The oil & gas industry has long been a leader in the deployment of predictive maintenance technologies in pursuit of improved asset performance.
Predictive maintenance is now the preferred technique for critical assets in many situations, not only because it brings significant cost benefit advantages but also because it improves the level of control that engineers can exert over the future performance of their assets. But while excellent protection and monitoring systems are now widely used for very costly equipment like gas turbines, it has been more difficult to deploy cost-effective solutions for the many pumps, fans, compressors, and other assets used in large numbers at all facilities.
The Artesis predictive maintenance system aims to provide all the benefits of traditional condition monitoring systems at a fraction of the complication and cost. Artesis MCM (motor condition monitor) uses an intelligent, model-based approach to provide complete monitoring and diagnostic capabilities for most electric motor driven equipment.
Each MCM unit covers a complete motor and the equipment driven by it, and is typically installed in the motor control cabinet. Since connections are required only to the motor supply cables, installation costs are low with no need to access the driven equipment for any sensor installation. Once installed, the system trains itself to recognise normal performance, following which it continuously monitors the equipment for possible faults. When such a fault is detected, the system provides a diagnosis of one of a wide range of mechanical and electrical problems, and indicates severity so that the user can make decisions on the most appropriate intervention.
Because the Artesis system is simple to install and requires little user intervention in operation, it combines low start-up costs with the significant benefits of predictive maintenance. Since it doesn’t require any sensor installation on the equipment itself, Artesis MCM is a particularly good solution for inaccessible equipment like submersible and down-hole pumps. The Artesis PCM (plant condition monitor) provides similar cover for generator and alternator systems, and is often used to supplement the capabilities of existing vibration-based monitoring systems.
A wide range of communications options are available, allowing users to integrate the Artesis system with their existing control and data acquisition or maintenance management architectures. Where facilities are spread across a wide geographic area, and may also be difficult to reach, a typical installation will combine automated alerts using email messages with centralised on-line monitoring screens.
