Our online inspections identify problems that are not easily detected when the plant is offline. They also identify critical issues early for better repair planning. Online inspections include a thermal imaging survey with a FLIR camera. This allows quick identification of casing hotspots and gas leaks, as well as being able to evaluate the condition of expansion joints and penetration seals. Operational checks during the inspection include duct burner flame stability, steam drum level consistency, desuperheaters, pipe support load indicators and condensate preheating. In addition, inspectors pay close attention for unusual noises and vibration may hint at gas-side problems. No shutdown is needed and as there is no use of confined spaces, one HRST inspector alone can cover an entire plant.
