Offshore fire safety
How Do Offshore Fires Start?
Offshore vessels and installations bring fuels, electrical systems, and hot machinery into close proximity. When combustible materials meet an ignition source, a fire can develop. Here are four common contributors.
Electrical
Equipment & wiring faults
Damaged wiring, overloaded circuits, and faulty equipment can produce heat or sparks that start a fire.
Chemical
Flammable fuels & reactions
Fuel leaks can release flammable vapours. Incompatible chemicals can also react and generate dangerous heat.
Unsafe Work Practices
Handling & housekeeping
Improper storage, combustible waste, and missed safety procedures can allow fire hazards to build up.
What’s at stake
People
Fires can cause serious injuries and loss of life, putting crews and emergency responders at risk.
Equipment
Damage to vessels, machinery, and infrastructure can lead to costly repairs or replacement.
Operations
Shutdowns, inspections, and repairs can interrupt work and delay a return to service.

IMO FTP Codes
Application
Part 1, §§1.1–1.2: Materials required to be non-combustible are assessed under Part 1. Passing §3 allows that classification, including organic/inorganic mixtures.
Acceptance Criteria of Non-Combustibility
All four averages must meet these limits.
| Test result | Limit |
|---|---|
| Furnace temperature rise | ≤30 °C |
| Specimen surface temperature rise | ≤30 °C |
| Sustained flaming | ≤10 s |
| Mass loss | ≤50% |
Classification Criteria
Dm is the average maximum specific optical density of smoke from three tests at each test condition.
| Material | Maximum Dm |
|---|---|
| Bulkhead surfaces, linings and ceilings | 200 |
| Primary deck coverings | 400 |
| Floor coverings | 500 |
| Plastic pipes | 400 |
Average maximum concentrations at each test condition; laboratory classification limits, not workplace exposure limits.
| Gas | Maximum (ppm) |
|---|---|
| CO | 1,450 |
| HBr | 600 |
| HCl | 600 |
| HCN | 140 |
| HF | 600 |
| SO₂ | 120 |
| NOₓ | 350 |
SO₂: 200 ppm for floor coverings.
