2026 Asia Deep Sea Development and Subsea Operation Equipment Expo and Trade Fair

Date: December 18-20, 2026 Location: Hainan International Convention and Exhibition Center

[Preface]

Deeply cultivate the blue ocean and empower the future of the deep sea. In order to seize the opportunities of global deep-sea resource development, marine engineering construction, and underwater intelligent operation industry development, and to build a one-stop high-end industry platform integrating technology exchange, product display, commercial docking, and resource integration, and to promote the localization, intelligence, and internationalization upgrading of China's deep-sea equipment industry, Hongwei International Exhibition Group held the Asia Deep Sea Development and Underwater Operation Equipment Expo with the support of government units such as the Hainan Provincial Oceanic Department and the Ministry of Commerce. The exhibition will be held at the Hainan International Convention and Exhibition Center, based on the advantages of Hainan Free Trade Port and the marine industry, radiating across the country, linking with the Asia Pacific region, and facing the world. We sincerely invite high-quality enterprises in the industry to participate in the exhibition and jointly explore the blue ocean market.

This expo is based on the national strategy of building a strong maritime nation, focusing on core areas such as deep-sea resource exploration, underwater engineering construction, deep-sea operation and maintenance, and marine emergency support, and striving to create a highly influential professional event for deep-sea equipment in Asia.

The total exhibition area of the exhibition is 80000 square meters, with a planned 600 participating companies and targeted invitations for 35000 precise professional visitors from around the world. It gathers deep-sea research institutions, engineering construction enterprises, marine energy enterprises, equipment manufacturers, and upstream and downstream supporting service providers.

The exhibition aims to empower the deep sea with technology and lead the future with equipment, showcasing cutting-edge technologies and innovations in deep sea development both domestically and internationally

Equipment and overall solutions, breaking down barriers between industry, academia, research, and application, helping enterprises expand into the Hainan Free Trade Port and Southeast Asian deep-sea engineering market, and empowering high-quality development of the marine economy.
