Problems solved by technology

Among them, due to the limited diving depth of the semi-submersible barge and the limited water level depth of the launching ground, there are certain requirements for the floating draft of the launching ship. Ships exceeding the draft requirements cannot use the semi-submersible barge to launch normally, and need to be replaced. The semi-submerged barge or the depth of the launching ground will be deepened accordingly, which makes the launching requirements of the ship higher, increasing the cost and difficulty of ship construction

Abstract

The invention discloses a ship launching method, comprising the steps: step S100, installing airbags at the positions on the left and right sides of a ship; step S200, moving the ship to a cargo deckof a semi-submersible barge; step S300, the semi-submersible barge moving the ship with the airbags installed to a launching position for launching operation. By installing the airbags on the left andright sides of the ship, the ship can be provided with auxiliary buoyancy when the ship is launched, so that the draught depth of the ship is reduced, and the submerged depth of the semi-submersiblebarge, and the water depth requirement for the launching position are effectively reduced, the ship can be launched normally by virtue of the semi-submersible barge, which greatly reduces the cost caused by replacing with a semi-submersible barge with high launching capacity and deep-digging a ship sinking pit when the draught of the ship is deep.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for launching a ship. Background technique [0002] In the shipbuilding process, launching a ship is an important step in the entire shipbuilding project, and it is also a test for the shipyard. At present, the product ship after the completion of the platform line needs to use steel brackets as the hull support, use the ship moving trolley to move the ship to the semi-submerged barge, and then use the semi-submersible barge to move the ship to the launching site for launching. Among them, due to the limited diving depth of the semi-submersible barge and the limited depth of the water table, there are certain requirements for the floating draft of the launching ship. Ships exceeding the draft requirements cannot use the semi-submersible barge to launch normally, and need to be replaced. The semi-submersible barge or the corresponding deepening of the depth of the ...
