Why is POB evolving into e-POB? 

Personnel On Board (POB) is evolving into Electronic-Personnel On Board (e-POB) because offshore and industrial hazardous area sites need personnel information that is faster, more accurate, and easier to act on. 

Instead of relying only on static headcounts or manual updates, e-POB helps organizations build a live view of who is present, where people were last detected, and how may need to be accounted for during an incident. 

From headcount to operational insight 

Traditional POB processes are built around a simple but essential question: how many people are on site, on board, or inside a facility? 

That information still matters. However, many operational environments are now too dynamic for a simple headcount alone. This includes: 

• Offshore platforms and FPSOs (Floating Production Storage and Offloading)

• Oil and gas facilities  

• Chemical plants  

• Pharmaceutical manufacturing sites  

• Mines  

• Refineries  

• Utilities  

• Other hazardous or highly regulated industrial sites. 

In these environments, contractors may arrive for short-term work. Visitors may move between controlled areas. Workers may transfer between zones, vessels, shifts, or remote parts of a site. 

During routine operations, these movements can create administrative complexity. During an incident, they can create uncertainty. 

What makes e-POB different? 

The move from POB to e-POB is not just about replacing paper with software. It is about making personnel data more current, connected, and useful. 

An e-POB approach can bring together information from systems such as: 

• Access control – Showing who has entered or exited specific areas and helping validate site attendance. 

• Visitor management – Ensuring visitors are included in the live personnel record rather than sitting in a separate sign-in process. 

• Contractor management – Making it easier to track temporary or short-term workers, verify time on site, and reduce invoice leakage caused by inaccurate attendance records. 

• RFID (Radio Frequency Identification) – Providing a way to identify people through cards, badges, or tags. 

• RTLS (Real Time Location System) – Adding real-time location visibility so teams can understand where people were last detected, identify movement patterns, and spot potential productivity bottlenecks. 

• Mobile devices – Supporting location updates, worker interaction, or emergency communication. 

• Fixed detection points – Confirming movement through key locations such as entrances, exits, controlled zones, or muster points. 

By connecting these data sources, e-POB helps create a more accurate and useful picture of who is present, where people were last detected, and what that information means for safety, contractor oversight, audits, reporting, productivity, and operational decision-making. 

How Extronics supports the move to e-POB 

Extronics (BARTEC’s Connectivity & IoT brand) supports e-POB by providing the RTLS tracking technologies that help organizations capture and use personnel location data in hazardous and industrial environments.  

Our RTLS product range includes solutions for tracking personnel and assets, with options designed for harsh locations and potentially explosive atmospheres, including ATEX, IECEx, and cMETus certifications. The range supports key use cases such as location tracking, worker safety, asset management, and automatic mustering. 

A typical Extronics supported e-POB system is built around four key building blocks: 

1. Location sources: Wi-Fi access points, Bluetooth anchors, or GPS are used to determine tag location. For hazardous areas, our wireless enclosure range can house the customer’s preferred Wi-Fi hardware, while our battery-powered iTAG XB40 BLE anchors provide a lower-cost option where installing additional Wi-Fi infrastructure is difficult or expensive. In outdoor areas, GPS is typically used as the preferred location source by the Extronics Location Engine. 
2. Active RFID (Radio Frequency Identification Devices) worker safety tags: The iTAG X-Range of worker safety tags provides rugged, flexible RFID devices for hazardous areas and harsh industrial environments. Available in Wi-Fi, LoRa or Cellular connectivity options, the range supports different functionality depending on site requirements.  
3. Your chosen communication technology: Our iWAP and EXgate range of wireless enclosures are designed to safely deploy the customer’s preferred wireless hardware in hazardous areas, supporting reliable communication between tags, anchors, access points, and the wider system.
4. Extronics Location Engine: Allows the site’s location technologies to be configured to your site map, connecting directly to the MobileView visibility software or a third-party platform via an API. It processes location data from Wi-Fi, BLE, GPS, and other supported sources to provide actionable location data for personnel and assets.   

Why e-POB Needs to Fit the Site 

This flexibility matters because e-POB is not a one-size-fits-all application. The right approach depends on the site layout, risk profile, existing infrastructure, accuracy requirements, certification needs, and operational goals. 

For example: 

• Refinery – Contractors may move between process units, maintenance areas, permit-controlled zones, and muster points during a shutdown or turnaround.  

• Mine – Personnel can be spread across shafts, tunnels, workshops, laydown areas, restricted zones, and remote surface locations.  

• Offshore FPSO – Crew movement often spans accommodation modules, helideck areas, process decks, engine rooms, control rooms, and muster stations.  

• Pharmaceutical manufacturing site – Employees, contractors, and visitors may move between production suites, cleanrooms, laboratories, warehouses, and controlled access areas.  

• Chemical plant – Workforce visibility can support operations across tank farms, loading bays, production areas, control rooms, maintenance workshops, and emergency assembly points. 

By matching the RTLS approach to the site, organizations can build an e-POB system that reflects how people actually move through the facility. This helps ensure personnel data is not just available, but useful during routine operations, planned work, and emergency response. For more on why RTLS needs to be designed around real site conditions, read Designing Practical RTLS for Hazardous Areas: Moving Beyond the Turnkey Myth. To explore available technologies, view our RTLS product range. 

Bringing personnel accountability into the digital age 

POB is evolving from static records to live visibility. e-POB helps teams see who is present, where people were last detected, and how that information can support safer decisions.
