Aarsleff Ground Engineering has invested in the world’s first sensor based rotary rig guard. ‘Safer-G’ from the Equipe Group is a sensor-based guarding system that allows for increased access and productivity whilst operating on site, removing the need for restrictive and fully enclosing guarding systems.
Why did Aarsleff invest in the Safer G?
- Improves our rig productivity
- Improves personnel protection
- Complies with all safety and machinery legislation
- Complies with EN 16228 Parts 1&2
- Compatible with all rig types
- Creates a safer work environment
- Carries FULL CE marking as a safety device
A considerable amount of time in the research and development phase of Safer-G was spent getting the balance right between being able to sense physical persons, whilst maintaining the ability to discount things like muds, liquids and dust particles kicked up in the act of drilling. The system uses state of the art sensor technologies to detect persons encroaching within predefined safeguarded zones. Once a detection is made, the system generates a signal to switch off rotation to prevent any potential entanglement. One of the things that Equipe noticed and were also informed of by the drillers themselves, was the cumbersome and time-consuming nature of rotary drilling guarding. Opening and closing the gates every time a rod or piece of casing needed to be added takes a considerable amount of time, meaning less time is actually spent drilling boreholes. That seemed not only irritating to on-site operatives but also detrimental to business
Keith Spires, Equipe Director, explains:
“Our goal when developing the SAFER G technology was primarily to find a better method of guarding rotary rigs which was developed around the driller’s requirements and not just to satisfy legislation. That said, the new legislation requires rig manufacturers to design a safety system which goes way beyond a physical guard and switch mechanism. We now believe that we have developed a system which does not hinder the driller in his daily work, improves safety, is fully compliant and also greatly improves productivity.”
Safer-G removes the need for gated type guards by providing a safeguarded zone.
Safer-G provides a safety zone between 0.5m from the floor to 1.8m from the floor where operators cannot enter.
Safer-G cannot be easily bypassed or disabled.
Integration of self-checking diagnostics system which ensures the ‘failure to safe’ mechanism is present at all times.
Safer-G can detect an object moving anywhere within a safeguarded zone.
