Dresser-Rand's diagnostic modules help increase machinery availability, improve productivity and reduce operating costs
Dresser-Rand Group Inc. has introduced two diagnostic modules for its Envision suite of condition monitoring software. The modules work individually or in tandem to provide information that helps increase machinery availability, improve productivity and reduce operating costs.
The Envision Compressor Performance Module (CPM) provides operators with real-time and historical centrifugal compressor performance calculations. Data is primarily gathered from the plant’s existing control interface to minimize installation time and cost. With Envision CPM, users assess the compressor train’s performance relative to factory determined performance maps. This information allows operational and maintenance activities to be planned ahead of a required shutdown, reducing the impact on production and enabling corrective action to be determined before servicing the compressor.
The second module, D-R’s Envision Health for Journal Bearings Vibration Analysis, aids in the early detection of incipient problems in rotating equipment — as much as one to nine months before a problem deteriorates to unit failure or lost production. By having advanced warning and problem diagnosis, equipment operators can once again plan ahead for operation and maintenance activities.
The reporting tool allows users to select from multiple formats of graphs, or create trends from historical data. Alarms can be sent to designated e-mail addresses. All graphs, data and views are available remotely through a web-based interface running on a standard PC. Since the Envision software suite offers worldwide access, users can work with the modules whether they’re stationed on-site or elsewhere.
