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 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 1.22bn tonnes of cargo throughput in 2021, ranking it as the world’s busiest port for the thirteenth 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.

As the China'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.
