On December 10, 2025, LDI, in collaboration with MindChip OÜ, participated in a live demonstration as part of the Digimaris project, highlighting cutting-edge Finnish-Estonian marine spill-response services. The trial took place at Hundipea Harbor in Tallinn, the base of the Estonian Riigilaevastik (State Fleet), and gathered representatives from private industry, government ministries, and marine environmental organizations from both Estonia and Finland.
Real-Time Oil Spill Detection with ROW Sensor
During the event, LDI showcased the ROW oil-spill sensor integrated onto a mobile uncrewed surface vessel (USV), demonstrating its ability to detect, track, and monitor oil spills in real marine environments. The ROW sensor operates by detecting changes in fluorescence signals at the water surface.
Wireless data collected via a remote radio modem revealed distinct signal spikes corresponding to oil contamination, clearly separated from the baseline seawater signal. This confirmed the sensor’s high sensitivity and reliability in real-world conditions.
Enhancing Spill-Response Readiness Through Digitalization
The demonstration highlighted the significant impact of autonomous platforms and real-time sensing on national spill-response readiness. By integrating the ROW sensor into a USV, operators received immediate contamination alerts and could visualize the movement of oil spills in real time. This allows for faster decision-making and minimizes environmental impact, crucial in sensitive marine areas.
Proven Performance in Harsh Conditions
Despite the cold temperatures and variable weather at Hundipea Harbor, the ROW sensor delivered stable, high-quality data with consistent sensitivity. Its ability to capture clean fluorescence signals in a dynamic marine environment underscores its suitability for both research and operational oil-spill monitoring.
Cross-Border Collaboration and Future Innovation
The trial also emphasized the importance of cross-border collaboration between Estonia and Finland in protecting shared marine environments. LDI continues to work with partners to expand autonomous detection capabilities, refine data-analysis workflows, and support next-generation oil-spill response systems.
LDI is proud to contribute to innovative, environmentally focused solutions and remains committed to advancing autonomous marine monitoring technologies.
