IMRRA identifies key three vessel operational safety risk factors, statistical and dynamic. Each safety risk factor is broken down and given a numerical weighting.
1. Statistical Risk Factors are vessel criteria that does not significantly vary over time, and are associated with longer-term vessel safety performance. Example data includes:
2. Dynamic Risk Factors arise from safety risk events, their frequency and severity. Dynamic risks can include:
3. Verified Risk Factors are the ‘Human Factors’ critical for ship operational safety. A decline, or improvement in vessel management and operation will have an adverse affect on vessel ratings.
