Description

Technical Field

[0001] The present application relates to the field of shipbuilding technology, and in particular to a PCTC floating and landing pier positioning device. Background Art

[0002] Floating in the dock is a crucial stage in the shipbuilding process, involving the suspension and positioning of the ship. After the ship is floated, dock positioning is a key step to ensure that the ship is accurately and stably parked at the designated location. For the dock positioning of PCTC ships, Jinling Shipyard adopts the method of "male and female heads" combined with cable cooperation. This method is usually suitable for single-line dock construction, but not very suitable for double-line construction.

[0003] In the double-line construction form, the "wall hanging" method is usually used to position the ship at the pier. This method is relatively complicated to operate, requires more equipment and manpower, and also has certain safety risks. The installation of the "wall hanging" needs to take into account factors such as the structural characteristics of the ship, the center of gravity position, and the layout of the dock to ensure that the ship can be accurately and stably positioned at the designated location.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the positioning method of "hanging on the wall" is difficult to install and highly dangerous. Summary of the invention

DETAILED DESCRIPTION

[0026] Floating in the dock is a crucial stage in the shipbuilding process, involving the suspension and positioning of the ship. After the ship is floated, dock positioning is a key step to ensure that the ship is accurately and stably parked at the designated location. For the dock positioning of PCTC ships, Jinling Shipyard adopts the method of "male and female heads" combined with cable cooperation. This method is usually suitable for single-line dock construction, but not very suitable for double-line construction.

[0027] In the double-line construction form, the "wall hanging" method is usually used to position the ship at the pier. This method is relatively complicated to operate, requires more equipment and manpower, and also has certain safety risks. The installation of the "wall hanging" needs to take into account factors such as the structural characteristics of the ship, the center of gravity position, and the layout of the dock to ensure that the ship can be accurately and stably positioned at the designated location.

[0028] In view of the above-mentioned related technologies, the inventor believes that the "wall hanging" method for positioning is difficult to install and highly dangerous. In order to solve the PCTC floating pier positioning problem under double-line construction, the present application provides a PCTC floating pier positioning device.
