We Love What We Do

They say that when you work in a job doing what you love to do, then it's not work.  And that's how it is at iXblue Australia.  We love planning and undertaking surveys - especially the more challenging projects.

Our core team is comprised of seven highly qualified and experienced Hydrographic Surveyors and a Finance Manager who keeps everything organised and running efficiently. The team's background is in delivering safety and navigation surveys for government bodies, defence, the mining, resources, oil and gas industries.

For large projects or multi project schedules, we have access to the team from our French office and a pool of expert contractors.

More Than the Usual Qualifications

A key point of difference with iXblue is our depth of qualifications and industry certification.  Our team members have obtained the highest possible certifications in the survey industry.

There are two types of education and certification when it comes to the hydrographic survey.

  1. Category A and Category B levels which are awarded after successful completion of theoretical and practical courses devised by IHO / FIG / ICA (International Hydrographic Organization / International Federation of Surveys / International Cartographic Association).  Category A is the highest level.  This is the academic qualification required to undertake survey work.
  2. AHSCP Level 1 and Level 2 certification.  This internationally recognised scheme is provided by the Australasian Hydrographic Surveyors Certification Panel (AHSCP) and jointly sponsored by the Surveying and Spatial Sciences Institute (SSSI) Hydrography Commission and the New Zealand Institute of Surveyors (NZIS) and is only available to qualified Surveyors who have logged considerable field experience.  AHSCP Level 1 certification is the highest level of professional certification that a hydrographer can attain.  The SSSI Hydrography Commission produced a Hydrographer Certification Video to explain what the certification is all about.

Our core team includes four IHO / FIG / ICA Category A trained hydrographic surveyors as well as several Category B surveyors. Each of our Category A Surveyors also hold AHSCP SSSI certification.
