Remote Digital Video Inspection - RDVI™ is the newest advanced inspection service offering from Quest Integrity Group. RDVI enables visual inspection of nearly every plant system and component without confined space entry or costly disassembly. This inspection method utilizes highly skilled and experienced technicians deploying a wide array of video borescopes, remote operated cameras, robotic crawlers and specialized tooling to deliver clear, concise visual data. All RDVI activities are supported with comprehensive detailed reports including all pertinent data points and images to document asset health.
Common inspection types include:
Baseline. Quest Integrity can provide detailed video documentation of welds, components, piping systems and vessels. RDVI baseline exams provide invaluable reference data, enhance construction practices and aid in future troubleshooting.
Troubleshooting. Diagnosing plant ailments can be painstaking and time consuming. RDVI supports cost effective location and isolation of plant anomalies by eliminating or reducing system and/or component disassembly. It also enhances plant troubleshooting efforts in a variety of methods such as verifying mechanical positioning or effective operation, revealing system cleanliness and identifying foreign material.
Outages and turnarounds. Quest Integrity’s RDVI team aids outage and turnaround activities in the following methods:
- Evaluate system condition prior to commencing work. RDVI is used to assess structural integrity, validate drawings or verify system cleanliness prior to more prominent outage work. This simple step enhances preparedness and may save days of idle time and/or rework.
- Verify system processes. RDVI can locate and identify cavitation, erosion/corrosion, coating deterioration and scale formation. The internal views of systems and equipment enable cost saving changes to plant operations and water chemistry programs.
- NDT. RDVI is commonly used as a standalone inspection technique in place of direct visual examination. It offers greater coverage due to easily overcoming challenges of distance, angle of view and limited lighting. RDVI enables greater inspection coverage, inspection repeatability and data comparison, and it may be used to compliment other NDT results by validating findings and identifying areas for further examination.
- System/component closeout. Foreign material can be introduced to a system in a variety of ways and represents a serious threat to personnel and plant safety. As a QA/QC measure, Quest Integrity provides foreign object search and retrieval services. Prior to closing out components such as turbines, condensers and heat exchangers, the RDVI team conducts a thorough inspection and employs robotic retrieval instruments to remove all foreign debris.
RDVI is a minimally intrusive visual inspection technique that reveals critical data pertaining to asset health and plant operability. Used in conjunction with preventative maintenance programs and other nondestructive testing methodologies, RDVI supports safe and efficient plant operations and increased productivity.For more information, visit www.QuestIntegrity.com/RDVI or call (855) 630-RDVI (7384).
