L25 | Unmanned Surface Vehicle丨OceanAlpha

Outstanding Payload Capacity

Wider deck, bigger payload, supporting multiple equipment work simultaneously for underwater inspection, hydrography survey and oceanography survey.

Standard range is 65h@4kns, extendable to 130h@4kns, significantly surpassing similar-sized manned boats.

Small A-frame and winch support towing survey, cable length up to 200 meters;
Foldable lifter protects instruments wet ends and offers greater payload capacity.

Excellent stability，roll range smaller than 10 degrees in SS4.
Catamaran design significantly reduces swaying and spray foam, providing stable and quiet working condition for acoustic equipment
Low noise electric Plug-in thruster, reduces signal-to-noise ratio by 20%

Radar, HD camera and AIS sensing enabling highly sensitive environmental perception
Dual engine and dual propeller providing large torque, L25 can rotate in situ
Able to navigate closely around constructions for zoom-in inspection
Autonomous navigation algorithm, advanced obstacle avoidance algorithm and propulsion control algorithm applied to minimize risk of collision

During a mission, if the L25 loses communication or is about to run out of power, it can automatically sail back to the designated location to avoid getting lost on the sea.
