Advanced Inspection and Analysis Tools
Quest Reliability, complemented by the technologies of its parent company, Quest Integrity Group, applies a portfolio of innovative, advanced inspection and fitness-for-service assessment tools; representative technologies include:
Select Recent Projects
Fitness-For-Service Assessment of Steam Turbines
An inspection of a steam turbine disc showed indications of defects. A stress analysis and fracture mechanics assessment was carried out which proved that the turbines were actually fit for service and prescribed a required inspection frequency specific to the asset and conditions.
Remnant Life Assessment of High-Energy Steam Pipework
Defects were discovered in terminal welds in high energy steam pipework. Quest Reliability performed a critical engineering assessment to predict the time for the flaw to grow to the maximum tolerable size, before resulting in prospective failure. The plant returned to service without delay, informed with an appropriate inspection schedule for the steam pipework.
Remnant Life Assessment of an HP Feed Water Heater
Quest Reliability calculated the safe number of starts required before a known flaw would reach critical size to estimate the remaining service life of a high pressure feed water heater. The client was provided with a recommended inspection schedule to safely manage the heater through its remaining life.
