ROUTE CLEARENCE

Our team executes effective PLGR and route clearance operations, crucial for smooth subsea cable installations. We meticulously clear routes for new cable installations, removing any obstacles identified during marine surveys. By eliminating subsea obstructions promptly, such as ropes, lines, and other debris, we ensure seamless installation operations, thus averting unexpected delays. All retrieved items undergo proper sorting and recycling procedures, a reflection of our commitment to environmental responsibility.

SCOUR MONITORING

Scour monitoring is a vital preventive measure to safeguard foundation assets against erosion. Leveraging advanced techniques such as visual inspection, high-resolution multi-beam bathymetry, and side-scan sonar, we meticulously assess scour protection effectiveness and identify potential hazards. Rapid deployment of scour protection mitigates risks, ensuring uninterrupted operations.
