A unique, highly sophisticated, hydrographic survey vessel built for nearshore and coastal applications, Orion boasts many desirable survey vessel characteristics:

  • Hull-mounted multibeam SONAR and state-of-the-art electronics for acquiring data to International Hydrographic Organization (IHO) Special Order standards
  • Moon pool mounting plug (housing the transducer array and the vessel-motion reference unit) placed in the optimal location for the vessel, based on extensive design modeling
  • Fairing for the multibeam array designed into the moon pool plug to minimize acoustic interference across the transducer face
  • Below-deck hydraulics and compressor to support a variety of commercial diving operations
  • A-frame and davit attachments, large working deck, and open transom to support a variety of survey, sampling, and instrument deployment and recovery operations
  • Jet drive system for safe and effective live-boating applications for underwater inspections, pipeline tracking, etc.
  • Trailerable
