About Dongyu

Sichuan Dongyu Information Technology Co., Ltd. specializes in the research and application of machine intelligence and Internet of Things (IoT) technologies. The company’s independently developed marine biofouling prevention system utilizes the ultrasonic cavitation effect to physically and effectively inhibit the attachment of marine organisms to the surfaces of ships and offshore facilities. Compared to traditional chemical anti-fouling methods, it offers significant advantages such as zero chemical emissions and no release of microplastics. It complies with environmental regulations set by organizations such as the International Maritime Organization (IMO) and effectively reduces navigational drag and fuel consumption. Currently, the system has been widely adopted in fields such as ship anti-fouling, offshore platforms, offshore wind power, and seawater pipelines.
