Marine surveyor professional bodies

Marine surveyors provide the independent technical assessments that underpin ship transactions + insurance claims + regulatory compliance. Professional societies certify surveyor competence; the major bodies + their specialisations differ substantially. This directory covers the 15 major professional societies.

Marine surveying is one of the strongest post-sea career pathways for ex-officers. Career entry typically requires: Class 1 CoC + 5+ years' senior sea-time + IIMS/SAMS/NAMS diploma or accreditation + peer-review process. Pay is variable based on specialisation, region, and client mix.
