Comprehensive Survey & Construction Solutions

Vessel & Barge Positioning: Delivering real-time high-accuracy positioning and orientation control for survey vessels, construction barges, lay barges, and jack-up rigs. Subsea Asset & ROV Tracking: Utilizing acoustic positioning systems to track subsea equipment, remotely operated vehicles, and underwater structure placement with pinpoint precision. Anchor Handling & Tug Management: Providing real-time telemetry and navigation guidance for anchor handling tugs during barge mooring and offshore platform operations. High-Precision GNSS Positioning: Deploying multi-constellation RTK and DGNSS setups to establish rigid spatial reference controls for coastal and offshore engineering activities. Pipe & Cable Lay Guidance: Real-time track alignment, touchdown monitoring, and position verification for subsea pipeline, umbilical, and power cable installations.

Current Velocity & Flow Profiling: Deploying Acoustic Doppler Current Profilers (ADCP) to record current speed, direction, and flow distribution throughout the water column. Tide & Sea Level Monitoring: Real-time tracking of tidal cycles, water surface elevations, and vertical datum benchmarking for marine infrastructure and navigation. Wave Climate & Spectral Analysis: Measuring directional wave height, period, energy spectra, and sea state conditions using floating buoys and subsea pressure sensors. Water Quality & Physical Sampling: Multi-depth sea water sampling and continuous monitoring of physical parameters, including salinity, temperature, turbidity, and dissolved oxygen.

Sub-Bottom Profiling: Mapping sub-seabed geological strata, sediment thickness, bedrock profiles, and shallow sub-surface structures. Side-Scan Sonar Imaging: High-resolution acoustic seabed imaging to map seafloor morphology, exposed pipelines, subsea debris, and navigational hazards. Marine Magnetometer Surveys: Detecting magnetic anomalies, buried ferrous targets, subsea pipelines, umbilical cables, and unexploded ordnance (UXO). Geohazard & Site Clearance Investigations: Identifying shallow gas pockets, fault lines, scour features, and sub-surface constraints to derisk foundation and dredging operations.

Subsea Infrastructure Maintenance: Inspecting, cleaning, and servicing underwater assets, including outfall diffuser pipes, intake screens, manifolds, and structural flanges. Marine Growth & Biofouling Removal: Mechanical cleaning, hydro-jetting, and surface preparation for subsea structures, sea chests, and vessel hulls. Survey Mobilization & Custom Fabrication: Designing, welding, and installing specialized over-the-side sensor poles, transducer brackets, and deck winch frames for survey vessels. Cover Plate & Valve Interventions: Mechanical removal, bolt torquing, seal replacement, and re-installation of subsea inspection covers, blind flanges, and flow control gates.
