KPI032 | Ship availability V3.0
Key Performance Indicator
The KPI expresses the deviation between the ship's actual unavailability and the planned unavailability. It calculates the ship utilization as a percentage of the total utilization time available during the rolling year (24 x 365). By doing this, the sensitivity of the KPI to small changes in PIs is decreased while at the same time, the case of having zero planned unavailability (PI062) is also covered.
| Interpretation | This KPI expresses the DOC holder’s ability to comply with the plan for the ship's availability. |
| Unit | % |
| Scope | Ship level |
| Calculation period | Rolling year |
Formula
[formula]KPI032 = \frac {(24 \times 365 - PI062) - PI003} {24 \times 365 - PI062} * 100\% [/formula]
| PI003 | Actual unavailability |
| PI062 | Planned unavailability |
Example
| PI003 | Actual unavailability | = 23 |
| PI062 | Planned unavailability | = 18 |
| KPI Value | Vessel availability | = 99.74% |
Rating Formula
[formula] \begin{align} \displaylines { KPI_{Value}\\ KPI_{MinReq} = 97\\ KPI_{Target} = 100 } \end{align} [/formula] [formula] KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} [/formula]
Rating Example
| KPI Value | = 99.74% |
| KPI MinReq | = 97% |
| KPI Target | = 100% |
| KPI Rating | [formula]=KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} = 100 \times \frac {(99.74 - 97)} {(100-97)} = 91[/formula] |
