KPI017 | Lost Time Injury Frequency V2.6

Key Performance Indicator

This KPI expresses the company’s ability to safeguard crew against injuries and fatalities.

The KPI counts the number of Lost Time Injuries (LTI) among the crew per million exposure hours. Exposure hours are 24 hours per day while serving onboard. Note that injuries during spare-time on board are also included. LTI is the sum of Fatalities, Permanent Total Disabilities, Permanent Partial Disabilities and Lost Workday Cases. The term ’crew’ refers to any person being part of the ship’s complement. (e.g. officers, ratings, cadets, superintendents). The same complement is also used as basis for calculating the Total Exposure Hours.

Unit	Incidents/Million Hours
Scope
Calculation period

Formula

[formula]KPI_{Value} = \frac {PI030 + PI037 + PI047 + PI046} {PI063 \times 10^{-6} }[/formula]

PI030	Number of fatalities due to work injuries
PI037	Number of lost workday cases
PI046	Number of permanent partial disabilities
PI047	Number of permanent total disabilities (PTD)
PI063	Total exposure hours

Example

A	Number of fatalities due to injuries:	= 0
B	Number of Lost workday cases:	= 1
C	Number of Permanent total disabilities:	= 0
D	Number of permanent partial disabilities:	= 0
E	Number of Total exposure hours:	= 87600 (crew of ten for one year)
KPI Value	Lost Time Injury Frequency	[formula] = \frac {A + B + C + D} {E \times 10^{-6}} =\frac {0 + 1 + 0 + 0} {87600 \times 10^{-6}} \approx 11.41[/formula]

Rating Formula

[formula] \begin{align} \displaylines { KPI_{Value}\\ KPI_{MinReq} = 2.5\\ KPI_{Target} = 0.5 } \end{align} [/formula] [formula] KPI_{Rating} = 100 \times \frac {KPI_{Value} - KPI_{MinReq}} {KPI_{Target}-KPI_{MinReq}} [/formula]

Rating Example

KPI Value	= 11,41
KPI MinReq	= 2,5
KPI Target	= 0,5
KPI Rating	[formula]=KPI_{Rating} = 100 \times \frac {KPI_{Value} - KPI_{MinReq}} {KPI_{Target}-KPI_{MinReq}} = 100 \times \frac {11,41 - 2,5} {0,5-2,5} = 0[/formula]
