Description
The KPI expresses the number of Lost Time Injuries (LTI) among the crew per million exposure hours.
Interpretation
This KPI expresses the company’s ability to safeguard crew against injuries and fatalities.
Calculation Period | 12 month rolling year |
Scope | Ship level |
Unit | Cases/Million Hours |
KPI Value 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
Ranking calculation example
Step 1: Calculate KPI value
PI030 | Number of fatalities due to injuries | = 0 | |
PI037 | Number of lost workday cases | = 1 | |
PI046 | Number of permanent partial disabilities | = 0 | |
PI047 | Number of permanent total disabilities (PTD) | = 0 | |
PI063 | Total exposure hours | = 87600 | |
![]() | ![]() | ![]() | ![]() |
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 33 and you are the onlyship 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).
Interpretation: Based on the above example, we could say that, when it comes to KPI017 Lost time injury frequency, this ship belongs in the 67.50th percentile of the ships that are being compared with based on its ranking criteria in the respective quarter.
Explanatory Note
Exposure hours are 24 hours per day while serving onboard. Note that injuries during off duty on board are also included.
LTI is the sum of Fatalities, Permanent Total Disabilities, Permanent Partial Disabilities and Lost Workday Cases.
