Live Demo
OceanTech Expo, initiated by Zhejiang University's Ocean College, is purposely created to provide a unique comprehensive site for live demos. A survey ship docked at the Ocean College/Zhejiang University pier, the Zhairuoshan Island Experimental Research Observatory, Zhejiang University’s world class marine research and testing facilities, and open-air, fresh water Ming Hui Lake -- all located either on the Ocean College Zhoushan Campus or within a short boat ride away.
