Services

Land and Harbor delivers real-time underwater data solutions, specializing in sales, leasing, and consulting for complex environments. We rely on our experience to select o various sonar technologies with remote sensing methods to develop reliable, reproducible inspection solutions for a wide range of underwater assets including: Piers, Bridges, Dams, Power Plant Intakes, tunnels and pipelines.Sonars and ROVs enhance underwater inspections through remote sensing, enabling us to monitor delta P, water intakes, silt levels, underwater structures, diver safety, detritus, clogged or damaged trash bars, traveling water screens, biofouling, and mammal or fish impingement.

Sonar Imaging and Remote Sensing

Remote sensing inside industrial facilities offers a safer, more efficient alternative to traditional diver-based inspections. By leveraging sonar imaging, we provide high-resolution, real-time data that enhances operational awareness while minimizing risks and downtime.

Machine Vision and Trend Analysis

Land and Harbor transforms raw sonar and visual data into actionable insights with advanced machine vision and trend analysis solutions. By automating defect detection, anomaly recognition, and predictive forecasting, our AI-driven tools enhance accuracy, streamline underwater inspections, and optimize maintenance planning. This technology improves decision-making, minimizes human error, and ensures proactive infrastructure management.
