Headcount before the second alarm.

Active RFID/UWB → live POB · muster readers → roll-call

What buyers actually care about.

Authoritative POB, not a second list. Muster only works when the electronic Personnel on Board (e-POB) roster is the same population that wears badges. Flight/vessel manifests, visitor logs and contractor day-passes must land in one live register — before the alarm, not during it.

Time-to-account and missing-person clarity. Buyers measure drill and incident performance as minutes to a complete headcount, plus a short, actionable missing list with last known location for the Emergency Response Team — not a pretty map of everyone who already mustered.

Resilience when the network is degraded. Real emergencies stress power, radio and WAN. Muster-point readers that work offline, local caches, and a control-room picture that still reconciles when links recover are non-negotiable for offshore and large industrial sites.

Defensible audit for drills and incidents. Regulators, flag states and internal HSE teams want time-stamped who/where/when records. SOLAS-style expectations (clear instructions, defined muster arrangements, realistic drills, recorded outcomes) apply unevenly to FPSOs and MODUs by flag and coastal state — the operational duty of care does not.

Integration with logistics and life-saving systems. Helipass / walk-to-work / cabin allocation, Fire & Gas, PAGA and access control should move people in and out of POB automatically. Manual dual-entry is where the roster and the badge population diverge.

Where mustering programmes fail.

Clipboard POB with electronic theatre. Tags at muster stations mean little if arrivals were never reconciled against the flight list. The failure mode is a clean muster report for the wrong population.

RTLS-first where presence would do. Continuous centimetre tracking across every module is expensive and fragile. Many offshore and industrial programmes succeed with event-based RFID or LF at muster points plus selective locating for last-known search — not full-site RTLS on day one.

No alternate-muster logic. People will go to the wrong station under stress. Systems that only credit the allocated lifeboat create false missings and slow the ERT.

Drill culture that never exercises degraded modes. If every drill assumes perfect Wi-Fi and a calm PA, the first blackout or gas event exposes the gap. Treat offline mustering and last-known location as drill scenarios, not optional extras.

Competitive landscape (advisory view).

Product stacks in this space include Extronics (hazardous-area worker tags, e-POB and locating for offshore emergency response), EPIC POB / Smart-Trac (RFID e-mustering, hotel/cabin and travel-logistics modules), IDENTEC SOLUTIONS Crew Companion (POB, electronic mustering with offline mode, access and flight/vessel-manifest integrations), and workplace platforms such as Savance (access-control-linked mustering and status boards for campuses and industrial sites). Adjacent industrial locating vendors (Litum, Sewio and similar) often attach mustering as a module on a broader personnel platform.

How vendors pitch vs what to buy. Vendors sell speed-to-muster, “100% accurate” headcounts and certified tags. Buyers should purchase: a single authoritative POB source of truth; muster detection that survives partial infrastructure loss; alternate-muster and lifeboat capacity logic; last-known location for search; and integration to logistics and F&G — measured by drill KPIs, not by tag count. TRACIO does not sell POB hardware or mustering SKUs; we scope, select and integrate vendor stacks against those outcomes.
