The SL40 autonomous survey vessel is a cutting-edge unmanned craft designed for hydrographic and bathymetric assessments. With dimensions of 1.6 meters in length and 0.7 meters in width, this vessel weighs 35 kg and can accommodate up to 15 kg of survey equipment.
Featuring an advanced waterjet propulsion system, the SL40 can navigate at speeds of 5 m/s while effectively avoiding entanglement with aquatic vegetation or debris. it is equipped with an obstacle detection system and Real-Time Kinematic (RTK) positioning, allowing for control via a base station or remote device.
① quick Transition Between Tasks
Instruments such as Acoustic Doppler Current Profilers (ADCPs), echo sounders, and side scan sonars, ranging from 5 cm to 18 cm in diameter, can be swiftly installed in the central moonpool, facilitating seamless mission transitions.
· ADCP
· Echo Sounder
· Side Scan Sonar
② Multibeam Echo Sounder Upgrade
Beyond the standard instruments, the SL40 can be enhanced with a multibeam echo sounder solution, which has demonstrated remarkable reliability and performance through extensive testing.
The optional multibeam echo sounder models include the R2sonic 2020 and Hydro-Tech YH400P.
③ Automated Mission Configuration
Survey missions can be pre-configured with just a few clicks on the base station interface. The SL40, equipped with the necessary instruments, can autonomously conduct surveys and transmit real-time data back to the operator.
for challenging areas, the SL40 can also be manually operated using a remote controller.
④ Smart Collision Avoidance
With integrated radar sensors, the SL40 can identify obstacles and avoid collisions within a 50-meter radius.
In manual operation mode, users can monitor the aquatic habitat through real-time video feeds, enhancing navigation safety.
⑤ Enhanced Speed & Tangle-Free Operation
The innovative waterjet propulsion system enables the SL40 to reach a maximum speed of 5 m/s while effectively preventing entanglement with aquatic plants or debris.
⑥ Superior Stability in navigation
The trimaran hull design significantly enhances stability, notably during high-speed travel.
