The 2025 Zhuhai international Smart Marine Expo will be held with great fanfare at the Zhuhai international Airshow Centre from 24th to 26th April 2025.
With a focus on the new mission and tasks of marine economic development, and under the theme of "Sci-Tech Innovation for a Smarter Ocean", the 2025 Zhuhai international Smart Marine Expo will comprise three main sections exhibitions, conferences, and associated activities. The Expo aims to establish an international marine exchange platform that fosters open cooperation and mutual benefit. lt aspires to be a comprehensive exhibition showcasing the unique characteristics of the ocean theme, integrating upstream and downstream industry chains, intelligent technology applications, and industry-academia collaboration. This platform is designed to enhance the overall strength of the marine economy, stimulate innovation, and promote sustainable development. it will inject fresh momentum into strengthening the marine economy comprehensively, revitalising the blue economy, and accelerating the development of the marine industry in the Guangdong-Hong Kong-Macao Greater Bay Area.
This year's exhibition is expected to attract over 200 enterprises specialising in marine intelligent and unmanned equipment, ocean renewables, intelligent ships, marine anti-corrosion and new materials, marine ranching and deep-sea aquaculture equipment, yachts, island development, and tourism. The planned exhibition area is 30,000 square metres.
「Nanjing Zechang Aviation Technology」

Independentlv developed domestically produced digital expendable ocean temperature/sound velocityprofile direct measurement probes XBT/XSV
The XBT enables rapid, cost-effective temperature-depth profiling by integrating temperature and depth sampling directly into the probe, leveraging digitization to achieve ±0.05°C temperature accuracy and ±0.5% depth precision. The XSV directly measures sound speed profiles using a Time-of-Flight (ToF) method, delivering real-time data with ± 0.25 m/s accuracy. Unlike methods that derive sound speed indirectly from temperature and salinity data, XSV’s direct measurement significantly improves accuracy in high-salinity or salinity-fluctuating zones, enhancing sonar propagation models and acoustic positioning systems. These probes are deployed across marine surveys, deep-sea research, and anti-submarine warfare (ASW) operations, offering reliability in extreme conditions while reducing deployment complexity.
Physics-based Marine Environment (Flow Fields, Waves, Meteorological Conditions, etc.) Equipment-Environment Complex Coupling Simulation
This marine engineering software series integrates innovative algorithms to enable high-efficiency numerical simulations. The numerical wave tank uses 5th-order WENO and 3rd-order TVD schemes with the Level Set method to model 6-degree-of-freedom floating body motion and parallel computing. The fluid-structure interaction platform boosts computational speed by 10,000x using AI-powered graph neural networks, achieving sub-meter resolution. The pollutant diffusion software combines weather and terrain data for real-time dynamic predictions. Together, these tools enhance algorithm innovation, computational performance, and real-world engineering applications, driving advancements in marine equipment development, environmental risk management, and intelligent upgrades for industrial software ecosystems.
ntelligent satellite communication products
This product series integrates advanced communication and intelligent video processing technologies, offering robust video compression, transmission, and multimodal communication capabilities. It employscontinuous variable bitrate asymmetric gain deep video compressionandpacket-loss-resistant pyramid-structured narrowband compressionto enable efficient video transmission and storage. Optimized for satellite video signal adaptation, the system supports hybrid communication modes (narrowband, broadband, satellite, terrestrial) and applies to satellite communications, low-altitude economy, IoT, and emergency response. It delivers intelligent, efficient, and reliable communication and video surveillance solutions across defense, industrial, and civil sectors.
