KPI026 | Port state control deficiency ratio V4.0

Key Performance Indicator

This KPI expresses the company’s ability to avoid deficiencies issued during Port State Control Inspections.

Interpretation	The KPI represents a ratio between the number of reported deficiencies relative to the number of Port State Control Inspections as such the average number of deficiencies per inspection. By defining the KPI as a ratio, benchmarking is feasible even between ships being subject to an uneven number of Port State Control Inspections.
Notes	This KPI is one of three KPIs related to Port State Control Inspections. The three areas covered are; 'Flawless port state control performance' which measures the percentage of Port State Control Inspections resulting in zero deficiencies, 'Port State Control Detention' which measures the total number Port State Control Inspections resulting in a detention and this specific KPI, and, 'Port State Control Deficiency Ratio', which measures the ratio of the total number of issued deficiencies during Port State Control Inspections relative to the total number of Port State Control Inspections conducted. In addition the Port State Control Inspections and deficiencies identified during such inspections are part of the KPIs related to deficiencies identified during any external inspection.
Unit	Deficiencies/Inspection
Scope	Ship level
Calculation period	Quarterly

Formula

[formula]KPI026 = \frac{PI048}{PI049}[/formula]

PI048	Number of PSC deficiencies
PI049	Number of PSC inspections

Ranking calculation example

Step 1: Calculate KPI value

PI048	Number of PSC deficiencies in a quarter	= 12
PI049	Number of PSC inspections in a quarter	= 4
[formula] KPI026_{Value} [/formula]	[formula] = \frac{PI048}{PI049} [/formula]	[formula] = \frac{12}{4} [/formula]	[formula] = 3 [/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] KPI026_{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 KPI026 PSC deficiency ratio, 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.
