With A-level production license, the business covers a full range of products for shipbuilding and installation gantry cranes, which have withstood the test of harsh working conditions and high utilization rate of equipment, and have proprietary slewing ring upper and lower flange surface processing technology, which can be customized according to needs.
The tugboat line ranges from 5,000HP to 8,000HP with specialized capabilities. Notable models include the first Robert ship-type tug in Shandong Province (5,000HP), China's first full-slewing oil spill recovery tugboat (6,000HP), and the 8,000HP full-slewing Z-type propulsion tugboat—currently China's largest horsepower port multi-functional tugboat with port pushing and offshore engineering construction capabilities. The 70-ton towing full-slewing tugboat meets international advanced standards for port towing and fire protection.
The container vessels feature advanced intelligent systems including 5G network, WiFi wireless hotspot, enhanced lookout, AI behavior recognition, cabin patrol check-in, ship energy efficiency analysis, navigation dynamic analysis, driving assistance decision-making, and autonomous navigation. Equipped with low-voltage shipborne shore power systems achieving zero emissions at port berth, the vessels handle ordinary containers, refrigerated containers, and dangerous goods with dual functionality as container and dry cargo ships.
The leveling dredger is the first self-elevating working ship globally combining both underwater rubble foundation bed leveling and dredging functions. This patented innovation has won a national invention patent and the second prize of scientific and technological progress from China Port Association. The electric propulsion large backhoe dredger is China's largest and deepest, featuring both self-propelled and trolley towing functions, recognized as Shandong Province's first set of technical equipment in 2021.
The deep-sea intelligent cages feature double-layer mesh modular fully enclosed design with small piece mesh and low creep nets, reducing deformation and enhancing safety. The automatic feeding system supports semi-submersible and full-submersible bottom culture. A comprehensive security monitoring system uses video surveillance and AI image recognition with 90%+ prediction accuracy for early warning of aggressive animals. Multi-parameter sensors based on optoelectronic integrated chip technology enable long-term, low-cost accurate monitoring of marine ranching environments.
The shipbuilding gantry cranes with A-level production licenses range from 50-ton to 200-ton lifting capacities with spans up to 105 meters. Equipped with proprietary slewing ring upper and lower flange surface processing technology, these cranes withstand harsh working conditions with high equipment utilization rates. The product line covers manufacturing, installation, transformation, and maintenance services, fully customizable to specific shipyard requirements.
