Recently, HGTECH has built a new energy shipbuilding demonstration base project that integrates R&D and design with intelligent manufacturing. The project has been awarded the title of "Smart Shipyard" and has become a benchmark in the global intelligent manufacturing field.

01 Green Transformation of the Shipbuilding Industry

Driven by global environmental protection and low-carbon goals, promoting the transformation from traditional diesel ships to green and sustainable power has become an inevitable trend. This transformation not only meets the requirements of global green development, but is also a key step to improve transportation efficiency and reduce carbon emissions.

However, traditional shipbuilding has many drawbacks: disordered ship types, uneven construction quality, processes that cannot meet the requirements of green shipbuilding, and heavy reliance on manual labor, which makes production efficiency fluctuate greatly. In addition, the shipbuilding process is complex, with a huge number of raw materials and formed components, high discreteness, and great management difficulty, which easily leads to waste. These problems seriously restrict the development of the shipbuilding industry, and intelligent transformation and upgrading are urgently needed.

02 HGTECH Smart Factory for New Energy Shipbuilding

Against this backdrop, HGTECH has designed and implemented the project of "Full-Process Smart Factory for New Energy Shipbuilding Base". It has innovatively applied self-developed high-end equipment such as laser cutting equipment, laser hybrid welding equipment, and full-format multi-head scribing and coding equipment, and adopted a number of self-developed new-generation information technologies including intelligent cutting line generation and recognition technology, intelligent mixed nesting technology, weak-feature high-precision recognition and positioning technology, AI + vision-based intelligent sorting system, yard management system, intelligent central control system, and digital twin system. This has realized the full-process intelligentization and minimal human involvement covering the entire workflow from steel material inbound/outbound, yard storage, loading/unloading, scribing, cutting, sorting, logistics transfer, panel assembly and welding, small assembly fitting and welding to longitudinal member fitting and welding.

03 Green Shipping with AI-Driven Manufacturing

AI Vision Sorting System

Integrated with 3D vision and an AI-based intelligent contour recognition algorithm, the system can accurately locate each part and perform precise follow-up grabbing even in complex industrial environments and among a large number of workpieces with different shapes. It can easily identify part kerfs as narrow as less than 1mm, with an accuracy rate of over 99%, and its sorting efficiency is twice that of traditional manual sorting.

AI Intelligent Welding

The small assembly fitting and welding production line adopts the automatic assembly and spot welding technology pioneered in the shipbuilding industry. Based on the welding model database, the software automatically calls up process parameters, independently plans the optimal welding path and heat input parameters, with a welding qualification rate of up to 98%. The panel assembly and welding production line adopts longitudinal member high-speed positioning and segmented intelligent welding, achieving an ultra-fast welding speed of 2.3m/min, and the assembly and welding cycle is 3 times faster than manual operation.

· Hull-component production efficiency up by 50%
· Overall design efficiency up by 10%
· Operating costs down by 20%
· First-pass product qualification rate up to 95%
· Energy consumption per unit output down by 15%
· Key equipment numerical control rate above 95%
· Data acquisition rate above 98%

As a world-leading provider of intelligent manufacturing solutions, HGTECH is committed to continuously enhancing its manufacturing capabilities centered on intelligent equipment and full-link digital management through high-end technology leadership, intelligent empowerment, and sustainable development. In the future, HGTECH will continue to increase investment in technological R&D, promote the application of new technologies and new processes in the shipbuilding field, and help the global shipbuilding industry move toward higher value-added development.
