On October 30th, the 16th International Shipbuilding, Marine Equipment and Offshore Engineering Exhibition for China was held at the Dalian World Expo Center. This year's exhibition, with the theme 'Gathering the Achievements of the Industrial Chain • Promoting High-Quality Development,' brought together both upstream and downstream players of the maritime industry, establishing a cooperation platform for technical exchanges, product displays, and business transactions to empower the quality upgrading of the maritime industrial chain. Our university was invited to participate in the opening ceremony and a series of other events and showcase representative achievements in a stand-alone exhibition booth.

In his opening speech, Zhao Youtao, Vice President of our university, stated that currently, Liaoning is at a critical stage of transitioning towards a maritime economy and accelerating new breakthroughs in revitalization. This period also presents an important opportunity for Dalian to promote the transformation and upgrading of its modern maritime industry system and achieve high-quality development of the pilot area for industrial structure optimization and the pilot area for economic and social development. The 16th International Shipbuilding, Marine Equipment and Offshore Engineering Exhibition for China has provided a comprehensive, multi-level platform for exchange and cooperation in the maritime industrial chain. It is an important exhibition and practical measure in response to national strategies, supporting the revitalization of Liaoning, and serving the development of Dalian.

During the conference, our university and the Dalian branch of China Classification Society signed a framework cooperation agreement for the qualification of new marine technology products. The two parties will conduct in-depth cooperation in the qualification of new marine technology product, including concept verification, prototype validation, system integration verification, real ship application qualification, etc.

Xiao Fengke, Director of the Products Department of China Classification Society Dalian Branch, presented to our university's Marine Engineering College the Qualification Certificate for the Marine Online Intelligent Lubricating Oil Contamination Monitoring System. This system employs advanced technology to achieve real-time and online monitoring of lubricating oil contamination, thereby enhancing the operational efficiency and safety of ships.

Our university's representative achievements are showcased in a stand-alone exhibition booth.

Introduction to the Achievements on Display

1. Key Technologies for Zero-Carbon Port Energy and Their Applications

In response to the significant demand for low-carbon technologies in port energy, Professor Ma Xiangkun's team has developed an intelligent microgrid system for wind-solar-hydrogen storage in ports and an energy management system with multiple energy sources. The team has also developed collaborative optimization technologies for port equipment cluster operation and energy efficiency improvement, as well as energy recovery control technologies. Notably, they have made breakthroughs in large-scale, high-safety, long-life flow battery energy storage technology. This achievement can meet the energy needs of ports in the "storage-transportation-refueling-utilization" cycle, reduce carbon emissions, and improve operational efficiency, providing a technical guarantee for the realization of "zero-carbon ports." It has also driven the green and safe development of China’s port and shipping industry, bringing significant social and economic benefits.

2. Full-Ocean-Depth Research Winch System

The deep-sea research winch system is used for the launching and retrieval of deep-sea survey instruments and is fundamental for research vessels. Supported by the National Key R&D Program of China during the 13th and 14th Five-Year Plan periods, Professor Li Wenhua's team, in collaboration with industry partners, successfully developed China's first full-ocean-depth geological winch system, capable of operating at a maximum depth of over 11,000 meters. This system achieved a breakthrough by obtaining samples at a depth of 7,762 meters for the first time. The research team has also completed the integration test of the full-ocean-depth optical cable winch system and is soon to conduct sea trials aboard a vessel, providing reliable support for China's marine scientific research endeavors to "venture into the open ocean, delve into the deep sea, and explore the polar regions."

3.High-Quality Marine Simulators

The high-quality marine simulator series encompass full-mission ship handling simulators, radar simulators, ECDIS simulators, GMDSS simulators, interactive tugboat simulators, and more. The functionalities of the system fulfill the requirements for crew training and assessment stipulated in the STCW Convention, the Training Syllabus for Seafarers of Sea-going Ships of the People's Republic of China, and the Standards for Competency Assessment of Seafarers of Sea-going Ships of the People's Republic of China. Notably, the full-mission ship handling simulator has obtained the highest-level (Class A) certification from DNV GL (Det Norske Veritas Germanischer Lloyd). These products cater to a diverse range of training needs, including crew training, pilot training, VTS operator training, GMDSS radio operator training, as well as other specialized training programs. Additionally, they can be utilized for scientific research such as port and waterway engineering evaluations and testing and validation of intelligent marine equipment.

4.Rapid On-site Microfluidic Detection Device for Algae Activity

The Rapid On-site Microfluidic Detection Device for Algae Activity is the only ballast water rapid testing equipment in China with full independent intellectual property rights. It has pioneered the theory of using the relative fluorescence yield ratio of single microalgae to characterize cell activity and established a fluorescence representation model for microalgae activity. For the first time, the dielectric properties of single microalgae cells and the mechanism of AC/DC dielectrophoretic cell motion control are made clear. A precise manipulation and analysis method for microalgae cells based on optofluidic chips is proposed, effectively reducing the time and labor cost of manual identification through microscopes in traditional red tide algae detection, as well as the difficulty in accurately determining algae activity and species. The device enables automatic sorting, quantitative activity detection, and intelligent identification of red tide algae in port waters.

5.The First Fuel Cell Yacht in China, "Lihu"

Our research team has solved technical difficulties such as hydrogen filling for ships, lightweighting of hydrogen cylinder groups, hydrogen-related safety design, marine fuel cell system design, and hybrid system design for ships, relying on years of research outcomes. The fuel cell yacht designed on this basis is 13.9 meters long, using a 70KW fuel cell and an 86KWH lithium battery to form a hybrid power system. The design speed is 18km/h, with a range of 180km and a capacity of 10 passengers. The ship type and power are close to the foreign benchmark ship, while the most critical endurance indicator for electric ships has a slight advantage. The trial voyage has verified the practicality of fuel cells as a power source for ships, and the smooth, quiet, and comfortable operation of the hull has also confirmed fuel cell’s unique development advantages in yachts and other ship types that require high level of user experience.
