L42
Marine Survey USV with Range-Extended Electric Powertrain
L42 USV: Engineered With Surveyors,
Perfected for the Oceans
Born from years of direct feedback from global survey teams, the L42 USV (launched in 2025) is OceanAlpha’s most powerful and versatile unmanned platform to date.
Designed in close collaboration with end-users, it redefines efficiency, safety, and data quality in marine operations—delivering unmatched performance without unnecessary complexity.
Redundant Propulsion & Power
The L42 redefines resilience with four independent electric outboard motors + two 20 kW diesel generators—a dual-layer system that delivers silent, precise low-speed control and sustained high-power output.
If any motor or generator fails, the remaining units maintain essential navigation and emergency return capabilities, ensuring uninterrupted operations in harsh conditions.
Multi-Day Continuous Deployment
For long-range survey missions, the L42’s optimized energy management and lightweight design enable 8-day operations at 4 knots or a maximum range of 810nm.
This eliminates frequent port stops for refueling/recharging, reducing operational costs and time constraints for large-scale maritime coverage.
61+ Device Compatibility: Built for Any Mission
The L42 USV shatters payload limits with a modular interface—able to integrate 61+ device types from 21+ leading brands (including Kongsberg) across 10+ sensor categories, far outpacing typical USVs’ compatibility and eliminating reconfiguration hurdles.
Advanced Control:
Tailored for USVs, Built to Perform
Developed specifically for USV operations, OceanAlpha’s in-house USV control system eliminates third-party limitations, ensuring faster updates, tailored functionality, and long-term reliability you can trust.
