Key Performance Indicator

This KPI expresses the company’s ability to avoid environmental related deficiencies.

Interpretation	This KPI is part of a range of KPIs related to deficiencies that are identified during external inspections. The deficiencies are categorized depending on their nature. The number of environmental related deficiencies (PI027) is expressed relative to the total number of external inspections and audits (PI052).
Unit	Number of deficiencies per external Inspection
Scope	Ship level

Formula

[formula]KPI011 = \frac{PI027}{PI052}[/formula]

PI027	Number of environmental related deficiencies
PI052	Number of recorded external inspections

Ranking calculation example

Step 1: Calculate KPI value

PI027	Number of environmental related deficiencies	= 4
PI052	Number of recorded external inspections	= 2
[formula] KPI011_{Value} [/formula]	[formula] = \frac{PI027}{PI052} [/formula]	[formula] = \frac{4}{2} [/formula]	[formula] = 2 [/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 23 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] KPI011_{Percentile Ranking} = \frac{cl+05*fi}{N} * 100 = \frac{77+0.5*1}{100} * 100 = 77.50 [/formula]

Interpretation: Based on the above example, we could say that, when it comes to KPI011 Environmental deficiencies, this ship belongs in the 77.50th percentile of the ships that are being compared with based on its ranking criteria in the respective quarter.
