OceanAlpha is a leading developer of Unmanned Surface Vessels (USV), offering autonomous solutions for a wide variety of marine and maritime applications. Featuring advanced intelligent technology, OceanAlpha’s autonomous boats are used by commercial clients, government organizations, research institutes and universities around the world.

The company’s USV platforms provide enhanced efficiency for waterborne missions and can be used for hydrology research, scientific exploration, hydrographic surveys and inspections, emergency search and rescue, security patrol, fire control and more. OceanAlpha continuously strives to improve its advanced solutions to meet and exceed the requirements of customers.

USVs for Inland & Offshore Surveys

Equipped with state-of-the-art payloads, OceanAlpha’s unmanned survey vessels are ideal for a range of applications in both shallow and deep waters, enabling missions to be completed with greater efficiency than traditional methods.

Offshore Wind Farms
OceanAlpha is dedicated to applying unmanned vessel technology to the offshore wind power sector. OceanAlpha’s marine USVs boast precise positioning and control capabilities, along with nimble maneuverability, enabling them to efficiently carry out planned survey line tasks. Equipped with sensors such as multibeam echo sounders, side-scan sonars, and sub-bottom profilers, OceanAlpha’s marine USVs are capable of effectively gathering critical data for offshore wind O&M, including seabed topography, scour and sedimentation around pile foundations and cables, the precise location of cables, as well as their burial depth and suspended span heights.

Offshore Oil & Gas
OceanAlpha’s high-speed unmanned boats have seen mature application in the offshore oil and gas industry, mainly providing efficient solutions for daily patrols, material transportation, and oil spill detection. The company has also introduced an innovative solution for the autonomous launching and recovery of the USV, facilitating a high level of uncrewed operations for patrolling and material transportation between oﬀshore platforms.

Hydrographic Survey
Unmanned hydrographic survey vessels with advanced payloads such as echosounders, side-scan sonars and ACDPs are used to measure and characterise features such as seabeds and shorelines.

Oceanographic Survey
OceanAlpha’s unmanned vessels are used to profile currents, waves and water columns in all ocean environments from coastal areas to the open seas.

Bathymetry
Autonomous USV bathymetry surveys provide essential depth measurements of lakes, rivers and the seabed, as well as manmade structures such as dams and reservoirs.
