Lemvos – Automated subsea infrastructure surveillance 

Due to their critical nature, the monitoring of subsea cables and pipelines has become a matter of national interest. Historically, these infrastructures have largely been unmonitored. However, recent acts of sabotage have prompted governments to consider ways of monitoring and protecting these vital assets.

Lemvos has developed an automated, GNSS-guided, satellite-connected Unmanned Surface Vessel (USV) for monitoring subsea infrastructure. Equipped with high-resolution sonar imaging, the system enables 100% remote monitoring in harbour and offshore environments. This technology plays a crucial role in securing valuable subsea assets of national importance, such as cables and pipelines, by providing reliable, continuous surveillance.

Benefits:

• Ability to increase efficiency, scalability and cost savings for subsea monitoring, while reducing environmental impact and safety risks.
• With semi-autonomous capabilities, a single operator can manage multiple USVs simultaneously, significantly expanding coverage compared to traditional crewed vessels.
• Remote operation eliminates travel time and the DockMaster system automates deployment, reducing downtime and maximising productivity.
• Fuel and CO₂ emissions are significantly reduced due to the compact, crew-free design of the vessel.
