Most HSE reports start with injury numbers. Those numbers matter, but they only describe what already went wrong. This guide explains HSE key performance indicators on industrial projects. It compares leading and lagging indicators, then gives HSE KPI examples that site teams can act on.
An HSE KPI is a number that tells you whether your health, safety and environmental controls are working. On a shipyard, an offshore modification job or a solar construction site, that means two different questions:
Lagging indicators answer the first question. Leading indicators answer the second. A useful KPI set needs both, because each one covers a blind spot of the other.
A practical working definition separates outcomes from preventive activity. Lagging indicators measure events that have already happened, such as the number or rate of injuries, illnesses and fatalities. Leading indicators are proactive and preventive measures that show whether safety and health activities are working before an incident occurs.
A balanced programme uses leading indicators to drive change and lagging indicators to measure longer-term effectiveness.
| Lagging indicators | Leading indicators | |
|---|---|---|
| What they measure | Outcomes: injuries, illnesses, incidents | Activities and conditions that prevent incidents |
| Timing | After the event | Before the event |
| Typical use | Comparing periods, contractors and projects | Steering the work week by week |
| Main weakness | Small numbers on short jobs, so trends are hard to read | Can turn into box-ticking if not tied to a real hazard |
The most quoted lagging KPI is an injury or illness rate. A commonly used incidence rate per 100 full-time workers is calculated as:
Rate = (N / EH) × 200,000
A worked example: a crew logs 48,000 hours on a refit and records 2 cases. The rate is 2 / 48,000 × 200,000 = 8.3 per 100 full-time workers.
Two practical points before you compare numbers between companies or projects:
On a short project, lagging numbers are often zero or close to it. A zero does not prove the site is safe. It may only mean that the exposure hours are low or that reporting is weak. This is where leading indicators earn their place.
The examples below suit marine, offshore and construction work when they are linked to the actual project hazards:
Leading indicators should follow SMART principles: Specific, Measurable, Accountable, Reasonable and Timely. In practice, ask five questions of every KPI on your list:
For a typical subcontracted crew working under a client's HSE system, a compact set could look like this. Adapt it to the hazards of the actual work scope.
| Indicator | Type | Frequency |
|---|---|---|
| Recordable injury rate (with the base stated) | Lagging | Monthly and at job close |
| Near misses reported per 10 workers | Leading | Weekly |
| Hazard reports closed within the agreed time | Leading | Weekly |
| Planned inspections completed | Leading | Weekly |
| Workers with mandatory training complete before start | Leading | At mobilisation, then monthly |
| Investigations with root cause identified | Leading | Per event |
Which HSE indicators a RAM crew reports depends first on the delivery model. Under workforce solutions, welders, pipefitters, fitters, electricians or complete crews join the client's organisation. The client directs the work and keeps control of scope and day-to-day execution, while RAM handles employment, documentation, mobilisation and workforce administration. In that setup the crew works inside the client's HSE system, and the reporting set is the client's to define.
Under technical subcontracting, RAM organises the trades, supervision and coordination. The contract defines the deliverables, interfaces and acceptance criteria. The HSE reporting then belongs in the same contract: which indicators, which definitions, which base for the injury rate, and how often they are reported.
In both models, the preparation RAM publishes for its oil and gas work comes before the first shift: understand the work, match capability to the task, check qualifications and documentation against what the project asks for, and agree scope, supervision, interfaces and deliverables before anyone travels. The team checks an indicator such as "mandatory training complete before start" at that point. For welding scopes, the team checks the welder's qualification range against the project's WPS and WPQR. If the range does not cover the scope, the project may reject the welder. This can delay a work front.
Timing matters as much as content. For a shutdown, the same page puts it plainly: the window matters more than the headcount. In a short window, a monthly indicator gives too few data points. Therefore, agree the tracking frequency with the crew before work starts.
Pick one or two leading indicators that address the biggest hazards of your current job, track them weekly, and act on what they show. Keep the lagging rate, state its base and definitions, and read it over longer periods. That combination gives a project manager or HSE lead an honest picture of performance, not just a clean report.
RAM's HSE policy documents are on the company policies page. If you are planning a crew for offshore modification work and want to agree the HSE reporting before mobilisation, contact the RAM team.
Short projects can record zero injuries without proving that controls are effective. Leading indicators show whether preventive actions are actually being completed.
Teams should be encouraged to report useful observations without fear of blame. The quality of follow-up and corrective action matters more than forcing a target number.
Only when the projects use the same definitions, calculation base, reporting period and exposure data. Otherwise the comparison can be misleading.
