverse direction at the lower end of the skid beam installed in the longitudinal direction. The skid beam and grillage beam 11 installed in this way distribute the load when the ship is moved to the barge.

The concrete mat 21 is for dispersing a concentrated load acting on the land 20 when a heavy object 31 such as a ship moves. When a ship is built on land, the number of halves capable of supporting the load of the hull at the bow/stern is limited, so the ship receives a concentrated load when moving. The concrete mat 21 is installed to distribute the concentrated load phenomenon generated on the land 20 using a pile or the like.

The skid way 22 is installed on top of the concrete mat 21, and the position and number of the skid way 22 are prepared in consideration of the position and number that can be loaded most safely and efficiently. Such a skidway 22 is installed after the floating body 10 is anchored near a land such as a wharf and after fixing the ship with an anchor line and a mooring rope. The skidway 22 is installed on land, and the floating body 10 is also installed to be connected to the skidway 22 installed on land.

The connection bridge 23 connects the skid way 22 installed on land and the skid beam installed on the floating body 10 . On the other hand, since the floating body 10 must maintain the connection even when the floating body 10 rises or descends due to waves no matter how much it is anchored at the pier, the connection bridge 23 is connected to the skidway 22 installed on land. Both ends of the skidway 22 installed on the floating body 10 are hinged by pins, and provided to be inclined as the floating body 10 ascends and descends.
