OceanTech International Symposium and OceanTech Program (OT)

With the support of the IEEE OES Shanghai Chapter and SUT China Branch, OceanTech International Symposium has been launched as part of an expansion initiative of the national conference in 2019.

The China Ocean Technology Conference and the newly launched OceanTech International Symposium form part of an umbrella program -- OceanTech Program -- that unfurls into an exhibition, co-located conferences, technical seminars, workshops, and live demonstrations. Networking events include a guided tour for delegates to visit some of the most important ocean facilities in Zhoushan. OT Talent Club also taps into the OT resource to foster career development for China’s rising stars.

The OceanTech Program is an international showcase of the latest know-how & live demos, conceived and realized by China’s own ocean community. It is a unique opportunity to meet with old customers, exchange new idea, build new contacts, promote new products, find distributors and learn the latest developments in China through networking with the nation’s ocean community.

Why Zhoushan?

The OceanTech Program (OT 2023) will once again be hosted at Ocean College, Zhejiang University (Zhoushan Campus).

Zhoushan, China’s largest archipelago and one of the nation’s leading port cities, is a popular tourist destination in Zhejiang Province. It is home to Ocean College, Zhejiang University.

In addition to Zhejiang University, Zhoushan’s local government has established collaboration with Beijing University, Shanghai Jiaotong University, as well as the Chinese Academy of Sciences.

With State Council’s approval to establish Zhejiang Zhoushan Islands District on 2011, it became the fourth national level new economic zone and the first with such status to build a marine economy, serving as China’s strategic oceanic window to the world.

Zhoushan’s key industries include: port and navigation services, ocean technology equipment, marine engineering equipment and shipbuilding, marine tourism, marine sourced energy production, marine mining and mineral extraction, marine biotechnology and modern marine fisheries.

Ningbo-Zhoushan port recorded 1.12bn tonnes of cargo throughput in 2019, ranking it as the world’s busiest port for the eleventh consecutive years. Its newly upgraded multi-modal transportation service, capable of handling large-size vessels, supports the increasing cargo handling demands. With its shipping and port infrastructure advances in place, and role as China's bunker hub, rivalling global players such as port of Singapore, it is emerging as a top-class world port.

Zhoushan is one of the leading ship repair bases in China, hosting facilities for shipping giants such as Cosco. In 2018, the yards in Zhoushan repaired around 2,000 ships, accounting for 20% of the nation’s total ship repair volume.

OceanTech Program (OT 2023) Venue – Zhoushan Campus, Zhejiang University


Ocean College, Zhejiang University (Zhoushan Campus), is located on China’s largest archipelago and in one of China’s leading port cities - Zhoushan, Zhejiang Province.

It has nine research institutes and one research center which include Institutes of Ocean Engineering and Technology, Marine Geology and Resources, Marine Chemistry and Environment, Marine Biology and Pharmacology, Physical Oceanography and Remote Sensing, Port, Waterway and Offshore Engineering, Marine Structures and Naval Architecture Engineering, Ocean Sensing & Networking, Ocean Electronics Engineering & Intelligent System and the Maritime Logistics and Free Trade Islands Research Center. It has also established the Zhejiang University Ocean Research Institute and Zhejiang University Advanced Technology Research Institute Zhoushan ocean Branch. 

Ocean College focuses on China’s national strategic objectives in resources, environment, sovereign rights and deep oceans, and, the local science and technology needs in Ocean Engineering Equipment, Environmental Protection Technology, Deep Ocean Equipment and Resources Exploration Technologies, Marine Safety Assurance Technologies, and Marine Environment Monitoring and Restoration. The college benefits from its location in Zhoushan, a unique ocean environment, and Zhejiang University’s multidisciplinary structure. Ocean College strives to build a premier national ocean science education and talent base.

Ocean College’s banner meeting, China Ocean Technology Conference, attended by China’s top academic members and international scholars, is conducted biennially in May. In 2021, the 5th China Ocean Technology Conference has co-located with the OceanTech Exhibition. Sixth events -- to be held May 19 - 22, 2023 -- will be part of OceanTech program, aiming to stage the latest technological advancements and to facilitate the growth of China’s ocean technology industry in its strategic oceanic window to the world.

About Together Expo Limited

As the Middle Kingdom’s Initiatives deepen to integrate the region’s economies through advancing infrastructure and tighter and broader exchanges, Together Expo’s role to engage the business and public communities worldwide culminates when the OceanTech Program (OT) was launched in May 2019.

Since its incorporation in 1992, Together has organized shows covering an array of sectors – wherever more sophisticated technology is needed to modernize China’s own industries. As China became the World Factory, energy and resources were vital to the country’s growth, Together consolidated its resources into the energy fields to stage up Asia’s premier China Coal & Mining Expo and China’s only national scale geology show.  Both Together Flagships are hosted in the capital Beijing.

As China emerged as a global investor and cross-border venturer, Together captured the change, and has now entered into the ocean that connects all the continents of the world.
