Technical Capabilities

Our subsea operations leverage a sophisticated blend of acoustic and inertial technologies. We don't just find locations; we define them through rigorous multi-path analysis and sensor fusion.

LBL & USBL Positioning
Long Baseline (LBL) arrays for high-precision local grids and Ultra-Short Baseline (USBL) for dynamic vessel-to-target tracking. Integration of Sonardyne and HiPAP systems.
Structure Installation
Real-time monitoring of manifolds, templates, and umbilical deployments. Metrology services for precise "hub-to-hub" connections.
Subsea Structural Surveys
As-built surveys and integrity inspections using multi-beam echosounders and photogrammetry overlays.
