Take a look at the focal points from Ocean Business 2025 below, featuring the launch of unmanned maritime technologies ranging from communications to imaging, demonstrations and announcements of autonomous underwater vehicles, brand new sensors and advanced payloads, and much more.
OceanAlpha Unveils L42 USV at Ocean Business
OceanAlpha has introduced its latest innovation in maritime autonomy at Ocean Business 2025 with the launch of the L42 Uncrewed Surface Vessel (USV). Designed to meet the evolving demands of large-scale offshore surveys, the L42 emphasizes operational endurance, modular payload integration, and field-proven reliability.
At the core of the L42’s capabilities is a hybrid propulsion system enabling over 1,500 km of operational range, equivalent to 8 days of continuous mission endurance at 4 knots. This extended range significantly minimizes retrieval frequency, enabling persistent offshore missions without compromising data acquisition schedules.
Greensea IQ’s Autonomous EverClean Robot at Ocean Business 2025
At Ocean Business 2025, Greensea IQ debuted its EverClean Inspection Robot, a standalone, commercially available solution engineered specifically for underwater inspections. It is built on the same reliable platform as the EverClean hull cleaning robot, offering a dependable option for ship operators, service providers, ports, and infrastructure managers seeking consistent, repeatable in-water inspection capabilities.
Fitted with integrated cameras, ultrasonic thickness sensors, and forward-looking sonar, the robot delivers both visual and structural assessments of submerged assets. It is purpose-built to capture data that supports maintenance scheduling, asset health monitoring, and compliance with regulatory requirements.
Advanced Navigation’s Integration Station at Ocean Business 2025
During the trade show, Advanced Navigation provided hands-on experience for marine professionals working across subsea, surface, and autonomous marine platforms, including those operating ROVs, AUVs, USBLs, or INS. These private, technical consultations were designed to provide actionable advice tailored to clients’ current navigation setup.
Visitors were encouraged to bring details of their existing systems to receive guidance on optimizing interoperability, solving sensor integration challenges, and enhancing overall performance. Whether upgrading from legacy systems or planning a next-generation deployment, the Integration Station will help simplify the path forward.

Boxfish Robotics at Ocean Business 2025
Boxfish Robotics showcased its latest innovations in Autonomous Underwater Vehicles (AUVs), aiming to strengthen marine exploration capabilities by enabling fully autonomous, tetherless operations. These advanced AUVs support a wide range of marine applications, from deep-sea research to environmental monitoring, with minimal human intervention.
Wavefront Systems Unveils Mobile Underwater Security Unit
Wavefront Systems launched its new mobile underwater security unit, integrating the Sentinel IDS® (Intruder Detection Sonar) into a ruggedized, self-contained Expeditionary Trailer to deliver rapid and highly effective underwater surveillance wherever required.
The Sentinel IDS® Expeditionary Trailer is designed to safeguard a wide range of assets with a waterside approach, whether in an ocean, lake, river, or reservoir. These assets include sprawling commercial ports, critical national infrastructure, remote naval bases, and private residences. Built on a field-proven military platform known for its robustness and reliability in demanding environments, the trailer’s self-contained design enables personnel to quickly establish an underwater threat detection perimeter in off-grid locations lacking local infrastructure.
Teledyne Valeport to Launch Self-Calibrating pH Sensor for Ocean Monitoring
Teledyne Marine, in collaboration with ANB Sensors, launched a new Valeport product: a next-generation self-calibrating pH sensor engineered for accurate and reliable long-term pH monitoring in marine environments. This sensor offers a robust alternative to conventional glass electrode solutions, eliminating many of the limitations traditionally associated with pH measurement in oceanographic applications.
Also present at the Ocean Business 2025 trade show were Oceanbotics, Hydro-Tech, Maritime Robotics, ecoSUB, Kraken Robotics, and many more. Watch this space for announcements about next year’s edition of Ocean Business.
