OceanAlpha, a Hong Kong-based innovator in unmanned surface vessels (USVs), has recently demonstrated its L25 model in a series of trials aimed at showcasing the vessel’s capabilities for offshore and maritime subsea surveys. Conducted in Port Rashid, Dubai, from 26 to 29 May 2025, the event featured dynamic demonstrations that underscored the L25’s advanced functionalities. Enhanced by collaboration with partners SINO and Sitech Gulf, these trials highlighted the vessel’s autonomous navigation, sensor integration, and real-time data collection capabilities.
Pinestone Shi, general manager of OceanAlpha, elaborated on the potential of the L25, stating that it can be customised with equipment suited for various applications, including offshore energy production, hydrographic studies, and geophysical surveying. Notably, the L25 is equipped with twin diesel engines that can incorporate additional fuel tanks, thereby extending its operational range for maritime missions. This versatility is increasingly essential in a region where the focus on energy infrastructure and smart port development is paramount.
During the trials, the L25 was fitted with a sophisticated array of sensors, including Teledyne Marine’s T20 multibeam sonar and EdgeTech Marine’s 4125 side-scan sonar, alongside the Teledyne PDS software which significantly enhances data accuracy. According to Shi, the incorporation of Trimble Centrepoint RTX signal correction enabled the USV to achieve an impressive positioning accuracy of 4 cm. Such precision is critical for the demanding requirements of offshore oil and gas operations, as well as marine surveys.
In a broader context, OceanAlpha has initiated a year-long showcase for its USVs throughout the Middle East, starting in Doha, Qatar. This initiative is strategically aimed at sectors including offshore oil and gas, marine survey companies, and maritime enforcement authorities. The showcase intends not only to demonstrate the capabilities of the L25 but also to highlight other models in OceanAlpha’s fleet, such as the M75 uncrewed patrol vessel and the SE40 uncrewed water sampling vessel. The company aims to deliver hands-on experiences, thereby fostering familiarisation with the technology and encouraging adoption across various industries.
The L25 has previously demonstrated its prowess in challenging marine environments as part of a critical survey of subsea pipelines, where it effectively navigated 14 kilometres while surveying 2 kilometres of pipeline. This operation involved navigating waters with depths fluctuating between 0 to 8.6 meters under flow speeds of up to 4 knots, further proving its capabilities in complex conditions.
As the maritime industry increasingly embraces autonomy and digital transformation, the advancements represented by OceanAlpha’s L25 and its offerings reflect a significant shift towards modernisation and operational efficiency. With growing demands for precise data and effective marine monitoring, the integration of USVs is likely to become pivotal in the evolving landscape of maritime operations.
