Interpretation	This is done by counting the number releases of substances (PI053) and oil spills (PI055).
Notes	Due to difficulties in measuring the actual volume/quantity of a spill or release, the KPI focus on the number of incidents. All releases of oil and any substances to the environment, as covered under MARPOL Annex I to V is to be recorded and counted as an incident. The minimum quantity of release of substances under MARPOL Annex I to V, to be recorded, is as per the company's Safety Management System.

Rating Formula

[formula] \begin{align} \displaylines { KPI_{Value}\\ KPI_{MinReq} = 1\\ KPI_{Target} = 0 } \end{align} [/formula] [formula] KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} [/formula]

Rating Example

KPI Value	= 1
KPI MinReq	= 1
KPI Target	= 0
KPI Rating	[formula]=KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} = 100 \times \frac {(1 - 1)} {(0-1)} = 0[/formula]
