Survey and positioning

DriX – Autonomous Survey Platform

Uncrewed surface vessels (USVs) represent a step-change in offshore survey efficiency. Being an official representative of WAMS Subsea (Brazil) in Europe, we provide access to Exail DriX platforms for high-resolution hydrographic and geophysical surveys.

Capabilities:

  • Multibeam echosounder surveys (MBES)

  • Sub-bottom profiling (SBP)

  • Nearshore and shallow water operations

  • Remote operations via satellite and shore-based control centers

Key Advantages:

  • Reduced offshore costs (no large vessel required)

  • Accepted endurance level (multi-day operations)

  • Low environmental footprint

  • Safe operations in high-risk or restricted areas

  • High data quality compliant with IHO standards

Use Cases:

  • Offshore wind farm site investigation (pre-FEED / FEED)

  • Cable route surveys and landfall corridors

  • Port and harbor hydrography

  • Pipeline and subsea infrastructure inspections

  • Government hydrographic surveys

LBL Beacon Rental & Subsea Positioning

Accurate subsea positioning is critical for offshore construction, ROV operations and survey campaigns. We provide rental of Exail Long Baseline (LBL) arrays to suit shallow and deepwater positioning operations..

Capabilities:

  • LBL beacon supply and configuration

  • Array design and deployment support

  • Integration with USBL / INS systems

  • Calibration and positioning workflows

  • Support for deepwater and complex seabed environments

Applications:

  • ROV and AUV navigation

  • Subsea construction and installation

  • Pipeline and cable lay operations

  • Offshore positioning verification

  • Survey control networks
