KPI025 | Passenger injury ratio V4.0

Key Performance Indicator

The KPI represents a ratio between the number of injured passengers reported during embarkation, disembarkation and time spent on board, relative to the passenger exposure hours in the reporting period. By defining the KPI as a ratio, benchmarking is feasible even between different ship sizes. Only ships certified to carry passengers should use this KPI. Note that supernumeraries (family members, riding crew, superintendents and stowaways) are not considered as passengers.

Interpretation	This KPI expresses the company’s ability to protect passengers from injury. The indicator does not take into account the severity of injury.
Notes	A fatality resulting from an injury will be counted as a case (as an injury).
Unit	Cases/Million Hours
Scope	Ship level
Calculation period	Quarterly

Formula

[formula]KPI025 = \frac{PI045}{PI061 \times 10^{-6}}[/formula]

PI045	Number of passengers injured
PI061	Passenger exposure hours

Ranking calculation example

Step 1: Calculate KPI value

PI045	Number of passengers injured	= 5
PI061	Passenger exposure hours	= 100000
[formula] KPI025_{Value} [/formula]	[formula] = \frac{PI045}{PI061 \times 10^{-6}} [/formula]	[formula] = \frac{5}{100000 \times 10^{-6}} [/formula]	[formula] = 50 [/formula]

Step 2: Calculate percentile rank by comparing KPI value against other ships with the same criteria. We assume that another 99 (100 in total) participate in the ranking with the same criteria and our ship has position 33 and you are the only ship in that rank.

Step 3: Calculate the percentile rank by capturing the count of all participant below your rank (cl). The frequency of ships in your same rank (fi). The total number of ships in the ranking segment (N).

[formula] KPI025_{Percentile Ranking} = \frac{cl+05*fi}{N} * 100 = \frac{67+0.5*1}{100} * 100 = 67.50 [/formula]

Interpretation: Based on the above example, we could say that, when it comes to KPI025 Passenger injury ratio, this ship belongs in the 67.50th percentile of the ships that are being compared with based on its ranking criteria in the respective quarter.
