Bently Nevada System One Software Applications

New System 1 Bundling System 1 for Power Generation
Our new condition monitoring platform System 1 for Power Generation is a pre-licensed System 1 package (point size and interfaces) that is designed to meet the needs of power generators.
Application Packages

Application Packages provide the ability to view the plots relevant to a specific type of asset or application. There are a number of software packages available that address many of our customers' most often-requested applications.

Lubricant Analysis Data Import

Bently Nevada System 1 Lubricant Analysis Data Import Application Package allows customers to work with their existing labs to receive lubricant analysis data in a “.csv” (or Excel) format that we have defined for easy lubricant data import into System 1. Once the data is in system 1, general trending, easy correlation of lubricant analysis data with other condition monitoring data, alarm and event trigger configurations, and Decision Support rules can be performed and implemented to provide a better overall picture of machinery health and to help make better decisions regarding plant performance. Correlating lube data with other condition monitoring and process readings reduces missed failures and enables optimization of overall maintenance expenses with minimized negative impact to from an equipment failure mode.

System Extenders

System Extender modules are designed to work in conjunction with one or more types of System 1 applications, providing extended functionality applicable to a particular asset type, data collection method, or optimization task. Available System Extender modules include:

Dry Gas Seal Monitoring

The Dry Gas Seal System 1 RulePak enables customers to understand their seal health and take appropriate action ranging from “run to next outage” to “immediate shut down and repair. This new capability increases the ability to reduce process gas leakage during production runs and reduce flare events due to leakage. It also enables Condition Based Maintenance for compressor dry gas seal system and provides proactive advisories on the most common failure modes enabled at levels below control or protection alarms and trip setpoints. Additionally, machine availability is improved via more intelligent planned maintenance and fewer unexpected outages.

Corrosion and Erosion Monitoring

This extender detects and reports on piping system wall thickness, enabling you to trend and mitigate degradation from corrosion and erosion. Managing wall thickness and other fixed assets presents a costly challenge to most plants. Rightrax with the System 1 platform can integrate the most critical piping and vessel assets into a condition-based maintenance program. Such a program can typically produce a one year ROI based on moving time based inspection costs to an on-line condition monitoring infrastructure and management program.

GEnyus System 1® System Extender

Combines the domain expertise derived from an installed fleet of 6,500 GE Oil & Gas reciprocating compressors, with more than 40 years of Bently™ Nevada condition monitoring experience on recips, to create a powerful package that harnesses all of this knowledge – and available in a tightly integrated component of System 1 software.

Impulse/Impact Rulepak

Traditionally, protection bands from the Bently Nevada 3500/70M monitor and threshold alarms from other 3500 monitors alert users to the problem areas within these data sets. The Impact/Impulse RulePak builds on this proven foundation to provide powerful real-time analytics on your reciprocating compressor data, integrating synchronized pressure, load, and vibration measurements.

EAM/CMMS Interfaces

Interfaces to many of today's most common maintenance management platforms including:

* SAP** R/3** plant maintenance module
* MAXIMO** system from MRO Software and others

Decision Support

Allows users to generate and maintain their own custom rules for use by System 1's standard decision support and notification capabilities.
RulePaks

Pre-configured rules that embed GE mechanical diagnostic expertise for specific machinery types. Individual RulePaks are available for the following:

* Steam Turbines
* Reciprocating Compressors
* Industrial Gas Turbines
* Aeroderivative Gas Turbines
* Electric Motors and others

Strain Gauge

Typical foil strain gauge. The gauge is far more sensitive to strain in the vertical direction than in the horizontal direction. The markings outside the active area help to align the gauge during installation.

A strain gauge is a device used to measure the strain of an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate.As the object is deformed, the foil is deformed, causing its electrical resistance to change. This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor.

Physical operation

A strain gauge takes advantage of the physical property of electrical conductance and its dependence on not merely the electrical conductivity of a conductor, which is a property of its material, but also the conductor's geometry. When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, changes that increase its electrical resistance end-to-end. Conversely, when a conductor is compressed such that it does not buckle, it will broaden and shorten, changes that decrease its electrical resistance end-to-end. From the measured electrical resistance of the strain gauge, the amount of applied stress may be inferred.

A typical strain gauge arranges a long, thin conductive strip in a zig-zag pattern of parallel lines such that a small amount of stress in the direction of the orientation of the parallel lines results in a multiplicatively larger strain over the effective length of the conductor—and hence a multiplicatively larger change in resistance—than would be observed with a single straight-line conductive wire. Strain gauges measure only local deformations and can be manufactured small enough to allow a "finite element" like analysis of the stresses to which the specimen is subject. This can be positively used in fatigue studies of materials.
