KPI012 | Failure of critical equipment and systems V4.0

Key Performance Indicator

This KPI expresses the company’s ability to maintain critical equipment and systems in good working condition always.

Interpretation	The KPI counts the number of failures of equipment and systems in the critical list defined in the company's Safety Management System.
Notes	1. This KPI is kept without a denominator because a failure to a critical equipment or system is serious, regardless of how many items a company's SMS has in its list of Critical Equipment. 2. As the ships' critical lists may vary in size it could be argued that e.g. the number of items on the list could be used as a denominator for benchmarking purposes. In any case, a failure to a critical equipment or system is a serious matter, regardless of the number of items in the ship's critical list, and therefor this KPI is kept without a denominator. 3. This KPI uses only one PI.

Formula

[formula]KPI012 = PI029[/formula]

PI029

Number of failures of critical equipment and systems

Ranking calculation example

Step 1: Calculate KPI value

PI029	Number of failures of critical equipment and systems	= 1
[formula] KPI012_{Value} [/formula]	[formula] = PI029 [/formula]	[formula] = 1 [/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] KPI012_{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 KPI012 Failure of critical equipment and systems, 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.
