  • Kongsberg EM 2040 Series Multibeam System

    HD Foundation Imaging

    Ultra-narrow beams (0.4°×0.7°) + 200-700kHz agility deliver cm-resolution bathymetry and backscatter—clearly identifying scour, marine growth, and micro-topography changes for structural assessment.

    Adaptable to Any Platform

    Four models (C MKII, P MKII, MKII, EM 2042) cover vessels, USVs, ROVs, and AUVs—for any depth or foundation type.

    3D Beam Stabilization

    Real-time roll, pitch, and yaw stabilization ensures precise targeting in complex currents

    Multi-Freq Seabed Classification

    Single-pass multi-frequency captures sediment data, distinguishing scour pit materials—key for evolution analysis and protection assessment.

    Real-Time Water Column Monitoring

    Full water column data detects bubble seepage and fish aggregation—supporting environmental monitoring during construction and operation.

  • Sagsea Series Fiber Optic Inertial Navigation Unit

    High-Precision Attitude & Heave

    Heading accuracy ≤0.05° secφ, attitude ≤0.01°, real-time heave 5cm or 5%—delivering stable, precise vessel motion data for multibeam systems to ensure true-to-life imaging of foundation terrain and scour holes.

    All-Source Navigation, Seamless Switching

    Integrated GPS, BeiDou PPP, and RTK with auto-switching between satellite and pure inertial modes—maintaining continuous high-precision positioning even in turbine-shadow or signal-drop zones for full 360° pile coverage.

    Modular Split-Body Deployment

    IMU supports independent subsea mounting; deck unit integrates GNSS receiver—adaptable to survey vessels, ROVs, and USVs for flexible inspection of piles, pipe racks, and suction anchors.

    Large-Capacity Full Data Logging

    Built-in 32GB storage records complete inertial data. Post-mission tight-coupling processing (e.g., POSPac) further refines pile inspection accuracy, delivering reliable data for millimeter-scale deformation analysis.
