Haoye Technology Shines at Shanghai OA Marine Expo, with Multiple Core Technologies Attracting Attention​

From October 22 to 24, 2025, the 3rd International Marine Science and Technology Equipment Exhibition (OA 2025 Marine Expo) was grandly held at the Shanghai Cross-border Procurement Exhibition Center. This industry event, which gathered over 200 exhibitors worldwide and attracted more than 5,000 professional visitors, served as a core platform to showcase the cutting-edge capabilities of marine science and technology. Tianjin Haoye Technology Co., Ltd. made a heavyweight appearance with six core products—underwater steering gears, underwater push rods, T561 Thrusters, T581 Thrusters, 324 Power Sections, and RT10 Rim Thrusters. Relying on its independently innovative technological advantages and full-scenario adaptability, the company aroused enthusiastic attention.

As a "specialized, refined, distinctive, and innovative" enterprise deeply engaged in the entire industrial chain of underwater power systems, Haoye Technology’s product matrix exhibited this time fully covers key fields such as underwater power control and propulsion drive, demonstrating its core R&D strength in the "three-in-one" system of "controller-permanent magnet motor-fluid power". Among the products, the T561 Thruster stood out for its full-sea-depth operation capability. Adopting magnetic coupling transmission technology to achieve contactless transmission, it can operate stably under voltage fluctuations and has passed 3,000 hours of fatigue testing, making it an ideal power choice for underwater equipment such as AUVs (Autonomous Underwater Vehicles) and ROVs (Remotely Operated Vehicles).

The T581 Thruster, which complements the T561, attracted much attention for its multi-functional integration features. With its technological advantages, it can demonstrate the dual characteristics of low-noise operation and high-efficiency power output in deep-sea detection equipment. The publicly exhibited RT10 Rim Thruster inherits the technical genes of Haoye’s RIM series. It adopts an integrated design of permanent magnet motor and propeller, abandoning the traditional transmission shaft system, and realizes 360° omnidirectional propulsion and absolute zero-leakage sealing. It is not only suitable for the side thrust and main propulsion needs of small and medium-sized ships within 40 meters, but also supports deep-sea operations at 11,000 meters. Its compact structure and ultra-light weight give it significant advantages in the auxiliary thrust scenario of underwater robots.

In the field of power control and transmission, the underwater steering gears and underwater push rods exhibited by Haoye Technology also sparked extensive discussions. Both products adopt military-grade protection standards, have passed IP67 waterproof, dustproof, and salt spray resistant certification, and can achieve precise control in harsh marine environments ranging from -10°C to 40°C. Together with the thruster series, they form an integrated "power-control" solution, adapting to multiple scenarios such as marine observation and underwater engineering. The 324 Power Section, launched to meet the needs of high-power equipment, relies on Haoye’s technical accumulation in the power system of 1,000-ton class unmanned submersibles, achieving breakthroughs in power density and lightweight design, and providing stable power support for large underwater platforms.

At the expo site, Haoye Technology’s booth was always crowded with people. Professional visitors from domestic and foreign marine-related universities, research institutes, and marine engineering enterprises stopped to consult one after another. During exchanges with marine experts, the independent degree and performance stability of its products were highly recognized.

As a high-tech enterprise, Haoye Technology’s participation in this expo not only demonstrated the innovative breakthroughs of China’s underwater power equipment, but also fulfilled its corporate mission of deeply participating in the marine power strategy. In the future, Haoye Technology will continue to focus on the fields of deep-sea equipment and green ship power, injecting Chinese strength into the global development of marine science and technology.
