IMRRA Methodology

The following key risk factors are identified, assessed, given a numerical weighting:

Statistical Risk Factors

Vessel criteria that does not significantly vary over time, and are associated with long-term vessel risks. Static risk factors are based on the following example information:

  • Casualty History & Incidents
  • Classification Society Performance
  • Company Operator Performance
  • Insurance claim history
  • Vessel Particulars

Dynamic Risk Factors

that rise from changes in their frequency or severity – not just a desktop survey! Dynamic risk factors are derived from variable information such as:

    • Crew proficiency
    • Inspection Reports
    • Port State Control & US Coast Guard
    • Safety inspections & reports from industry databases
    • Self-test audit reports
    • Terminal’s feedback


Verified Risk Factors

IMRRA’s prediction tool. Analysis of collected data indicates improvement, or decline, in vessel operation and management. The ‘Human factor’ when assessing risk:

  • Verified RA information
  • Vessel Operator Verification audits
