Underwater Remote Operated Vehicle

Deploy fast, fly precisely, and get actionable underwater visuals. The SRV-8 is a professional remotely operated vehicle (ROV) designed for real-world operations such as search & recovery, infrastructure inspection, surveillance, and underwater testing. Built for ease of use across operator experience levels, it combines highly manoeuvrable vectored thrusters, intuitive SubNav OS software, and robust power options to help teams complete complex underwater tasks more safely and efficiently.

With rapid set-up, a 305 m depth rating, and hot-swappable battery power (up to 8 hours), the SRV-8 is made for quick-response missions in lakes, rivers, ports, and coastal environments, especially where conditions demand stable control and reliable performance.

Why teams choose the SRV-8

• Rapid deployment: launch from shore, boat, or dock in under 3 minutes.
• High manoeuvrability: eight thrusters support precise positioning and controlled movement in challenging conditions.
• Mission endurance: hot-swappable battery modules provide up to 8 hours of runtime (usage dependent), with an optional topside power system for continuous surface power.
• Operational depth: depth rated to 305 m to support deep inspections and recoveries.
• Customisable capability: plug-and-play add-ons (sonar, navigation, non-destructive testing tools, grabbers/manipulators) allow you to configure the SRV-8 to the mission profile.
