The manufacturing process of a ship mainly includes the following steps:
Steel pretreatment: First, the steel plate is hoisted onto the roller by an electromagnetic crane, and then passed through equipment such as a leveler and a heating furnace to remove surface moisture and rust, and then sprayed and dried.
Material processing: According to the design drawings, the steel plate is cut into the required shape and size. This step is the basis of shipbuilding.
Assembly of parts and components: Assemble the cut steel plates and other parts to form the various parts of the ship.
Sectional welding: Weld the assembled parts to form the segmented structure of the ship. This step is a key link in shipbuilding and involves a lot of welding work.
Slipway welding (closing): The segmented structure is finally welded and closed on the slipway to form a complete hull structure.
Wire boring: Accurately measure and adjust the hull to ensure accurate docking of each part.
Ship launching: After the hull construction is completed, the ship is put into the water for preliminary testing and inspection.
Power generation vehicle: Test the ship's power generation system to ensure its normal operation.
Main vehicle: Test the ship's main engine system to ensure that it can start and operate normally.
Mooring test: Conduct a comprehensive system test on the ship at the dock, including inspections of navigation, communication, safety, etc.
Sea trials: Conduct a comprehensive sea trial in open waters to test the performance and stability of the ship.
Completion and delivery of the ship: After all tests and inspections are completed, the ship is officially delivered for use.
The modern shipbuilding model is characterized by greater specialization. Modern shipyards mainly carry out general assembly work, while other professional work such as segment processing and system component manufacturing are completed by specialized subcontractors. This model improves production efficiency and quality control.
