Abstract: A technique facilitates tracking and assessing a fatigue life of a tubing string utilizing, for example, estimation of cycles to failure when used in a wellbore operation. The technique may comprise initially determining a fatigue life of a tubing string. Additionally, the techpique comprises utilizing a sensing device, e.g. a magnetic flux leakage (MFL) device, to monitor the tubing string. When an anomaly, e.g. a new defect, is detected by the sensing device, a new fatigue life of the tubing string is determined based on the change. The new fatigue life may be used to estimate a fatigue life in terms of cycles to failure.

Abstract: A technique facilitates prediction of run life. Data relating to a pipe defect is provided to a data processing system for comparison to stored data regarding defects. Additionally, data regarding fatigue life accumulation is stored on the data processing system as it relates to fatigue life of the pipe based on the number of cycles to failure of the pipe without the presence of the defect. The number of cycles experienced by the pipe at the time the defect occurs in the pipe also is determined and provided to the data processing system. The system and methodology further comprise using the data regarding the defect type, the fatigue life accumulation data for the pipe, and the number of cycles experienced by the pipe at the time of the defect to estimate a remaining number of cycles until failure of the pipe.

Abstract: A system and method control an amount of power delivered by a power converter (220) to a solid state lighting load (240). It is determined whether a dimmer (204) is present between a voltage source (201) and the power converter (220) based on a rectified input voltage from the voltage source. When the dimmer is determined to be present, an operating point of the power converter is adjusted to increase the amount of power delivered by the power converter to the solid state lighting load by a compensation amount, so that the increased amount of power is equal to an amount of power delivered by the power converter when the dimmer is not present.
