Installed sensors and continuous online monitoring are revolutionizing how power plants manage assets and risk by facilitating the transformation to condition-based maintenance routines. With access to near real-time data, condition assessments, and operating trends, operators have the opportunity to safely and intelligently reduce operations and maintenance costs and outage durations, maximize component lifecycles and uptime, and improve overall operating efficiency.

But not all data is created equal and determining what to monitor, where to monitor, selecting appropriate sensors, and determining data frequency are all critical decisions that impact data value. Furthermore, sensor procurement, installation services, data historian/storage, and data analysis are often provided by separate entities, which can lead to implementation challenges and disruptions to efficient data flow.

News & Views, Volume 48 | Considerations of Pin Cracking in Finger Pin Turbine Blade Attachments

By:  Cliff Lange and Matt Freeman

OEMs recommend periodic inspection of pinned finger turbine blade attachments for detection of service-induced damage as part of ongoing rotor maintenance activity. 

This article provides an example where ultrasonic inspection detected cracking in several pins of finger attachments and outlines an engineering assessment to support continued operation and identify a re-inspection interval.  This approach can be applied to other pinned finger blade attachments to determine suitability for service.

PlantTrack App now available

News & View, Volume 46 | Plant Integrity Assistant – There’s an App for That! PlantTrack App Now AvailablePlant engineers must often answer ‘what damage is this piece of equipment susceptible to, and what can we do about it?’ or ‘how much longer can this component continue operating’?   A free app is now available in both the Google Play store and the Apple App store to help answer these and other equipment integrity questions (see figure 1).

The PlantTrack App is a plant integrity assistant that provides life calculators, damage mechanism guides, technical articles, lab sample submittal form, and other functions relevant for plant engineers.  While it is geared towards fossil (both coal and gas) power plants, it has applicability for equipment at other plants as well.  For subscribers to the PlantTrack web application, the mobile app also provides a dashboard view of inspection history, action items, damage tracking results, etc.  Users of the PlantTrack software will recognize some of the features from the ‘PlantTrack Tools’ that have previously been available through a web browser.

News & View, Volume 45 | Life Management for High Energy Piping (HEP)High Energy Piping systems, including main steam and hot reheat piping, are typically very reliable and can often operate trouble-free for decades.  However, due to the combination of pressure and temperature at which such systems operate, a failure can have catastrophic consequences from a safety perspective and in terms of equipment loss.  Because of this and the requirements of the ASME B31.1 Power Piping code, HEP programs – or as defined by Code, Covered Piping Systems (CPS) – are established to ensure that the integrity of the system is maintained throughout their lifecycle.  This article discusses the steps required to implement an HEP / CPS life management program.

A Life Management Program is not synonymous with an inspection program.  Inspections are an important part of an overall program but should be complimentary to the use of analytical tools, real-time monitoring, and laboratory examinations

Expanding Capabilities in Condition-based Pressure-part Integrity Management

News & View, Volume 44 | Real-Time Damage Tracking with SI Technology and GP Strategies’ EtaPro Expanding Capabilities in Condition-based Pressure-part Integrity ManagementStructural Integrity and GP Strategies recently announced an agreement to bring SI’s technology for calculating, tracking, and trending life consumption of piping and boiler components to GP Strategies EtaPRO real-time monitoring platform (Press release here).  SI has a long history with creep and fatigue damage monitoring applications, most recently with the suite of applications available as part of SI’s PlantTrack platform.  The partnership with GP Strategies brings that technology to EtaPRO, which is used worldwide by power-generating organizations to monitor the performance and reliability of their generation assets.

EtaPRO users will benefit from easy integration of SI’s leading-edge Boiler and Piping Component Reliability (BPCR) modules to quantify damage to high-pressure, high-temperature components such as tubing, piping, headers, and desuperheaters. The BPCR modules track and trend accumulated creep and fatigue damage in real time using SI’s proprietary algorithms that combine actual operating data and material condition with a plant’s specific configuration. Plant operators can use the resulting life consumption estimates to guide asset management decisions, such as changes in operating procedures, targeted inspections, or off-line analysis of anomalous conditions.
