Geophysical surveys is to gather detailed data required by engineers for the installation of offshore structures, subsea cables and pipelines. That data is used to:

  • Map seabed and sub-seabed conditions
  • Profile geological features
  • Detect geohazards
  • Provide a seabed and sub-seabed reference for geotechnical investigations

Geophysical surveys are typically required for:

  • Site surveys for rigs or platforms
  • Route surveys for pipelines or cables
  • Geohazard and fault detection
  • High resolution seismic mapping

Geophysical survey equipment including:

  • Multi-beam and single-beam echo sounders
  • Sub-bottom profilers
  • Side scan sonars
  • Magnetometer

Geophysical survey feature on-board processing and reporting facilities which allows for seamless integration of the data sets which are processed, interpreted, reported and charted offshore.

The deliverables are to meet a client’s specific requirements, and typically include hard and soft copies of:

  • Comprehensive Final Reports
  • AutoCAD / PDF charts

GIS deliverables to OGP/IMCA Seabed Survey Data Model (SSDM) or client specified geo-database schematic formats
