“QHi is now focusing more resource into the Oil & Gas sector which is increasingly adopting the concept of Exertherm™ Continuous Thermal Monitoring.”
London, UK (PRWEB UK) 28 August 2012
QHi Group pioneered the application and benefits of advanced infrared technology in industry with its unique non-contact, non-powered, vendor neutral Exertherm™ Continuous Thermal Monitoring system.
The battle to gain acceptance that continuous thermal monitoring of mission critical electrical circuits is the new ‘best practice’ via placing small, plastic, non-contact Exertherm™ IR sensors INSIDE electrical panels to directly and continuously monitor for hotspots has been extensive, as it required ‘changing the way an industry thinks’.
Due to the nature of the Oil & Gas industry, comprehensive Asset Integrity Management presents a growing and constant challenge. Facilities must be able to demonstrate effective AIM for major hazard areas including, fire and explosion integrity, electrical and control systems integrity and mechanical / process plant integrity. Aging critical electrical equipment often results in increased levels of operational risk, as it has undergone several intervention maintenance procedures over it’s life.
The tangible benefits and advanced levels of protection provided by Exertherm™ facilitate enhanced Asset Integrity Management via:
- increased uptime through predictive fault detection
- trend analysis, enabling equipment degradation to be monitored & extended periods between intervention maintenance
- electrical failure risk mitigation / enhanced health and safety
As a result of Exertherm™ being permanently installed inside the panel and obtaining real-time data, it removes both luck and subjective operator dependence, as data supplied is continuous, objective and integrated – enabling comprehensive management of electrical/mechanical assets.
These benefits are the key drivers to the increasing global acceptance for continuous thermal monitoring technology being the new ‘best practice’ for high downtime industries.
This has been represented in recent years where the Exertherm™ continuous thermal monitoring system is increasingly being specified into major Oil & gas projects globally, including Abu Dhabi ( Gasco), Australia ( Gorgon, & Wheatstone), Brazil, Mexico and Kazakhstan.
In regards to measurement of equipment performance required for comprehensive AIM, HSE state that appropriate measures would include frequently monitoring/inspecting and recording data for trend analysis.
This should comprise of various operations data, including temperature, pressures, load cycles etc. enabling root cause analysis to be undertaken to highlight where/if any problems are arising before they take effect. Faults are more likely to occur in the following situations:
o High cycling rate of temperatures, pressure loads or flexing
o Operating at the limit of, or beyond its original design
A recent enhancement to the Exertherm™ technology, tackles these issues. QHi recognized that the Oil & Gas industry operates major installations utilizing dual feed power which are operated at low load ( typically below 40%), to enable load switching between feeds for operational and / or maintenance. Currently there is no method which will verify that compromised joints do not exist on circuits operating at low load; even periodic scans will not identify these, as there is insufficient load to generate excess heat. The danger is when additional load is applied to such circuits/joints.
LoadMap™ uses innovative technology to enable alarm thresholds to be dynamically adjusted to suit the load being applied to the circuit. This enables verification that there are no “hidden” problems prior to load switching activity. A further benefit which LoadMap™ can provide is verification that bus temperatures are within the applicable ANSI / EIC standards.
This new, vendor neutral, innovative technology, has already been included in some major Oil & Gas projects with the support of the power equipment OEM’s involved.
Operating globally from offices in the UK, Europe and the USA the QHi-Group provides a new approach to mission critical monitoring, delivering a comprehensive and unrivalled range of solutions from continuous thermal monitoring through to the management of complex energy systems…
