Problems solved by technology

[0003] However, building a large-scale dry dock requires high construction costs and a large land area, and even after completion, a large-scale dry dock still requires high operating costs
Therefore, it is impossible to construct a large-scale dry dock as required
Furthermore, it is quite difficult and wasteful to maintain and operate multiple large-scale drydocks due to the inability to guarantee a constant shipbuilding order volume

Embodiment Construction

[0023] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] Fig. 1 is a conceptual top view schematically showing a method of building and launching a ship according to the present invention. The unit blocks manufactured in the individual hull production processes are transported to the hull section assembly point 10 and assembled by welding into hull sections 12 for each part of the hull. As shown in Figure 1, the unit blocks are assembled into two hull sections, eg a bow section and a stern section. However, the number of hull sections can be increased to 2 to 4 if desired. 2 to 4 hull sections simplifies transportation and increases utilization of hull section assembly points, thereby increasing productivity of ship construction. In other words, when the hull sections 12 of each part of the ship are assembled at the hull section assembly point 10, the assembled hull sections are transported to...

Abstract

Provided is a method for building a ship on the ground and launching a ship using a skid launching system. The method includes dividing the ship into two through four sections and semi-assembling the divided sections into hull blocks in a hull block assembly yard on the ground, fixing a barge at a quay wall adjacent to the hull block assembly yard in a longitudinal direction, transporting the semi-assembled hull blocks to the barge in a longitudinal direction, completing a hull by assembling the semi-assembled hull blocks on the barge, moving the barge to a launching point and sinking the barge through ballasting, and launching the built ship and floating the barge. Therefore, large-scale ships can be constructed without a dry dock facility while improving the efficiency of shipbuilding.

Description

technical field [0001] The present invention relates to a method of building a ship on the ground and launching a ship using a slipway launching system, and more particularly, to a method of building and launching a ship wherein 2 to 4 parts of the ship are on the ground and Rather than being built in a dockyard, the final vessel is assembled on and launched from barges. Background technique [0002] Ships of small size are built on the ground and then launched into the sea. However, in large-scale shipyards, ships are usually built in dry docks and then the completed ships are launched by filling the dry docks with water. Each section of the hull is divided into unit blocks, each of which is manufactured individually. The finished unit blocks are transported to the dry dock and assembled by welding to complete the entire hull. After the hull is assembled, the assembled boat is floated by filling the dry dock with water, and the boat is towed out of the dry dock and launc...
