It is a leading domestic provider of underwater robot products and solutions, and a high-tech underwater space exploration company driven by technological innovation. Deepinfar's main business is the R&D, production, sales, and service of products such as cable-controlled underwater robots, autonomous underwater vehicles, underwater gliders, automatic profiling buoys, and underwater booster robots. Anchored in the "deep sea technology" field, it provides products and professional solutions for marine security, marine engineering, emergency rescue, water conservancy and hydropower, marine scientific research, and marine cultural tourism.
Deepinfar is a pioneer in the full-spectrum product R&D of underwater robots in China. After more than ten years of continuous R&D and innovation accumulation, it has focused on underwater robot system technology, underwater power and energy technology, underwater robot control, navigation and communication technology, and underwater robot advanced manufacturing technology. It has mastered 15 core technologies in four major categories, including small and medium-sized autonomous underwater vehicle technology, full-attitude anti-flow motion control technology for cable-controlled underwater robots in complex waters, and underwater high-efficiency high-thrust-to-weight-ratio electric propulsion technology. Relying on the above self-developed core technology system, Deepinfar has built a complete product spectrum covering cable-controlled underwater robots, autonomous underwater robots, and underwater booster robots, becoming one of the few enterprises in the industry with full-series underwater robot independent R&D and large-scale production capabilities.
Deepinfar is a National High-Tech Enterprise, a National Key "Specialized, High-end and Innovation-driven" Little Giant Enterprise, and a National Intellectual Property Advantage Enterprise. It has a postdoctoral research workstation, a Tianjin Enterprise Technology Center, and a Tianjin Key Laboratory of Underwater Intelligent Unmanned Systems. It has won important awards such as the Second Prize of the National Technological Invention Award, the First Prize of the Tianjin Science and Technology Progress Award, the First Prize of the Fujian Science and Technology Progress Award, the First Prize of the Marine Engineering Science and Technology Award, the German Red Dot Design Award, and the German iF Design Award. Deep Blue has participated in 6 National Key R&D Program projects, led or independently undertaken 1 Ministry of Industry and Information Technology special project, 2 national defense special projects, and 5 Tianjin special projects, and presided over or participated in the formulation of 6 national standards and 5 industry standards. As of December 31, 2025, Deepinfar holds 392 domestic and foreign patents (including invention patents, utility models, and design patents), of which 108 are domestic invention patents and 12 are foreign invention patents.
After long-term technological accumulation and market development, Deepinfar has established multi-level and wide-coverage sales channels. Its important customers cover national defense units, marine engineering construction and operation and maintenance units, government emergency management departments, universities and research institutes, etc. Underwater booster robot products have been sold to developed markets in Europe and America, Japan and South Korea, as well as emerging markets in Southeast Asia, totaling more than 80 countries and regions. As a high-tech underwater space exploration company driven by technological innovation, Deepinfar is committed to becoming a leader in the global underwater robot industry, providing solid industrial support for the national "Marine Power" strategy and the localization of high-end equipment.
