About Us

Yantai Huahong Diving Engineering Co., Ltd. was originally established in 2000. Its predecessor was a diving engineering team formed by naval divers who had retired from the military. In 2012, the company integrated several other diving engineering teams. After years of accumulating technical expertise and fostering a strong corporate culture, it officially registered and became a specialized company engaged in marine engineering, commercial diving services, underwater salvage operations, and the R&D of underwater equipment for marine engineering projects. Since its establishment, the company has carried out nearly 10,000 underwater engineering projects for clients in industries including oil, shipping, port management, water conservancy, power generation, municipal services, and offshore aquaculture cage farming—both domestically and internationally. Among these, its core businesses of underwater inspection of vessels and underwater cleaning of marine organisms from ship hulls have experienced steady and consistent growth over the years, earning unanimous praise from both domestic and international clients.

Focusing on deep-water safety and jointly building an emergency safety defense line: The Beijing International Emergency Expo | 2026 International Diving Safety Technology and Equipment Exhibition—co-organized by institutions from three countries.

Nov 14,2025

Against the backdrop of globally coordinated development in disaster prevention and emergency response and the rapid advancement of underwater safety technologies, the "Beijing International Disaster Prevention, Mitigation, and Emergency Safety Industry Expo—2026 International Diving Safety Technology Equipment Exhibition," jointly organized by relevant agencies from the Republic of Turkey, the Russian Federation, Beijing Zhongsheng International Exhibition Co., Ltd. of China, and other related entities, will be held with great solemnity from June 26 to 28, 2026, at the Shougang Convention and Exhibition Center in Beijing. This industry event, jointly created by institutions from three countries, will showcase the latest technological achievements in global disaster prevention and mitigation as well as diving safety. The Beijing International Emergency Expo will serve as an important platform for international cooperation among disaster prevention and emergency response enterprises. Unlike traditional disaster prevention and emergency expos, this year’s expo uniquely focuses on the specific field of “diving safety technology.” Whether it’s underwater rescue operations during flood disasters, underwater inspections of reservoirs and dams, safe operations in marine engineering, or precise preservation of underwater archaeological sites, all these areas place extremely high demands on the safety, reliability, adaptability, and intelligence level of diving equipment. Meanwhile, real-world needs such as life support in complex aquatic environments, efficiency of emergency rescue operations, and safety in deep-water operations have also made advanced diving safety technology equipment a focal point of industry attention.
