Remote Monitoring and Diagnostics Service

Monitoring and Diagnostics Service helps aeroderivative turbine plant operators improve availability, reliability, operating performance, and maintenance effectiveness. Monitoring of key parameters by engine experts may lead to early warning of equipment problems and avoidance of expensive secondary damage. Diagnostic programs seek out emerging trends, prompting proactive intervention to avoid forced outages and extended downtime. The ability for GE engineers to view real-time operation accelerates troubleshooting and sometimes removes the need for service personnel to visit the plant.

GE Energy developed the Monitoring and Diagnostics System (M&D) to complete its comprehensive world-class service and support network.

System Functionality

• GE’s Monitoring and Diagnostics System includes on-site hardware and software, which retrieves operating data from each plant’s control system and makes it available for transmission to GE’s centralized M&D offices.

• Operating data is transmitted from the site over a standard telephone line, either on a continuous basis via a private Internet network, or in a periodic downloading session.

8.2.25.1 System Overview (Cont)

• The central office archives the operating data, conducts diagnostics on key parameters, and provides all data necessary for displaying or trending.

Site Requirements

• A dedicated phone line or Internet connection must be available to access the Monitoring and Diagnostics System. If cellular data service is adequate at the site, GE may be able to provide a cellular modem.

• The plant control system must be configured to send data to a serial or Ethernet port.

• Mounting space and available power must also be supplied for the onsite M&D System equipment.

8.2.25.2 Product Features

The Monitoring and Diagnostics System enables aeroderivative gas turbine operators to access real-time remote monitoring, early problem identification, and proactive diagnostics.

Key features include:

On-Line Monitoring

• On-line, real-time monitoring allows GE specialists to be on-line to support maintenance and operations personnel.

• On-line monitoring enables quick-response troubleshooting by factory experts, which may result in faster detection and corrective action to avoid potential forced outages.

Accelerated Troubleshooting Support from Factory Experts

• Internet access to the database and on-line monitoring by GE service network enables remote assistance to the customer’s site.

• Certain faults can be diagnosed and corrected without a site visit by GE service representatives and engineers.

• Experienced LM monitoring analysts incorporate factory knowledge and enhanced service for diagnostics, parametric trending, and maintenance planning.

Customer Notification Report

• Customer Notification Reports (CNR) are issued to document anomalies and submit recommended actions for correction.

Product Features (Cont) Customer Notification Report

• Selected conditions will trigger early warning alerts to M&D Center monitors; the center analysts will then escalate the issue to the Customer Satisfaction Manager or directly to the site, along with CNR that documents the observations and recommended corrective action.

Vibration Monitoring System

• The Vibration Monitoring System complements the standard monitoring service by providing early and accurate detection of excessive vibration in the gas turbine.

• The optional Vibration Monitoring System is designed to detect and filter discrete frequencies and display vibration magnitudes directly related to specific problems.

• The system can be custom-designed to filter for any type of problem frequency, ensuring a more sensitive vibration signal for evaluating long-term degradation.

Access to M&D Data

• The M&D Website provides customers secure access to their plant’s data via the Internet.

8.2.25.3 Service Benefits

Performance capabilities provided by GE’s Monitoring and Diagnostics Service include:

Early Warning of Changing Conditions

• Active monitoring by factory engineers may provide early warning of changing operating conditions, thus prompting appropriate on-site action and allowing proactive maintenance scheduling.

• The Anomaly Alert and Escalation Process documents automated early warning alerts, trend shifts, and instrumentation faults in order to help avoid outages and equipment failure.

Proactive Recommendations for Action

• Diagnostic programs seek out emerging trends and alert monitoring personnel; this enables proactive intervention against potential outages and extended downtime.

• Daily trending of key parameters by factory experts may lead to early warning of equipment problems and avoidance of expensive secondary damage.

• Factory assistance to on-site personnel speeds DLE gas turbine control mapping process.

• When trips and failed starts are detected, GE support organizations are notified, alerting them to the possible need for assistance or outage cause investigations.

Reduced Downtime

• The Monitoring and Diagnostics Service may reduce plant downtime and costs by supporting investigations of systems such as the gas fuel system, purge valves, and sensory devices.

• LM monitoring provides advanced knowledge, quicker resolutions, and optimal

performance, which have resulted in an average down-time reduction of three days per gas turbine each year.

Optional Features

The following features are available as options to the standard M&D service:

• Independent vibration monitoring system.

• Wireless or landline communications management from site for data transmission.

• Control system setup for M&D service.

8.2.25.4 Pricing

Annual pricing is dependent upon number of run hours per year, level of service and features desired as well as your plant operating profile. Standard service is offered on an annual fee basis, which includes on-site equipment. Some options may require upfront setup charges and/or annual fees. Contact your GE service sales representative for a customized proposal.

8.2.25.5 Contracts

Monitoring and Diagnostics Service is available under annually renewable or multi-year contracts, and may be included in Contractual Service Agreements or as independent service.

M&D service is offered with the limitation that GE assumes no greater or lesser liability than it has under the terms of any other contracts as a result of the application of the on-site monitoring equipment and M&D System or use of data retrieval software to the monitored units. Also, GE shall not be responsible for failing to monitor the OSM or failing to notify the unit’s owner of abnormalities.
