Red Zone Monitoring Solution

Locate. Alert. Protect

Crew Hawk redefines Red Zone management for personnel. By monitoring hazardous working environments in real-time, this comprehensive hardware and software solution actively tracks individuals and equipment, providing anonymised feedback and information that focuses on safe operations and minimising risk.

Crew Hawk helps configure exclusion zones around hazardous areas and energised machinery. Whenever an individual breaches these zones, their wearable Crew Hawk personal locator immediately triggers an alarm, both on the device and at the control station.

Sensors actively track the real-time location of people, equipment, and assets with a 30cm accuracy, thereby eliminating the need for a direct line of sight. Anonymised location tracking means personnel are protected whilst retaining their privacy.

When an individual enters an exclusion or Red Zone, Crew Hawk promptly triggers an alarm, sending notifications to both the individual’s personal locator and the area authority. Notably, Crew Hawk delivers a personal alarm to workers in the line of potential risk, warning them they have breached a marked zone and allowing them to take corrective action.

By streaming data from the sensors to Crew Hawk Analytics, the system actively enhances safety and operational efficiency, and ultimately lowering the number of incidents and reducing downtime. This optimal Red Zone monitoring solution actively contributes to risk mitigation in the most challenging environments.

How It Works

Crew Hawk empowers users to set up perimeters or geo-fences in the working environment. Users can configure a static geo-fence, or Red Zone, around areas that pose the greatest risk to personnel. As soon as someone breaches this area, their Personal Locator will immediately trigger an alarm. Simultaneously, the area authority will receive an alert specifying what (or who) is causing the alarm.

For dynamic situations, a geo-fence can be configured around energised equipment or machinery. This zone moves in tandem with the equipment, and individuals receive alerts if they enter these zones.

Optionally, users can align Crew Hawk with drilling controls to pause or stop moving equipment, ensuring the protection of workers in the line of potential risk. This is how Crew Hawk redefined the red zone monitoring solution.

IIoT network

Red Zone monitoring solution triangulates personnel locator in a hazardous area.

Wireless gateways strategically positioned around the perimeter of a work area triangulate the position of each individual’s personal locator. This ensures an accurate, real-time view of the work area and the movements of individuals within it.

Red Zone Digital Twin

Crew Hawk creates a real-time digital representation of the work area, allowing the area authority to directly view the Red Zone, thereby enhancing situational awareness and ensuring the safety of the crew.

E-stop Functionality

Red Zone monitoring solution has E-stop functionality system on dynamic zones.

Crew Hawk identifies the moment equipment becomes energised and promptly initiates a dynamic Red Zone around it. Should an individual breach this zone, the equipment automatically pauses, preventing potential escalations and mitigating risk – keeping personnel and equipment safe.

Case study: NOV Control System Integration – a Red Zone monitoring solution

Crew Hawk seamlessly integrates with NOV’s control and alarm system, ensuring the operator receives prompt notifications of breaches and enhancing awareness of activities in the work area. Additionally, the system integrates with ACS (Cyberbase) and ZMS (Amphion) to halt and prevent machines from moving if personnel are inside Red Zone areas.

Performance dashboards offer an overview of operational and safety statistics. Additionally, customisable timeframes unveil individual locations and zone violations within a particular period.

Playback Feature

As part of the Red Zone monitoring solution, there is a playback showcasing the crew movement on the area.

For a more in-depth investigation of zone violations or incidents in a work area, the playback feature enables users to observe the movement of individuals leading up to and following a zone breach or incident.

Work Area Heatmaps

As part of the Red Zone monitoring solution, there is a heatmap showcasing the crew movement on the area.

Heatmaps of the work area showcase the locations of individuals during an operation. This information can then be used to further optimise operating procedures, people placement, and area layout.

“The real-time audible alerts triggered upon zone breaches minimize the time our people spend in the red zone to the lowest practical level, and the comprehensive analytics allow us to measure procedural adherence and human factors for the first time.”
