Inland hazardous cargo ship safety evaluation offsetting factors analysis

Based on the safety evaluation model, risk offsetting factors of the dangerous cargo ship are analyzed. Correlation algorithm of the control factors of the maximum accident rate offset and algorithm of comprehensive offsetting factors are given. Combined with statistical analysis of inland ship accidents, the differences between the value of the inherent risk evaluation and the real risk evaluation have been compared. According to data analysis, the curves between each offsetting factors and safety evaluation values are obtained. The ship risk evaluation is determined accurately. The negative feedback mechanism of the ship safety management to the risk has been obtained.
