KPI010 | Drydocking planning performance V4.0
Key Performance Indicator
This KPI expresses the company’s ability to plan the drydocking operation (e.g. predictable costs, good budgeting and scheduling).
Basically it expresses the percentile deviation from planned costs and duration. To avoid penalization of ship managers striving towards minimizing time and cost at drydock, any cost or time deviation between 0 and minus 10% is disregarded (to be interpreted as 'according to plan').
As the KPI expresses deviations both positive and negative, the KPI Value is always converted to a positive value.

Formula
[formula]KPI010 = (\frac{\mbox{| }PI002 - PI005\mbox{ |}}{PI005} + \frac{\mbox{| }PI001 - PI004\mbox{ |}}{PI004})*100\%[/formula]
| PI001 | Actual drydocking costs |
| PI002 | Actual drydocking duration |
| PI004 | Agreed drydocking budget |
| PI005 | Agreed drydocking duration |
Ranking calculation example
Step 1: Calculate KPI value
| PI001 | Actual drydocking costs | = 3.9M US$ | |
| PI002 | Actual drydocking duration | = 16 days | |
| PI004 | Agreed drydocking budget | = 4M US$ | |
| PI005 | Agreed drydocking duration | = 14 days | |
| [formula] KPI010_{Value} [/formula] | [formula] = (\frac{\mbox{| }PI002 - PI005\mbox{ |}}{PI005} + \frac{\mbox{| }PI001 - PI004\mbox{ |}}{PI004})*100\% [/formula] | [formula] = (\frac{\mbox{| }16 - 14\mbox{ |}}{14} + \frac{\mbox{| }3.9 - 4\mbox{ |}}{4})*100\% [/formula] | [formula] = 16.8% [/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 10 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] KPI010_{Percentile Ranking} = \frac{cl+05*fi}{N} * 100 = \frac{90+0.5*1}{100} * 100 = 90.50 [/formula]
Interpretation: Based on the above example, we could say that, when it comes to KPI010 Drydocking planning performance, this ship belongs in the 90.50th percentile of the ships that are being compared with based on its ranking criteria in the respective quarter.
