Hydrographic surveys to acquire seabed data to IHO standards required for navigational, engineering, and design purposes. The data mainly used for:

  • Pipeline and cable route surveys
  • Pre / post engineering surveys
  • Site Topographic characterisation
  • Seabed charting
  • Identification for debris, shipwrecks, subsea structures, coral reefs .etc
  • Dredging support, port and harbour developments and coastal infrastructure

Hydrographic surveys are typically required for:

  • Oil and gas fields
  • Nearshore developments
  • Navigation
  • Ports and harbours

These surveys may include data relevant to:

  • Navigational charts
  • Pre-engineering requirements
  • Dredging support
  • Debris surveys
  • Obstruction avoidance


All charting is utilizing a modern CAD software and the final charts produced extend to the client’s requirements. All charts can be produced in GIS and hard copy.
