Oceanalpha Visit Website

Oceanalpha is a leading developer of Unmanned Surface Vessels (USV), offering USV solutions for a number of applications, including: water quality sampling & monitoring, flow measurement, hydrographic survey, oceanographic research, security patrol, search & rescue, and maritime missions.

Oceanalpha Unmanned Sufface Vessels

Featuring advanced intelligent technology, Oceanalpha autonomous boats and unmanned surface vessels 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 USV solutions to meet the requirements of our customers.

Environmental Monitoring Unmanned Surface Vessels

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.

ESM30 Autonomous Water Sampling & Monitoring Boat

ESM30 Unmanned Surface Vessel

The ESM30 is an autonomous water sampling & monitoring unmanned surface vessel designed to provide a fast response to sudden water pollution accidents in difficult or challenging environments, and to conduct water sampling tasks in lakes, rivers or reservoirs.

The ESM30 autonomous surface vessel uses GPS location tracking to follow preset waypoints and mission parameters, navigating autonomously while intelligently avoiding obstacles up to 10m ahead. It can integrate third-party probes, such as YSI, hydrolab and eureka, for online data acquisition and the creation of water quality contour maps.

Hydrographic Surveying Unmanned Surface Vessels

ME40 Unmanned Surface VesselHydrographic surveys measure the physical features of seas, lakes, rivers and other bodies of water, and are often conducted to ascertain how these features will affect navigation, construction, exploration, oil and gas drilling and other maritime activities.

Our Unmanned Surface Vessel survey platforms can greatly accelerate hydrographic data collection, requiring less manpower and cutting down on costs.

SL20 Autonomous Hydrographic Survey USV

SL20 Autonomous Hydrographic Survey Unmanned Surface Vessel

The SL20 autonomous survey boat is a compact and portable unmanned surface vessel (USV) for hydrographic and bathymetric surveys. Its moon pool supports flexible deployment of different instruments, including ADCP and echo-sounders. Made from carbon fibre, the SL20 measures 1 meter long and weighs 17 kg, and can be easily operated and transported by one person. Its powerful battery and low power consumption ensures 6 hours of endurance while sailing in 3 knots.

SL40 Autonomous Hydrographic Survey USV

SL40 Autonomous Hydrographic Survey Unmanned Surface Vessel

The SL40 autonomous survey boat is a waterjet-propelled unmanned surface vessel (USV) for hydrographic and bathymetric surveys. Measuring 1.6 meters long and 0.7 meters wide, the SL40 weighs 35 kg and can carry 15 kg of survey instrumentation. The innovative waterjet propeller allows the USV to sail at 5m/s and effectively avoid being entangled in water plants or rubbish. The USV comes with obstacle avoidance system and RTK, and can be controlled by either a base station or a remote control.

SL40 Hydrographic Survey USV Specifications:

Dimensions1650 x 700 x 400mm
Weight 35kg
Max Speed10 knots (5m/s)
Remote Control Range1km
Data Telemetry Range2km

ME40 Autonomous Hydrographic Survey Boat

ME40 Hydrographic Survey Autonomous Boat

The ME40 is a hydrographic survey unmanned vessel constructed with a trimaran hull design for stable sailing and a shallow draft that allows it to survey reefs and areas close to shore with its single-beam sonar. The in-built inertial navigation system allows it to provide accurate real-time survey data.

The ME40 unmanned boat greatly improves the flexibility and efficiency of bathymetry surveys, and is widely used in reservoirs, lakes and tailing ponds removing humans from potentially hazard  situations.

ME40 Unmanned Boat Specifications:

Dimensions1360 x 710 x 420mm
RF point to point range5km
Max Speed
Remote controller range2km

M40 Catamaran Oceanographic Survey USV

M40A Catamaran Oceanographic Survey Unmanned BoatThe M40 is a medium size autonomous survey unmanned platform, designed for bathymetry surveys in coastal areas and oceans. With a modular catamaran design and flexible payload for instruments, the M40A unmanned surface vessel was developed to provide high performance surveys with single or multi beam sonars, as well as different kinds of hydrographic and monitoring instruments.

The M40 has an aluminum and carbon fiber hull and is powered by a high capacity lithium polymer battery.
