1. Why Escalation Exists as a System
Distress, urgency, and safety calls are not emotional labels.
They are graduated control signals designed to:
- prioritise attention
- clear communication channels
- summon appropriate assistance
- protect time and margin
Escalation exists because waiting for certainty is unsafe.
2. The Three Escalation Levels Explained
The system is deliberately simple:
- SECURITÉ → hazard information
- PAN-PAN → serious difficulty, not yet life-threatening
- MAYDAY → grave and imminent danger
Each level exists to be used before the next one becomes unavoidable.
If you wait until MAYDAY feels obvious, it is already late.
3. Safety (SECURITÉ): Early Warnings That Prevent Emergencies
SECURITÉ is used to warn others — not to ask for help.
Typical uses include:
- navigational hazards
- reduced visibility
- heavy traffic situations
- weather threats
SECURITÉ prevents escalation by changing other ships’ behaviour early.
Most collisions avoided never become incident reports — because someone spoke early.
4. Urgency (PAN-PAN): When the Situation Is Serious but Stable
PAN-PAN exists to buy time.
It signals:
- loss of manoeuvrability
- steering or propulsion degradation
- medical emergencies
- man overboard (initial phase)
PAN-PAN tells others:
“This may get worse — be aware and keep clear.”
PAN-PAN is not an admission of failure.
It is professional risk disclosure.
5. Distress (MAYDAY): When Delay Becomes Dangerous
MAYDAY is reserved for grave and imminent danger.
It is used when:
- the ship is no longer self-recoverable
- lives are threatened
- immediate assistance is required
MAYDAY is not about drama.
It is about activating rescue before options disappear.
Late MAYDAY calls are one of the most consistent findings in fatal incidents.
6. Escalation Is Reversible — Silence Is Not
Escalation can always be downgraded.
A MAYDAY can be cancelled.
A PAN-PAN can be stood down.
Silence cannot be reversed.
Many crews delay escalation because they fear embarrassment or overreaction.
Accident history is clear:
False alarms are forgiven.
Late alarms are fatal.
7. DSC vs Voice Escalation
DSC and voice serve different roles.
DSC:
- alerts automatically
- transmits identity and position
- guarantees attention
Voice:
- explains the situation
- coordinates response
- updates developing conditions
DSC without voice leaves responders blind.
Voice without DSC risks being unheard.
Professional escalation uses both.
8. Who Decides to Escalate on the Bridge
Escalation authority must be explicit.
Normally:
- the Master authorises escalation
- the OOW may initiate urgency or distress if delay risks life
If authority is unclear, escalation will be delayed.
In emergencies, delay is the real error — not escalation.
9. Common Escalation Failures in Accidents
Accident investigations repeatedly show:
- crews waited “to see if it improved”
- concern was internalised, not transmitted
- escalation occurred only after control was lost
- distress calls were incomplete or late
Escalation did not fail.
Decision-making failed first.
10. Professional Escalation Mindset
Professional mariners:
- escalate early
- escalate clearly
- escalate calmly
- downgrade when safe
They understand that escalation is a safety valve, not a judgment.
Good escalation sounds controlled — not panicked.
Closing Perspective
Distress, urgency, and safety calls exist to protect margin, not reputation.
Every serious maritime accident has a moment where escalation would have changed the outcome.
The difference between a near miss and a fatality is often one call made five minutes earlier.
When in doubt, escalate.
You can always explain later —
but you cannot rewind silence.
