Oceanalpha Unmanned Sufface Vessels

Featuring advanced intelligent technology, Oceanalpha autonomous boats are used by commercial clients, government organizations, research institutes and universities across the world.

Our unmanned surface vessel platforms are a reliable way to improve working efficiency on the water and can be used for hydrology research, scientific exploration, hydrographic survey, emergency search and rescue, security patrol, fire control and other tasks. We continuously develop our advanced solutions to meet the requirements of our customers.

Environmental Monitoring

Monitoring the quality of water in rivers and lakes is of great importance to humans and wildlife alike. Conducting manual sampling and surveying of large bodies of water can be extremely challenging and resource-intensive. Our USV platforms vastly reduce the time and effort required to conduct missions that help keep drinking water safe, react to pollution disasters, and conserve wild plants and animals.
