KPI014 | Port state control performance V4.0

Key Performance Indicator

This KPI expresses the company’s ability to have flawless Port State Control inspection.

Interpretation	The KPI counts the number of times where Port State Control Inspections are conducted without any deficiency being reported and divides this number by the total number of Port State Control Inspections conducted during the same period.
Notes	This KPI is one of three KPIs related to Port State Control Inspections. The three areas covered are; Port state control deficiency ratio which measures the ratio of the total number of issued deficiencies during port state control inspection against the total number of port state control inspections conducted, Port state control detention which measures the total number of port state control inspections resulting in a detention and, this specific KPI, 'Flawless port state control performance' which measures the percentage of port state control inspections resulting in zero deficiencies. It could be argued that this specific KPI is overlapping with the KPI 'Port State Control deficiency ratio'. We recognize this view and the latter KPI is kept only as an internal KPI.
Unit	Flawless Inspections/Inspections
Scope	Ship level
Calculation period	Quarterly

Formula

[formula]KPI014 = \frac{PI051}{PI049}[/formula]

PI049	Number of PSC inspections
PI051	Number of PSC inspections resulting in zero deficiencies

Ranking calculation example

Step 1: Calculate KPI value

PI049	Number of PSC inspections	= 4
PI051	Number of PSC inspections resulting in zero deficiencies	= 2
[formula] KPI014_{Value} [/formula]	[formula] = \frac{PI051}{PI049} [/formula]	[formula] = \frac{4}{2} [/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] KPI014_{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 KPI014 Port state control performance, 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.
