OceanAlpha’s L25 USV achieves long-range survey milestone in Malaysia
In late June 2025, OceanAlpha’s L25 marine uncrewed surface vehicle (USV) successfully completed its first public demonstration in Malaysia, showcasing its advanced marine survey capabilities in real-world conditions at Port Klang. The event, attended by over 60 maritime industry leaders, marked a significant step forward for autonomous survey operations in the region.
The L25 USV directly addresses critical constraints for offshore marine surveys: crew dependence and the costly support vessels typically required for operations beyond the line-of-sight (LOS) control range. By successfully conducting a survey mission 33 kilometres offshore while maintaining continuous, stable satellite communications and real-time payload data transmission, the L25 validated reliable over-the-horizon (OTH) capability, which is essential for large-scale or remote survey areas.
Mission adjustments from shore
In the congested waters of Port Klang, the vessel’s advanced perception systems enabled autonomous navigation around moored vessels while dynamically adjusting course to maintain safe distances from high-speed marine traffic. The L25’s integrated automated towfish system demonstrated seamless deployment and retrieval of sidescan sonar equipment, eliminating traditional manual winching requirements and reducing operational risk.
The event also highlighted the L25’s ability to transmit multibeam, sidescan and sub-bottom profiler data in real time, allowing survey teams to conduct immediate quality control and mission adjustments from shore. This capability significantly reduces decision-making timelines for marine survey operations.
The demonstration was made possible through collaboration with key industry partners, including the Malaysian Maritime Department, which facilitated operational approvals. Tara Advisory co-hosted the event, leveraging its expertise in autonomous systems to ensure practical validation of the L25’s capabilities. Technical partners including TA Geosolutions, Hidrokinetik Technologies and Clockwise Subsea (NOR Offshore Rental) contributed specialized equipment and regional operational expertise.
Addressing critical survey pain points
“Following the successful demonstration of our L25 in Dubai this May, we are pleased to bring another L25 USV to south-east Asia and validate how OceanAlpha’s autonomous solutions address critical survey pain points,” said Pinestone Shi, general manager of OceanAlpha. “Looking ahead, we will continue to promote our uncrewed surface vessel products and comprehensive solutions worldwide, empowering the marine survey industry to achieve safer, more efficient and cost-effective operations.”
With the L25 USV platform now operational in south-east Asia and the Middle East, OceanAlpha invites interested parties to inquire about technical specifications, demonstration footage or potential applications. The company continues to work with regional partners to advance autonomous marine survey solutions.
OceanAlpha was founded in 2010 as a manufacturer of USVs and has since grown to over 500 staff with offices in mainland China, Hong Kong, Singapore and Qatar. With cutting-edge technology and a robust R&D foundation, OceanAlpha has become a global leader in maritime autonomous industry. Its USV products and solutions are widely applied in water environmental monitoring, hydrographic and geophysical surveys, offshore asset inspection, life rescue, security patrol and more.
