KPI007 | Contained spills V4.0

Key Performance Indicator

This KPI expresses the company's ability to avoid spills.

Interpretation	Contained spills covers liquid as defined under MARPOL Annex I. Contained spills in secure areas such as Engine rooms are not counted.
Notes	1. Sustainability is a key issue within transport. The company should strive towards zero accidental releases of substances defined as dangerous to the environment even though the incident's impact in this case is reduced as the spill is contained onboard the ship. 2. This KPI is complementary to the KPI "KPI028 Releases of Substances" as defined by MARPOL (Annex I to V), to the environment. Some spills are contained but still represent an incident that should be recorded. 3. This KPI uses only one PI.
Unit	Number of contained spills
Scope	Ship level
Calculation period	Quarterly

Formula

[formula]KPI007 = PI024[/formula]

PI024

Number of contained spills of liquid

Ranking calculation example

Step 1: Calculate KPI value

PI024	Number of contained spills of liquid	= 2
[formula] KPI007_{Value} [/formula]	[formula] = PI024 [/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] KPI007_{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 KPI007 Contained spills, 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.
